Short communication : Comparison Evaluation of Distribution Engine Oils in Korea

Young Kwan Lim

Abstract

Domestic vehicle companies have been selling genuine engine oils with higher price than that of the same grade of regular engine oils. In this study, our group investigated the properties of engine oils for 14 kinds of the genuine and equivalent regular engine oil (KS product) species under a fresh as well as used condition recovered after 10,000 km driving. From analytic results, genuine engine oils had similar physical properties to regular engine oils under the fresh condition. But recovered regular engine oils had better properties in lubricity, kinematic viscosity and acid number change than those of recovered genuine engine oils.

국내 유통 엔진오일 품질비교 연구

임영관,정충섭

초록

국내 자동차사는 순정엔진오일을 정해놓고 일반엔진오일보다 높은 가격으로 판매하고 있다. 본 연구에서는 국내 순정엔진오일 14종과 동급의 일반엔진오일(KS제품) 14종에 대하여 품질비교 및 차량을 이용하여 10,000 km씩 주행한 뒤, 회수된 엔진오일의 물성을 분석하였다. 분석 결과, 사용하지 않은 신유는 순정엔진오일과 일반 엔진오일의 품질이 대동소이하였지만, 오히려 주행 후 회수된 일반엔진오일은 순정엔진오일에 비해 윤활성이 우수하였으며, 동점도와 전산가 변화가 작은 것으로 나타났다.
