ExxonMobil field engineers helped South African mining company, Stefanutti Stocks (SS), save €19 000/yr on a single dump truck. The team trialled a bespoke lubrication solution that combined Mobil Delvac™ MX 15W-40 heavy-duty diesel engine oil with a used oil analysis programme. This helped increase productivity, reduce costs and enhance SS’s environmental footprint.

SS identified lubricants as a potential means to improve operational efficiency. The company called in ExxonMobil’s Field Engineering Services (FES) team, which conducted a three month oil drain interval study using Mobil ServSM Lubricant Analysis, a state-of-the-art used oil analysis service.

Following the trial, the FES team suggested switching SS’s Komatsu HD 465 rigid dump truck to Mobil Delvac MX 15W-40, an advanced heavy-duty diesel engine oil.

The change-over extended oil drain intervals from 250 - 1000 operating hours, which cut the amount of time needed by engineers to replace oils by more than 38 hours – on a single truck. This reduced the chance of maintenance-related risks, increasing onsite safety. It also decreased SS’s environmental footprint by cutting oil consumption by more than 1000 l/yr.

“We know that our expertise, combined with the right lubrication solutions, can deliver great results, even with a single truck, and this trial has once again proved it,” said Colin Henneberry, Field Engineer at ExxonMobil. “The team at Stefanutti Stocks was great to work with and we’re excited to continue helping the company increase productivity and cut costs.”

“We are extremely proud to have been part of this trial,” said Jerome Christian, Engineering Manager at Stefanutti Stocks. “We look forward to exploring new solutions with the teams at ExxonMobil.”

Komatsu HD 465 rigid dump trucks have a nominal payload of 63 t and a load capacity of 40 m3.
