Back in the late 80s/early 90s my elderly Italian-speaking grandfather lived with us in the states.

Whenever he'd watch driving my gas RC car, if the thing would die he'd motion with his thumb down (like a pouring spout) while saying "benzene?".

I don't know if it's an Italian language thing, his dialect, or just his knowledge of engines, but RC car fuel was "benzene". Makes me wonder what kind of benzene exposure he had in his younger days...
