White smoke from the tail pipe is moisture/water turned to steam.It comes from the air drawn into the engine and/or coolant in the engine.If you see excessive white smoke and your coolant level is dropping,you are most likely steaming coolant.Oil burning usually comes out as blue smoke.
just about everyone does with either an old car or a new car with high mileage.how excessive? is oil consumption.well first thing is to check for oil leaks either underneath the motor or any oil lines feed into the motor .any major leaks would be pretty noticeable.if none are present then one would assume that your motor is burning the oil through the exhaust system .check to see what color smoke is coming threw the tail pipe.blue or black smoke indicates oil burning white will indicate engine coolant burning.in any case some color smoke is normal just depends on how much.so lets say your exhaust smoke is normal still could be burning oil just not a noticeable amount.on average you shouldnt have to add anymore than 2 quarts a month or every 1000 miles .depending on your driving conditions if you are having to add more than this there would be a leak some where or heavy color smoke.keep up on oil changes and always add lucas oil usually 1 quart its alot thicker than conventional oil so it reduces engine wear and will handle any small leaks in the engine components like the pistons and rings.if problem still present get to a dealer or certified mechanic as soon as possible good luck.
WHITE smoke? Or BLUE smoke? White smoke is usually caused by burning antifreeze (possible blown head gasket). Engine oil burning causes a bluish colored smoke.
Changing the oil two months ago means absolutely nothing to me. I have customers that travel 6000 miles or more in a month. Oil consumption is measured in volume over miles, not volume over months. It is normal for most 4 cylinder engines to use a little less than 1/2 quart in 1000 miles (even more than that for 6 cylinder and 8 cylinder engines).
is it a gas engine or a diesel? it could mean two different things depending on the fuel type. black smoke in a diesel is either an air of a fuel problem. in a gas truck there should never be black smoke. it may be a dark blue smoke which is burning oil.
Is it really burning it, or just losing it? If you have blue smoke coming out your tail pipe, and oily black spark plugs, there's really not a whole lot you can do about it short of a rebuild of your engine.
It really sounds like a rear main seal leak, or a faulty oil filter.
If it's only on cold start ups, then it's ok. You should be glad for it's a sign of engine in top condition. If the white smoke doesn't stop even when running then you may have a worn out piston rings which will surely require replacement to resolve the problem.
It surely is burning oil that's why it emits white smoke.
Hope this helps and thank you for using FixYa! Have a good one!
didn t say what color smoke --if you start up on cold or damp days and get a small white or steam looking discharge from tail pipe than your burning out/off the moisture that has accumulated in the exhaust system when all moisture gone smoke gone ---white alot- billowy-and doesnt stop burning coolant -water/anti-freeze-leak in coolant or the famous blown head gasket ----black smoke and not a diesel carbon build up and or need tuneup---blue smoke burning oil something in engine is damaged and allowing oil into cylinder and is being burnt
White smoke is caused by coolant or water
coming out the tail pipe. There is a
chance that the white smoke was caused by
water splashing up from a puddle onto the
exhaust pipe. Keep an eye on the
coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....
