Transformer fuel

Transformer fuel is a substance from the Marvel Comics portion of the Generation 1 continuity family.

Transformer fuel is a liquid substance used by Transformers to sustain their mechanical life. It is not a hydrocarbon, but with the right technical know-how, it can be converted from hydrocarbons. Transformers can drain some of their fuel by removing their hand and allowing the fuel to pour out their forearm. Fuel from within one group of Transformers can be used to re-energize a second group of Transformers by utilizing Tubes of Transference.

The mingling of Transformer fuel holds special significance and is used in rituals such as Rite of Oneness and the Rite of the Autobrand.
