Went shopping last week and found several places that carry Pennzoil and Quaker-State fully synthetic oils close or under $4 a quart.
Mobil 1 regular price has gone to $4.69 a quart in my area.

Has anybody using them done oil analysis for any of these brands?

Anybody has the data sheets (specs) for them (for some reason they are not posted in the web, as Mobil 1 does)? How they compare to Mobil 1?

I did check the oil spreadsheet but none of the 5gen Max are using them.

 

i use penzoil synthetic all the time no prob with it...
