What to know about your diesel engine

Both diesel and petrol engines need to be cleaned regularly in order to avoid major damage and poor performance. However, an interesting thing to note is that diesel engines are far less prone to developing unclean buildups than petrol engines. If an engine has unclean buildups, it can cause your engine to lose power, not start-up as it should, produce an awful sound while running, consume a large amount of fuel, and yield a lot of exhaust smoke. It is important that your diesel engine is regularly cleaned and that you keep up-to-date with all of the maintenance checks it needs.
