Late in WWII very high octane 115/145 aviation gasoline (read: lots and lots of TEL) became available for Allied frontline fighters, giving a performance boost.

Late in WWII very high octane 115/145 aviation gasoline (read: lots and lots of TEL) became available for Allied frontline fighters, giving a performance boost. When cruising, pilots had to periodically rush the engines to full power in order to burn off the lead deposits on the spark plugs. And the spark plugs had to be replaced after every flight.
