Diesel Injector Cleaner Case Study
Helping heavy truck and road freight operators go further on a full tank of fuel
Comprehensive testing has confirmed Ampol Amplify Diesel Injector Cleaner can increase heavy vehicle fuel efficiency by up to 12%.
Working in the road transport industry means you play an import role in the life of all Australians by helping to keep the wheels of the nation turning. Constantly working in tough Australian conditions means the demands faced by heavy vehicle and long range freight operators can also be unrelenting and equally unforgiving.
Large trucks, semi-trailers and road trains are expected to keep going the distance, at times under extreme weather, over uneven road surfaces and often in remote and inhospitable areas.
To help keep your mighty machines going the distance and operating at their very best, Ampol has developed Amplify Diesel Injector Cleaner concentrate, now available in 300ml or 1 litre plastic bottles to add to directly into diesel tanks.
It’s specifically formulated to ensure the injectors in your truck engines remain as clean as possible to help keep them performing with maximum efficiency.
At Ampol, we develop and test our formulations under the harshest Australian conditions. So to confirm the efficacy of this advanced product, we conducted a comprehensive 6-week testing program under real life road and work conditions.
LR Hotshots is an Australian owned company based in Wangara WA who agreed to trial Amplify Diesel Injector Cleaner in their Isuzu fleet.
The company provides 24/7 emergency freight services throughout Western Australia’s remote locations including Pilbara, Kimberley, Gascoyne, Midwest & Goldfields.
The aim of the trial was to prove to superior performance of the latest deposit control additive technology – quaternized polyisobutylene, in Ampol’s new Amplify Diesel Injector Cleaner. This is based on the deposit control technology used in our new and third generation of Ampol Premium Diesel fuels ‐ Amplify Diesel and Amplify Diesel HD.6 modern Isuzu trucks were chosen for the trial.
All fitted with a high pressure common rail injection system and also meeting the following criteria:
- Odometer reading over 200,000 kms.
- Already running on Regular (unadditised) Diesel and not using any other fuel additive.
- No Injector Cleaner used prior to establishing the baseline data.
For the trial the following criteria applied:
- Each truck fitted with 2 or 4 x 200L fuel tanks and each tank then dosed with Amplify Diesel Injector Cleaner.
- Trucks used Regular (unadditised) Diesel before and after Amplify Diesel Injector Cleaner.
- Fuel filters were replaced and tyres were inspected before commencing the trial.
- No oil change was carried out during the trial.
- Trucks were used by the same 6 driver(s) who shared the vehicles and followed typical Pilbara routes from Perth.
For truck details, see the table below.
The LR Hotshots Maintenance Supervisor initially gathered baseline data from each vehicle before the trail commenced including weekly ECU downloads as well as:
- Fuel consumption (L/100km) from truck logs and admin records.
- Fuel Injection compensation for each of the 6 injectors from each truck.
Upon commencing the trial, the results were regularly monitored to confirm the efficiency improvements generated by the Amplify Diesel Injector Cleaner after it was added to the fuel tanks.
The final measurement on fuel consumption data was obtained as per baseline for each vehicle. Data was gathered once the Amplify Diesel Injector Cleaner was consumed and for approx. 20,000 km.
The trial result confirmed a reduction in fuel consumption as a result of clean injectors.
|No.||Make/Model||Engine Serial Number|
|LR11||ISUZU FRR 110-260||6HK1690529
|LR23||ISUZU FRR 110-260
|LR30||ISUZU FRR 600
|LR31||ISUZU FRR 600
|LR33||ISUZU FTR 900
The results confirmed the superior performance of Amplify Diesel Injector Cleaner in delivering cleaner injectors and a corresponding improvement in fuel efficiency.
The Bottom Line
Clean injectors after treatment with Amplify Diesel Injector Cleaner produced an improvement of up to 12% in fuel efficiency with an average improvement of 8%.
Apart from reduced running costs, the superior engine performance also helped deliver sustained reliability across the LR Hotshots test fleet.
“There’s no denying Amplify Diesel Injector Cleaner works. I’ll be rolling it out across my fleet for improved efficiency and reliability.” - Proprietor, LR Hotshots
