I usually buy my gas from a kum n go or sams club. Since Sams buys fuels from the cheapest bidder at the time and kum n go uses flint hills fuels, they aren't top tier listed. Is there any harm in adding a small amount of techron in each tank of gas to keep things clean lubricated? with the BOGO at AAP and previous use, I like techron alot. Probably make the 20oz bottle last 4 tankfuls. So about 5oz for 17 gallon tank each fill up. (usually put about 12 gallons in each fill up) Thoughts?
