I have a VW that requires a special VW501 Spec oil. The only way to determine if the oil meets those specs is to read the small print on the back of Name Brand oil containers. Can I sue any oil company for NOT putting on their container that the oil won't meet my needs? GM has similar specs, you have to research to ensure you are using the proper oils and it is not up to the store to warn you other than in labeling, which was clearly done.

In addition - before anyone could win a lawsuit, they would have to prove they suffered damages. Which is damn near impossible to due when attempting to blame your lubricant as the cause of such damages.
