APPLICATION: Cummins short-haul truck engines

KEY EDGE: Shell Rotella T5 10W-30



Red truck and White truck


This transport company was running a large fleet of trucks with Cummins engines. It wanted to assess which oil would deliver improved fuel economy and bring down its total cost of ownership.


The Shell Lubricants team recommended Shell Rotella T5 10W-30 and carried out two 30 day trials to demonstrate operational gains. Data was gathered daily in this strictly controlled trial and achieved a 95% confidence level.


Benefits in addition to greater fuel efficiency included improved wear protection, better cold temperature operation, improved battery life and extended oil drain intervals.

White truck on road


Based on a 1.3% improvement in fuel economy, across the 6,000-truck fleet, the company identified estimated annual savings of US$2,156,000.

The savings indicated are specific to the calculation date and mentioned site. These calculations may vary from site to site and from time to time, depending on, for example, the application, the operating conditions, the current products being used, the condition of the equipment and the maintenance practices.
