Re: C-16 fuel in a stocker
Kyle,
My 1961 172 Cessna with the 0-300 Continental engine was designed for 85 octane fuel. The only aircraft fuel now available is 100LL, A 100 Octane low lead. It burns so slow and cool that it makes these engines varnish up & stick exhaust valves. I got an FAA STC to use automotive fuel. I have found that a 50/50 mix of non Ethanol 87 octane pump gas and 100 LL works best. Climb out power is better & cruse is more economical. Just like you gave your scooter what it wanted/was happy with, I gave my 0-300 air plane engine what made it happy. It had too much " Octane" with 100LL. A few years ago when we were VP dealers they had 54 different fuel blends available. That should really confuse things..lol Way to many variables and combinations to just guess what works best.
