When i check the oil level in my huyndai avante xd 2006 i found the the oil level is down , no smoke or leak from the car .. What's the Problem ?

SOURCE: OIL PRESSUE LOW

At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.

How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.

Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).

If this continues, you may want to have this problem looked at by a professional, as I said.

Your engine might be burning oil, first of all get cylinder compression test done to find out which cylinder is weak, if all cylinders are same or close in value then you might have broblem with the valve guides for leak down.
