Having done a search I can't seem to find the answer to my query further below.
The owner's manual states the following for a manual box:
"SAE 75 W 90 gear oil, API classification GL 5 (or Mil-L 2105 B)."
This is what my specialist tells me is in the car, but I am experiencing a slight 'crunch' on gearshifts, which is both worrying and less than satisfying. It would also seem to have nothing whatsoever to do with wear on synchros, as the car only has 26k miles on it (!). The problem is present both cold and hot. Sometimes I manage to get a perfect shift, but more often than not... not.
I've read on a US forum that many 993 owners there swear by Red Line 75W90 NS (apparently the NS stands for 'Non-Slip') and that it is the ideally suited to the 993 manual box and will resolve my problem. I'm thinking of buying some to try it out.
Can anyone make any recommendations? Anyone tried the Red Line oil?
