@MrMoody - I know this lady at work who drives a Volkswagen car that runs on diesel. I didn’t actually think that they had any cars that ran on diesel. I thought only trucks did that.
Anyway, she told me that the main reason she went with diesel is that it’s more fuel efficient and that the engine lasts longer. After reading this article I can see why. The oil o ring from the diesel engine does a better job of protecting it from overheating, which will ensure that it lasts longer.
