The (lower) MMC sump isn´t baffled inside due to clearance issues towards the crankshaft - which leads to problems when cornerinh hard continually.
Especially on tracks which bends tend to go just to one side (and are taken enthusiastically) this causes major issues (which was the case in the incident Heinz mentioned).

Overfilling the sump is critical, due to the crankshaft diving through the oil on a permanent(-ish) basis which might lead to "foaming up" the engine oil...

I went the way to install an entire Accusump system 2 years ago & haven´t had any issues since.

Only my personal experiences hide
