I've got a 2000 4Runner 3.4 V6 (5VZ-FE) I've had for a year, 180k mi...I've rotated through two oils.
I drive 18-20k mi/yr, mostly highway. Live in SC. 5-6k mi OCI, using oversized OEM filters (YZZD3).
I had been using Mobil 1 HM 5w30 but the engine seemed a little noisy. Switched over to Rotella T6 to quiet it down and have noticed a slight decrease in mileage (22 mixed --> 20 mixed), which makes some difference as much as I drive.
I've got 2qts Rotella left from my last change that I'll probably just stick with, but I could mix (if that's ok)--I'm torn on a few possibilities after this OCI.
Thinking of swapping over to Valvoline Maxlife 10w30 (either full synth or blend, thinking blend to save $$), PYB 10w30, or maybe trying Mobil 1 10w30 or 0w30 AFE.
Thoughts? I know with my shorter OCIs synthetic probably doesn't matter. I also know I'm probably overthinking it--but that's probably why we're all here. I just want to maximize the life of the truck that I love.
Oh, and here's an old UOA:
