80W GL -4 HYPOID GEAR OIL 4 Years, 1 Month ago  
Where unders God's Heaven do you get to buy this 80W GL -4 HYPOID GEAR OIL ?

I ve been to the dealer and they gave me an oil which says
YAMALUBE LUBRICANT
FRICTION MODIFIED SHAFT DRIVE GEAR OIL
SAE 80W-90 API SERVICE GL 4 ,GL 5

caution :this product was formulated for yamaha atv and golf cart differentials which incorporate a friction clutch or brake inside the differential .it extends the noise fee and vibration free opeartion of the
clutch/brake far beyond a typical differential .it contains a superior antiwear and anti scoring additive for protecting gear teeth and bearings from the rigors of touch running over steep terrain .a dispersant inhibitor system helps maintain the pliable nature of the seals ,preventing leaks .

this product may also be used in yamaha differentials which do nota contain an integral friction brake or clutch and which specify API GL4 or GL5 gear oil .


can i use this for the roadstar ?

appreciate your advice!

The closest thing that I found that is GL4 and close to the weight they recommend is Nissan Manual Trans oil in 75W85. Part# is 999MP-MTF00P at any Nissan dealer. I've had it in mine for the last 5000 miles.

There are also some synthetics available that will cover the specs Yammi recommends.

The stuff they gave you should also work from the info you gave off the bottle.

These should both work... (Feel free to correct me if I'm wrong.)

http://www.amsoil.com/storefront/agl.aspx

http://www.redlineoil.com/product.aspx?pid=46&pcid=7

Edit: The main criteria is that it is 75/80-90W and GL-4 or GL-5. Make sure that it will work with hypoid gears, and you can't really go wrong IMHO.

It takes more love to share the saddle than it does to share the bed.

Re:80W GL -4 HYPOID GEAR OIL 4 Years, 1 Month ago  
FYI,a fellow RSC memeber posted here a while back that he contacted Yamaha technical staff at jheadquarters and asked if it was in fact ok to run the lube with GL hi pressure additives and they said it was fine,not an issue at all so your good to go.

I an running Mobil 1 80w-90 LS syn lube in the transfewrr box on my 06 silverado & so far so good with 5k+ miles on that lube.

If your still worried you could try Royal Purple's new Max Gear 80w-90 lube.


RP's max gear lube has the latest generation of GL5 hi pressure additives that aren't as harsh/corrossive as the older older generation GL5 additives couls be in some situations like for ex the yellow metals used for syncros in older generation manual trans like GM's Muncie 4spd used.

As far as i can tell the transfer case on our R*'s doesn't have any yellow metal type bushings etc in it so if that's the case even the older generation GL5 lube with the more corrossive hi pressure additives would not be an issue.

If you must have GL4 only lube you can order Staylube's GL4 conventional Hypoid 80w-90 gear lube from your local NAPA.

Heat bike/transfer box & oil up ,drain the trasfer case,then refill with approx .45-.50qt (1/2 qt lube)and your good to go.
