Mamut Peru SAC, a Peruvian mining contractor, lubricates the heavy-duty engines in its entire fleet of Actros Mercedes Benz trucks with Mobil Delvac MXTM 15W-40 heavy-duty diesel engine oil. The company maintained oil drain intervals of 10,000 km before experiencing increased production and demand for more equipment availability. Due to this, Mamut Peru SAC began to seek alternative methods to improve its equipment availability while simultaneously reducing operating costs.


Mamut Peru SAC worked with ExxonMobil engineers, in collaboration with Nor Oil, an authorized ExxonMobil distributor, to identify optimal oil drain intervals for its fleet of trucks. After conducting Mobil ServSM Lubricant Analysis, ExxonMobil engineers recommended the continued use of Mobil Delvac MXTM 15W-40 engine oil while extending its oil drain intervals dramatically.

The engineers also recommended the implementation of a routine oil analysis program in order to continuously monitor the life of its oil and equipment.


The use of Mobil Delvac MXTM 15W-40 heavy-duty diesel engine oil, as well as the implementation of routine Mobil Serv Lubricant Analysis, has helped Mamut Peru SAC extend its fleet oil drain intervals by 100% to 20,000 km.

In addition, Mamut Peru SAC has experienced increased equipment availability, reduced operational and labor costs, and less waste oil disposal. These benefits have resulted in a company-estimated annual savings of more than US $96,209.
