Im going to change my oil in the diff as ive just had plug out & it looks a bit murky,,which oil do I need for a 2005uk sti widetrack.

Andy

 

90ls oil

 

Dipsy is right, the diff needs a SAE90 LSD oil, like the Fuchs Titan Race Gear 90LS, Shell TS90, Castrol Axle Z or Motul 90PA.

Hi,ive seen it on the net that Castrol Universal 75w/90 high load protection will be fine.

Andy.

 

My MY07 Sti Spec C didn't like 75/90 in the rear. It's best with Silkolene BO90LS

 

Yes, that diff needs a LS oil, the Castrol Universal 75w-90 doesn't have LSD additives.

Ok tks for the reply's guys.

Andy.

 

Right then oilman,,which do you recommend for everyday driving,i wont be using it on track.Also how much does the diff hold.?

Andy.

 

I'd probably go for the Fuchs Race Gear 90LS as it's probably the best proven of the ones I mentioned and as it only takes 0.8L.

Did the Castrol universial 75/90 in the rear of the 05 Jdm Sti just seemed louder then changed to silkolene bo90ls like yourself very quiet now.

Rear diff holds more like 1.0 for Sti and 0.8 for wrx a litre that's level with thread on top fill plug hole not through temp plug hole

 

Tks for all the info guys & ive just ordered the silkolene from Opie & also the syringe to make it easier to fill.

Andy.

 

Thanks for the order

 

Just realised i could have got 10% off,,lol,,never mind ill remember next time.

Andy.

 

If you let me have the order number, I'll see what I can do.

Cheers
