However, my car has two front mounted oil tanks and one has a dip stick whereas the tank on the left hand side of it has a sight glass. Why does it have two ways of measuring and which one is used when?

I took the photographs when the engine was cold and notice that the oil level is a bit above a (homemade?) notch on the dipstick. The oil level on the sight glass was just above the bottom of the glass. I've not tried checking again with the oil up to temperature and idling, but if I was to hazard a guess I'd say that the notch on the dipstick is an approximate cold level and the sight glass is used to measure oil level when hot and idling.

Does anyone have any suggestions? If have to take an interest in this sooner or later but have started looking at it now because I have just received the car back from a specialist and it now has very high oil pressure.
