⛽ Fuel Pump is one of the animated emoji in Google's Noto Emoji Animation set — the same fuel pump emoji (U+26FD) drawn as a short looping Lottie animation. Lottie files are vector, so the animation stays sharp at any size and is usually much lighter than a GIF or a video.
⛽ is the fuel pump emoji, part of Unicode's Travel & Places group, added in Emoji 0.6 (2010). Unicode's keyword list links it with “diesel”, “fuelpump”, “gas”, and “gasoline”.
