Looking here, the 320 spec seems to be .05 mm max for the mains and .067 mm for the big ends. Did I miss something ?
(Minimums for each is a lot less).
No I didn't and don't know the specs I was using the .06 as example just to say that is why we don't use 30w oil as most people did 25 to 30 years ago.
