      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!

              Can you test Redline fuel system cleaner? Maybe compare it to ones you already have tested like Marvel and Seafoam?

              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.

              #Suggestion - I had a guy tell me that the often used starting fluid is dangerous: "A fire hazard." He suggested using WD40, saying it was every bit as good. I am interested. Thanks.

              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?

              Has nothing to do with this subject, but if you haven’t already done this, can you test 15w40 oils? I’d really like to see shell rotella and cenpeco in the line up. Thanks for all you do!!!

              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.

                Hey ProjectFarm. I cant find a way to send you a message. But i recently got a new vehicle, an 06, but still great condition. Id like to keep it looking its best and im wondering about best waxing products. Maybe you could do a video series of different waxes and tests to show the best product

                  I ran a 1990 BMW 525i on avgas for 9 years before I sold it, i did turbo charge it in SA , it developed way more power, ran and idled a heap better the exhaust burned a lovely cream colour and it never missed a beat, no sensor or cat problems it was in SA car magazine and on testing extensively, blew the M5 off very satisfyingly , I would line up amongst Cessna aircraft and fill the tank with this excellent smelling green fuel, which average around 119 octane , leaded back then in Cape Town SA, the only difficulty was the fuel dispensed at a much higher rate,so filling was quick and messy, great days

                      Look at all these subs. Been here from the start and can say....I told you so. Great job growing your subs! I remember when everything used leaded gas. My grandpa used it even after the made the tank fuel fill neck downsized, he hammer and punched it open and this was in the day of Service Stations. They'd warn him it was illegal but would still fill his tank. They stopped selling it before catalytic converters were ever installed. According to him that old Ford station wagon that he ran leaded gas in turned the odometer over so many times he swore that he thought it was over 700,000 miles. I believe it because he pulled a old small camper and traveled a lot, I mran a lot.

                      100LL is energy dense. It’s intended to be used at specific engine speeds. Beyond it being 100 octane and low lead it isn’t a stable fuel at higher rpm because of its burn characteristics. It also has a pretty specific oxygen content in it because it’s operated in lower density atmospheres than standard fuel.

                        100LL or AvGas is more stable and will not vaporise as easily as moGas(motor) so avgas will not make vapor lock when a rapid depressurisation happen like when changing altitude rapidly or at high altitude.
