我有DESIEL 的車, VWJetta TDI. 我很喜歡，45mgp。非常省油。

diesel fuel costs highter, but you consider the mgp, it is still very cost effective. The best thing about diesel car is in its torque. It is powerful as the rpm is still low. Diesel engine is very simple and effective. It has much less parts. If you maintain it well, it can run for decades.
