Final Gear Case oil part II

kenb · 09-14-2008, 11:35 AM

Been all over looking for gl5 90w (Recommended by manual). None to be found. No info found on what can be used in place of. I would suspect 80-90. I figure I would get everyone's opinion on this. Thanks!

I run Mobil 1 full syn gear oil in a like viscosity 80-90, 85-95.

For the rear diff the manual calls for 75-90W gear oil. In oct. Im switching to that weight in the Mobil-1 synthetic.

Doc you will go a bit more distance per gallon when you do. You may not be able to tell, but you will.

I'm running Amsoil 75-140. It's all I could get and it works OK for me.

KenBob, just read on the back and make sure it says "safe for hypoid". that makes it a gl4/gl5 gear oil.

I located some gl6 90w. owners manual states that gl6 is ok as well. Will be changing the fluid this evening. Most likely go to 80-90 when this is gone after 4 services.

I've been running 75w-90 Mobil-1, but last time I threw in a dollop of Mobil-1 grease to thicken it up just a little.

As my bikes getting some miles on it I will probably switch to 75w-140 next spring.

Thoose CA symbols are greek to me, guess its just a difference in stating oil weights in Canada.
