what causes low oil pressure
Bad oil pump bypass valve, worn engine bearings, missing oil galley plugs. etc.
Defective oil pressure sender or gauge can indicate low pressure when the pressure is normal.
So verify by checking the oil pressure with a mechanical gauge.
Ok Oil pressure is about 25 to 30 give gas over 40 steady 25 r up just bought it 95000
That sounds ok, try replacing the oil pressure sending unit, and give it an oil & filter change if it is close to being due.
