Surprised that this is a high zinc and phosphrous oil , yet the ad says its compatible with production cars . I thought this type of oil was not good for catalytic converters and some sensors . Good price , has there been problems with knock off oil for sale ?

On the bottle is also clearly says it is not Street Legal. Not compatible with cat converters for one thing.

What do you use?

For the street I use Mobil 1 5-30 which is a Dexos equivalent . Lately for racing I have been using Joe Gibbs racing oil , and Wix racing filters . I have not had any oil related problems with either oils . The Mobil 1 oil works fine as a racing oil in my 454 Super Stock engine , but changed to the Joe Gibbs stuff just so my break-in oil was the same brand as my race oil .
