Battle of Diesel vs. Gas (Fuel Efficiency, Performance, and Maintenance)

Battle of Diesel vs. Gas (Fuel Efficiency, Performance, and Maintenance)

Today, we will go over the primary differences between diesel- and gas-powered vehicles on the aspects of fuel efficiency, performance, and maintenance costs. To understand the pros and cons of both, you must understand how both engines differ.    In gas-powered vehicles with combustion engines, a mixture of gas and air is drawn to the engine, and the air gets compressed by the piston. A blend of air and gas gets fired by a spark plug and forces the piston to back down. When the piston springs up again, it forces out the exhaust, and the process starts over again. Diesel engines work similarly, but only air is drawn into the engine when the piston falls. When the piston rises back up, it compresses the air to a smaller size. Diesel vehicles don't require spark plugs to ignite the process.   Fuel Efficiency and Performance of Diesel vs. Gas In a battle between diesel and gas, diesel is the undisputed winner of fuel economy against non-hybrid gas vehicles.
