Hi Tom, Yes, I fly almost totally using 100LL aviation fuel. The only downside (other than cost of course) is that the spark plugs appear to be come fouled more quickly than using automotive gasoline. Where as folks using automotive gasoline get close to 100Hrs before change is needed, my average time on a set of spark plug is closer to 35 - 30 hours. IT appears that the lead in the fuel shrouds the ceramic center and the build up eventually affects the spark plug. I believe it causes current leakage and therefore hinders the voltage potential build up necessary to cause a spark.

Subject: [FlyRotary] Leaded av fuel & Alcor TCP

Hi Rotorheads,

Does anyone regularly fly their rotary on aviation fuel? Or has anyone heard of the Alcor TCP fuel additive 'that helps lead scavenging'? Does it seem necessary for av-gas? I picked that up from this AvWeb news article: http://www.avweb.com/newswire/10_34a/briefs/187941-1.html
