During World War II, the increase in aircraftengine power led to the development of high-octane rating fuels to delay the apparition of “engine knock”. At the beginning of the war, most air forces used aviation fuel rated at 80 to 100 octane, but in 1945 more efficient fuels with octane ratings of 100 to 150 were commonly used.

With the advent of jet propulsion, such fuels became rare, leaving warbird operators to use Avgas 100 which in turn limited the power output of engines.

The polish petroleum company Walter Aviation has announced that it will soon commercialize Avgas 115/145, as the size of the world’s warbird fleet has made such a venture economically feasible.
