As an automotive expert with years of experience in the industry, I can tell you that diesel fuel is not a universal fit for all cars. The compatibility of a vehicle with diesel fuel depends on its engine design and fuel system. Diesel engines and gasoline engines are fundamentally different in terms of their operation and the type of fuel they require.

Diesel engines are designed to operate on diesel fuel, which is a heavier, less volatile fuel compared to gasoline. They have a compression ignition system where the fuel is injected into the combustion chamber under high pressure and ignites due to the high temperature from the compressed air. Diesel engines typically have higher torque and are more efficient in terms of fuel consumption over long distances.

On the other hand, gasoline engines are designed to run on gasoline, which is a lighter, more volatile fuel. These engines use a spark ignition system where the fuel is mixed with air and ignited by a spark plug. Gasoline engines are generally more responsive and suitable for vehicles that require quick acceleration.

Using diesel fuel in a gasoline engine can lead to serious problems. As you mentioned, if diesel fuel ends up in a gasoline tank, the car may run for a short distance until the remaining gasoline in the fuel line is consumed. Once that happens, the engine will shut down because gasoline engines cannot combust diesel fuel effectively. This can lead to engine damage and potentially costly repairs.

Moreover, the fuel system components of gasoline engines, such as fuel pumps and injectors, are not designed to handle the viscosity and lubricity of diesel fuel. This can cause these components to fail prematurely. Additionally, the fuel lines and seals in gasoline engines are not compatible with diesel, which can lead to leaks and other issues.

It's also important to note that modern vehicles are equipped with sensors and computer systems that are programmed to work with specific types of fuel. Using the wrong fuel can cause these systems to malfunction, leading to a range of problems from poor performance to complete engine failure.

In conclusion, while diesel fuel has its advantages, it is not suitable for use in any car. It is crucial to use the correct type of fuel for your vehicle as specified by the manufacturer to ensure optimal performance and avoid costly damage.

When diesel fuel does end up in a gasoline tank, the car will run for a few miles or so, until all the gasoline that's still in the fuel line gets used up. At that point, the engine will shut down -- boom. Gasoline engines cannot combust diesel fuel, so the car would stop running.Jan 26, 2016read more >>
