Oil fill light

Hi Wendy, hope I am wrong but it sounds like a cracked head or blown head gasket.
If the engine hasn't been started in a couple hours pull the engine oil dipstick and look at the oil level. If the oil level is over the full mark you likely have water in the bottom of the oil pan. Milky/semi-white oil on the dipstick would indicate the same. If the oil looks good and at or below the full level look in the water overflow for the radiator. Any sign of oil or milky looking foam is an indication of oil in the water from cracked head/block or blown head gasket. If both the water and oil look good start the engine, let it warm up and look to see if you have water coming out of the exhaust pipe. It is normal to see some water come out of the exhaust after starting a cold engine due to condensation in the muffler and catalytic converter but a healthy engine should have only a slight amount of water vapor coming out of the exhaust. Anything more would indicate a cracked head/block or blown head gasket.

This is the "Low Oil Pressure Warning" light. It is RED for a reason! When this light (or any RED warning light for that matter) comes on, pull over and shut the engine OFF at once. Allowing the engine to run with insufficient oil pressure can cause a catastrophic failure in mere seconds. Such a failure can cost thousands of dollars to repair.
This warning is most often the result of a very low oil level as indicated when checking on the oil dipstick. The engine oil level should be maintained as close to the "full" mark as possible - without exceeding it. Oil should never be allowed to drop below the "low" mark on the dipstick. If the oil level is shown to be between full and low, the light is probably coming on as a result of a faulty oil pump (the oil level should be checked with the vehicle parked on level ground, with the engine OFF). A faulty oil pump is unable to pump the oil with enough pressure to reach all the moving parts of the engine that require lubrication. Without proper lubrication, connected moving parts heat up, expand and seize. Moving parts are expected to move - not be prevented from moving.
If your engine shut down, it may be the result of some of the internal parts seizing. Hopefully, this is not the case. Check the oil level and top off as needed to bring the level up and attempt to start the engine and have the vehicle checked by a trusted mechanic.
Good luck!

replace oil level sensor

check oil level on dipstick under hood with engine off. oil level will show on dipstick when removed.add oil as needed,DO NOT OVERFILL 1/4 inch low can be 1/4 quart low on oil. add oil as needed oil light comes on when low on oil,,,,,,worst case is no oil pressure,,,if oil is full,,DO NOT START AS YOU MAY HAVE A BAD OIL PUMP in which case if you run engine,,it blows.. if you have a oil light,check oil 1st,than if it's full,check oil sending unit,if good then move on to oil pump,,,,thank you for choosing fixya.comk

No if you have filled the engine with (at least 5L) of oil it HAS to be showing a little on the dipstick. The indicator can come on with low oil pressure or sometimes they have a float in the oil pan indicating the vehicle is actually low on oil. I'm not sure where you put the oil into the engine or if the oil plug and filter were installed correctly, but the dipstick ONLY indicates the amount of oil actually in the oil pan. If its not on the dipstick then its not in the oil pan.

OIL LEVEL CHECK Every time you stop for fuel, check the engine oil as follows:

1. Park the vehicle on level ground.
2. When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
3. Open the hood and inspect the level of the engine oil tank. The fluid level on the tank should read between FULL or F and LOW or L.
4. If the level is below the LOW or L line, remove the cap and add enough engine oil to reach the FULL or F line. Fig. 1: Fill the engine oil tank located under the hood first
   
5. Install the oil cap and hand tighten.
6. After filling the oil tank, remove the engine access hole cover on the drivers side. Fig. 2: Make sure the oil tank is to the F mark Fig. 3: The oil dipstick is located under the driver's side engine access hole cover Fig. 4: Place your finger through the hole and pull straight up to remove
   
7. Remove the engine oil dipstick and wipe it clean.
8. Reinsert the dipstick, push it in as far as it will go, the pull it out and look at the level on the end.
9. If necessary, insert more oil through the oil filler cap next to the dipstick, this will completely top off the system. Fig. 5: The oil dipstick has two markings for level check Fig. 6: To fill the crankcase, remove the engine oil filler cap

My truck does the same thing, pressure never drops to 0 but drops low, replaced the oil pressure sensor and same thing happened. My oil is always black and has a lot of metal in it, next time you change your oil, pour a quart of transmission fluid into the oil and let it run for 10 minutes or so, this should thin out the oil and possibly unclog some of the ports that may be gummed up. What could have happened with the dipstick is that the old oil was too nasty to drain all the way, with the fresh oil it could have thinned out and raised the level, try the transmission fluid trick and see what happens, next possibility is to have the engine scoped to see whats going on inside

First make sure your drain plug and filter are installed and tight, then add 2 liters of oil and check to see if there is any showing on the dipstick. Add one liter at a time and recheck the dipstick. Bring the level up to the full mark on the dipstick. Now start the engine and observe the oil light(turn off) or pressure gauge(pressure goes up) then turn off engine. If neither happens after about 10 seconds, shut off engine and check for leaks or other malfunctions. If all is O.K. then recheck oil level on dipstick. It should be somewhere between the upper and lower level, usually indicated by crosshatch marking. Add oil to bring oil level to full mark. Small amount at a time. Most small vehicles only take about 3.5 to 4 liters.

Check the engine oil level every time you fill the gas tank. The car should be on level ground when checking the oil.

1. Turn the car off and wait several minutes.
2. Locate the engine oil dipstick and withdraw it from the tube.
3. Wipe the dipstick with a clean rag and reinsert it in the dipstick tube.
4. Remove the dipstick again, hold the dipstick horizontally and observe the level of the oil.

Fig. 2: Observe the oil level on the dipstick and add oil if it is low

1. The oil level should be at the FULL mark on the dipstick.
2. If the level is at or near the LOW mark, replace the dipstick and add fresh oil to bring the level up to the FULL mark. Do not overfill.
3. Recheck the oil level and close the hood.

Good luck, and remember rated this help!!!
