Sliter litt med å forklare den der egentlig, hehe. Men fant en som kan vise litt frem, står på engelsk men.
Sitat:
Be careful not to overfill your car's crankcase with oil. If you put in too much oil, the engine's crankshaft can actually come in contact with the oil. And because the crankshaft is turning at several thousand revolutions per minute, it can quickly whip your oil into a froth — like the steamed milk that sits on the top of a cappuccino. Why is that bad? Well, the oil pump can't pump froth very well, and as a result, it can't get oil to the parts of the engine that need lubrication. The result ... a hefty boat payment to your mechanic.
