The price difference is a non-issue to me... I just want the best product for my vehicles, and I'm sure many people feel the same way.
I would especially like to hear from our members who swear by conventional oil. If conventional and synthetic were the same price, would you still choose conventional?
Synthetic is better, no question. Molecules are closer in size that causes it to be more "slippery," more additives, more tolerant to extreme conditions, keeps your engine cleaner, won't sludge as easily, etc. If synthetic and conventional were the same price, I would choose synthetic. If synthetic was more expensive, I would choose synthetic. The point is that conventional is a great oil too so these days it doesn't really matter which one you use, but you can't argue it's better.
