Benefits summaryBy implementing a SignumSM oil analysis programme and switching the MV Kornett’s auxiliary engine over to Mobil Delvac 1™ 5W-40 from a mineral oil, Reederei Eicke was able to increase its vessel’s engine oil drain interval from 500 hours to more than 4,250 hours. Excluding savings related to reduced oil waste, maintenance and fuel consumption, the company was able to realise an annual lubricant cost saving of over 50 per cent.

SituationThe container shipping industry is currently facing difficult times. Due to global over-capacity freight rates are low and so it is more important than ever to keep operational costs down.

Turning to synthetic lubricants can be a smart way to increase efficiency and cost savings, by benefiting from the performance advantages they provide.

SolutionMobil Delvac 1 5W-40 is a fully synthetic, high performance, heavy duty diesel engine oil. Features such as outstanding thermal and oxidation stability minimise sludge and deposit build up, supporting long engine life, while it’s long drain capability helps owners of modern diesel engines to control costs and optimise efficiency.

Case study

Signum oil analysis uses ExxonMobil’s experience and its global database of marine equipment and engines to deliver a full spectrum of tests including asphaltene contamination detection and ferrography. These are designed to accurately analyse lubricant needs, providing bespoke reports and oil management recommendations.

ExxonMobil engineers visited the MV Kornett and undertook an engine inspection prior to the switch to Mobil Delvac 1 5W-40. From there the engineers extended the oil drain interval based on data from Signum oil analysis results and engine inspections conducted by the crew.

A switch to Mobil Delvac 1™ 5W-40 helped cut lubricant cost by over 50 per cent

Switching to Mobil Delvac 1™ 5W-40 and implementing a SignumSM oil analysis programme helped increase oil drain intervals by a factor of eight, as well as reducing waste, fuel costs and maintenance time.

Continued overleaf.

One of the limiting factors for the oil service hours in engines is the potential for diesel fuel ingress during operation. With extended oil drain intervals the likelihood of fuel agglomeration in the lube oil system increases. Therefore ExxonMobil engineers recommended a thorough oil sampling schedule to monitor fuel dilution, used oil viscosity and flash point.

ImpactBy using Mobil Delvac 1 5W-40 and Signum Oil Analysis, Reederei Eicke was able to increase the oil drain interval of the MV Kornett’s auxiliary engine by a factor of more than eight. This has led to savings in engine oil, oil waste and has increased productivity.

Off the back of these results, Reederei Eicke is now switching the auxiliary and emergency engines of its entire fleet to Mobil Delvac 1 5W-40. This is estimated to help the company save more than 50 per cent in lubricant costs per year.
