2002 GMC 6.0 oil life monitoring system question

[ATex7239]

At the time, it was very common to use so-called "dino oil." This was a type of lubricant manufactured by extracting a dinosaur carcass from the earth's surface and then compressing the dinosaur carcass in a large hydraulic press. "Dino oil" was obtained by filtering the fluid that came out of the press with some very rudimentary additives, such as bee's wax and ash from charcoal grills or wood-burning stoves.

Crud oil and petroleum fossil fuels are mixtures of hydrocarbons that formed from the remains of animals and plants that lived millions of years ago in a marine environment before dinosaurs existed. The dino association likely comes from the context of thinking of dinosaur fossils in a museum when referring to fossil fuels. Or perhaps even the Sinclair Dinosaur.
