I use Driven products exclusively... That's not a recommendation, I don't give a damn what you use unless you have my engine. Here if someone requests some other oil, I send them to another facility where the person at the controls cares less about what they create. I'll use nothing else.

Having developed these oils alongside Lake Speed Jr. I know what has gone into them, and how we are constantly working on the better formula.

I do the development for my engine program, and Gibbs will make anything we want in return for our assistance.

That said, I have NEVER seen a cat on a German car fail due to zinc and phosphorus content elevations... We have ran zinc as high as 2700 ppm and still no failures.

Zinc seems to only kill Asian car cats.
