Another Seafoam question...if added to the fuel, will it help the truck run more smoothly or is it a waste of money?

 

I wouldn't run it in every tank. The money would be better spent buying gasoline...

 

I have nothing bad to say about seafoam, I run it about twice a year and my truck seems to run better while its in there. Im not sure about its lasting effects, a cleaner carb/dual tank switch valve who knows. I prefer marvel mystery oil as a fuel additive and run it often. Tried both in the crank case, didnt like the results.
