Modern Gearbox oils

[Grumpy225]

Dopeshots,
Maxima MTL 85 is a GL3 Gear Oil, which means it has mild EP additives. These additives offer more protection to mating parts by creating a chemical barrier between Gears etc. As a comparison Rock Oil ST90 is a GL1 oil and as such as no additives other than anti-foam etc. Just to be clear, EP additives do not create Clutch slip. Another GL3 Gear Oil is Castrol's ST90.
And just to finish with a little advertising, Scooterotica, Chiselspeed and MB endorse and sell Maxima Oils.

I agree, been using MTL 85wt for years now. It's cheap, works great, no clutch or shift problems and can pick it up locally.

The multi grade gear oil will be ok as long as it is GL1,2 or 3 anything above will probably attack silver/bronze parts in your gearbox.

Fek, just checked what I put in my TS1 gearbox, Halfords Motorcycle 80/85 GL4......might account for some of the slipping

Used MTL-E 85 wt in my TS1 in the States. Excellent gear oil.

Jaso MA spec will work with the clutch, if anything 10w/30 is a little light, would be better if it were 10w/40, but I'm sure it will be ok, it's roughly equivalent to an 80 weight gear oil which Vespa's use.

Just fitted a Saigon scooters 5 plate clutch , what oil would be best to use with this as the plates are different from usual lammy ones?
