The average car on UK roads is around seven years old, and over that time it’s likely that deposits will have built up in the vehicle’s engine, reducing efficiency and increasing emissions.
This can be minimised by using premium fuels (we’ve seen the evidence ourselves after using Shell’s V-Power petrol) but there’s also the option of using a fuel additive.
These consist of small bottles of chemical magic that users pour into their vehicle’s tank before filling, or part-filling, with fuel. Despite being around for decades, the public is still sceptical about the promises made by such products – lower emissions, better fuel economy, and so on.
Premium fuels already include these additives, but in a bid to prove its own product does a better job, Cataclean recently teamed up with fleet management firm ARI and the RAC to conduct an extensive test.
Using a fleet of five diesel-fuelled Peugeot Partner vans in London, the study recorded the untreated emissions and fuel consumption over a four-week period. The same vehicles were then treated with Cataclean and subjected to a further four-week test under similar stop-start driving conditions and mileages.
The study concluded that NOx emissions dropped by 16%, CO emissions fell by 24% and hydrocarbons were reduced by 32%. Fuel economy also improved by 9.7% while the estimated service life of the van’s diesel particulate filters was increased by 1,344 miles to 124,224 miles.
While we’ve been unable to perform our own testing, a search of the internet finds many reviews both positive and negative, and that’s the same across the entire additive market. However, the ARI and RAC’s findings are compelling, and will be attractive to any fleet manager.
