  • 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!!!

    They're both the same. When I sampled some of each on two different occasions, I ended up in hospital emergency both times.

    100LL is DEFINITELY superior if your snowblower sits for long periods of time without being used...WAY better on hoses and gaskets

    Test cooling system sealers. Heard none of them really work.

    The only truly unbiased channel in the entire Youtube platform. Even when the comparison is not really practical like this one, it still very entertaining to watch!
    You have my respect!

    The leaded gas sure does look nicer, smells and tastes sweeter too :)

    Correct, you do NOT want to run LL fuel in a modern fuel injected engine. The motor will be fine, but you will absolutely destroy the O2 sensors, as the lead poisons the platinum wire in the sensor itself. It will also cling to the cats. But if you have a race motor with speed density and no exhaust side sensors, or a carb, have at it.
    One other thing the older engines had too were valve rotators... they continually changed the position of the valve every time it closed so it wouldn't let lead buildup mess up the sealing.
    If you had an old engine and didn't run leaded, even high octane, you'd still kill the valve seats as the rotators would chew right through them.

    Wifey: Honey will you pick up a Grande carmel frappuccino at Starbucks on the way home.?
    Project Farm: I have to see how well it will run in the lawn mower and how many deposits it leaves on the cylinder heads first.

    Where do you get all your mower parts from? I probably need to throw some new gaskets on my 24ish year old Toro...
