Not trying to start anything, but years ago I was the store manager of a NAPA Auto Parts store. When working there a Seafoam rep came to show us their product, I was amazed at what I saw that day. The guy took a can of seafoam and used my car as the demo, I had a 95 Trans Am, with a ZZ502 create motor in it, the motor had been worked over by Fulton Racing here in Spartanburg and roughly produced 900 H.P. with the dual 300 shot of NOS, 700 H.P. at the rear wheels. And close to 750 ft-lbs of torque. I had well over 20,000 in the motor and NOS system. But this Rep put a can of seafoam in my tank, he sprayed it straight into the air intake and he took a vacuum line loose and put the hose into a can, now i raced this car on the drag strip but it was still street legal barely, but I ran 110 octane sometimes mixed with 97 octane. But when my car started smoking like and old coal locomotive I started to freak out thinking something was bad wrong, but it really was just the carbon and crap burning out the engine. My car ran smoother, it was just a hair quieter as far as any engine noise I had noticed, which with the exhaust system it was very hard to hear the engine noise except very high RPM's. Now I know its claimed to only be for 2 cycle engines but that truly is not the case, it may have been years ago, but look at their product lines, they have fuel injection cleaners which I've never personally seen a fuel injected weed eater before but I'm sure someone makes one, fuel system cleaners for gas and diesel engines never seen a 2 cycle diesel either, my suggestion would be pick up a can of whatever you feel will work best for your needs after doing research on different products, or as one person posted they tried 3 different ones, one did nothing, one made a difference and the other I think did too can't remember now. Me, i have used seafoam in both my Bigdogs and they both are running at the moment, knock on wood. lol. But go to seafoamsales.com and read their reviews, their question and answer page.
