do you use Synthetic oil in your car?

[Quoydogs]

So I just typed this in another thread and then found out it was about Syn life and not oil. I guess I stayed up way to late playing red dead Redemption last night.

So anyways I figured I would ask I would like to know how many of you do use Syn. in your car.


I love Synthetic oil. Here are some things you need to know.

#1 It is better in every way and to be honest I don't think it will ever break down regardless of what the test say.

#2 You still need to do regular oil changes. Even thought the oil protects better and last way longer you still get the same amount of dirt in it that you would with conventional oil. Dirt works like sandpaper on your cylinder walls and crank bearings.

#3 If you have a small oil leak with conventional oil you will have a big oil leak with Syn. oil.

#4 This is most important. Unless you engine specifically states to use it. ( IE lt1 motor ) DO NOT put this stuff in your engine until you have at least 30,000 miles on it.

Hope this helps. I am all for it though. I run it in everything I own even down to my little POS Subaru.

Oh One more thing. Never use Pennzoil or Quaker state in anything. They are absolutely the worst oil in the world.

[TailgateNut]

I use Mississippi Delta water 10-30 (10 parts water-30 parts oil)!

[listopencil]

I chop of the hands of obese children and shove them into the engine block. The rendered fat works wonders. I swear by it.

[Hogan11]

chicken fat and bacon grease

[Los Broncos]

Yes I do, oil change every 5,000 miles.

[BroncoBuff]

Synthetic oil has been proven superior over and over.

Mine has synthetic because it came with it ... if it hadn't, I would've probably been too lazy to change over.

[Peoples Champ]

do you work for mobil 1?

[Quoydogs]

do you work for mobil 1?

Nope work for my self. I own a shop and any kind of info helps. Personally I use Castrol gtx 5-30 syn. I use to use Valvoline but I have found that Castrol will stop the ticking in a lifter in my Suby.

sweet, you dont happen to work on German cars like audi's or bmw's or VW's do you?

[broncosteven]

I use Mobil 1 Synthetic in my BMW. She is getting close to 100k and still feels as good as when I pulled her off the lot.

[Broncoman13]

Just got a new Infiniti... It has synthetic and a lot less than 30,000 miles. Hopefully that is what the car calls for. It's what the dealership puts in it so I'd hope they would know.

Sweet,

I will use that for my Audi, I just ask for their best synthetic, but I will start asking for mobil 1.

[Los Broncos]

I use to think I needed an oil change every 3k, but the newer cars from I guess 95 on, only need them every 5k.

What did you get?

One of my mixers just got an M35. Great car. I miss my infinit.(s) Probably going to make the G37 my next car.

[Taco John]

Synthetic oil is an abomination in the eyes of God. Nothing but sweet crude for me.

[Oleg Gordievsky]

Oleg thinking thread is reason for small penis dumbskies to be boasting of their car model.

"I have BMW!"

"Stupid German sonofwhore! I have Inifinity!"

"Both dumbskies! I have Audi. And 2 inches of pecker!"

Oleg is making funny. Calm yourselves!

Oleg never change oil in Volga. Volga is greatest car in world! Long live Soviet engineerings!

I have a Chevy, Oleg .... impressed now?

This.

I use Amsoil, which has been proven to be top notch among synthetics.

[Quoydogs]

Nope I avoid those like the plague, sorry. Although I will say I can work on most anything else.

[Quoydogs]

You better check. Like I said there are some engines manufacturers that want you to run this in your car from the get go. But for the most part syn. is so slick that it will not allow your rings to break in properly. Bad news there. As for why does everyone trust the dealer? No one trusts a car salesman, the same people run the shop as run the salesman. I just don't get it. Most of the dealers here is Portland are more crooked then any of the independent shops, less Goodyear or Firestone I suppose. Those two seem to be the worst.

[Broncoman13]

G35.

2006 but it only had 8k on it and was flawless with exception of one rim having some sort of black mark on it. The dealership just fixed that yesterday. In the meantime I had a 2010 G37 (convertible). I like my 35 much MUCH more than the 37 convertible. I guess I'm just not that big on convertibles.

As far as the 35... awesome. Love driving to work now ;D and I get there a lot faster now, lol. I'd recommend the car to anyone. I had a 94 Honda Prelude while I was in the Air Force. That car was my favorite car... wish I would have never got rid of it. But the G35 is very similar, reminds me of the Prelude when I wash it... but it has about 100 more HP which makes it a lot more fun. Seriously though, if you're thinking about a new car... find a G35.:yayaya:

[uplink]

oil in car, ha ha funny. Is this a Gulf of Mexico oil spill joke? I've been so worried about my new 1st car overheating lately I don't have time to follow the news.

Beautiful, man. One of the few cars I think looks good in white. When mine was at the dealer for service they gave me a 35 loaner. Cream color. Props on getting a good deal on it. I had 2 QX4's, but went to volvo for a sedan. I like my s60, but still wish I would have gotten the 37. Japanese make the best luxury cars, imo... and the G35's flat out fly for a luxury sedan.

Co-worker has a new Mercedes C-class sports sedan, and it doesn't hold a candle to the G-series.

Use salad oil in your car. It's inexpensive and cheap to replace. Your engine on the other hand, may not be. ;D

Thought about getting a BMW 335xi... saw one today in the neighborhood. Sweet car, doesn't look as good as the G35 but more power. The 335xi would have had more miles though, not many of them for sale. I was really lucky with the 35. The guy that owned it only drove it on sunny weekends and on a trip to California and b/c of the low miles I was able to get a 5yr/75k mile warranty for next to nothing... covers windshields too. In fact, they just put the permaguard on the windshield yesterday, must have for Colorado. The cost of the first windshield I go through will pay for the warranty (little pricey for the windshields) and I'm sure I'll go through 4 or 5 in the next 5 years.

[MrPeepers]

yes,,,

08 VW Passat- Mobil One for me. 50k miles so far.

[orange&blue87]

This.

I use Amsoil, which has been proven to be top notch among synthetics.

+1 ... We've had a car for 2 years that had converted over to Amsoil synthetic, and we've continued using it every 6K miles. I've heard it can go much longer between changes, but 6k usually is every 3-4 months on the car so I figure it's worth a change.

[Popps]

At least in LA, you'll pay more for a used BMW because of the name. Nothing against them, they're nice cars... but for my money, the Infiniti offers as much comfort, plenty of power and you'll spend less time at the dealer in the long-run, imo.

[TheElusiveKyleOrton]

Castrol synthetic in my '08 Subaru. Change it myself, and absolutely love the performance.

[BroncoBuff]

Popps, couppla my friends in LA have gone to hybrids just for the Diamond Lane privileges.

The cars are no fun obviously, but Diamond Lanes are the only way to go. They can damn near save your life sometimes.

[IHaveALight]

Oh One more thing. Never use Pennzoil or Quaker state in anything. They are absolutely the worst oil in the world.

Pennzoil Platinum is very good quality oil. The only two synthetic oils thought to be better are Amsoil and Royal Purple. Many people believe that because of the price difference and lack of availability of the other two, that Pennzoil Platinum is the way to go.

Me personally, I use Amsoil 0W-30 with an Amsoil filter. They say this combo is good for 25,000 miles or 1 year whichever comes first. I put it in in August last year and only put on about 7,500 miles a year. So I'll be changing at one year. I'm planning to send a sample in to get tested to see how well it really held up for the year.

My commute is so short, it's ridiculous. I'm extremely lucky. (Well, it was somewhat by design, I suppose.) I'm lucky to put 8K miles on my car in a year. That's probably why I haven't bought anything new in a while. I just can't justify the purchase. I bought my wife a new car. She drives more than I do with the kids and all, so she needs it more than I do.

I've had a tank of gas last me almost a month before. :)

But, yea... if you have a big commute, the D-lane is the way to go, and some stores even offer hybrid parking, here.

[IHaveALight]

I use Mobil 1 Synthetic in my BMW. She is getting close to 100k and still feels as good as when I pulled her off the lot.

From what I understand there are many synthetic oils out there that are better than Mobil 1 for around the same price or a little higher. I'm not sure on this but I heard that Mobil 1 is only a Group III oil. While Group III is considered synthetic, only Group IV is true synthetic and is the superior oil. I think at one point Mobile 1 was a Group IV and that's how they earned their rep. Regardless, do a little research you'll find a better oil.

Here's a chart from Amsoil. Granted it is Amsoil promoting their oil so take it with a grain of salt.

This is true and there are several independent tests that supported these conclusions. :thumbsup:

It should also be noted that Amsoil and Castrol are 0W30 not 5w30

[Cito Pelon]

I've used Amsoil for 25 years. Both engine oil and gear lube. 100k miles maint interval with the gear lube.

I use the 5W-30 and their filters, 12 months or 24000 miles maint interval. Sure is nice to change the oil only once a year. Costs about $8.35/qt, I believe. Order it online, gets delivered UPS.

[Cito Pelon]

This.

Yeah, but the Mercedes is rearwheel drive, same with BMW and Lexus GS sport sedans. I prefer rearwheel drive over frontwheel drive. I believe the Infiniti's are all FWD except the Q45, yes? The Volvo is rearwheel drive, yes?

I've been out of the market for a few years now, so forgive me if I'm not up to date on the latest editions.

I rebuild a lot of motors. The only oil I can tell someone has used is Pennzoil or Quaker state. Everything on the inside will be varnished yellow and the oil pan,valves and heads will be full of sludge.

I really don't know why I hate it, it makes me all kinds of money.

I won't even put Pennzoil in my lawnmower. Hilarious!

[55CrushEm]

A co-worker of mine got me onto synthetic. I always used to think it was a waste of money....cause you still had to change it as frequently as conventional, due to it getting dirty.

Anyway, he has a Toyota 4-Runner with 337,000 miles on it (yes, THREE hundred thirty-seven thousand) miles. And he swears that since day one, he's only been changing his oil every TEN thousand miles.

AMS claims you can go for 25k or one year... but really, in a year's time that is really only saving you about $100. And, if you have a newer car that is still under warranty, going that long between oil servicing could void your warranty. Not really worth it to save $100. But, if you have a car that is out of warranty and you're bad about changing the oil every 3-5k miles, then AMS is the way to go.

Question, I have an Acura MDX as well. Still use regular (dino) oil in it. If I want to convert over to Synth. do I have to flush the engine prior to converting? Is it recommended to change over... even after using dino for the last 3 or 4 years?

You should be fine. Just make sire you drain it good. I talked with the Valvoline rep and he said as long as you don't dump a quart of conventional oil in a car filled with Syn. you will be just fine. Then he said even if you did a half and half mixture its not going to hurt anything. I would not suggest it but it would be fine.

This is true which is why I don't buy into the 25k thing with AMSoil. The oil may maintains is lubrication, but the "dirt" that mixes into the oil over time still causes friction. I'm comfortable pushing it to 7500 miles. Recommended interval on my 35 is 5900 miles.

Years back I always heard that Pennzoil was the worst to use. And probably still is the case for their other oils. But Pennzoil Platinum is another story. PP is highly regarded in the industry, I would be very surprised if your varnishing theory applied to it. Now, would I use it in my car? No, but that's more because of my allegiance to Amsoil then my fear of Pennzoil.

I rotate between Amsoil synthetic and Castrol synthetic 5/30 weight oil. As someone mentioned in an earlier post, these synthetics are so light that they provide great performance, that being said, they also burn off more too. In older engines, it's good to check the oil periodically because in my experience light synthetics burn off...

I am on a BMW board also and they all use and suggest Mobil 1 there. Plus it is recommended in my owners manual.

[Tombstone RJ]

Mobil 1 might actually make a lot of sense for a factory oil from the manufacturer. Think about it. As another poster pointed out it's not good to run synthetic oil in the early stages of engine life so mobil 1 allows engine molding for optimization yet provides longer life.

Also, it's been suggested to me that when a car manufacturer recomends a longer time between oil changes it due more to a car leaving a smaller carbon footprint than oil viability. Think about it. There's two conflicting interests when it comes to the modern car: environmental impact vs performance. Oil companies want you to use more oil yet they are forced by enviromentalists to clean up there act so they claim longer viscosity. Yet engine wear and technology has not really changed in the last 20 years or so, so changing your oil less is probably not a good idea. Lighter synthetics offer a great way to make money: they seem more efficient yet more oil is used in burn off.

[Mr. Trout]

I'm not sure synthetic oil can help out my 1996 Buick Regal Custom. Good news is that the chrome grill is on the way from ebay.

cool, I might try that. the car only has 112,000 miles on it and is in pretty good shape still.

[strafen]

Being a car nut myself, I feel I'm somewhat qualified to offer a couple of helpful tips.
1- If your car has high-mileage and leaks a little bit of oil, DO NOT attempt to use synthetic oil. The synthetic oil will find a way to seep thru that "little" leak and make it worse.
2- High-mileage cars tend to have worn-out seals, along with the crankshaft bearings having an increased tolerance. You don't want to use synthetic oils in that case
3- The most popular synthetic oils such as Mobil-1, Valvoline, Penzoil, etc...can be purchased a lot cheaper if you buy by the 4-qrt containers as opposed to buy it by the quart.

Best synthetic oils out there in no particular order:

-Redline
-Mobil-1
-Amsoil
-Royal Purple
-Schaeffer's Synthetic Oil

You for got Castrol and Redline sucks! Your #2 is dead wrong. If you have worn bearing or bad valve guides just move up to a 20-50 or straight 30w. You can then still use syn. and have way better protection without the burn off.

[Cito Pelon]

Nice... can I change over in my MDX and Accord? Both have never had anything other than regular oil.

Well, they say if your engine has an oil leak with dino changing to synth will make it worse, but if your engine is tight you'll be fine. The change is no big deal, I've done it 4 times with used vehicles I bought. I do change the synth again pretty quick after the initial synth change to get all the old dino flushed out.

This is true which is why I don't buy into the 25k thing with AMSoil. The oil may maintains is lubrication, but the "dirt" that mixes into the oil over time still causes friction. I'm comfortable pushing it to 7500 miles. Recommended interval on my 35 is 5900 miles.

Well, I see Amsoil has "severe duty" intervals that are half the miles of "normal duty". I see this 0w-30 (which I think I'll start using) has 35k/17.5k intervals. If I put a whole lot of miles on my vehicles I wouldn't go 35k, but I only put about 8-10k on the vehicles each year, so I just stick to the 1-yr interval.

[Cito Pelon]

I am on a BMW board also and they all use and suggest Mobil 1 there. Plus it is recommended in my owners manual.

Just mentioning as a point of interest, BMW (motorcycles) used to have their own brand of synthetic motor oil, don't know if they still carry it in the BMW motorcycle dealerships.

You for got Castrol and Redline sucks! Your #2 is dead wrong. If you have worn bearing or bad valve guides just move up to a 20-50 or straight 30w. You can then still use syn. and have way better protection without the burn off.I agree. Castrol is quality, no question.
As far as moving up in weight to 20-50 for cars which may have worn out valve guides, journals and bearings, it may be ok, in fact I think it'll be just fine. What you don't want to do is use a heavier synthetic oil on car with present leaks.

Redline, is not an oil I would personally use, and the Pennzoil Platinum has come with a lot of hype into the market, I've used it on my Z06 Corvette and I wasn't too impressed with it.

I went back to Mobil-1. (GM recommended)
Royal Purple is another favorite of mine. The whole line of products for your tranny, differential and stuff like that works real well.
Amsoil, I'm yet to try it, but heard a lot of good things about it.
Shaeffer Synthetic Oil is also an excellent oil with superior protection properties.

I don't get this "burn off" thing about synthetics. I have the same amount of Amsoil in the crankcase after it's been in the engine for a year. Granted, I only put apx 8-10k on my vehicles in a year. But if there's no change on the dipstick after 10k miles, I don't see how 30k miles would make a change on the dipstick. Apparently, there's no burnoff with Amsoil.

And if there was "burn off", I'd see it on the sparkplugs, they'd be fouled. My sparkplugs have always been remarkably clean.

I don't know anything about other synthetics, the only synthetic I've ever used is Amsoil. So maybe the other synthetics have a burn off problem, but I haven't seen it with Amsoil.

With any syn oil the molecules are way smaller and that is why there is the burn off or leaking problem. It runs along the same line as filling your tires with nitrogen instead of oxygen. Nitrogen Molecules are larger so they won't leak out.

The synthetics I use are so light that they do burn off after a while and I'm not sure why there is no indication of fouling or things like that. Car passes emissions just fine too. I just think it's such a light oil that after a while it just tends to basically evaporate due to heat and friction and exit out the exhaust. Either my car is screwed or something is happening to the oil. Every mechanic that has looked at it says it's a great car and there's nothing wrong with it. But, I keep a spare quart of oil in the trunk and check the oil every few weeks, especially after about 3k after the oil change (it gets changed every 5-6k miles). The oil just gradually disappears somewhere and I have to top it off. I don't have to add a lot of oil, but I do have to add some oil after a while.

When syn burns it wont leave a trace on your plugs well sometimes a slight ash but that is it. Note DEQ if your car burns a little oil throw some syn in it and they will never know as long as it is not horrible.

I drive 40,000+ miles a year and have always used conventional oil, and change it every 3000 to 5000 miles. Own a 03 F-150 with 189,000 and and a 98 Dodge Caravan with 206,000. I do not baby either vehicle. Neither vehicle has an engine problem of any sort. So my question is why spend the extra dough unless you going to try to go well beyond 250,000, which very few people ever do?

Haha!! the reason I ask is because those are notorious for tranny failure.

I rather have synthetic oil as a personal choice and when manufacture recommended. If you can religiously change your oil when due and take good care of your car, it really doesn't matter.
One thing for sure, I only use synthetic oil on my high-performance vehicles. I've owned and raced Corvettes and Camaros with modified engines and I would never put conventional oil in those.

Below-zero starts for one thing, Minnesota dude. You will certainly notice the engine cranks over easier, synth oil circulates much faster, gets up to the valve train much faster. Synth just does not thicken up in super-cold weather like dino.

Also, it's been proven absolutely you'll get apx. 2-3% HP increase with synth. That's kind of a big deal.

[Cito Pelon]

G35 Coupe is rear wheel. The Sedan is AWD.

I mentioned I've been out of the market for performance cars for several years, so I checked out Motor Trend to get up to date.

And jeez, these high-end makers like Infiniti, Lexus, BMW, Audi, Acura, Mercedes have really upped the performance dramatically the past few years. And with little if any decrease in MPG/emissions. And kept the prices the same.

Even the full-size sedans are putting up 0-60 times in the 5's. Getting 330-plus HP from 3.5L-3.7L V6's, with 19/25 MPG. Seven and 8-speed autos, 6-speed manuals are the norm.

It's a shame IMO nobody makes a straight-six anymore, even BMW phased out the straight-sixes from what I've seen, maybe I'm wrong.

I do love the straight-six engine. Super-smooth, easy to wrench on, one cylinder head vs. two, one timing chain vs. two. I'm gonna miss my GS300 straight-six when it finally wears out. Hopefully it lasts me another 10 years.

Quoydog, I'm on my third tranny. I picked it up for 5 grand when it had 60,000 on it and had blown one already. Second one at 110,000. The problem seems to be they are prone to overheating. I expect that thing to quit or the front end to fall apart (we have massive pot holes up here) before the engine goes. It's an old peice of crap but everything works and I like not having a payment so I'm gonna see how long it will go.

When it's 40 below, I think it's gonna rattle for a minute no matter what, but you may have a point. Your whole car is over an 1/8 inch shorter in the dead of winter as opposed to summer. There are gaps between your motor's parts until it warms up.

I'm gonna need a new car sooner than later. Might have to try syn this winter in the new one. If it works, it will easily be noticeable. You wouldn't believe the sounds your car makes when it's really cold.

Oil?

I knew I was missing something. No wonder my cars never last more than 20,000 miles.

That's the point, it won't rattle for a minute with synth. I've been in -25 and the Amsoil makes a big difference. Hell, at -10 it's easily noticeable how fast the engine turns over, and particularly how fast the valves quiet down. The starter doesn't strain to get the crankshaft moving, and the oil gets to the valvetrain fast, you don't cringe listening to the valves and lifters go metal on metal rattling for a minute.

I know what you mean about the sounds a car makes when it's really cold. Colorado is nowhere near like Minnesota and the Dakotas, Montana. We know a few things about cold, not like you folks, but similar.

The weather was the toughest change when I moved here. That and not being in Denver when they finally won in '97. I left Colorado with the Jackonsville game still haunting my sleep.

question for those with inifniti's...I'm looking into an 06 m35x. Well, my first choice is an 05 subaru legacy gt limited, but I took that infiniti for a test drive and fell in love. BIG question though, is how it handles in the winter. I have no problems with my current civic, but I'm going to be doing a LOT more winter driving this year, and I've read that the awd in the infiniti puts about %70 of the power to the REAR wheels in speeds below 15mph....Im wondering how they do on inclines, slow traffic, any kind of driving when you're going to need traction at low speeds.

Thanks.

[Flex Gunmetal]

Get some decent tires and you'll be fine.

[Jesus]

#2 You still need to do regular oil changes. Even thought the oil protects better and last way longer you still get the same amount of dirt in it that you would with conventional oil. Dirt works like sandpaper on your cylinder walls and crank bearings.

What is the point of oil filters then? Or better yet why not design a filter to take the oil and filter the sand paper out of it and put it back into the engine??

[Swedish Extrovert]

I like how someone resurrected an old thread about oil, the day before the first game of the season.

G35.

2006 but it only had 8k on it and was flawless with exception of one rim having some sort of black mark on it. The dealership just fixed that yesterday. In the meantime I had a 2010 G37 (convertible). I like my 35 much MUCH more than the 37 convertible. I guess I'm just not that big on convertibles.

As far as the 35... awesome. Love driving to work now ;D and I get there a lot faster now, lol. I'd recommend the car to anyone. I had a 94 Honda Prelude while I was in the Air Force. That car was my favorite car... wish I would have never got rid of it. But the G35 is very similar, reminds me of the Prelude when I wash it... but it has about 100 more HP which makes it a lot more fun. Seriously though, if you're thinking about a new car... find a G35.:yayaya:

Yeah the G35 is nice till you have to fill it up at the pump. Low 20s MPG gets old real fast. I love the Acura TL and Honda Accord V6s (I've got an Accord and the wife has a TL). Well built cars that will last to 200K. Only thing I don't like about the TL is the "Z" rated tires they put on it (unjustified price increase). To say the least I won't be putting the same rated tires on when it's time to replace them.

If you put a tranny cooler on it, it will last twice as long. Heat is a trannys worst enemy. You can pick one up for about 75 bucks

I use Mobil 1 Extended Mileage in my Subaru Turbo.

Only the Extended (higher priced) meets the full synthetic spec, the "Japanese Obsessive" level of synthetic.
