Underfill, a really big deal.
... however there is a limit for safe overfill.
My wife's coworker got a corporate pool car for short business trip. He was told that this particular car consumes oil a bit so it's advisable to check oil level at gas stops and fill if necessary. So when he stopped for the first fuel fill-up he opened the hood and opened oil fill cap, the only clearly visible cap on the top of the engine.
He didn't see oil level, obviously, so he filled one 1 liter bottle. Yet no oil level in sight, so he bought 5 liter (1.3 gallon) canister and poured all in.
Yet again, so he bought next 5 liter oil .... and again until the oil level was just under the filling cap.
The engine made 200 yards until one piston with connecting rod broke. The remaining rod on crankshaft almost cut the engine apart.
By my deeds I honor him, flat twin.
