FREQUENT CHALLENGES

Frequent Truck BreakdownsHigh mileage fleet clocked up to 6 million kilometres a
year and operated in harsh conditions

High Levels of Black Smoke Emissions2
Trucks were failing PUSPAKOM vehicle inspections and
regularly summoned by the Road Transport Department (JPJ)

Mounting Maintenance CostsDirty fuel injectors and failed fuel pumps needed
frequent replacement or repair

Disruptions to Delivery Schedules
Breakdowns and inspection failures caused
unplanned downtime
THE MAIN CAUSE
Regular diesel used by the trucks was causing severe corrosion and carbon deposit build-ups around the nozzles and putting great stress on the fuel pumps. This resulted in engines misfiring or stalling.
A CLEAN SOLUTION
Shell Commercial Fuels experts recommended Shell FuelSave Diesel (SFSD) with DYNAFLEX Technology1. Its exclusive dual detergent formulation can effectively clean up injector deposits and help prevent further build-ups. It is also suitable for both newer and older machineries.
WHAT GOES INTO THE ENGINE MATTERS
In 2017, Sunmaju began a 10-month on-road trial of Shell FuelSave Diesel that featured three of its Volvo FL10 trucks

THE SHELL FUELSAVE DIESEL DIFFERENCE
In 2018, based on clear evidence from the trial, the Sunmaju management team decided to power its entire fleet of trucks with Shell FuelSave Diesel instead of regular diesel.
Since the switch, Sunmaju has achieved significant cost savings3 from fewer breakdowns, reduced maintenance and higher operating efficiency. In 2020, not a single breakdown from fuel injector or fuel pump issues was recorded.
