White smoke coming from exhaust, smells like gas

It could be doing its job, sounds like what you put in tank is problem. Oil change would not cause that. I would not worry unless it keeps going after fuels runs down.

check the compression in all cellenders you might have a blown head gasket, burning smell might be the gas in blown cillender not igniting

white smoke is usaully coolant, could be head gaskets

you have either a blown head gasket or cracked head. The white smoke is coolant passing through the engine and exhaust. The gas smell is from compression leaking past the gasket or head, pushing fuel vapor into the air.

Sounds like it is burning coolant, possible blown head gasket or cracked head or intake leak.

If too much coolant enters the cylinder it will stop the engine from running.

White smoke is usually a sign of head gasket problems.Gas smell could be the unburnt fuel from the cylinder head which is the source of the problem.

a tune up will not cure smoke, sounds like u may need a head gasket replaced.

check fuses

Yes, unfortunately it sounds like you have a blown head gasket. You can check your oil dipstick to see if there is any water in the oil and also check your coolant to see if there is any oil in the coolant. If so then you have a blown head gasket. The problem can only be resolved by having the heads machined and replacing the gaskets.
