Thank You so much for a great product.

Thank You so much for a great product. Your fuel additive I started using back in 2003 in my Crotch Rocket. Was having a fuel issue and your product took care of it overnight. The real story is I have a friend who parked their cay 96 chevy in the barn in 2007 and didn't try starting it till 13 mo's later it ran like crap a bad miss and wouldn't idle. We did put a fuel stabilizer in with the fuel before we parked it. So I put your fuel additive in the tank and let it run forr about 5 min and moving the car around to mix well. Then waited a week and started it again. You'd never known it had been sitting for a year the miss was gone and was running fine. So we put around 8 oz's in fuel tank and sloshed it around. that was 2008. Yesterday my friend & myself were getting it ready to put it back on the road. It didn't start at first but on the fourth try it fired up. It ran a little rough for the first 3 min or so then gave it a little gas revving it up to 2500 RPM a few times and that seemed to clear its throat. It'll take new tires, brakes fuel filter and oil change along with other things for it to be safe on the road. I never would have guessed your product is that good. You have a customer for life with my friend & myself.

Thank you again,
Kenneth Honeycutt
