If Buster prefers PP, that's good enough for me.
You can get Edge quite cheaply with the MIR and the ten dollar off coupon from AA.
You could have gotten PP even more cheaply, three oil changes worth at $1.00/qt using the Wally gift card rebate for two, and the SOPUS actual $ rebate for the third.
Locally, Meijer also clearanced out PP at as little as $1.49/qt.
I now have a nice sub-stash of PP, as well as 5 qts of Edge.
Now, I like Syntec 0W-30, the kind labeled "Made in Germany" on the back.
It is just another Syntec come sale or rebate time at AZ or PB, the only US sources for this oil.
I have 10 qts of it left and will use it in the Subaru, as it is what is in there now, and my slightly informed impression is that the Subies really need something a little heavier than a 5w30 starburst SM.
Any of these oils will serve you well if drained at reasonable intervals.
Based upon at least one UOA here, Edge is not an extended drain oil. PP is not promoted as such. Syntec 0w30 GC is a real long drain oil.
