Just curious about the oil warranty found on labels. For example Amsoil warranties that their oil can be in your engine for 15,000 miles.
Let's say you ran Amsoil for 15,000 miles. During the change you noticed that Amsoil was really in bad shape. You decided to fill this time with a different brand.
Then your engine fails @ 15,000.0001 miles because previous Amsoil was ran for 15,000 miles, (which cause lack of lubrication, worn engine parts etc.) will Amsoil warranty hold?
