Fuelled or Fueled – Quick Answer

Both fuelled and fueled are correct spellings.
The difference depends on British English vs American English.

• Fuelled → British English

• Fueled → American English

The Origin of Fuelled or Fueled

The word fuel comes from the Old French word fouaille, meaning firewood. It entered English in the Middle Ages and later became a verb meaning “to supply energy” or “to increase intensity.”

The spelling difference exists because:

• British English often keeps the double “l” when adding endings like -ed or -ing.
  
• American English often drops one “l” to simplify spelling.
  

This pattern explains why British English prefers fuelled, while American English prefers fueled.
