TERRIBLE PLAN
Can I put cooking oil in my car?
No, putting cooking oil in your car is a terrible plan unless you want to bake your engine instead of your dinner.
Cooking oil is not designed to run car engines. Vehicles require specific fuels like gasoline, diesel, or approved biofuels. Using cooking oil can clog your engine, damage fuel systems, and leave you stranded with an expensive repair bill. Unless your car is a Frankenstein diesel modified for waste vegetable oil (which is rare and complex), just stick to real fuel.
