Difference between Diesel and Gas

If you’re looking to buy a truck for the first time, you’re probably wondering about the difference between diesel and gas. In the beginning, both of these fuels come from the same place; each is derived from crude oil. This unrefined oil is taken to a refinery where it’s divided into two parts: heavy and light.

The heavier oil becomes diesel fuel. Diesel fuel is dense and also less flammable; it has to be compressed at a higher pressure and temperature in order to combust. When it does combust, it does so without a spark. This means that diesel transmissions don’t need spark plugs, which makes for one less thing to worry about in diesel maintenance. The higher density also means more energy and better gas mileage as well as more power.

The lighter components of the aforementioned crude oil become gasoline. Gas is much more flammable than diesel, meaning it’s easier to start, where sometimes diesel engines have trouble starting in cold weather. Gasoline trucks have traditionally offered a little less in the way of fuel economy. But thanks to developing technology like EcoBoost engines, modern trucks can compete with diesel in that regard. We have many of both options at Tom Naquin Hub and we’re happy to help you find which will be the best for you.
