Don't get wrong, I have heard nothing but great things about their fuel additives. Even if I had heard of their oil additives, it still doesn't mean the car companies want them used. Who knows, maybe McGeorge is using some low grade motor oil and have to add this oil additive. Of course charging th customer for it.
