Royal Purple High Zinc Synthetic Oil on sale at the base PX
« on: March 11, 2016, 10:45:35 PM »
Royal Purple oil is on sale at the base PX by where I live.  It's the high zinc synthetic stuff made for classic cars with flat tappet cams.  Price is $5.30 a quart.  Should I be buying a bunch of this?  My engine has less than 200 miles on it since the rebuild last summer.

Wow thats about half of what I just paid at NAPA. I think I'd be buying a case or two. But I'm not a fan of running full synthetic oil in a new motor.
