Nowadays, the usage of diesel engines is getting more and more common for vehicles, especially cars, heavy duty trucks and buses due to its low fuel consumption rate as compared to others. However, fuel consumption rate may be increased as a result of a long-term running and bad performance engine. Besides, the engine may keep running at a very high temperature that is over its operating temperature, this may cause the breakdown of the engine oil and thus increase the frequencies of changing engine oil. Hence, it costs more money. Here is where the problem comes. How to get the engine efficiency as good as the new one without doing any hardware modifications? The answer is engine oil. Therefore, this project is to study the effects of different engine oils and engine oil additives on the fuel consumption rate and the engine temperature of the diesel engine, Perkins 103-10. From this study, it is found that all different types of the engine oil tested greatly improve the fuel consumption rate and engine temperature, whereas Gold Engine Oil has shown the best fuel consumption rate and also the lowest operating temperature.
