Why would the engine on a new car completely run out of oil in only few weeks?

Answer 1

When the PCV valve is not working correctly it will suck the oil from the engine into the intake manifold and burn it. All fluids should be checked daily this way if fluid is low and no obvious leaks you can get it looked at before loosing an engine

AnswerCars are allowed to burn oil. I wouldn't be concerned at all if my fleet vehicles were burning a quart every week. If you just checked the oil dipstick and its dry, it could be only one quart low, not bone dry. If you love your car you will check its oil every week, AT LEAST. It could be a leak. Check the oil pan drain plug for proper torque. You may want to check for sludge near the top of the oil pan under the car- then you will need to change out the oil pan gasket, and re torque the oil pan bolts. Then theres the oil seal in the side of the engine- that should be completely clean. If your changing the oil- you would want to see that the oil filter is intact and the oil filter gasket was present. Filters can break open easily on the highway if you get a rock or shrapnel under the chassis. New engines will burn oil because of newly honed cyliders/ bored holes. The used oil will have some more metals in there, but that's good when its new because your cyls have to break themselves in. New stuff just has to wear itself in to become a lubricated machine. AnswerSince this is a new car under warranty, you need to take that question up with the dealership. They're going to look at the number of miles you've driven, as well as check a number of things on the vehicle. For example, they'll look for leaks, look for engine oil in the engine coolant (radiator), and hook up the diagostic computer to check for any telltale error codes that may be set. If the oil usage is normal, they'll tell you, and if there's a problem, it's their job to fix it.

Haha you are screwed! Brand new car and you didn't check the oil?
