In this study, general engine oil and the Miracle top engine oil of Dongjin chemistry company were tested to find the effects to the SI engine performance. Roller dynamometer used to find maximum power, fuel consumption rate and the emission. Maximum power was measured higher when the Miracle top engine oil was used in the vehicle. By use of the Miracle top engine oil, fuel consumption rate and emission was measured lower and compression pressure was higher compared use of general engine oil. Also the Miracle top engine oil was found to decrease the engine noise at the low RPM. And after 1,500km drive at the same condition, the dust in the oil pan and oil filter was measured less when the Miracle top engine oil used compared than general engine oil used.

In Korea, sesame oil has been used as a flavor source mainly by edible oil since ancient times, and it has been used by domestic screw pressing. In the 1960's, the demand for edible oils and fats increased significantly due to the improvement of national income and changes in food consumption patterns. In the early 1970's, a few edible oil manufacturing companies with modern solvent extraction and refining plants were established. In Korea, edible oil manufacturers account for more than 85% of employees with 50 or fewer employees. In Korea, there is a very shortage of raw materials for edible oils and fats, domestic production of edible oil is decreasing year by year and import volume is continuously increasing. While importing the edible oil bearing ingredients including soybean and extracted oil in the past, recently mainly imports crude oil and refines it in Korea. Soybean oil, palm oil and tallow account for 70~90% of total imported edible oils. Due to the recent well-being trend, the demand for olive, canola and grapeseed oils as household edible oil has increased and the production of blended oil has been greatly increased. Since the late 1980's, people have recognized edible oil and fat as a food instead of seasoning ingredient and have increased their edible oil and fat intake in Korea. Since the early 2000's, refined oil and fat products produced in Korea have been exported and is increasing every year.
