Oil pressure light has almost nothing to do with with the amount of oil in the crankcase. Oil pressure is affected by just a couple things, does the oil pump work, is the pickup screen blocked, have the main and/or rod bearings worn out and does the pressure bypass still work? Rod and main bearings are quite simple, they consist of a hardened crankshaft with carefully turned and polished contact surfaces and rod and main bearings which fit tightly to the crankshaft with no more than two thousandths of an inch clearance when the bearings are new. The contact surface of the bearing is made of a very soft metal called "babbit". Oil pressur keeps the babbit bearing surface from actually coming in contact with the crankshaft surface. If the babbit has worn and the bearing surface has worn to the point that the clearance has significantly increased, the oil will leak past the bearings and the pump will not be able to pump enough oil volume to keep the pressure up. In short, low oil pressure is one of the main indicators that an engine is worn out.
If the engine oil level is at the full mark, the light is not suppose to come on when driving.
If the oil light only comes on when the engine is hot and on idle look at your oil pressure gauge to see if the needle is going down to the low end of the scale if so give it a service and make sure you use 10w 40oil reccomended for frontera and you can put in slick50 or other engine oil additive this will increase your oil pressure and stop the light coming on
Can be the level is low or the sensor is going back.
The warning light can come on when it is time to change the oil. Your oil pressure and oil level can be at recommended levels when the oil needs to be changed.
If it it a change oil light it is telling you it is time to change the oil. There should be another light that is the oil pressure light.
Low oil pressure. Bearing clearences are most likely to large. New or rebuilt engine time!
Low oil or a faulty oil level senser
Low oil pressure of a faulty oil pressure sending unit.
It means you have low oil pressure. Notice the light is red. Red means stop driving the car until this is repaired. Check the oil level and if it is full seek professional help.
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.
light diesel oil
The can with a drip is the oil indicator. If the light comes on, check the oil level (well, you should check the oil at least once a week).
The light means your Oil needs Attention/Inspect oil level.
Put enough in to reach the full mark on the dipstick. If the oil light is on you either have a leak or the engine is burning oil.
Low oil pressure. Such as a bad oil pump.
Your question is too vague. If you are talking about the Change Engine Oil warning, you have to read your owners manual and use the radio volume button to reset the engine oil life after you change your oil. A check oil light could mean you are low on oil. Fill up to 'full' line on dipstick and the light should go out. If you are sure the oil is Full and the light doesn't go off, there must be a sensor that senses the oil level is low.
no oil or low oil pressure
You do not reset an oil light. If the light is on, then you have low oil pressure. It will go out when the oil pressure is sufficent. Check the oil level. If it is full, then you have a problem an should seek professional help. Do not drive this vehicle with the light on.
If the car does not smoke badly this may mean you are using the wrong weight motor oil. Use the proper weight oil that a dealer will recommend.
Defective oil pressure sending unit or the oil pump is weak. Replace the oil pressure sending unit and if the problem persists seek professional help and have an oil pressure test run. Make sure you are not overfilling the crankcase.
check your oil level?
You may need to check the oil, or have the jeep serviced.
needs engine oil ...
The time for your next oil change is coming very near.
The red oil light means you car is low on oil, or there is a problem and should be checked.
