Valvoline is just as good as the others. Used Valvoline conventional and maxlife in the past but my vehicles prefer Pennzoil products purely based on my "ear test." I feel Maxlife ATF is one of the best ATFs in the market.

I use valvoline and napa(nearly the same thing) quite a bit. Its my favorite because of its patriotic American colors lol.Also its served me well.
The bad rap it gets on here is clearly all based on peoples intrepretation of its voas. Even though it preforms excellent and is quite shear resistant, too many people just cant get past it not having tons of certain additives and it being formulated with sodium instead. Well apparently its a great formulation that works well and they must use a quality base oil.
Valvoline proves that tbn retention is not equal for all oils and that valvoline dosent need a high starting tbn
Drop by Yellow Bullet or Chevelles.com and look at one of my preferred oil polls. Valvoline VR-1 by a 2:1 margin over the next most popular brand (Mobil1). Maxlife is usually 3rd or 4th above all the rest
I'd call that love
Valvoline's add-pak is great in flat tappet motors. And we're talking really stout motors running in the 10's and 9's with full steel bodies at 125~140 in the quarter with 8K readlines in BIG motors (500 cubes +). Their track record for durable engines is there for anyone to look at.
There are certainly other good oils, but these guys (mostly) who have built $10K~$25K engines do not guess on oil, and most run Valvoline VR-1
I've seen MaxLife take my parents' '97 Suburban from 170,000 to 400,000 (and counting!) with less than 1/2 qt. consumption between 3,000-mi. changes and strong compression readings at 340,000, and cut consumption in a Buick V-6, Chrysler V-6, and a Jeep 2.5-4 by 30-50% - that's all the proof I need!
