So I just picked up a 2016 Toyota Sequoia 4x4 with 197K miles (previous owner apparently drove a lot)
we will be doing occasional heavy towing, I move a lot for work and tow a large enclosed trailer. the rest of the time its a grocery getter and kid hauler and the wife's primary vehicle.
Given the miles I want to baseline all the fluids to fresh synthetic,
issue is the diffs and transfer case
front and rear diffs call for a total of 3.81 qts of 75w-85 GL-5
the transfer case call for 1.43qt of 75w-90 GL-5
I am annoyed by the slightly different viscosity, part of me just wants to stock one fluid,
we are in Florida and I would think I could get away with 75w-90 in all 3 compartments with probably some small imperceptible decrease in fuel efficiency being the worst effect, but I am open to ideas
I am looking at red-line, I have used it in the past long term with good results, their 75w-90 is 16 cst at 100c and the 75w-85 is 12 cst at 100c, 40c is 112cst vs 68cst
thoughts? stock two diffrent fluids? run all 90wt? run all 85wt
