I have tried the fitch drop in pellets , designed for motocycles and snow mobiles 2.5 gals though 12 so I got two sets. I have noticed so far a 20 miles per tanksfull increase, but I finally broke down and got the scan gauge so it will probaly increase. Not bad for having some heavy metal and tires. Will post numbers after another tank. I also didnt want to have one topic blank.
What are these pellets?
