Is Leaded Fuel better than Unleaded? Let's find out!

  • Published on: 12 August 2019
  • Is leaded fuel better as than unleaded gasoline? 100 octane low lead aviation fuel (100LL avgas) is tested in several engines: Wankel rotary, see through piston engine, fuel injected generator, small engine for lead build up, and Predator 212 for top speed performance. A special thanks to Matt from the Warped Perception YouTube channel for loaning his rotary engine to me! Please check out his channel. His videos are absolutely amazing!!! Also, thanks to all the viewers that requested this video. Thank you very much for supporting the channel by watching the commercials and through Patreon support.

    Try running a 2 stroke on E85 mixed with oil or isopropyl mixed with some oil .

    There is a lot of debate about low-vs-high octane fuel, with many reporting reduced power and/or fuel economy as well as increased carbon deposits when running higher-than-recommended octane fuel. I know it would be difficult to test power numbers, but I would enjoy an economy and carbon deposit shootout. I would think using Top Tier fuel from the same station- preferably one with different hoses/nozzles for each grade- and the same ethanol content for each would eliminate a lot of variables and help silence the armchair quarterbacks.

    have you tried running the engine off beer or other alcohol used fro drinking? pabst blue ribbon?

    Heres a project ๐Ÿ˜€๐Ÿ˜€How about making a extended run system that works with a membrane pumping like on the riders . If you have a generator and you would like to place un external fuelcell to it and it is not always possible to place the fuelcell higher than the carburator , how would you connect the pump on the motor ? Lets say that you take and place a fuelcell 8 feet from the motor and you whant to run it from the fuelcell , from time to time it needs more gas and i would like to refuel it safley without turning it off. Any ideas?

    Can a piston engine run on 100 percent ethanol? What about methanol or thinner?

    You should make an electrolysis machine and run straight hydrogen thru an engine with a lot of carbon build up and see if it cleans it out. They say it will. Thanks man enjoy all you videos

    Great channel. Just the fact that a young man has the time and money, and property to have all this fun, and all the time to set up, film, edit, etc. almost restores my faith in humanty, and the possibility for success in life.

    I'm very skeptical that the clumps in the engine were actual metallic lead. I would have guessed they are some oxide of lead, or of another chemical in the fuel. If they are metallic lead clumps, you can scrape them off and easily melt them with a blowtorch into beads. Care to test that out?

    Dont they use jet fuel in gas treatment?

    The problem with running the leaded fuel isnt the lead but the octane that is to high for those low compression engines. A gas engine will make less power with more octane than needed contrary to common beliefs as proven at drag strips.

    Excuse me usage of lead in fuels is banned in EU. Is lead allowed in US? :O

    that generator will run on almost anything, that could come in very handy in a bad situation! Does marvel mystery oil increase octane when mixed with gas say around 2 ounces to a gallon of fuel?

    It would probably be OK in an antique car or truck made for leaded fuel

    What did the cylinder wall look like before and after the leaded gasoline? I would expect buildup - and hence less scratches - there too.

    AVGAS was produced in WWII to deal with extremely high combustion pressures in supercharged aircraft engines. The efficiency is due to high compression yielding better combustion. If you don't change the design to use AVGAS, then the test is just meaningless.

    you didn't advance the spark timing to take advantage of the higher octane. USELESS test

    How about NOS on the go cart? Does it have a soiling effect on your pants or is it just flat out fun? Does it work better with avgas or regular fuel?

    Lead fuel works better or if you use Aviation fuel that's even better than street gas.

    Iโ€™m having trouble my friend I bought a compression tester and it reads 30 psi on both engines Iโ€™ve tried it on but when you take the hose off and use the short metal pipe that came with it it is about 60-70 would you have any idea why this is

    This test doesn't tell anyone anything except that you should run the gas the manufacturer recommends. They're smarter than you.

    VP U4.4 or VP MR12 race fuels. They are oxygenated fuels. I know my generators and small motors seem to run much better when i put my leftover U4.4 in them at the end of the year. Be interesting to see you do a test involving them.

    If you havent already done so you should do a video on โ€œadd to gas tankโ€ carb/injector/valve cleaners in a car and small engine. Would like to see seafoam vs walmart brand eq. as well as gumout, stp, etc
