Isn't the general thinking that too much oil in the crankcase can cause the crankshaft to splash through it, resulting in frothing, and the oil pump doesn't work so well with air in it?

Might be more applicable to engines that have a smaller oil capacity to start with, compared to BMW engines.

With too low an oil level, you at least get some clues, such as the oil light taking a little longer to go off on startup, or slightly hotter running, before the oil warning light comes on.

With too much oil, is the absence of any obvious tip offs good enough to say there are no undesirable things going on?
