best oil for sti6 gearbox and diff?
 

I was wondering what oil people would recommend for the above gearbox as Im having trouble with a few sticky gearchanges.

Also for the rear diff as I may aswell do it all at once.

Cheers

Castrol syntrax. :thumb:
Works wonders. :D

would you use this oil in the rear diff? if so where would i get it from and how much would i need?

thanks

Same in rear diff. Oilman on here sells the stuff, think its around £45 for 5L. 4L for the box and 1L for the diff. :thumb:
You can also get the stuff from oilman on ebay (opie oils) or halfrauds if you're lucky. :D

redline mt90 for the tranny and redline heavy duty shockproof for the rear diff

can any of these be brought from halfords?

halfrauds sell castrol syntrax or use some redline heavyshock proof

Do any of them reduce the 5th gear crunch when pushing hard?
