Expert insights - RTTR

  • Mobil Delvac 1™ Saves RTTR over AUD $16,600 per 1 million km
  • Iveco Truck with Detroit S60 12.7 litre ADR 70
  • Road Transport & Training Resources Pty Ltd, Queensland, Australia
  • Mobil™ customer since 1998

Objective

To ensure improved performance and overall operating cost reduction with component longevity.
 

Situation

Initially, the Detroit Series 60 engine was lubricated with a major competitor’s semi-synthetic SAE 15W-40 engine oil. RTTR (Road Transport & Training Resources Pty Ltd) management found that the downtime accrued with continual servicing with this oil contributed to the overall operating cost of running the unit – this was unacceptable.
 

Solution

Mobil Delvac 1 SAE 5W-40 fully synthetic engine oil replaced the competitor's engine oil and a 1 million kilometre trial was completed to determine operational and maintenance cost savings.
 

Result

The enhanced service life of Mobil Delvac 1 resulted in an extension of Oil Drain Interval from 40,000 km to 100,000 km – hence, a direct reduction in unit downtime and service roster and a reduction in spares inventory held. Performance gains included better cold weather starting, more rapid oil pressure rise when cold and better oil pressure when hot.
 

Benefit

Using Mobil Delvac 1, cost savings of AUD $16,600 were realised from the following:
  • No valve train adjustments required with use of Delvac 1
  • Reduction of component wear rates
  • Reduction in fuel usage
  • Reduction in servicing downtime
 
  • Mobil Delvac™ products

  • Why choose a synthetic oil?

    Your engine is a complex machine with hundreds of moving parts that operate under a wide range of temperatures and stressors. The oil you select needs to be equally capable of coping with these operating conditions to protect your engine.
