Can my car stop running if the oil light comes on?

the truck is 4 months old. the % of oil and the little wrench light came on this morning while i was driving to work. i added two bottles of oil and now i'm concerned that the car could break down on my way home. i have about 50 miles to drive. the oil is scheduled to be changed tomorrow.Can my car stop running if the oil light comes on?
you should probably add more oil, but maybe get it changedCan my car stop running if the oil light comes on?
i hope you checked the oil level before you added oil. That little wrench is letting you know that service is due not you ran out of oil. Just because you oil life is at 0% you still have oil-just needs to be changed. When I went on a road-trip last year I was 1,000 miles past due when I had my oil changed. No problem-what would you do it you did not have that oil life reminder.
The % oil light on new vehicles tell you how long it is before you need to change the oil, not how much oil is left. You need to check the oil level before you add oil to the engine because you don't want to overfill it. Take it to you dealer or mechanic to have the oil changed and they will reset the light when they do that.
the car will still be able to run for a short time, it will just damage the engine if you continue to drive it with poor oil quality. I know this because my car ran for a long time but it just damaged the engine and quit running, but that took a few weeks... i learned the hard way. But dont worry, you have a while to get it done, its not like as soon as it turn on you cant use it
Read your OWNERS MANUAL, the light is your oil life monitor telling you its time to change oil, NOT ADD.


Make sure the oil change place resets the life monitor.





Should low oil pressure occur you will get a red critical light and a constant audio warning. Low oil pressure can cause the engine to die.
Don't you hate worrying about that?!?!!? That's a horrible feeling...been there many times wondering if you are going to make it. I truly believe that you will make it and be ok especially since you put the new oil in. Good luck sister!





Since the car/truck is so new...it might just be a computer glitch or something. You will be fine.
4 mos old and you have a problem id be at the dealer and not at work... you have a big problem and a oil change will not help that you have a leak no need in doing a oil change if you have to keep adding oil its a big waste of money fix the leak and then have the oil change
Check the oil before you leave to make sure you don't have a huge leak. As long as there is oil, you should be able to make it home.
If your truck is that new, it won't break down. The only thing ignoring the oil light can do is reduce the life of the truck, due to wear and tear.
Learn how to use the dipstick. You can do as much damage with TOO MUCH oil as too Little.
If you added the oil, then you are probably fine for your drive home tonight.
When the oil light comes on, there is not always a problem with the system. Most people confuse it with a bad oil pump. Actually it is an indication that there might be a low pressure situation in the engine's lubrication system.





Here they are, and what to do about them:





1. Low oil level.


This would be the obvious first thing to check. Make sure there are no leaks, too. Especially at a front or rear main oil seal. If oil is coming out of either of these, the PCV system needs to be inspected for clogged hoes, or a sticking closed valve.





2. Engine idle speed not fast enough.


If the engine is turning too slow, so is the oil pump. The oil pump only turns 1/2 the speed of the crankshaft, on most engines. If it is not turning fast enough, the system will never build up enough pressure to work properly. Check the IAC. Disconnect the vacuum hose from the brake booster, and see if the engine runs better and the light goes off.





3. Short in the wiring or guage circuit.


This is a very simple 'system'. There is a sender, one wire, and a guage. To test the system, make sure the wire isn't broken or shorted, by checking for continuity at both ends of the wire, and no continuity from the wire to a ground source (the car body). Continuity to a ground source will indicate a short in the wire. Continuity in the wire only will lead you to test the sender.





4. Faulty oil pressure sender.


Testing the sender is done by removing it from the engine and putting in a mechanical oil pressure guage. This is to test the system for an actual low pressure situation. If there is sufficient oil pressure, then the sender is bad. If there is a low pressure situation in the engine, that's not good.





5. Worn engine bearings and/or oil pump.


If you had a low pressure reading on the guage, then there is something wrong inside the engine. Basically, as long as the engine isn't knocking, ticking, or rattling, changing the oil pump will fix it.





But you have to realize that there are about 40 check valves in the lubrication system, and any one of them could be sticking open. That's why I recommend cleaning the system out. There is a chemical called Rislone. It is an engine lubrication system cleaner. It will break loose the sludge, and help restore oil pressure caused from clogged oil gallery passages.
