Triax 75W85 GL-5

[NoClue]

Looks like there's an alternative to redline & oe. 75w85. specs look good. I'll order some and try them out in my front and rear diffs on my 2016

Are you thinking about the transfer case? You can safely run any synthetic 75W-90 in the front and rear diffs. Mobil-1 or whatever is easy to come by

75W LF is the unicorns blood for 2013+ transfer cases though.

no, for my differentials. I've been running 75w90 with my 4.30 gears and harrop E lockers, but I'd like to adhere to the vehicles specified weight gear oil for the front and rear differentials. I run Ravenol 75W in my transfer case

hmmm come to think of it. maybe I should run the gear oil from the vehicles where my differentials are from. 4.7 tundra / 01 100 series

Yeah TBH I would go for a higher viscosity 75W-90 or 75W-110 for shorter gearing (higher ratios). More friction and heat would cause me to step up the higher end viscosity. Nitro recommends 75W-110 for my 4.88s IIRC.

Man, I feel ignorant. I run M1 75w-90 in all three. Do a fluid exchange every spring, so about every 15-20k. Been doing that for the last 80k miles and seems to be a happy truck.

Much debate over on BITOG regarding 75w in Tacoma without clear resolution, of course.

Other than following the manual, is there any empirical evidence of the benefit of running the unicorn tears stuff?

The newer transfer cases used by Toyota / Lexus (is it 2013+?) start have have brass in them but most on the market is GL5 which contains a modifier that attacks brass.

That does remind me to ask do prior year do not have brass syncros?

Therefore the search for a GL4, ideally, single weight 75W began. I just bought Redline MT-LV at $23 a quart, but I needed two incase 1 quart cannot fill to the top.

I'm just talking about front and rear diffs on my 16', not the transfer case

For front and rear diffs, I really like Mobil Delvac 1. Seems to hold up really well, don't get that black burned oil when you drain.

Been using it for a long time in various vehicles that call for GL-5. Transfer case I used Ravenol.

Yes ok you can use this for diffs but what do you like about it over the more commonly available Valvoline synthetic or Mobil 1 etc.
