Transmission oil 1976 WR 360

Hi all, what transmission oil should I use in my 1976 WR 360? Synthetic or mineral, grade, quantity? Thanks, Charlie

i like to stick with a full synthetic unless you have an application that requires you dont..the manual calls for 20w motor oil so i use amsoil 10w30 motorcycle oil. rotella white and blue jug diesel oil is actually jaso rated for wet clutches and many have reported long engine and tranny life in bikes on and off road it so thats probably a good option as well...many here have also had good luck with mobil one if you use a non friction modified weight..

Silkolene medium weight gear oil.

cafe husky is the ONLY place i have seen oil threads take place where people just share what they know and no one gets mad..its pretty amazing really.

Briggs and Stratton 20 wt oil is good and usually easy to find in mower/small engine shops

ATF type F, any brand.

ATF fluid for me.

Type F ATF has gotten my 73 125WR over 10k hard miles on the original clutch and transmission.
There might be better oils now...but I'll stick with what has worked for me.
I also use it in primary chain/clutch cases of vintage Brit bikes.

Hi Guys,

Oil technology has changed a lot in the years since the bike was made, I would suggest any of the oils that have been

recommended will be fine, I would choose the cheapest and change after every ride.

Frequent oil changes are the key!

If you would like my recommendation a base mineral oil suited for petrol and light diesels, 15w-30.

Just make sure it is suitable for wet clutches.

Racing you could use ATF and change after every race meet.

Oil is relatively cheap, parts are expensive!

Cheers, DaveM.

Mobil 0W40 - similar to using ATF

I'm not too sure about that. The first time I even mentioned 0W40, I was sure they were going to Tar & Feather me, maybe even burn me at the stake.

+1 on ATF Type F and change often.

atf f is for sure excellent for clutch feel and shifting...i worry tho if its as good as a heavier weight at protecting gears and such...stays clean looking too

"...i worry tho if its as good as a heavier weight at protecting gears and such"
mate.... a 7 Litre V8 pushes pretty hard on those gears in an auto and the turbo series of autos are pretty bullet proof with ATF...don't think a little alloy piston is gunna frighten its shear capacity too much

youre probably right, many car and truck manual transmissions use atf as well.
