If an engine has too little oil pressure you might get direct contact between metal parts, which will increase wear considerably. But if you have too much oil pressure you run the risk of blowing out seals, and forcing oil past where it needs to be, which isn't good either. Optima oil pressure would mean having struck the perfect balance between these two.
The oil pressure on the V8 is 75psi at 2,000rpm
If the oil pressure warning light came on, it may mean that you have an oil leak. It can also mean that the sensor is bad.
The oil light is an "oil pressure" indicator. it means you have lost oil pressure or the oil pressure sensor is bad
no oil or low oil pressure
Do you mean an oil pressure gauge? Not tach?
If you mean the oil pressure sender it's right next to the oil filter.
It can mean you have low oil pressure and it can mean that the oil sending unit is bad. Do not ignore this and have this checked out by a trusted mechanic.
It means the oil pressure is low, which could mean oil has leaked out, which could wreck the engine.
Below normal maintenance of an optimal, constant osmotic pressure in the body of a living organism.
It means you have low oil pressure. Low oil pressure means you will destroy the engine if you keep running it with low pressure.
Low oil, low oil pressure, failed oil pressure sensor.
it is the oil pressure sensor. Check your oil level, then test your oil pressure sensor.
