diff oils blob wrx
 

Time to change my diff and gearbox oils on my blobeye wrx (5 speed TY54)

Is it 75-90 GL5 oil for both rear diff and gearbox/front diff?? No need for any thicker or LSD oils no?
Probs a really stupid question also but the drain and fill up points for the box and front diff are both the same yea? (drain on the same bottom plug, both fill up thru the dipstick tube)

Got some GL4/5 mobil1 mobilube oils at work i was thinking of using...


cheers

Yes oil is ok. Diff has a drain plug and a fill plug so you drain it then replace plug then fill through fill plug till it just comes out. Gearbox has a drain plug nut to fill it just put a length of hose in the dipstick hole with a funnel on it then put in required quantity, on 6 speed is about 3.5 litres but easy to check the level just remove hose and replace dipstick, just use biggest dia hose that fits in as oil is thick and can take a while to drain in, you can get a pressure filler but doesn't take long with a hose and funnel. Easy job really.
