not likely--
What color smoke??--blue=oil burning,white=anti-freeze or tranny fluid(bad modulator valve diaphram)--I doubt if its the gas,unless you put 2 stoke mix for a chain saw or something in it accidently...I have stored trucks and let them sit over a year with the same fuel,they didnt run that great when awakened until fresh gas was added,but no smoking--maybe your rings got stuck while sitting or some surface rust formed on the cylinder walls during storage...
We fixed a car at my friends shop that had a junk motor,we put a boneyard motor in it--when we started it,it smoked like a chimmney!--we called the boneyard and thanked them for sending us a motor worse than the junker we pulled out--the guy got very defensive and angry,and said"I personally inspected that engine when the car came in,it was A-1,no way its junk--he came to the shop too see for himself--we let it run for at least a half hour,smoking like hell--he kept insisting the motor wasnt bad,and after awhile,the smoke started to subside,we assumed it was running out of oil to burn!--but we checked it,and it was still full!(and clean too,no prestone in the oil)--we later realized when the old motor was pulled,a quart or so of antifreeze had spilled out of the heater hoses,and poured directly into the exhaust pipe,it took that long to burn off inside the converter and muffler!!
I have seen gas make white smoke on EFI vehicles that arent running right though,so it could be bad gas--only way to check is to run it off a gas can of fresh gas,and see what happens..
PAULY383k10, that sounds like it might be it.dew on the outside,chances are there is dew in the tank. my garage even sweats now that i insulated the walls. if it warms up quick all metal objects are covered with dew,
