I just noticed that Amsoil is now carrying a synthetic metric 15W-50 that meets JASO MA/MA2, which seems perfect for my Ducati with wet clutch pack. Has anyone used this with good results? I've tried Rotella T6 5W-40 in the past, but the clutches would slip too much during WOT shifting (I could even see it in the datalog with RPM spikes after each shift). I ended up using M1 V-Twin 20W-50 for awhile until I found a Castrol Power RS 10W-50 synthetic that didn't have the slippage problem. Just curious if anyone has tried the Amsoil? I normally use a K&N oil filter for my Ducati because it is less expensive than the OEM replacement Ducati oil filter.
