The FAA has expanded approval for Swift Fuels’ 100R unleaded avgas, adding 88 engine makes and 840 engine models to the approved model list under the company’s supplemental type certificate.

The move marks another step in the industry’s transition away from 100LL, while Swift continues work toward approval for additional high-compression engines that still require broader certification. Swift’s lower-octane UL94 fuel remains available at more than 100 airports, while 100R continues moving toward wider adoption.

U.S. aviation fuel prices moved sharply higher in March, with broad-based increases across major fuel types nationwide, driven in part by ongoing developments in the Middle East.

National JET A Full Service averaged $7.64 in March, representing an increase of $1.23 (19.2%) compared to February. Excluding Alaska and Hawaii, Lower-48 JET A Full Service averaged $7.59, up $1.26 (19.9%) compared to February.

National 100LL pricing also moved higher in March. 100LL Full Service averaged $6.80, an increase of $0.38 (5.9%) compared to February, while 100LL Self Service averaged $5.69, up $0.25 (4.7%), reflecting an approximate 16% savings where self-serve options are available, up about 1% from February.

For MOGAS and UL94, pricing also moved slightly higher in March 2026. UL94 Self Service averaged $6.88, up $0.01 (0.1%), while MOGAS averaged $4.73, up $0.06 (1.3%), with both fuels continuing to show limited and highly regional availability nationwide.

Colorado’s Rocky Mountain Metropolitan Airport (KBJC) has begun offering unleaded avgas through Sheltair Aviation, becoming one of the latest airports in the state to add Swift Fuels UL94 as an alternative to 100LL.

Sales began in February with support from a state-backed initiative designed to help keep UL94 priced competitively while also reimbursing eligible aircraft owners for required supplemental type certificates. The move adds momentum to broader efforts aimed at reducing lead emissions from piston aircraft, particularly at busy general aviation airports like Rocky Mountain Metro, which has faced increased scrutiny from nearby communities over environmental and health concerns tied to leaded aviation fuel.

Aircraft fuel planning requires a careful balance between safety, efficiency, and operational flexibility. Carrying too little fuel increases risk, while excessive fuel adds weight, raises burn, and can limit payload. Operators must account for variables such as weather deviations, air traffic delays, alternate airport requirements, and company policies when determining appropriate fuel loads.

Advances in flight planning tools and data availability are helping crews make more informed decisions, enabling more precise fuel strategies that optimize both safety margins and efficiency without overcompensating.
