Mobil Delvac™ 1 ESP 5W-40 improves mining haul truck fuel efficiency
Improve fuel efficiency while reducing overall engine emissions
- CAT 3516 B HD EUI engine
- Taconite mine
A taconite mine utilizes 48 CAT production haul trucks that can burn in excess of 100 gallons per hour at full load. The customer worked in partnership with Mobil engineers to study how a synthetic SAE 5W-40 engine oil could improve fuel efficiency compared to a conventional SAE 15W-40 engine oil. A fuel economy study was then conducted on a CAT 3516 B HD EUI engine using an engine dynamometer and high accuracy fuel meters.
The use of Mobil Delvac 1™ ESP 5W-40 heavy-duty diesel engine oil was recommended by Mobil engineers for the mobile equipment fleet to improve fuel efficiency while simultaneously reducing overall engine emissions, as demonstrated in a CAT 3516 engine.
The recommendation was adopted by the customer to help improve the fuel efficiency of their 48 mining haul trucks by an estimated average of 1.9 per cent, representing an annual fuel savings of more than US $556,000.
In addition, the related emissions reduction was estimated using Tier IV EPA standards at more than 1,800 metric tons per year.
