Hi every one there is no doubt that fuel is main part of every vehicle i have a neon which i suspected it had a problem with fuel pressure. i put in lucas into the gas tank. now the car is smoking and a bad odor is coming out the exhaust. is that bad? will the lucas desolve or waste or would it jus sit in the tank forever?

 

I guess smoke is unusual for exhaust... you might want to take it to your dealer for further details
