  • Use of premium fuel system cleaning product Cataclean reduces emissions by an average of 24% and improves fuel economy by almost 10% in fleet management company ARI study, conducted with the RAC
  • Real-life, four-week test on 2016 Peugeot Partner HDI vans at work in London
  • DPF (diesel particulate filter) regeneration cycle also improved
  • Emissions and fuel consumption recorded pre-treatment and post treatment under typical urban-driving conditions

 In February and March this year, fleet management company ARI, commissioned a study for one of their customers undertaking infrastructure work in and around London. The study recorded the emissions and fuel consumption data of five untreated 2016-registered Peugeot Partner HDI vans over a four-week period, under real-life conditions. The same vehicles were then treated with premium fuel system cleaning product Cataclean and analysed for a further four-week period where they were driven under the same typical stop-start driving conditions. The mileage covered in both periods was 6,800 miles.

Test results:

  • NOx emissions were reduced by 16 per cent
  • Carbon monoxide was reduced by 24 per cent
  • Hydrocarbons were reduced by 32 per cent
  • Fuel economy was improved by 9.7 per cent
  • Fewer DPF regenerations
  • DPF service life increased by 1,344 miles to 124,224 miles.

Based on 10,000 annual mileage, a fleet of 400 diesel vans such as the one in the ARI study could save in excess of £70,000 in the first year on fuel saving alone by using Cataclean, even taking into account the cost of the Cataclean treatments. Such a fleet would also benefit from reducing the number of DPF regenerations and the subsequent reduction in downtime as well as emissions, resulting in lower maintenance costs.

“At a time when policy-makers, businesses and consumers are looking for wins to address the very present dangers of pollution from diesel vehicles in our cities, we hope these findings come as positive news. Fleets and individual motorists can trust in Cataclean for their petrol, diesel or hybrid vehicles – from superminis to HGVs and motorcycles – and genuinely do their bit for the environment as well as their pockets,” says Graham Fraser, corporate development director at Cataclean Global Ltd.

“ARI is constantly looking at ways to improve the performance of its customers’ fleet and benefit the bottom line. We’re obsessed with data!” commented Matt Cranny, operations director at ARI. “We were keen to put Cataclean to the test on the streets of London and are convinced by the results. Besides the impressive fuel economy and emissions performance, the van drivers in the study reported improved drivability, claiming that the vehicles seemed more responsive and that they noticed they did not fill up as much.”

Motorists can purchase Cataclean in 500 ml bottles for their petrol, diesel or hybrid cars, and motorcycles, from many retailers including Halfords and other auto stores. It is also available online at

ARI and Cataclean continue to work together and are extending the testing to 40 or more vehicles over the next two to three months with the continued support of the RAC.

About Cataclean

Developed in 1995, Liverpool-based Cataclean is the flagship product of System Products UK. Cataclean successfully holds patents for and supplies global markets in Europe, Asia, Africa, Middle East & the Americas. The product is a fuel system cleaner for diesel, petrol and hybrid engines. Cataclean markets its products through established distributors in the motor trade and is available at retail and industry level.

How Cataclean works

Cataclean protects and maintains the catalytic converter, reduces emissions, improves fuel economy and restores performance; Cataclean Diesel offers these benefits in addition to reducing the risk of diesel particulate filter clogging. Cataclean contains solvents that break down deposits in fuel delivery systems formed by oxidation and polymerisation of hydrocarbon. When Cataclean combusts, it forms carboxylic acids, aldehydes and active peroxy compounds. When these compounds reach the exhaust vapours, they clean inside the catalytic converter, removing carbonaceous deposits from the surface of the core. The result is an increase in the catalyst’s ability to remove harmful exhaust emissions such as carbon monoxide and nitrogen oxides.

Cataclean’s process also has an immediate effect on engine performance by cleaning and rejuvenating the fuel systems, injectors and valves, and optimising the combination and ignition of the fuel mixture. The result is better throttle response and improved fuel consumption.
