How to maintain diesel engine?
Diesel engines require more frequent routine maintenance than gasoline engines. More frequent oil changes generally required at 3,000 miles and more frequent fuel filter and air filter changes. On the plus side however, normal gasoline engine maintenance such as replacing the spark plugs, distributor cap and rotor and replacing ignition wires are not necessary on a diesel engine. You don’t have to worry about an Ignition module or coil going bad. It’s simply because a diesel engine has no ignition system. I have a diesel and its at 92,000 miles, I have mine serviced at 8,000 mile intervals, it just keeps on going, get through flooded roads OK, too.
