  • 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!!!

    Would love to see NOS through the see through engine!

    In theory, higher octane by itself should not improve performance, and it might actually decrease performance as the engine is not optimized for it. The purpose of higher octane fuel is to allow higher compression without knocking. This is why putting premium gas in a car that doesn't need premium gas is a waste of money - the engine wasn't knocking to begin with.

    I like to see a comparison between low price vs high price gasoline I believe when prices are low companies put less additives in, I'd like to know if that's a fact, it seems like I get worse gas mileage when the prices are low! Thanks!

    Great Videos. I have used 100LL extensively in 2 stroke racing motorcycles since the 1980's. I have not seen the type of buildup that you are seeing with 100LL, which contains 2.12 grams/gallon of TEL. Typical 2 stroke cranking pressures of 175-185psi may have an influence on the cylinder temperatures and how the TEL is consumed in the combustion chamber. I have also gone back to using Kemco Octane Supreme in 91 Super Unleaded. Kemco TEL concentrate contains 59.5 grams/gallon of TEL in a Tolulene suspension. in my 1982 Honda XR500R Desert Motorcycle, compression during cranking is a whopping 225 psi. I have found that 2.4 ounces/gallon of Kemco TEL provides notably smoother running, better hot and cold starts and zero deposits on the spark plug. To take this a step further, I tested the Kemco TEL at a very high concentration in a 5.5 horsepower Briggs & Stratton lawnmower at 10 ounces per gallon. Plug color was very even light gray without any 'textured' deposits. In an engine with a very high static compression ratio, I find it necessary to use TEL to prevent high-rpm detonation. It is of little if any value in other applications. Have you experimented with Chevron Techron Powersports Ethanol Stabilizer??? I have had good results in extended storage of fuel in lawnmowers. It would be interesting to see your evaluation...

    Lead had two functions. First to boost octane and second to lubricate valves. We used to get 102 octane at the pumps (the good stuff) and aviation fuel was 120. When lead was no longer allowed the octane dropped drastically and difficult to replace at the time. Older engines had to have lead additive purchased separately. If not the valves were quick to go if the detonation of the low octane fuel didn't blow holes in the higher compression pistons first. High octane fuel burns longer for higher compression engines. Low octane fuel burns fast and essentially explodes causing the "ping" heard from an engine. That's the top of the piston being rung like a bell. Modern engines aren't built to burn high octane fuel and don't need lead lubrication and there isn't any benefit by running it. Unless you drive an airplane or race car to work. :)

    I hope you do realize that you just got lead poisoning by inhaling the exhaust................

    That makes for a very neat video, but you understand what leaded fuel is intended for for aircraft engines? Do you understand what leaded fuel is for.? And ask for oil additives that you test how about a product called power Punch?

    There is little to be learned regarding the presence of lead in the fuel because of the vast difference in octane. The problem is with the timing. Higher octane fuel resists burning longer than low octane fuel. That explains why the fuel injected engine had no problem, because it is able to adjust the timing. There is a leaded low octane aviation fuel but it is difficult to find. I believe it is a dyed a reddish color.

    Rotary engines are fun but a pain in the butt to work on if you don't know what you're doing. A buddy of mine and I used to joke though that they'd run on just about anything. But, I do actually think, as long as whatever you run it on is combustible, it will run on it.

    I heard they used leaded fuel back then because it was quieter and made engines vibrate less. They were actually aware of the hazards of leaded fuel but used it anyways. It wasn't until later when it became widely known that spewing lead into the air is not healthy.

    Here's a dumb but cool idea you should. But try vape juice as an oil substitute.😂

    The poblem comes doing the opposite, using unleaded fuel in very old engines it damages the valves and valve seats i use an additive for that purpose.

    I remember on a local car forum I was on a fella with a pretty well built 302 in a ranger had to change his float setting with av gas. Different specific gravity. Sunoco even mentions it on their website about race gas.

    interesting video, but on the MSDS, the flaspoint is measured as lower then 40°C, not actually -40°C (<=)Secondly, Avgas has a lower vapour pressure, and has higher sulphur content then normal E10 gasoline. Its not comparable to normal gasoline as you found out, so please don't run that stuff in your car! Engines made for avgas are constructed way differently with normally higher compression ratios as the oxygen content is thinner higher up, so more air needs to be pushed in. And weight to horsepower ratio matters alot in a small plane.Avgas 100 stands for MON 100, not RON 100 which is euro 95/98 (Ron 95/Ron98 with Mon in the 86-87 range if i'm right) For your examples that realy doesn't matter as they don't use high compression, but a turboprop engine from a plane does use pretty high compressions so thats why the MON is 100 compared to 86-87 of euro 95. I would love to see a comparison on a high compression engine running avgas vs euro 95 to actually see that difference (run a aviation engine made for avgas on regular gasoline!!)Regards, laboratory analyst of a refinery checking that stuff daily on national and international specifications.

    Leaded fuel was used to protect the valve seats on pre 1950's cars. They did not have the harden valve seats back then. The lead helped with the valve seat from wearing out prematurely . Todays engines have the harden valve seats which resist wearing and do no require the lead in fuel. I am sure leaded fuel will clog or harm fuel injectors and catalytic converters and o2 sensors on modern cars.

    The Lead in Gasoline was there to provide lubrication to the engine. It also creates deposits as you have shown.
