When the engine oil icon becomes illuminated, drivers should pull over immediately and check the oil level on the dipstick. Your vehicle may be leaking engine oil.
If the oil level is at or below the ADD line, oil should be added. If no oil can be seen on the dipstick, the engine may be leaking oil or the problem may rest with a bad oil pump, a defective oil pressure sending unit, or the oil pressure gauge or warning light switch.
The engine should be visually inspected for signs of leaks at the valve cover, oil pan, timing cover gaskets, or the front and rear crankshaft oil seals. Otherwise, the engine may be burning oil due to worn piston rings, valve guides, or valve guide seals.
TIP: Older engines are susceptible to burning oil because of worn piston rings, valve guides, or valve guide seals.
