So Monolube SHC ( MobilLube SHC 75W90), now called Delvac SHC is the latest gear oil that Porsche has been using in the Cup car boxes.
You can get it here I think: http://www.pfifilter.com/compressoroilpartnumbers.php
But I think for stock gears (non-steel synchros) this appears to be the better choice according to some here: Mobilube PTX 75W-90
Does someone have a source for the PTX- I can't find one.
The place above has a non-Mobil substitute but similar viscosity oils are not created equal ( as a student I worked for 5 summers at a Gulf refinery in a quality control lab testing Gulf products vs competitors- interesting job while it lasted). But I digress.
TIA
