  • 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!!!

    I mean, smoke with lead in it isn’t very good.

    Can you get your hands on some "zip fuel"? It’s a non-carbon based fuel with a higher energy density. It’s not too friendly to the engine and more expensive. It was supposed to be used for supersonic flight

    Used to run a newish Honda carb genny on avgas 130L damn exhaust used to glow under load

    I’m impressed they still make leaded gasoline. Guess we will never learn

    I used 100 octane leaded fuel in my dirt bike', but i had to diluted it with 91octane in order for it to run more efficient in my 2stroke" over all it ran much better,i ran it in my lawn equipment it ran much cleaner,Running it concentrated didn't notice any huge proficiency.my opinion it runs better if you diluted it,it reduces the lead content and want interupt
    The octane that will allow the engine to run cooler and much better.

    better? don't people know or understand why lead was added to fuel in the first place? if they did they would know why "better" really isn't a consideration.
    lead was added to lower the knocking noises that an engine makes, that's it, the performance between leaded and unleaded is all down to the octane level, which has nothing to do with lead. oh and gasoline is normally adjusted to be within a set range for it's octane level.

    How about leaded gasoline vs unleaded. Not aviation fuel....Can you even get it?

    Could you test disc brake pads? I recently had mine changed on my Lexus (4 wheel disc brakes) and now just days after being cleaned my front wheels are black with brake dust. Didn't happen before the change .Great videos keep them coming.

    Of course it's not better. Mechanical function has nothing to do with opinion. Lead was used in early model cars to help reduce engine knocking, boost octane ratings, and help with wear and tear on valve seats within the motor. Improvements in engine design, and better materials made lead something no longer needed. The title to the video is to generalized. "Is leaded fuel better than 87 octane in an antique Ford flathead engine with high compression pistons and original valves" , would have been a better title, since the question is specific to a certain engine, design, and specs. The title as it is makes it sound as if they can be compared as a matter of preference with no regard to application, giving uneducated audiences the impression that you may simply just prefer one over the other. One is not better than the other. It's like asking if a 10mm wrench is better than a 12mm wrench. Well if I need to loosen or tighten a 12mm bolt, then the 12mm is obviously better because it's made for that specific application that I need it for. 10mm wrenches were not designed to fit 12mm bolts. One is not better than the other, they are each made for specific things. It's a silly question I think.

    Today we're going to test ghost fuel vs regular gas. Lots of people claim that their engines produce more power and last longer using ghost fuel. Of course, ghost fuel releases howling specters when burned, causing souls of the damned to pour into our world, leaving ruin and madness in their tortured wake. Here's how we'll do the test...

    Before the catalytic converter, lead was used as an octane booster and valve lubricant. Amaco was the first brand to have all grades of gas unleaded.

    What? I can't wash my hands in benzine since I retired from the Firestone factory.

    Leaded fuel will ruin your catalytic converter as well as spark plugs, but is perfect to run in non-catalytic converter engines as aviation fuel has no ethanol and does not go bad like regular gasoline!

    The reason why aviation fuel ran richer in the go-cart was because it designed that way to provide better cooling for air-cooled aircraft engines (richer fuel mix makes engine run cooler). It also made the go-cart run faster because it is higher octane and provided more horsepower, that is why they run high-octane fuel in race cars.

    The speed will be the same because of gearing the av gas should run hotter and a stronger spark

    what the heck!! Not suppose to use AV gas a skin cleanser?
    What am i going to use now???

    did you ever do a test to see if ethanol gas will unfreeze a fuel line that has ice in it? its alcohol so would ethanol work better than isopropyl gas line antifreeze? or will ethanol gasoline keep water from freezing in your gas line? just an idea

    For something you may not know, high octane fuel does NOT mean more power. It's actually less power. High octane fuel is for high compression engines to prevent pre ignition. Put high octane in a car that calls for 87 octane, and you'll have a car that runs bad.
