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

Published on Aug 12, 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 RUvideo channel for loaning his rotary engine to me! Please check out his channel. His videos are absolutely amazing!!!

  • Nice, the first video about leaded fuel. Did the smoke smell different? This is much build up of lead inside the chamber. I think in the list at 2:27 1,2-dibromoethane or 1,2-dichloroethane is missing as lead scavenger. They flush the lead out of the engine.

  • Winter is quickly approaching. Could you test different diesel fuel additives for cold-weather anti-gel effectiveness? PowerService, HEET, and Stanadyne ect..

  • Oooo hot lead fumes.

  • On the rotary engine, the lead level itself acts as a lubricant. Try the rotary without 2 stroke oil and watch the difference.

  • 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?

  • Loved the Video Did you see dome one ended ti the hospital what are they doing? like the videos

  • Heres a project 😀😀 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?

    • Kerosene is indeed a common ingredient in fuel treatment additives whether for diesel or gas (petrol for us in The UK). I think it's primarily used as a carrier for the other components. Fuel treatment makers are very covetous about what goes into their magic potions.

  • 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.

    • Tetra-ethyl lead is also hideously toxic to both humans and to closed loop cats.

    • Thank you

  • Liked it!

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

  • Project Farm: *has something with an engine in it" Project Farm: "Im going to put this baby through so much" Engine: :(

  • can brake fluid be a paint remover do a show on this plus the active ingredient i been told in brake fluid is hydroscopic can you prove or disprove may take a few days or weeks to prove

    • All brake fluids apart from DoT 5.0 are highly hygroscopic.

  • Potassium Chlorate explodes upon friction. Would the moving actions of pistons be enough to explode the powder and give horse power?

  • 👍👍👍👍👍👍👍👍👍👍👍👊👍

  • 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?

  • Probably shortened your life by a good 5 years.

  • His neighbours must always wonder why this guy is constantly bringing lawn mowers to his house.

  • 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

    • You didn’t get the point of the video? USELESS comment

  • I would be very concerned about you using leaded gasoline. But anyways nice video

  • 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?

  • Avgas burns a nice pretty blue...

  • Last time I even smelled leaded gasoline I had an instant headache and it lasted for hours.

  • All you need add salt and pepper to that gasoline...

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

  • Any help is appreciated 👍🏻👍🏻

  • I’m having trouble my friend I bought a compression tester and it reads 30 psi on both engines I’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

  • Hey, You could hone the cylinder wall with each test too, If you wanna!

    • @Project Farm If there are more hones out there, see what brand maybe best!

    • Thank you for the video idea!

  • Now what about leaded fuel in a car with no sensors? Like an old carbureted one

  • 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.

  • Lead fuel is great for lubrication and cooling, great for prevention of knock

  • If you havent already done so you should do a video on “add to gas tank” 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

  • Instead of aviation fuel, try Red Bull...

  • whos using gas as a skin cleanser seriously why is that even in the safety data sheet

  • I recognize that pullstart mod on your predator engine

  • Another informative video good job

  • Cadillac converter....lol.

  • Very bad voice. Listen how he says oil...

  • I wonder where he got Avgas. Normally, (lawfully) it can only be dispensed into an aircraft fuel tank....

    • Flies2FLL here in Idaho I can go to the local airport and pump it into anything besides a road vehicle I’d like

    • I got it from a friend.

  • Test different brands of bleach for whitening power? Clorox vs store-brands from Wally world, dollar general, target, etc

  • When I was younger I drove tow trucks. Long haul on gravol . And was told that if I lost my antifreeze. Say a rock hit the rad. That if I could fix the leak to use diesel fuel for antifreeze. Never happen to me but still curious if it would work? Thank you

  • Its more about what fuel the engine is designed to run on.

  • Let’s test that on the new GTR 🤔

  • Violent crime has gone down every year since leaded fuel was banned. Think about that.

  • My GFs malice vs my will to live. Go

  • Can cause problems with the catalytic converter. Simple, remove that piece of shit.

  • Love it.!

  • Will atf work in place of two cycle oil?

  • Got one for you to do and it would be cheap compare fuels by adding oxygen to gas vs methane vs hi test you can add oxygen tablets like they use in bait wells for oxygen

  • Can you use Jet A-1 fuel to diesel engine? Diesel engine and gas turbofan use high compression to burn the fuel
