DO NOT USE AIRCRAFT FUEL. I only use it on auto that take lead. Avgas rating is 100LL (LOW LEAD) which is only low lead to aircraft but is much more than the old leaded fuel. It will trash your O2 sensors and plug your cats. I would be using it daily if I could. It is easy for me to get since I work on aircraft. You can use Jet A mixed with diesel. My next truck will be a diesel.
