Sea Foam

Hey, i just dumped a can of the stuff into my gas tank. Just waiting for the engine to cool so i can put some into the crank case, then i have to wait 100 miles until i change out the oil and can do the final step....creating huge clouds of smoke

i was just wondering if anyone else has used the product before? any reviews about it?

The reason i decided to use it, is because my truck is only getting about 15.5mpg where i used to get 17-18. Bill would an 87perf tune get slightly better gas mileage as compared to a 93perf tune?
