Just got off the phone with them. They recommended the TR1R 10w30 for both Vixen and Gladys. Summit sells a case of 12 for like 139, which ain't terrible. I may go ahead and do that next payday. He said their PPM of ZDDP was 1800.

That’s a great oil and the price isn’t a ball busting 22 bucks a quart.

EDIT: 23.50 per quart for the oil I use. dammit up another buck and a half a quart.
