While the majority of cars have gas-powered engines, many cars rely on diesel fuel. If yours is one of them, you will want to make regular maintenance a top priority for your car and its diesel engine. Though diesel vehicles are known for having fewer problems in general than gas-powered vehicles, that doesn’t mean they are maintenance-free. To keep your car running as long as possible, make these maintenance tips a part of your regular routine.
Use the Best Fuel
As you may have found out early on after purchasing your diesel-powered car, there is diesel fuel, and then there is good diesel fuel. Thus, when you pull into the gas station, always try to fill up with the best fuel option available. Also, always try to keep your tank completely full when filling up, since this can also be easier on your engine. By using top-grade fuel, you’ll have less wear and tear on your fuel injectors.
Cool Down Your Turbocharger
Once you arrive at your destination, it is always recommended you allow your engine’s turbocharger to cool down for a minimum of 20 seconds by running it in neutral. If you have just finished a long drive, you may want to give your turbocharger up to two minutes to completely cool down. This will help maintain your common rail injectors and keep you from spending hundreds or thousands of dollars on a new turbocharger, which are known for being very expensive.
Lay off the Accelerator
While you are driving your diesel-powered car, don’t have a lead foot on your car’s accelerator. While this doesn’t mean you have to drive way under the speed limit, it does mean you should keep your RPM in a medium range. By doing so, you reduce the risk of damaging not only your turbocharger, but also the dual mass flywheel that protects your gearbox.
Replace Your Filters
Last but not least, make it a top priority to replace your diesel engine’s filters regularly. Since these engines use specific types of filters to help reduce emissions, failing to change filters will lead to an overheated engine and damaged filters, all of which will result in a very high repair bill.
Since every diesel engine is a bit different and can vary based on its manufacturer as well as the type of car you own and its age, it is vital you stay ahead of your vehicle’s maintenance needs to avoid unexpected and costly repairs.
