2010 Toyota RAV4 sport V6 4WD/AWD
I notice on the front and rear differentials it states that they take 85w90. Currently I have both running on Wolfs head 80w90 high performance gear oil cause it was cheap through my work. I bought some liquid moly 85w90 since it was the only gear oil I could find with that weight, is there much of a difference? I live in the Virginia Beach area so it really doesn’t get all that cold here although I have noticed it doesn’t perform its best when I try to drive without letting the coolant temp at least hit the bottom mark on the gauge and MPG is really bad until it warms up. MPG is huge for me since I have the 2gr-fe and only seem to average 18mpg, which gas prices rn I’m sure you can see why I want to get better gas mileage if possible. I have a custom catback with duel 2.25 tailpipes. Although I haven’t really changed up my driving style since the exhaust upgrades.
