If you've recently purchased a used diesel vehicle after driving gasoline vehicles most of your life, you may be wondering about the different maintenance schedules you can expect with your new-to-you car. Today's diesel engines are highly fuel-efficient, largely due to the diesel particulate filter that helps reduce harmful environmental emissions from your engine. However, over time these toxins and contaminants can build up in your filter, affecting your vehicle's fuel efficiency and causing damage to the environment.
If you have not driven your car in a long time, starting it back up may reveal a host of problems. Even after getting the engine to stay running, you may notice noisy injectors or intermittent misfires. Both of those problems point toward clogged SR20DET injector nozzles as the cause. Although you could drive your vehicle with those problems, you may notice a loss of power at high RPMs or excessive detonation in the cylinder.
