Hi,

going to change the oils on the car,just wondering how much Gearbox oil I need? I have an 03 STi (UK car) I'm going with millers I think 75/90,should i use the standard stuff or go with the new Racing NANO oil?

also the manual suggests the same oil goes in the diff is that correct?

thanks,anything i should know before changing the gearbox and diff oils?

thanks,

 

Take out the filler plug on the diff before you drain it just in case it's seized. Be a bit of a bugger if you drain it and can't refill it!
I use a large syringe (50ml) and a 10mm pipe to refill the diff due to the lack of room to swing a bottle about.

Refill the gearbox via the dipstick tube. I use a funnel with a long skinny tube, do it slowly though because it over flows the funnel!!

I have a 94 WRX, unsure if amount of oil is the same but i use the same in both.
3.5l in the box, 0.8l in the diff.

 

What tool do you use to get the draining plug (square shape indent) out of the rear diff??

thanks

 

thanks Mike,

half inch ratchet I think... can anybody confirm the amount I need?

 

If you're using the Millers CRX 75w-90, you can use it in the gearbox and diff and 5L will cover both. The gearbox takes 4.1L and the diff 0.8L.

75w-90 Gear oil

Cheers

great,thankyou

 

If you haven't got a sump plug tool then a 1/2 inch ratchet does the job.

 

do the non DCCD car's still have a L.S.D? if so is the millers CRX 75/90 the right oil?

thanks,

 

For the rear LSD cars, use the Millers CRX 75w-90NT LS or as always in Subaru diffs, the Silkolene Syn 5

 

I'm not even sure if the 03 STi's have an LSD? can anybody confirm..it's a UK car.

 

anybody?

thanks,
