2005 mazda tribute, ran very low on oil, constanly putting oil in it, not buring no leaks, oil light came on , pulled over, no oil in engine, put oil in engine, rattling noise in engine, I did put Lucas oil in the engine, that did make noise quieter, but still there , Does the engine need to be replaced or is it a lifter? There is only 80,000 km on the engine, oil is very clean, motor is very new looking no oil spills on engine

SOURCE: engine seized no oil did not get check oil or check engine light

The oil pressure warning light only comes on when oil pressure drops below 4psi at this moment there is no oil in the engine most often it does not get to this point because oil, water etc is checked every week. It could be your engine was using oil which would point to an engine fault.

SOURCE: rattle when starting up

ITS POSSABLE THAT THE WRONG OIL IS IN THE ENGINE OR IT NEEDS A SERVICE? MAYBY ITS LOW ON OIL

Just took my car to the shop for the same appearent reason me also thinking it may be lifters. My mechanic said it spounds like a worn wrist pin ...... bad news for you if this is the case .......recomendations rebuild the engine or buy a new or remanufactured one. if the wrist pin lets go then you could throw a rod. If you must drive the car please be gentle

SOURCE: 2005 mazda 3 2.3l that is burning oil (no leaks)

possibly the pcv but check if your cars exhaust smoke is blueish or white in color if it does and your car doesnt have an oil leak then sure its burning engine oil along with fuel, the piston rings is defective, since you replaced engine oil the additive that the owner has put with the oil to prevent blowby is gone thats why it starts burning oil.....
