Default PAFI. What killed Swift Fuel candidate

Rather than creating thread drift in another lead/AVGAS forum, I'd like to start here. Many know the seemingly quiet death of PAFI. Swift fuel seemed very promising and I have friends who buy it in bulk/are very happy with it. It appears Swift is only pursuing the STC route now.

Real info is hard to find. Anyone have any knowledge they can share regarding Swift's "exit" from the PAFI initiative/death of PAFI. Ex: lots of talk the big producers campaigned Swift's PAFI demise? Anything would be appreciated. Thanks.

IMO, the people in the agency pushing the very challenging project get paid whether they complete the work or not. Guess where that goes.

Default Current unleaded

If the current unleaded fuel becomes available in California, Nevada, Arizona, I am all in, even if it is slightly more expensive,

The airport manager at Reid Hillview and San Martin Airports is investigating using Swift; they are hiring consultants, so it must still be alive.

Poorly worded on my part. It is available though pretty limited. It was the leading candidate to replace 100LL in most people's view. Then somewhat suddenly, the efforts associated with PAFI seemed to stop. As mentioned, the STC efforts seem to be alive and well.

This popped up on Swift's website a few months ago as far as I know:


"Swift 100R is a 100-Motor-Octane aviation gasoline designed to fully replace 100LL Leaded Avgas across the entire global piston fleet

FAA Certification testing and ASTM fuel specifications are currently in-progress

Sign-up if you would like to collaborate with Swift Fuels as we strive to fully replace 100LL, click here.

If you want to financially support our efforts, buy a $100 FOREVER Avgas STC from Swift Fuels for your aircraft, click here.

Contact Us to Order Swift 100R"

This is different from the UL94 they have been selling nation wide for a number of years.

It's not clear if 100R will be FAA approved without an STC or not though.

I believe GAMI also dropped out of PAFI with their G100UL fuel and nothing has been updated since 2017 that I've seen so hard to know what's going on with them: https://gami.com/g100ul/news.php

I find this comment rather disingenuous. My experience is that federal employees in science-based branches of federal agencies are highly motivated and conscientious at fulfilling their agency mission.

I looked into the cost of fuel from Swift, it only works out on large scale and volume in order to keep costs low. I would love to run it, my engine was made for 80/87 which does not like the higher lead in 100LL

I am not surprised that a government project isn’t moving along or getting results. IMO Gov’t couldn’t find their way out of a wet paper bag.

How much compression can you run with the 94UL? (no turbos)

Depends on ignition timing. With programmable EIs, some folks are running up to 9 to 1 on on mogas which is lower octane than this. You just limit timing a bit at high MAP and have full advance in cruise where MAP is lower.

You take a small HP hit at TO power and sea level. Cruise performance at altitude is unaffected from what we see.
