When I came across the fuel tag, I assumed it related to automotive fuel, like finding diesel stations, or about fuel pre-purchase options for rental cars. The actual questions tagged are rather different:

• Two about purchasing fuel for camp stoves
• One about an airline fuel surcharge
• One (closed) about refueling a private plane
• One (closed) about the best day and time to buy gasoline/petrol in Germany

I don't see any merit in repurposing [fuel] to serve any of its existing uses. Should it be deleted? I could not find any suitable synonyms to propose. gasoline is a synonym of automobiles, and there are no questions tagged as petrol or diesel.
