Correct Gear Oil For Gas Gas 280

Featured Replies

Hi there,

From brand new, these have 550ml in the gearbox.

When re-filling, about 50ml or more stays behind, so best to re-fill with 500ml.

If there is too much, it always exits the breather anyway.

Change the oil often as it lubes both main bearings aswell as the clutch and gears, say every 30-40 hours use.

Use only mineral oil, 10 weight or an Auto Transmission Fluid (ATF) rated to Dexron III.

Bye, PeterB.

Hi gasserian,

I agree, forgot it was an 03 model.

400ml is correct for this year.

550ml was spec'd for 04 onwards.

Thanks for correcting this, a senior moment!

Bye, PeterB.

shirty recomends putting 400ml in 05 gassers aswell. although it does say 500ml in the handbook.
