Cooking oil is very much a staple in many kitchens as it is used in cooking meals, from frying, deep frying, stir fry, and whatnot. When cooking in high heat, you will need oils that are stable and won't turn rancid quickly.
One of the world’s greatest inventors was the first person to recognize other potential uses of cooking oil. Rudolf Diesel, the man who gave the diesel engine its name, started experimenting with cooking oil as a fuel source back in 1898.
