Transfer case oil.

My manual for my 2017 calls for GL5 75wt oil. Anyone ever use a 75-85 synthetic? I also want to use synthetic in front and rear diffs.

 

What I use.

I grab the quart bags so its easy to fill. No need to go find my pump.

 

75w90 gear oil is commonly used for xfer case fluid. Many dealers use this also.

I agree with above post on bags. So much easier than pumping the fluid.

 

Redline MTLV for me.

 

Oil fight!

Any off the shelf 75/90 will do just fine.

 

I use Mobil 1 synthetic. Any quality gear oil should work.

 

Should keep track of names that say any quality oil is fine for the gears but raise holy hell if OEM engine oil isn't used.

 

JUST REMEMBER.....if you have a Harley YOU HAVE TO USE THEIR OIL!

 

I wouldnt do it. Use the recommended lube. I use Redline MT-LV.

Its Low sulfur formula lacks the reactive sulfurs found in most GL-5 oils that cause damage and is safe for brass synchronizers

 

I used redline MTL

 

Funny I was at the dealer today rechecking an alignment. I asked my service advisor how much to change the oil for the front diff, as I was already there. He quoted me almost $400! He said I had to change the front, middle and rear diffs. Lol! I was like, "what did I miss?"

Well they did have the "center diff lock" in the 4th gen.

 

yikes!

 

Redline MT-LV is what I use.
