Ran 100 octane for the first time. Wow

Local guy with his own personal airport and a dozen or better muscle cars sells 100 for $5.00 a gallon. I run it quite often in my car, ran it all the time in my 347 supercharged mustang. Mustang loved it. I also run my tank dry, and put this in for the winter mo. Got tired of rebuilding carb every spring because of the garbage ethanol gas
