is it GL5? if so i dont see a problem running it

 

Well on the back it says it meets API GL-4 and GL-5, Military MIL-L-2105E and Mack GO-G & GO-H specifications. So in there it says GL-5. Is this what you are talking about?

 

Sounds like the right one to me.

 

That will be fine.

 

will work great.

 

Hypoid gears are what are in the rear differentials of cars and trucks. So yes, what you have is what you need.

 

Awesome. Thanks guys.

 

You're welcome.

 

Does anyone know if they make a Full Synthetic Hypoid GL-5? Mobil One maybe?

 

Mobil 1 Synthetic Gear Lube LS 75W-140

 

There are a lot of synthetic gear oil out there. Redline, Royal Purple, Mobil 1.

 

I did a little research last night and decided on Mobile One 75w 90, also GL-5 and Hypoid full synthetic, changed it earlier this evening, good to go!!

 

amsoil also runs a synthetic gear oil. i believe its 75w-90. not positive though. i lucked out and got 5 quarts free! so im good to go for a while. i honestly dont see the point in synthetic gear oil. i dont understand why one wold worry about the oil being synthetic or conventional cause all its doing is lubricating gears lol

 

I will never use synthetics in my crank case with clutches but for a rear differential, absolutely, first off, it reduces friction by 50% or more, also, it lasts eons longer then conventional motor oil not breaking down and does not deteriorate rubber seals like regular mineral oil. It stays the same viscosity whether its 30 degrees out side or 90 degrees, meaning it circulates immediately, Rear diff will last virtually forever with this stuff in it, provided you don't get water in it swampin your quad all the time. Its actually pretty amazing stuff, i've been running Castrol Syntec in my automobiles since it first came out, I think around 6 or 7 years ago. A lot of research has been done on synthetics, most people have no idea how advanced it is.

 

interesting....sounds good to me
