Question about 2003 Chevrolet Malibu

1 Answer

Oil Pressure low

The last 3 oil changes, my car has required heavier and heavier oil to keep the oil light from coming on... we have tried additives ect, and it was suggested that the sending unit or the oil pump could be defective. Today the took the sending unit off and tested the oil pressure...

At an idle it sits at 7 psi ... @3500 rpm it the pressure is 32psi. I am told this is really low.

What recommendations do you have?

That is low, i recommend you pull the oil pan and check the pump pickup tube screen, it may be the oil pump but i doubt it, my guess is internal engine wear

Why does the oil light come on while idling?


Low oil pressure or defective oil pressure switch/gauge. If vehicle has high mileage you my have an oil pump/main bearing issue causing low pressure. In some cases, using a heavier grade oil may help keep the light out

I have a 1996 ford Taurus 24valve V6 oil is reading full..but oil light keeps coming on and has a slight knocking sound..don't know where to start


First off,when did you last change the oil? Did you change the filter?
Sounds like an oil pressure drop,or a serious engine problem.
If the oil could stand changing,go with a heavier viscosity,like 10W30 or 10W40 if necessary.
ALWAYS change the filter when the oil is changed. don-ohio (:^)

Hi Katherine
when was the last time you had change the engine OIL and FILTER?
what you experience with your car now is due to low oil pressure caused by one of the following.
blocked oil filter or blocked oil suction filter or bad oil pump.
I suggest you start by changing the engine OIL and FILTER.
Good Luck

Low oil pressure light comes on when i stop giving the car gas like when i come to a stop sign or light and every now and again the check engine light comes on. I change the oil to a heavier oil and the...


This may mean engine wear or bad oil pump. I would have the oil pressure tested to see if its a shot some where or if the pressure is really low, this is done by removing the sensor and installing a gauge and driving the car to see if the pressure is low, if the pressure is low then more checking is neede to see why,you may have worn engine bearings or bad oil pump. depending on the mileage it may be smarter to replace the engine, not knowing what internal damage has been done already. good day.

That is the oil pressure gauge not the oil level gauge. Sometimes they can act that way when the oil is thin. When is the last time the oil was changed? Try using a heavier weight oil. When engines wear they require thicker oil. What size engine does you voyager have?

Oil light goes on...had a dry stick 4 1/2 qts put in. no oil on ground. after oil change light went on at 70 miles.. on 15 secs then off for 5 miles then on again 15 secs--- off 4 miles--off 3 miles- off 2...


if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.

My low oil level light comes on


i presume that motor has a few miles on it. possibly the motor is so worn that it can't maintain a decent oil pressure. quick fix is to add heavier oil which hopefully will last for abit. be careful if you are in a cold climate as the thicker oil will make it harder to crank over in the winter.
