I'm using 0W-40 Rotella T6 and it works OK. I had 5W-40 T6 before and can't tell any difference.
I doubt any oil will get rid of the typical clutch drag on a wet clutch. The only time I get clutch noise is if I'm in a gear too high for the conditions.
Well this one has more drag than I'm used to. The 5-40 is what my sons SV uses and I'll switch the bmw over. As well as the fleet. Which will make things easier.
