What is MOGAS - and why is it so relevant?
MOGAS stands for "Motor Gasoline" - essentially it is premium petrol (usually RON 95), as is also used at petrol stations for cars. However, not just any petrol can be used in aviation. It must ethanol-free and meet the requirements of engine manufacturers and EASA operating licences. The advantages of MOGAS over Avgas 100LL are obvious:
- Cost savingsMOGAS is on average 30-50% cheaper than Avgas.
- More environmentally friendlyMOGAS does not contain tetraethyl lead, which is used in avgas to increase the octane rating and is harmful to both people and the environment.
- Technical advantagesSome modern engines - especially Rotax, ULPower or newer Lycoming models - are specially designed for operation with MOGAS.
However, MOGAS is not available everywhere - and this is precisely where the annually updated directory comes in.
The new MOGAS Map 2025: overview and benefits
The new MOGAS Map 2025 provides a detailed overview of all known aerodromes in Germany that offer an official supply of MOGAS or ethanol-free automotive fuel. The map shows
- Name and ICAO code of the aerodrome
- Availability of MOGAS or automotive fuel
- Information on refuelling options (e.g. fuel card required, self-fuelling, refuelling only with advance notice, etc.)
- Contact details or further links
This card is a particularly valuable tool for:
- Private pilots with MOGAS-capable aircraft who want to plan cross-country flights more efficiently
- Flying schoolsthat operate with cost-sensitive training models
- Clubswho want to optimise their operating costs and fly more sustainably
Availability and download
The map can be downloaded free of charge. The latest version is distributed via relevant aviation forums and René Mühlmeier's website, among others.
Important notes on use
As the supply situation can change quickly, it is essential to verify the information before each flight - ideally directly at the airport by telephone or via the respective website.
Looking to the future: lead-free avgas as a beacon of hope
In the long term, the industry will want to rely on a standardised, unleaded avgas. With UL94 (unleaded avgas with 94 octane) and the avgas already authorised in the USA. G100UL by General Aviation Modifications Inc. (GAMI), new fuels could revolutionise the market in a few years' time. Until then, however, MOGAS remains an important transitional solution - both economically and ecologically.
