Help with avgas stoichiometric, facts only please
#21
You are correct as well and I should have mentioned that to help with that I add 2oz of Marvel Mystery oil per every 5 gallons of avgas I put in the car...Havent dried anything up or had any seals leaking from it so far

i have been following this thread and i am wanting to run the same. I have an airport nearby with a cardlock pump the 100ll is 1.9 per litre. I want to run this in my tt vette and bump the timing for more hp. I always worried about fouling the o2's but now i see perhaps it may work. trans an 99 please tell more, about the last year on this stuff what did you do in your tune to compensate over lets say 94 unleaded which i am running now with meth inj adder

The fuel is just like running 116+ race gas, I have 22* of timing in my car at 22# of boost and it never even set off the knock sensor when we were tuning it. We just stopped there as a precaution. Over 94 octane its apples to oranges better and you can remove your meth tank. Its just like tuning your car for race gas but not paying $12+ dollars per gallon for it. I bought a couple 50 gallon barrels and filled them up so im not running back and forth all the time.

also isnt there a whitish ash on the plugs making reading them somewhat different in approach? i ask because i want to check my afr on the plugs once in a while rather than believe my wideband

white ash is common on airplane plugs, 80 octane motors sometimes have the lead form into little *****, very obvious. airplane motors run high power settings continuously, the problems usually arise from power off descents with full rich mixture, cool motor, then full throttle go around cooking mixture on wet plugs, such as a student pilot practicing landings, book procedures are full rich mixture setting up for landing so it is already configured for full power in case of a go around. The other scenario is full rich on ground during run up and taxi, then going full power on takoff and climb on sooty plugs. I personally never noticed lead ***** on anything other than a low compression airplane motor, but its possible. I would guess most problems with either type of fouling would be to not be too rich at idle, full power rich is more obvious, somewhat rich idle is not.

I run this gas in my Camaro & also my Quads. It will leave a slight white deposit on the plug, but tuning/reading them is not a problem.
I have never had a fouling problem, infact the same plug was in my LT250R for 5 years & I never cleaned it... saying a lot for a 2 stroke.
Also I never add any oil to the fuel in my Camaro. It doesn't seem to care.
If I was to add any, I would use 2 stroke racing oil as it is designed to be burned in an engine

That is what I meant, airplanes run excessively rich alot of the time and usually either very cold or very hot. If your not too rich at idle I think you'll be fine, a little rich full power is fine. You won't have the extremes that sometimes cause problems in airplanes.
