Just rebuilt a p2 VSE1M engine 0047810
Casings will only take 150ml of engine oil. The filling hole is lower than other engines I have in the garage. Anyone seen this before?

I always lift the back leveling the engine better and pass the 250ml mark. Never had issues with overflowing…

Has anyone tried 400ml, to see the difference in a real world situation (with the gearbox spinning at a faster rate than turning by hand)? Can the added inertia of a higher level of oil affect performance? Or make the oil start gushing out of the breather? I'm guessing the oil filler hole is at that level for other reasons than just oil economy.... (not talking about the OP's situation, which does seem unusual)

Check this out. The instructions for the VMC 10 Molle clutch. It says 400-500 ml of oil.

Yikes!! Anything to do with the material of the plates? It seems cork plates are more forgiving than the new technical stuff. But that usually affects to type of oil usable, not the quantity...

An old mechanic told me years ago the best quantity was level with the filler hole. Something to do with too much oil negatively affecting the free movement of parts inside. The way he explained it seemed to make sense. I guess I'll try tipping the scoot to the left next time; see if that makes a noticeable difference.

I never overfilled it. Presumably once the oil start to drip from the filling hole that is already plenty, at least that is how I understood.
