Diesel engines are more complicated than a gasoline engine. They rely entirely on their fuel system to operate. They don't have an ignition system like a traditional gas engine does. Because of these things above, they have to be serviced differently than a regular gasoline engine. Fuel and air filters should be replaced every 15,000 miles. Have a diesel fuel injection service done every 30,000-miles. Our team of professionals at Armstead Automotive Repair has extensive experience in maintaining and repairing Power Stroke, Duramax, Cummins, Detroit Diesel, Caterpillar, Mercedes Benz and more.
