Even I often tell people not to bother with synthetic if they are not interested in synthetic or they do not plan on owning the car or truck for 10 or more years! I am the first to admit that if the person is only going to own a vechile for 2-5 years then trade in then synthetic oil makes no sense at all. Todays modern SM oils have the best base stock's of any API aproved dino oils in history because of the requirment for cleanliness and volitility. I would like to see these numbers geta bit tighter so that all group-I basestock was elimanated from the oils completly before I jump on the dino band wagon though. In fact when Chevron Supreme moved to all Goup-II and II+ I was useing it in some of my other vechiles and it was turningin great UOA. I just wish I knew what products had nothing lower then GII in them.
Their is one exception if someone was going to use bypass filtration and push the limits of the oils then synthetic makes sense as well from a cost stanpoint. I seem to remember some Chevy with 409,000 miles on it that had only had something like 4 oil changes with Amsoil and the engine was clean inside and running well with good compression etc....
