Maybe I've been out of it for too long, maybe not. I would appreciate your comments and opinions.
I have been using M1 which I thought they used a PAQ for its base stock. The 10W-40 with 1000 ppm ZDDP. Now I've read M1 has gone the way of Castrol and is using highly refined oil as its base stock. True or not true, how do we know for sure? Then I read that most engine damage occurs at start up and 10W is too thick even in warm Atlanta. Apparently this weight does not properly lubricate at start up. A 0W was advised as an appropriate weight. I decided to try a 0W-40 M1. I couldn't find it at Wal-Mart.
Then I spotted Penzoil Platinum Synthetic - European Formula 5W-40. It states on the bottle that it uses a full synthetic base stock along with superior anti wear additives. Are we talking ZPPD here or what? I have not ever seen this oil before. Is this a new product from Penzoil? Thought I'd give it a try and see what kind of oil pressure I get at start up. Maybe even send it out for an analysis. What do you all think?
