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?
Question, have you replaced your tranny on that caravan yet?
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.
