    Can you somehow make an engine run on water like back in the 1900’s.

    I've been running a 50/50 Ratio of Aviation Fuel & Unleaded Fuel In My 1980 GMC 350 V8 1/2 Ton P/U...No Cat..No Computer..RUNS GREAT AND SOUNDS GREAT WITH DUAL EXHAUSTED

      I can’t believe how much lead ended up in the combustion chamber and on the plug, running it for such a short time.

      I’m puzzled. How can a turbine engine function for such long durations on jet fuel if lead deposits that heavily? A lack of a pressurized combustion chamber?

        Thank you! Running under load and at higher RPM likely helps.

      Will a diesel engine run on used motor oil. Or how much used motor oil can you mix with diesel and still have a diesel engine run.

      In small engines the only reasonable performance increases you should expect are due to better energy density of the fuel due to having no ethanol content. It's not so much about the lead or even the octane rating. I use 100LL in higher performance and higher compression engines where higher octane is needed. Never in EFI engines with o2 sensors because the lead fouls the sensors over time. It also fouls catalytic converters. I also use it in engines which don't get used as often because it is more stable than e10 gas. Again in this case it isn't about the lead or the octane but the stability that matters to me.

      It's also worth noting that in my research on this fuel, that I've read that even though they call it "low lead" due to a reduction in lead content over previous aviation fuels, it still has more lead content than road fuel has ever had. In my old truck I mix it with 91 octane ethanol free fuel to reduce the lead content to avoid buildup. It works great that way.

        How about a video to compare 5 or 10 year aged gasoline with fresh gasoline? (Maybe test flash point and some flame comparison with that clear cylinder head) Ive have gasoline sit for 5+ years and used it without any issues. Anyway great vid and I just added you to the "suggested channels" section on my YT channel. Keep up the awesome work bringing us pure results.

        What about a permanent marker competition. Sharpie, Milwaukee inkzall, cheaper brands. Tests of permanence, hot/cold, dirty surface, and amount of ink per pen.

        Even as an general aviation A&P leaded fuels are pointless and largely result in wasted time cleaning spark plugs for pilots who don’t understand peak richness.

        I would like to see you test the claim that Marvel Mystery oil added to gas increases engine life by improved lubricity of piston rings in cylinders. MMO should reduce friction. Use your bearing test fixture with gasoline and MMO at the recommended level.

        i can for a fact say 100LL is better then most fuels found at a gas station due to the fact it has almost no water its also got no ethenal and stays good much longer. we winterize everything with the stuff and it never fails to start next spring

        I wouldn't say leaded fuel is better but not running it in engines that were designed for it can be a problem. Valve seat recession on 70's and 80's BMWs from running unleaded for example is a well known issue that can only be solved by expensive procedure of replacing valve seats.

        It makes me wonder if that was the intention for man, to chase sticks and ducks, to name animals, to create families, and to keep looking back at God to feed off his pleasure at our pleasure.
        My father will hunt you for taking his power if he finds out,” he said into the frigid dark. “And kill you for learning how to wield it.” “He can get in line,” was all I said.
        They say you came back different. Came back wrong.” A crow’s laugh. “I never bother to tell them I think you came back right.

          So after watching I wanna say I love your channel first. Second, you gotta force more air in with higher octane. And let it breath out better. The exhaust will act as a choke on the back side building up just enough pressure to limit gains.

          Could you do a test what is the effect of oxigen enriched air intake ? Maybe pure oxigen ? Would the efficiency go up ? Would the engine be stronger ? How much more would it cost to mix air intake with oxigen ?

        • Louis-Philippe St-Jean

          Some people with modern diesel engines (common rail) put 2 stroke oil or atf in a 200:1 ratio on their tank because ultra low sulfur fuel is supposedly lacking of lubricity for the pump and injectors. It would be interesting to see on the lubricity tester how normal diesel and diesel with different lubricants or additives makes difference or not. Thank you!

          You should do a fuel comparison between "top tier" fuels to see which one is the best, most cost effective, cleanest, ect..

          • Adventures in mopeding

            Have you ever heard of the fuel stable called PRI-G you could do a video comparing different fuel stabilization products. That one also claims to restore fuel. You could also test that. Keep the good videos coming.

            Project idea: I saw a video where waste plastic was turned back into oil by heating/melting the plastic and venting the exhaust through a water bath. Wonder if you could use this oil as fuel? Great videos! Keep it up!

            YOur videos keep getting better and better.
            This shows that 100LL has a LOT more lead than lead-free (I know this SHOULD be obvious, but talk to the average person)

            I especially like how when you give a piece of data you give the before also (REALLY LIKE THIS!).
            Once again, thanks.

            Super cool video and clips. I’ve been running avgas in my small engines for the last 8 yrs, so I was really interested in the results. I feel like this video needed a conclusion... after watching I don’t know.. that was a lot of lead build up

            I just want to say great work on the video. I hope that you had a lo of fun making the video. I never heard of this type a fuel before. I would like to see you try testing table saw blades to see if brands makes a difference or not. As always I am looking forward to the new video that is coming out on Monday again. I would just like to say one last thing take care in' till next time!

            The lead is not good for the 4 stroke engines. Todays 100LL contains far more lead than car gas ever did. About 4X as much. I run it in my two strokes, and generator due to the long storage life. Rated at 5 years for aviation use, shelf-life is more like 10 years.
