Differential.
Hi, may I know why my differential oil going black when I open up? Can a differential oil going less or mean left 30% inside the differential case after 2 months run ( ~8 times ) if no leaking? Thanks.

if you don't fill the diif to the top you leave air in the diff and it aerate's the oil breaking it down faster....

you hsould fill diffs to just pass the cross bars meaning just above where the two shafts cross and as for the oil you should change it after a few track days it want it to feel the same all the time diff. fluid breaks down and turns the dark color yhour speaking of

oic....just filled over the cross bar...I used to filled almost full of the differential case Ok, I will follow your advise on next service. You mean the diff oil turn to dark colour is normal and it turn to dork due to over used? Please advise. Thanks.

The gears inside the diff are aluminum & rubbing together even in oil will cause slight wear at worst & a continual polishing at best & the tiny alum particles is what turns the oil dark gray.Its normal & a little leaking out past the o-rings during use is normal also for most diffs.

basically yes...and you DO NOT fill the cup right up to to the top...you only go as high as the cross pins as Filling the diff right up will cause inconsistency in the diff itself....air in the diff oil is Nothing you will get away from...they are Not 100% sealed units.
