2 stroke oil in fuel for economy boost?

Don't know about those, but there is a high positive inverse correlation between tetraethyl lead and the adolescent crime rate.

en.wikipedia.org/wiki/Tetraethyllead#Effect_on_crime_rates

Although leaded gasoline is largely gone in North America, it has left high concentrations of lead in the soil adjacent to roads that were heavily used prior to its phaseout. Children are particularly at risk if they consume this.[118]

It's falling out of the sky every day a civilian piston aircraft is aloft.
The aero engines were never mandated to receive Stellite intake valves and chrome/nickle valve seats, so they still require low-lead AVGAS.

Think you have the valve materials switched, maybe, and 100/110 "lowlead" avgas has multiples of the car lead quantities. It is lower lead than 145 fuel and 80/87 is not readily available.
20 years ago I was able to have hardened faa approved seats installed in my O-290 lycomming and all the rubber parts were replaced with new style alky resistant AN hoses so I could buy a stc for cars gas.

For economy boost? That's a big negative for me. The benefit I saw is better fuel pump operation in aged vehicles.

While we are commentating on this: anybody ever add some dawn detergent dish soap to the fuel? If it doesn't clog, but disperses it should have the same effect.

Hmmmm need to take a mason jar and mix me up some. Double hmmmm,, dont have any gassers.

I remember seeing mentions of the usage of 2-stroke oil in fuel to prevent rust in the carburettors of some older vehicles due to the ethanol blends on gas.

Nowadays there are even ethanol-powered aircraft. AFAIK cropdusters in Brazil are now using ethanol more often than AvGas.

Thoughts? They’re talking about running it like 400:1+ in their fuel, maybe it helps lubricity of the fuel, cleans stuff, whatever? I mean, it’s an oil designed to be burnt and they do run it in rotaries…

you can look up the spicer lubricity test, an indepen scientific study on the lubricity of additives and 2 s oil was in the top results beating out commercial additives with a much higher price. 2s oil lubricates fuel pump very well, useful if you a diesel car that only takesulsd which doesnt lubricate fuel pump much

Older Diesel engines used to rely a lot on the reaction of the sulphur content of the fuel with the nickel content of some alloys used in the manufacturing of the pumps and injectors. On a sidenote, as biodiesel is often pointed out as a lube too, maybe it would be interesting to try Castor-based 2-stroke oil often used in racing karts, which may blend well not only to regular Diesel but also to some higher content of biodiesel.
