Do I have a potential problem? nope. Ford went to an on/off type fake gauge because of complaining just like in this situation about low oil idle pressures and needle variation. To an extent, oil pressure is required for the oil to be able to reach all components of the engine, however if the oil pressure reading is outside of this range, it is usually considered too high or too low. My boat currently runs 25-30 while idle but will sometimes drop to 20 when picking up a skier. As a result, multi-grade engine oils came out, to even the playing field.

An oil pressure instrument that operates with a load- or speed-dependent threshold requires an oil pressure sensor rather than a switch. I recent had a oil filter fail, with an AC/Delco filter, and was having an apparent restrict flow with a oil pressure running 28 to 30 PSI. High volume oil pumps are quite unnecessary. That is the reason why oil pressure can decrease below 50 and 40 psi. You may observe that the low oil pressure warning light comes on and off while you’re driving. My question has to do with what kind of oil pressure I should be running.
