“…Oil must be changed regularly to counter degradation and contamination, and to maintain the quality necessary to protect the engine. [2][3][4][5] Oil drain intervals that are too long increase the engine wear and the likelihood of engine damage, while intervals that are too short result in unnecessary preventive maintenance costs, energy wastage, and environment pollution. [6][7][8] According to the research of the United States Environment Protection Agency, one gallon of waste lubricating oil can pollute one million gallons of drinking water.…”

Although the reason is not clear, mileage is commonly recommended as an indicator to evaluate the oil drain interval of a car. This paper tries to investigate whether the mileage is the most suitable indicator to evaluate the oil drain interval based on scientific experiments and data analysis method. Three civilian cars and motor oils (contained mineral oil, semisynthetic oil, and synthetic oil) were subjected to road tests under urban traffic condition. The real-time driving parameters comprising speed, mileage, idle time, engine operation time, and number of starts were obtained by on-board diagnostic system. Synchronous oil samples were collected about every 30 days. The physicochemical properties and component changes of experimental oils were analyzed in laboratory. The effects of driving parameters on oil properties were studied with the improved grey relational analysis method. The results show that the influencing factors of driving parameters on motor oil degradation were different in different experimental cars. The influence of mileage on oil degradation was not obvious. The idle time of engine, engine operation time, and number of starts were the three most significantly influential factors on oil deterioration after comprehensive analysis of the three experimental cars.

“…Oil must be changed to counter degradation and contamination, and to maintain the quality necessary to protect the engine. [4][5][6] Large amounts of the usage and draining of engine oil increases the maintenance cost and bring great pressure to environmental protection. [7][8][9][10] According to the research of the environment protection agency (EPA, USA), one gallon of oil has the potential to contaminate one million gallons of drinking water.…”

In this study, it is tried to establish a theoretical model based on oil oxidation stability to evaluate the motor oil life. Five civilian cars and five motor oils were taken to eight road tests. The road tests contained two experiments taken in two test cars with the same car model, synthetic motor oil and test time, and three experiments taken in one test car with the same mineral oil to study the reliability and repeatability of the proposed method. The change characteristics of oxidation onset temperature, total acid number, and kinematic viscosity of test oils were analyzed. A theoretical model was established with the oxidation onset temperature and column chromatography method. The results showed the established theoretical model has the potential to quantitatively determine the remaining service time and operation mileage of the test oils with high accuracy and reliability. The test synthetic oils are able to operate approximately 11,000–13,000 km in 534–686 days in the typical urban traffic condition of China. The test mineral oils are capable of operating approximately 8200 km with 40 km/day or capable of operating 5723 km in 410 days. The proposed approach can provide some reference for end-users to drain their motor oil reasonably.

The condition of the motor oil in civilian cars is difficult to monitor; hence, we propose a method to evaluate the degree of degradation of motor oil using an on-board diagnostic (OBD) system. Three civilian cars and four motor oils (containing mineral oils and synthetic oils) were subjected to five groups of road tests under urban traffic and highway conditions. The operation information, oil service time, mileage, engine operation time, idle time of the engine, and number of start-ups of the engine were obtained using the proposed OBD system. Physiochemical properties and changes in the components of motor oils during road tests were analyzed in laboratory. The theoretical model of the comprehensive indicators of driving parameters and oil properties were established. The proposed method was successfully applied to different cars, motor oils, and operating conditions in road tests. All the theoretical models had high accuracy and precision. Herein, we provide a method to monitor the oil condition with real-time driving parameters and provide a reference for end users to change their motor oil reasonably.
