Diesel powered vehicles are becoming more and more popular, and today more than ever more automobile manufacturers are pumping out models with diesel options. Diesel powered vehicles are powerhouses when it comes to hauling, and they get better mileage than their gasoline counterparts. A common question asked when it comes to diesel vehicles from non-diesel owners is, “What’s the difference in how you maintain a diesel versus gasoline vehicle?” Superwash Express is happy to clarify.
Difference in Engines
It’s important to maintain any vehicle you have, whether it be diesel, gasoline, or another alternative. In order to maintain your vehicle, it’s important to understand the difference in the engines of diesel and gasoline vehicles. Both vehicles have internal combustion engines with the same concept: compression and ignition get the motor running and the vehicle power.
Where a diesel vehicle engine differs from a gasoline vehicle engine is when the ignition process begins. With a diesel vehicle, there are no spark plugs. The ignition comes from the engine producing heat by compressing oxygen and combusting. A gasoline vehicle uses spark plugs to ignite the compressed air and fuel.
Now that Superwash Express has explained the difference in the engines, it might make more sense to someone who has ever been near a diesel vehicle. They are typically louder vehicles, and are much sturdier than a gasoline vehicle. Most diesel vehicles can travel hundreds of thousands of miles, while a gasoline vehicle is not typically able to do so.
What Does This Have to Do with Maintenance?
There are going to be different maintenance practices with each of these two vehicles, as they operate differently and don’t have all of the same components. With a diesel vehicle, spark plug replacement will never be on your list of repair costs, as they don’t exist within the engine! If you own a gasoline vehicle, the spark plugs will need to be replaced, but this isn’t typically done until around 90,000 miles.
Oil changes won’t differ too much between a gasoline and a diesel vehicle, unless you frequently tow good-sized loads. If this is the case, you will want to have the oil in your diesel vehicle changed more frequently than the typically recommended 5,000 miles. With a diesel engine you will be changing the fuel filter more frequently
Perhaps the most important thing to note is the fuel type! You do not want to end up with gasoline in your diesel vehicle. The gasoline will heat up faster than the diesel fuel and cause engine damage. Not only that, but gasoline doesn’t have as much lubrication as diesel, and you may end up damaging your fuel pump and injectors.
