does anyone use 100LL av gas ?
Used to run 1/4 avgas to regular unleaded in the 440 cross ram 67 Charger I had. No problems what so ever and ran the best with it. 100 LL still has 5 times the amount of lead that regular leaded fuel used to have, so it will accumulate on plugs. Stay's fresh much longer and if there is a fuel leak the blue dye helps in tracing it
