Used Engine Oil analysis is conducted to check the current quality of oil being in use with engines. It is generally required whenever there is some malfunctioning or any harm occurred in engine and the results obtained from this test can reach the bud of the problem. Sometimes this test is only conducted to check whether lube oil is still good to continue using in engines. Through this test, we can find out if there is any mixing or additive content including water and metals, foreign particles etc.
