100LL Interruption?

Look around! :rofl:

Flat earth, faked moon landing, vaccines/5G, chemtrails... Americans seem to be dumber than ever these days, and we burn more 100LL than anybody. Not exactly "case closed" but it's definitely believable that lead has affected us! (Note that I don't think so either, but... Wow, there's a lot of stupid these days.)

I travel most of this globe, it’s posh to say such things, but having traveled Asia, euro, S America, I just laugh a little and shake my head when the proverbial American suburb types try to self flagellate

back in the 60’s, BLLs were at least twice what they are now, and we landed men on the moon!

But that offset is offset (and then some!) by a need to restore paint damaged by G100UL.

If you're getting fuel on your paint, you're doing it wrong.

Seriously, don't we all take care not to spill or drip fuel on our cars, motorcycles and planes? If someone spills gas on my car, they're going to get an earful (or worse). Why is paint compatibility a legitimate concern for GA aircraft?

As noted above, 100LL required re-sealing some existing wing tanks. We accepted that sort of transition cost then, and we can accept it now.

Occasionally when I pull the fuel nozzle out of my car's tank, a little fuel will drip onto the paint. It does no harm to the paint. Furthermore, I always fuel my car myself, but my plane is occasionally fueled by line people who may not bother to rinse off a little bit of fuel.

Avgas will get onto the airplane's paint once in a while. It shouldn't cause damage when that happens.
 
For me the most worrying reports with G100UL are not the paint damage. Paint damage will not kill me.
It's the reports of swelling o-rings and gaskets. That can stop an engine.

About ten years ago a study came out showing that crime rates decreased at the same rate as lead contamination. I was going to look for follow-up peer review studies to verify but I’m always hyper focused on my next caper

That's why the population is the dumbest, riiiiight?

My last car, fuel would always spill onto the body before the pump shut off (known problem with this make/model) unless I pumped very slowly. It didn't hurt the paint.

My current plane, where the filler cap is located it's almost impossible to fuel it without spilling a tiny bit on the paint. Especially when you land at an airport with a fuel nozzle better suited for a Constellation than a Cub or Cherokee...

I’ve read that, too, and am a bit skeptical that it’s primarily the reduction in lead that resulted in reduced crime. At the same time, education levels were increasing, alcohol use was decreasing, nutrition improved, prevention and treatment of diseases improved, people were becoming more traveled and had more leisure time. I doubt that any single factor can be credited, but life becoming easier, happier and healthier has to go a pretty fair distance in cutting violence.

It was in Freakanomics or some similar book. One of the striking claims is that other countries that phased out leaded gas (at different times than we did) experienced the same drop in crime about two decades later as well.
 
If any vehicle i owned was damaged by fueling it, i'd take it the hell back. That's just dumb as ****, No i shouldn't have to be overly concerned about stripping my plane when i fly it
 
I’ve read a lot of studies. If methodology isn’t shown or it’s labelled @meta-study/meta-analysis”, it’s as rigorous as stamping “anecdotal” on it.

There’s very little original research done today, especially identifying causal relationships; most focus on correlations.

Even that isn't necessarily true anymore. GAMI 100UL has the closest thing to a universal STC probably ever issued. It just needs wider distribution, but it's making progress. It is a bit more money, but that is offset by reduced frequency for oil changes and an overall reduction in maintenance cost by not having lead gumming everything up.

Plus the price differential will largely disappear once volume increases. For low compression engines, there is no difference in using 100LL vs unleaded auto fuel, other than the absence of lead fouling related issues. The same is likely to be true for G100UL for higher compression engines.
 
Our best performance and cost, anecdotally, was with a mixture of %20 100LL, and %80 ethanol free unleaded auto gas. 0-200.

What reports of problems with o-rings?

The "problem" was only shown with o-rings not installed. GAMI did a lot of testing of o-rings INSTALLED in things like fuel selectors and such.

I have an experimental with an auto conversion. I generally mix 30% 100LL with 70% E-free auto fuel. Works well for me. I could run straight auto fuel with a timing change (as I can only find 90 oct) but that brings about a small reduction in power. I also seems to start, idle, and run better overall with just a bit of the 100LL in the tank.

As for the G100UL ... I'm gonna sit on the sidelines and watch until more information is available.
