Hi everybody, I'm would like to know what is the best gearbox oil to put in my 05 280 gasser.Some of my mates are using ATF but i'm not sure what is best.I used to use Motul 10/30 in my Scorpa sy would this suit the Gasser or is it to thick.THANKS.

ATF is fine.

ATF is fine.

ATF yes and preferrable "Dexron III" I think.

If not ATF you should use 10/40 pure mineral oil. Not synthetic.

500 ml is fine, any extra may exit out the breather pipe, not that it causes a problem though.
