One of our goals as a responsible energy supplier is sustainability and reducing environmental impact. Where fossil fuels must be used, we strive to make them cleaner, and that’s why we developed AVGAS UL91 – an unleaded aviation fuel designed for light aircraft, which is replacing the leaded option, AVGAS 100LL. As such, we are working with industry bodies and manufacturers to spread the use of this cleaner type of fuel.

The Light Aircraft Association

The UK’s Light Aircraft Association (LAA) has approved AVGAS UL91 for use in a range of light aircraft engine types, and a list can be found on the Association’s website. This gives domestic approval in the UK for AVGAS UL91 for registered aircraft with permits to fly on LAA recommendation.


TotalEnergies UK Ltd is a proud member of the United Kingdom's National Trade Body representing Business and General aviation.
