    did you ever do a test to see if ethanol gas will unfreeze a fuel line that has ice in it? its alcohol so would ethanol work better than isopropyl gas line antifreeze? or will ethanol gasoline keep water from freezing in your gas line? just an idea

      For something you may not know, high octane fuel does NOT mean more power. It's actually less power. High octane fuel is for high compression engines to prevent pre ignition. Put high octane in a car that calls for 87 octane, and you'll have a car that runs bad.

        Lead is better if you have an older engine with non-hardened valve seats.

        Air fuel ratio corrected av gas has more energy content than v10 however ave gas is designed for high compression engines and is poorly suited for engines designed to run on v10 pump gas engines.

        Hey project farm does mixing synthetic and non synthetic oils , because of a leaking engine, and bringing oil pressure to running level lubricate less than either alone. In other words is mixing oil brands and synthetic not synthetic (mostly)dangerous.

        I am watching your fantastic videos. Looks like head cylinder and components cleaning abilities depend on temperature. I think the higher temperature in lowest RPM is the key in 80%.

        There both gasoline and the difference in how they run has nothing to do with there being lead in it more likely the lack of alcohol in the fuel the more alcohol the richer you have to run the engine.

        100LL is formulated for high altitudes at a pretty steady rpm for long periods of time. You gain nothing by running it in ground based engines and it's still toxic.

        WARNING: Seriously important advice on wearing nitrile, latex or any stretchable gloves while using a drill press or any high torque drill or wire wheel - DON'T DO IT! - Even a tap of a stretchable glove on a spinning wheel, especially one with cutting edges (drill bit) or scraping edges (wire wheel) can suck your gloved hand around that spinning surface and break your hand or fingers and even remove them. The action is so fast you won't have the time to pull back. The more durable the glove the less likely it will tear off your hand and the more likely it will draw your fingers around the spinning drill bit. Especially the durable black nitrile "mechanics" gloves.

          Back in the late 80s I worked on the civilian side of a military airbase, we had 3 fuel trucks with 100LL. Every morning we had to drain 5 gallons of fuel out of each tanker, (helped reduce any water build up) back then we dumped it in what basically was just a hole in the ground.
          I used to run my old 69 truck on it, and an old 68 harley. Never did run them on it straight, but at about 75% 100LL- 25% cheapest unleaded I could find.

            @Carson Prince I think I flooded the engine with too much oil. Don't know how to resolve the issue.

            It could be an issue of lubrication if you are finding metal shavings in the oil. Check for any leaks or low oil first. How old is the oil too?

          The aviation "low lead" fuel is by no means low in lead content. It was labelled as low lead fuel when it was compared to the original higher lead content of aviation fuel. The orginal aviation fuel had a higher lead content then today's leaded aviation gasoline does.

            The reason the AvGas runs fat is because it is formulated molecularly to run above 3500 rpm and to run at altitude where the atmosphere is much less dense. To make a good comparison at sea level you would have to re-calibrate the A/F ratio to compensate for the atmospheric pressure increase. Also, the 100LL still has MUCH more lead in it than automobile fuel EVER had.
            Once the engine is recalibrated for the AvGas, you'd also need to run a plug about 2 or 3 heat ranges hotter than OEM spec. The reason I know this is because I used to run AvGas in my 12:1 SCR hot rod engine and did extensive research and testing to get the A/F ratios dialed in for max power and streetability. The testing you did was interesting, just not complete. Love your channel!

              I don't think you've done anything with a gasifier yet? (heat wood under low oxygen conditions to produce a combustible wood gas). Gasifier engines and conversions have been around for about 100 years.

              Thought leaded fuels were banned... I wouldn't say lead in the atmosphere is worth any boost in performance of any sort

                And to think this was the norm in gasoline from the 20s to the 80s. Lead is harmful. Plus watch some of the documentaries on leaded gas that they were using ethanol to control knocking but there was no money in it so that is why lead was in gas so money could be made off of it. Money more important than people.

                  Been using avgas for years. It’s not designed to run in these engines. O2 levels are not meant for using at ground level. You need to mix it with high octane pump gas. Preferably ethanol free. That’s the magic sauce.ive had good luck at a 50/50 mix. Thanks for the great content.

                    Neat video, but I **think the advantage of being able to use leaded avgas is that it has a lower propensity to detonation. In race cars this allows you to advance the timing and/or turn up the boost beyond what unleaded lower octane fuels can handle. If you just swap fuels, like shown in this video, you're likely to not see very much difference/benefit other than the lead deposits from the avgas.

                    This video did make me consider how do airplanes that use this fuel deal with the "extra" deposits that are constantly being put into the engine.
