LR Logistics Case Study

Ampol Amplify Diesel HD Injector Cleaner

Going 12% further on a tank of fuel thanks to clean injectors

Road transport keeps Australia moving, and the conditions are unrelenting - extreme weather, uneven road surfaces and long distances to cover. Freight providers expect their vehicles to perform, from trucks to road trains.

We put Ampol's Amplify Diesel HD Injector Cleaner to the test under real-life conditions for a remote Western Australia freight provider, proving its value in reducing fuel consumption by increasing performance.

The Mission

LR Logistics is based in Wangara, Western Australia and provides a 24/7 'Hotshot' emergency freight service to the Pilbara and northern WA. Each Ampol formulation is made to meet the harshest Australian conditions, so the wild north provided the perfect setting to trial Amplify Diesel HD Injector Cleaner in an Isuzu fleet.

New deposit control technology for the cleanest injectors

Ampol Amplify Diesel HD Injector Cleaner concentrate keeps truck engine injectors as clean as possible to optimise performance and efficiency. Ampol Premium Diesel Fuels use the latest deposit control additive technology.
 
Our mission? To prove the superior performance of this technology. We tested the difference clean injectors made to machine performance and fuel efficiency over six weeks under real road and work conditions.


The Action 

The Vehicles

LR Logistics tested six modern Isuzu trucks that:
  • Were fitted with a high-pressure common rail injection system
  • Had an odometer reading over 200,000km
  • Were already running on regular (unadditised) diesel, not using any other fuel alternative
  • Had not used an injector cleaner

The Trial

We tested these trucks over six weeks on their regular routes from Perth to the Pilbara, with the same six drivers who shared the vehicles.
LR Logistics replaced the fuel filters and inspected the tyres before the trial commenced.
Each truck’s 200L fuel tank was dosed with Amplify Diesel HD Injector Cleaner. The trucks continued to use regular (unadditised) Diesel throughout the trial. No oil changes happened during the trial (see Appendix 1).

We gathered baseline data on fuel consumption plus fuel injection compensation. As the trial progressed, we regularly monitored the ongoing fuel consumption and efficiency data. We took
readings once the Amplify Diesel HD Injector Cleaner was used and for around 20,000km after.

The Result

After using Amplify Diesel Injector Cleaner, the clean injectors showed an improvement of up to 12% fuel efficiency with an average gain of 8% across the fleet (see Appendix 2).

The Bottom Line

Clean injectors mean fuel efficiency and improved reliability - and Ampol's Amplify Diesel HD Injector Cleaner is proven to increase fuel efficiency, keeping injectors clean and engines running. The trial delivered:

  • Reduced running costs for every vehicle
  • Superior engine performance
  • Sustained fleet reliability

“There’s no denying Amplify Diesel HD Injector Cleaner works. I’ll be rolling it out across my fleet for improved efficiency
and reliability.”
