GAMI Unleaded gets approval

[Joe Larussa]

GAMI Unleaded Avgas Approved For GA Piston Fleet
In a first for the aviation industry, the FAA has approved supplemental type certificates (STCs) for the use of General Aviation Modifications Inc.’s G100UL 100-octane unleaded avgas in all general aviation piston aircraft.

I was just reading the article to confirm it was going to cover the high compression engines as well.  I didn't see anything that indicated it wasn't going to.

This is exciting news! Eager to see what the cost will be since I’m sure CA will be the first state to ban 100 LL.

In the AOPA article GA moves closer to unleaded future - AOPA they quote Braly:

"“It’s not going to be unreasonable,” he said. “Pilots in America will not be paying what they’re paying for avgas in Europe today.”

A quick look at Avgas 100LL prices in Europe show 2.15 - 3.35 euro/liter.  That is $8.10 - $12.22/gallon.  

EDDB - Berlin-Schoenefeld | Aviation Fuel Prices AV-FUEL.COM  (this is an interactive map of Europe showing all airports)

Also AOPA Pres. Mark Baker said "AOPA continues to encourage all fuel manufacturers to follow through with their own formulations, Baker said. “We’d like to see several fuels available that all work together and blend together. Competition is always a good thing for the markets.”

There is no competition.  And if it yields savings from reduced maintenance costs and long engine life since it may allow the use of modern synthetic detergent oils then the fuel producers and distributors will work to value price the fuel, extract some of the plane owner savings and cream off higher margins.

Already banned at my airport in CA for 8 months now.

That’s what I’m hoping for. I wonder even if engines running 100 UL and synthetic oils will have a longer TBO.

To use G100UL you would have to purchase a STC from GAMI?  vs FAA approves use of G100UL in all airframes in the AML as an alternative to 100LL?

I'd probably still stick with dino oil for a while unless 100LL completely goes away.  If you use synthetic oil, you just know you'll wind up out of gas at an airport with only 100LL

Synthetic oil still starts from petroleum ….

Let’s celebrate the first MSer to fill up with G100, and fly it until the tanks are near empty…

Better than that…

Let’s celebrate the second time they fill up…

 

Call me skeptical…

If you get the STC you can run on any combination of the new stuff and 100LL. It is approved for your engine at any blend ratio.

You have to purchase the STC if you want to be flying legally.

The challenge is extended…

The lead free fuel will re-enable use of synthetic oil…

Sythetic oil and its blends can be superior to what we currently use….

synthetic oil isn’t compatible with LL…

 

So there is some humor in there….

What do you do when you are using synthetic oil… and only 100LL is available…

Best regards,

If anyone needs a case or 30 of synthetic oil, I might know a guy

The FAA approved a Supplemental Type Certificate (STC) that allows GAMI G100UL to be used in all piston engine applications.  That STC is owned by GAMI.  The FAA did not confer airplane owners the industrywide right to use G100UL.  In order to have that right, an airplane owner has to buy a license from GAMI to use the STC,

[RobertGary1]

This is good to hear. some airports around here have already banned 100LL. Other airports are required to post warning signs to neighbors of the danger of lead. The epa has said federal ban is only 1-2 years out and groups have sued to accelerate that.

I learned something new this morning.  Thanks!

If I'm GAMI, I'm probably selling the STC for $10 or something so that I can get it into as many hands as possible as quickly as possible and sell more fuel.  Hopefully that's what they'll do.

This being aviation, probably $100.

I am not sure of the paperwork and record keeping on their end.

Not always.  You can start with natural gas.

Not according to Wikipedia. You probably could, but nobody does.

[Pinecone]

Pennzoil does.

You can go over to Bob's the Oil Guy forum.  A lot of people there feel that synthetics starting from petroleum are not true synthetics, since the oil molecules were not built up from smaller molecules, but cracked from larger ones.

If the people that used this back in the early 90's would have changed oil at 25 hours I don't think there ever would have been a problem. People thought "I can go longer with synthetic" and the lead created sludge eventually. I flew a TLS where the owner had used it in 1993 and 1994 and he never went over 25 hours on the oil. Had no problems.
