Fueled and fuelled are both correct spellings, but fueled is standard in American English, while fuelled is standard in British English. Both forms are the past tense and past participle of the verb fuel. The difference is mainly a spelling rule, not a difference in meaning.

The same pattern appears in words such as canceled/cancelled, modeled/modelled, and labeled/labelled.

The Origin of Fueled or Fuelled
The word fuel has a long history. It came into English through Old French, from the Latin word focus, meaning “hearth” or “fireplace.”
Over time, fuel came to mean material used to produce heat or energy.
English later developed different spelling conventions in different regions.
American English generally became more likely to use -ed without doubling the final l in words such as:
- fueled
- canceled
- labeled
- modeled
British English commonly uses the doubled consonant:
- fuelled
- cancelled
- labelled
- modelled
This is why fueled and fuelled developed as regional spelling variants.
The difference is mainly about English spelling conventions. It does not indicate a different pronunciation or meaning.
British English vs American English Spelling
The main difference is the number of l letters.

fueled

The same pattern appears in several other words.

| labeled | labelled |
| modeled | modelled |
| traveled | travelled |
| signaling | signalling |
For example:
