Question: What Happens If You Put Diesel In A Gas Engine?

Will diesel ruin a gas engine?

What happens if you put diesel fuel in a gasoline engine?

Since diesel fuel is thicker and denser than gasoline, the fuel pump will struggle to move the diesel/gasoline mixture through the system. Instead, it will clog up the fuel filter. And whatever amount of diesel that then makes its way to the engine will clog the fuel injectors, making them inoperable.
