What's the best alternative for nv4500 oil?
 

Stock nv4500 243xxx miles just drained it but can't figure out what oil to get. Cant afford to pay $41 a quart from local stealership. Any suggestions?? Also black oil on bottom inside of case.

They no longer make the Castrol syntorque. I just replaced mine with Mobil Delvac SAE 50wt GL-4. It has made my shifts easier and temps run about the same.

Thanks but. Already ordered some fluid from quad 4x4should be getting here tomorrow can't wait to try it out I've read good things about it!

What fluid did you order?

I believe it's rebottled redline 75w-85 in quads own packaging says it supposed to exceed or meet the specs for the nv4500.

I use Valvoline synchromesh it's GL-4,GL-5 MTF. I have also tried royal purple but didn't like it.

Its usually available at NAPA or those other guys lol.

Yeah the main thing is to make sure its a GL-4 rated gear oil.

Have you ever tried the royal purple stuff? what did you think? its expensive as hell.

I have for engine oil (in my charger and my old Silverado) and currently running it in my rear axle Royal Purple 75W95 with LSD additive. I haven't had any issues out of it and can feel in my head that the vehicles seem a little happier, but that's just more of a subconscious thing.
