I want to replace my diff fluid front & back. Is there anybody running redline fluid? If so what kind/weights? Reason being is I get redline cheeper and I am tryin to save a few bucks. If redlines no good, ill prob. end up running amsoil. Im open to all suggestions, fire away...

 

Try Royal Purple. 75-140 wt.

 

I run Amsoil, but I'm a bit biased, as I sell it. I also think its a much better fluid than the others. If you are going to run synthetic, my recommendation is Amsoil 75w110 severe gear... Its compatible with limited slips, and open differentials.

I run Redline and I think it's the best. Changed mine at 15k now have 66k and everything is still clean. About every 10k I check and clean the small amount of mud off the magnets. I use the 75-90 gear oil in the diffs, C+ATF in the transfer case and MTL in 6 speed. I think its the best bang for your buck. I plan to change it all again somewhere between 75 and 100k and probably never change it again. I also use Redline 10w40 motor oil in my wifes toyota, daughters Kia and my Yamaha Rhino.

 

I would definitely go with the Redline...Amsoil and Royal Purple are great too.

 

Redline, Royal Purple & Amsoil are great... I use Redline (140W rear diff) since it's relatively cheap and readily available.

 

Schaeffers 75/140 here.

 

Does anybody run cenpeco? If so what weight? My neighbor sells it and said it is the best stuff on the market. I was ran the fuel treatment and it worked ok.

 

Red Line makes the best gear oil out there.

 

redline in mine... 85-250 severe gear... flows better and has less frictin than others do w/ 80-90!

 

Ditto on the Schaeffers
