I was wondering if anybody ever uses the fuel additives that are now all over the market. There are many different kinds for diesel and gasoline engines, whether it is trucks, boats, tractors, ATVs, even lawnmowers. I have had some luck from using the Lucas oil treatment on a full tank, I noticed a gas mileage increase, more of a longer break between gas station stops lol. I did however achieve around 100 miles by just burning up one quarter of a tank. Anyone else that has used these treatments or has found the magical cure to ethanol feel free to share!!!!!!
