 C14 min. Don't ask me how I know...  Engine sounds great though, bet it would idle a little lower than that... Not to appear pedantic but I think Europe uses a different way to rate octane numbers. IIRC I think 100 octane Europe is equivalent to 107 (ish) Stateside. Still not enough IMHO though. yep! i think 100 octane is around 106/107 US Gasoline .. idle is around 1300 RPM The Euroepan 98/99 octane is about 93 octane US. European gas is rated as RON octane, while US is (RON + MON)/2. Race gas is available, and it must be unleaded, we are using VP MS109 at the track and regular 95 in the street. Was a bit difficult to obtain MS109 in the states... The last barrell I bought cost 26.7$ a gallon. Dirt cheap!

Apologies to the OP for the Hijack, I usually use some 100LL avgas, I always thought this was MON rated only, and I always thought the ratings were the other way round (lower octane in the US). I guess everyday is a schoolday

I have never heard that about leaded or heard anybody EVER get their gasoline tested for lead. Glad I don't live in your state. The Fed EPA are the ones that made that regulation, not the states  I use to use Aviation 100/115 in my M.W. car on the street years ago (pre 1980), lots of people would comment on the sweet exhaust smell even back then All leaded fuel sold today has a distinct different smell from any unleaded pump swill sold today

Raffa...unless you go REALLY conservative on the timing and kill power, you're going to need better fuel. 14:1 needs at least 112 octane IMO. Add nitrous and you'll need more than that.
Like I said earlier, I'd be using VP C12 or C14 on motor only and at least VP C16 on the spray.

I have never heard of anybody getting their fuel checked.
