As I mentioned earlier, we do not use any Mobil 1 products and have not for several years. We do, however, continue to be able to test various M1 grades as cars come in for service with M1 oils in them. Unfortunately, I do not like the results. Repeated testing has demonstrated that the product is no longer what it once was, and if anything continues to go in the wrong direction.

That said, M1 10W-40 is one of their better remaining products; but it can still be out performed by a considerable margin by other products like Syntec, and usually for less money as well.

I have no experience with the other oil..................
