Very true. I use and sell the Brad Penn oil, it is the best buy in a true racing oil. Very popular with guys running alcohol, because of not "milking up" like many oils do. I've been selling about 10 cases a week, going tomorrow to pick up another 30 cases. I get 40.00 per case if anyone is interested.

The Castrol GTX 10W30 is under 600 ppm of Zinc. The list must be dated by quite some time so I would be careful using its numbers.
