I had a wideband in the car and checked plugs many times..... I previously ran cam 2 50/50 with pump gas.... and actually the mixture was richer with the 100ll than the cam 2 mix, but I got that straightened out, I also used my buddies snap on bore scope to look at pistons and valves and no odd build up or abundance of carbon, all looked well..... except for the fuel line haha, I might replace it with aluminum line.... or the PTFE braided hose
