Experimental aircraft commonly use engines which consume AVgas (Lycoming / Continental / Franklin and equivalent types) or engines running Mogas (Rotax, Subaru, Jabiru etc). Some engines are capable of running either fuel, although with restrictions.
Purpose built diesel aircraft engines are designed to use JET fuel and can run on normal diesel fuel too. In this section we delve deeper into aircraft JET fuels, AVtur.
