New Quaker State Oil w/ Zinc

@Dannyd
I spent 32 years in the automotive lube business. I just counted eight untrue statements in your two posts. I don't have time to go through them one by one. But that's OK, I'm not going to try to change what you believe, just try to help you get you what you want.

Quaker State has mostly moved on from obsolete products. I wrote to their tech email address when they introduced the All Mileage oil a year and a half ago. I asked the about the zinc and phosphorous content. They didn't reply.

From what you say, this is what you want. Or as close as you're going to get at a reasonable price. Good luck! :thumbsup:
