Whats the best gear oil to use in a Ver6 Type R gearbox? Im currently using Millers 75W90 but the gears get abit sticky after 4-5 runs down the drag strip, is it possible to use something like redline shock proof or is that only for ppg gearsets?

 

redline Mt90 on teh gearbox n redline 75w90 on the rear diff

 

I wouldn't personally use the Mt90 as the Subaru box needs a GL5 spec oil and the Mt90 is only a GL4

 

So would the redline heavy weight shockproof stuff be ok? Im looking for the best oil regardless of cost...

 

Castrol Syntrax is the only gear oil i've ever used and ever will use in a scooby.
