It was on a Caterpillar grader, by the engine compartment. Even knowing that much I was still clueless about the warning.I thought warning signs were to impart understandable information.

Seems to be Sinclair... https://www.amazon.com/Sinclair-Dino-Gasoline-Sign-12in/dp/B000JVFUAK/Cool sign, but that dinosaur sign in the background needs some attention! Looks kind of like Sinclair, but not?
