Mobil Delvac 1™ 5W-40 and engineering service PetroChina Sichuan Logging Company, China, saves over $US 12,000 annually.


To ensure the fleet runs lubrication trouble-free in severe logging site operating conditions. To minimise the long-term operating costs by prolonging the engine service life and reducing operating costs.


There are 4 Chinese North-Benz 2629 trucks and 2 Perterbilt trucks in the No.1 Fleet of SLC (Sichuan Logging Company), which is one of the most important logging companies in China. The SLC fleet runs in severe logging sites in the north-west area of China. The logging site temperature is above 40°C in summer and below - 40°C in winter, often with heavy snow and rain in the plateau area. The engines frequently need to work continuously for over 60 days during the logging period.


The SLC fleet requested professional advice from Mobil and in 2003 Mobil Delvac 1 5W-40 was installed in these trucks. The Mobil Lubrication Engineers also implemented on-site technical services, including lubricant application instructions and training to improve lubrication knowledge and maintenance practices. All trucks in the fleet were monitored by a regular engine inspection service.


With professional Mobil Engineering Service and the protection from Mobil Delvac 1 5W-40, all truck engines continue to operate properly without any lubrication problems. The overall costs are significantly reduced and the production of SLC is secured and improved.


Since starting to use Mobil Delvac 1 5W-40 in 2003, a total of US$ 12,684 has been saved each year. This includes:
  • Lower diesel consumption
  • Lower lubricant and filter consumption
  • Reduced maintenance costs
