A lower octane gas woudn't cause it to blow blue smoke, more like it needs an engine job. There is oil getting into the combustion chamber, could be valve guides, valve seats, piston rings worn.

If car has hole in over drive will it cause smoke come from tailpipe?


Besides being a poorly worded question...
We can try...
White smoke from the tail pipe could be a blown head gasket as coolant enters your cylinders and is exhausted.

"hole in overdrive" needs clarified...

My 92 ford is using excessive gas and has a bad gas smell with alot of smoke coming from tailpipe after i add gas


If the smoke comming from the tail pipe is black your running rich. If thats the case the entire fuel system has to be ckecked out. Injectors could be leaking, a bad pressure regulator,stuck return line ,a coolant temp sensor could be telling the ECU that the engines cold give her more gas. I don't recommend doing fuel service unless your qualified to do so for the obvious reasons.
If the smoke coming out of the tail is grayish you have a bad head gasket. If the smoke coming out of the tail is blue you have engine oil getting into the combustion chamber. keep me posted

Car is hard to start, keeps stalling, white smoke coming out of tail pipe


It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

I have a 96 eclipse 2.0 with 150 thousand miles there is blue smoke coming out of the tail pipe smells like chemicals.


Blue Smoke: Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.
How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder. I that doesn't work then i would get with a mechanic and have it leak tested for possible piston ring replacement.

My truck blows white smoke


Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
