When it comes to choosing a new vehicle, shoppers have a lot to consider. They have to decide whether they want a sedan, coupe, convertible or station wagon or if they prefer the tall driving position and off-road and foul weather capabilities of an SUV or crossover vehicle. Another important factor is what type of fuel they want to use. In addition to the usual choices of regular, mid-grade or premium gasoline, many now have the option of diesel or gaseous bi-fuel vehicles. Both diesel and gasoline start as crude oil that is mined from underground reservoirs before being refined into different types of fuel. From there, the engine converts the fuel into mechanical energy that turns the wheels of your car. While gasoline does this job with a string of quick explosions, diesel engines achieve the same result with much larger and longer chain reactions.

As a result, diesel engines tend to produce more power and have better fuel economy than gasoline ones. Diesel fuel is also thicker and heavier than gasoline, so it takes more time for it to evaporate inside the engine. This helps to keep the internal components lubricated, which decreases engine wear and tear. A drawback of diesel fuel is that it is more expensive than gasoline due to the fact that both federal and state governments impose taxes on it. In addition, the diesel engine requires a specific fuel additive to help reduce the amount of sludge produced by the combustion process. When deciding between a diesel and a gasoline powered vehicle, it is important to consider your lifestyle and driving habits.

If you do not travel long distances and tend to stop frequently for groceries or errands, then a gasoline vehicle is likely to meet your needs. However, if you do drive a lot of miles or haul heavy cargo, a diesel might be the right choice for you. If you aren’t sure what kind of fuel your vehicle is designed to use, check the little door on the side of your car that houses access to the fuel tank. It will usually say ‘Gasoline Only,’ ‘Diesel Only’ or ‘Premium Diesel Only’. If you fill up with the wrong kind of fuel, it could damage your engine and cause costly repairs.

If you fill up with the wrong type of fuel, it is important to not turn on your engine. Gasoline engines are not made to combust diesel fuel, so doing so will prevent the engine from starting. Putting even a couple of gallons of diesel fuel in a gasoline engine can lead to serious and irreversible damage. If this happens, it is best to call a tow truck and have your car towed to an automotive center before it is turned on again.
