I have slowed down to running between 60-65 mph on the interstate and so far, I can tell a little bit of a change in the mileage. I'm just under half a tank and so far I have gone over 150 miles on this tank.
I do have a question though. When I fill up, I usually go to Kroger and recently I have been putting the Kroger Additech in with my fuel. I haven't really noticed a change since I started putting it in. Am I just spending needless money?
