    I was wondering if AP fuel is really better than pump gas .

      Hey great video, but if you're going to mention a video, can you please reference it in description? Annotations don't work here.

      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.

      Can we see what happens when gasoline is run in a diesel engine/vise versa

      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.

      Could you try run an engine on ed's red? It's for gun cleaning mixture of ATF kerosene terpentine and acetone.

      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.

        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 ?

        I run it in my yz250 2 stroke dirtbike as a cheap alternative to racegas, as so do a lot of people that dont wanna run expensive racegas in their old beater bikes.

      • 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.

          Your expertise is needed! Duracell is claiming their new Optimum alkaline batteries have "more life in some devices, and more power in others." (always followed by an asterisk with no defining data, other than to say "compared to regular copper top batteries.)

          It sounds like BS to me, and needs to be tested whether there is more watt-hours of energy at a given current, AND if a higher current can be drawn at a given voltage.

          If you don't mind. I would like to say. then lead in gasoline main purpose is to coat the exhaust seat so the the valves don't wipe out the seat, Second unleaded fuel is only used on engines that have hardened valve seats , Testing of gasoline is done on the RON / MON Single cylinder adjustable compression engines , hence at the pump you will see. R+M/2. this means RON samples plus MON samples divides by 2 gives you a octane number . Most gasoline engines can run on 66 octane but under load will knock . just some FYI. info on unleaded & leaded gasoline

          I was curious: Trimmer cord is very specific in its diameter: .065,.080, .095, .105 etc.

          There's something else out there that you can get in those exact diameters: Piano wire, which is extraordinarily strong, durable, and flexible.
          ( ) The tensile strength of one popular brand of piano wire is listed as 2620–2930 MPa. By comparison, the tensile strength of a human bone is only 130. Wouldn't recommend exposing your fingers to this while it's on a trimmer.

          I was wondering if it would be better (or possible) to use piano wire for trimming?

          A video on various oil weights going through a coffee filter or a sieve at different temps would be interesting to see if those 0w 5w oils are really necessary for the new cars or if 10w would be fine with it

          Video idea maybe. Which gas station has the best top tier gas?
          BP, Chevron, Conoco, Costco, Exxon, Holiday, Kwik Trip, Mobil, Shell, Sinclair, Texaco.
          I wonder if b.p really does have the best gas to use with their "invigorate" or if they all aren't noticeably different.

          I do know If a fuel company can prove that their gas has additives and detergents that keep residue from building up on valves or in the combustion chamber, then they are qualified to call themselves a "top-tier" gasoline supplier. And for some reason ford recommends B.P.
