my car has been sitting for like 2 months with the same fuel in the gas tank and what i wanted to now is that does the fuel get old will my car smoke with that old fuel or act diffrent and its only like a gallon left inside gas tank

 

Two months, No! If it was like 4-5 months then maybe.

Shouldn't do much at all unless you got some water in there then you would have rough running and a little smoke.

Go to the gas station and get yourself a gallon to mix it up with and you will be fine.

 

i wonder if thats the reason my car is smoking isnt there a way to find out if the head is messed up by taking off the oil cap while car is on anybody
