If it is burning oil it is burning oil. This means your rings have gone bad. Vehicle will still run if it isn't too bad. As for the engine dying I would guess this is caused by another problem. Any check engine light on? If so get it scanned and see what the code is. Good Luck
have it checked for oil leaks, if there is no oil leaks or small leaks that won`t justify the amount of oil your losing then you engine is burning the oil. it could be stuck oil rings. there is chemicals that you can add to the oil to see if they will free up and stop burning oil. just because you don`t see a lot of smoke out the tailpipe doesn`t mean its not burning oil. another thing to check is the PCV valve as if it isn`t working properly can cause oil burning as well.
there`s only 2 ways to lose oil. one is a leak somewhere from the motor the other is the motor is burning oil. just because you don`t see smoke doesn`t mean its not burning oil. you don`t say how much oil your losing between oil changes. if its only about 1/1.5 litres between oil changes then this is a normal lose which means its burning slightly.
Blue smoke (how many miles on engine, 50k or 500K???????
to some this means, burning oil, others steam
it that blue smoke lingers a long time that is oil burning
and smells just like oil burning.
and means 2 things,
1: engine burns oil.
2: if car had autotmatic trans the vacuum modulator love fail
and suck ATF fluid to the intake plenum and burn it, and bingo burning oil like mad.
3: PCV valve packed solid,and forces engine to leak oil or burn oil. or both. this is a 50k miles service point, skipping this?
4: gas in the oil making it thin and not sneaks past valve stems.
does oil change cure this.>?
now engines.
worn out engines smoke. (burn oil)
as do bad valve guides and seals.
and bad piston rings.
100 years same story, and miles matter. History on engine too.
matters.
the problem may be that the car is burning oil. if its oil the smoke from the back of the car should be black, white then thats your fuel burning, a combination of both would mean that your car needs a tune up and an oil change, jiffy lube express should be able to get that done for a decent price
the ones that are white.. means your burning coolant so that side of the engine has a leaking head gasket.. as for the 4 black ones.. that most likely means your burning oil, and the black smoke indicates burning oil as well.. that could be bad piston rings, valve seals, bad pcv valve... it could be all those things....
there are a few reasons for the engine to smoke. first determine the color of the smoke, white smoke means its burning water...possible bad head gasket or cracked block or cylinder heads. If the smoke is black...means the fuel mixture is to rich, getting to much fuel. If the color is blueish...it is burning oil, meaning the oil rings are worn, and or the valve seals are worn as well. if it smokes when you first start it, and then stops after a few minutes, once the engine is warmed up...probably bad valve seals. if it continues to smoke it is more likely the oil rings. Valve seals being cheaper and easier to repair, where as the oil rings means the motor needs to be rebuilt or replaced.
well if it is white smoke and smells a little fishy, that is anti-freeze burning up so your head gasket mostlikely needs to be replace. but if it is a blueish white smoke that is oil being burn and that mean that you need to change your oil. if you have been changing you oil normally and it is giving you that then that means your pistion rings are worren. if you don't want to replace them you could put a heavier oil in like if normally you use 10w-30 you could put in 20w-50 in and that should help. worren pistion rings allow excess oil to get into the pistion chamber and that is why it burns it up, This should also be noticed by you oil level dropping faster then normal too.
it all depends on what color the smoke is. if it is black then that means that the engine is burning oil. if it is white then that means that is burning coolant. if it is burning oil then it needs new piston rings. if it is burning coolant then it can either be a blown head gasket or it is leaking through a coolant passageway in the engine itself and would need a new or rebuilt unit.
