Re: 2012 Te 300 transmission oil???
An oil thread
4 strokes dirt bikes mostly have wet clutches and gearboxes in a combined sump, so if it lubes the engine, it also lubes the clutch and gearbox, so fine for 2 stroke clutches and gearboxes too. To save some $ you can use LSD car oil which is also designed for wet clutches and gears and bearings. I use Mobil SHC ID 80w140 synthetic in my IT175 which works fine. 80w90 is fine too. Note that gearbox oil viscosities are different to engine ones, ie I'm lead to believe that 80w140 gear oil is close to 20w60 engine. In fact you can get multi purpose oils mostly intended for agricultural use that are fine in engines, gearboxes and hydraulic systems. I used to use Castrol Agri MP in my old tractor engine, gearbox and hydraulic system, and assorted pumps and generators.
