I haven't had to use any 100 LL in my Kitfox with 912 ULS yet. I know it's used by many owners, but I've been lucky to have access to a supplier of non-ethanol 91 octane mogas for about $3/gal. I built a 40 gal. tank w/ pump, etc. for the bed of my pickup & it works great, but I realize I'll have to use 100 LL frequently on long cross country trips. My question is, do those of you using it regularly open and clean the oil tank at every oil change? It seems like that would be a real pain. I plan on using Decalin when burning avgas. Is TCP considered any better by anyone on this forum?

Thanks in advance.
