I've been re-thinking all of my fluids lately. I recently switched from years of using Mobil 1 oil to Pennzoil Ultra after a couple of UOAs pointed to my engine liking it better. Now I'm re-thinking my ATF. I've got 130K miles on my Toyota Tacoma and I've been doing ATF changes (just draining ~ 4 quarts with the AT drain plug) every 30K miles. I've been using Mobil 1 ATF from the beginning. I've had no issues and everything is working well. I was at the auto parts store and noticed that Valvoline Maxlife is about half the price of Mobil 1 and I'd been reading a lot of good reviews of this Maxlife product. Basically, I don't care that much about price (although there IS a significant difference). I mainly want to use what will keep my tranny happy for the longest. Obviously, no one on here can give a recommendation with 100% certainty, but I'm looking for opinions. Does anyone have a 2002 Toyota Tacoma (or similar year) that is using either product with success long-term? I'm talking about in the neighborhood of 100K miles. Like I said, I've been using M1 for over 100K miles myself, so I guess I have a good handle on that. I'm really curious about long-term usage of Maxlife in a Toyota transmission. Thanks!
