Need to help my STI box last a lot longer, what is the best synthetic oil to use? The car gets a pasting on starts with 5000 rpm and - dump - the - clutch methods. Any ideas on what is best (for the diffs too)

Silkolene SYN 5.............already running in numerous gearsets rated for over 450 ibs ft torque........

 

the Neo stuff is apparently very good

 

I tried Silkolene full synth. in the gearbox of my 99my and got crunching when changing from 4th to 5th at above 4k Needless to say I changed it quick to Castrol Syntrax for an instant cure! I guess the Silkolene was too slippery? (It now resides in the gearbox of the wifes Primera!)

millers full synth 75w90 or they do a 80w140 for super protection............most of the synthetic oils should do the job though to be fair.......

I use Castrol Syntrax with no problems cause I can't find Redline products here but many people swears on Redline lightweight shockproof!
