Can Gasoline and Diesel Be Mixed for Use?

It cannot be used. If diesel is added to a gasoline engine, the compression by the engine pistons will cause the diesel to ignite prematurely, leading to knocking and cylinder scoring. The piston hasn't yet reached the top of its stroke, but the diesel has already exploded, transmitting power prematurely. This is akin to an athlete giving their all in the final sprint, about to reach the finish line, when suddenly someone rushes out and forcefully pushes them back. Such damage to the engine is severe. Below are relevant details: Hazards: It can easily lead to carbon buildup inside the engine. Reasons: The fuel injector pressure in a gasoline engine is not as high as that in a diesel engine. Therefore, when diesel is added to a gasoline engine, the injected diesel cannot be fully atomized, meaning some of it remains in liquid form. This liquid diesel is directly sprayed into the cylinder, leading to incomplete combustion, carbon buildup, and even clogging the fuel injector.
