AVGAS UL 91

AVGAS UL 91  

Avgas UL 91 is now available in our general aviation network. It is a new fuel aimed at the general aviation market.UL 91 is a colourless, unleaded aviation gasoline that we designed initially based on Rotax engines - and has since been endorsed by Rotax for the 912 UL/A/F, 912 ULS/S and 914 ULF/F engines (read the Rotax Service Instruction).

Thousands of motors across Europe can use Avgas UL91. Modern flex-wing microlights, modern autogyros, and popular aircraft such as the Alpi Pioneer, Aquila, Banbi MCR-01, CT2, Europa,  EV-97 Eurostar, A-22 Foxbat,  C42 Ikarus, SportCruiser, Tecnam P2002 and Twin P2006 can all benefit by switching to UL 91 today.

Unlike Avgas 100 LL, Avgas UL 91 is an unleaded fuel, which means it is cleaner for the environment and it meets the international standard ASTM D7547.
