Which is best for my truck - Redline gear oil vs Royal Purple gear oil in Toyota sequioa 2008?
I have a Toyota Sequoia 2008 4WD Iam buying your oil 75W85 for differentials (front & rear). Will also buy 75W90 for transfer case.
Do I have to also order and use Red Line Friction Modifier & Break-In Additive 4 oz 80301? Want to do the changing myself but not sure if my truck needs the modifier.
I thought of buying Royal purple 75W-90 for both differential and transfer but they dont have 75w-85 for differentials and rather recommend 75W-90.
I live in an area that temperatures are 35-40 degrees celcius. Will be doing mostly highway and a bit of stop and go traffic driving. Any advise and suggestion on other gear oils?
Regards
