We’ve been testing for two months now. Our 2.2-litre Diesel Range Rover Evoque has been having the Redex treatment, and is a lot better off for it.

The Benefits of a System Clean

Redex System Cleaner helps maintain and improve the condition of your engine, and removes deposits from your fuel injectors. Harmful buildups on the injectors occur during combustion – Redex helps to eradicate this. Simply add 90ml of Redex to your fuel tank every time you top up; or, if you haven’t used a system cleaner in a while, add a double dose.

Used over time, Redex can improve both engine life and vehicle performance. You get better fuel economy, meaning you get more fuel and more miles for your money. As simple a thing as adding a bit of Redex System Cleaner to your fuel tank can save you money and hassle in the long run. The product also claims to help reduce harmful fuel emissions – so by giving your engine a good clean, you’re also helping the environment.

Redex System Cleaner – The Verdict

The car we’ve been testing the product on is 4 years old, with a mileage of just over 30,000. This meant the car probably didn’t have too much buildup on its fuel injectors. However, after just one shot of Redex, the Evoque just felt healthier, and knowing performance wasn’t being degraded over the 400 mile journey put our minds at rest.

We noticed slight increases of mileage per tank after the second and third additions of Redex. This of course can’t be definitively put down to the system cleaner, but it certainly didn’t hurt. Since our car is relatively young, the best we can expect is a 2-3% improvement in performance. For older cars, say 10 years or older, you can experience more drastic improvements as the fuel deposits will have had more of a chance to gather.

That’s not to say it’s a bad idea to use Redex on a younger car. The cleaner can keep the car operating at an optimal level – preventing buildup rather than fixing it.

The Final Say

Overall, we haven’t noticed any extreme changes using Redex over the past few months. However the idea of a system clean is still a good one, though. Redex provides preventative measures for keeping fuel tanks clean and can improve fuel economy over time. We really like the idea of using a cleaner regularly as a way of maintaining the vehicle. After all, we like to keep the bodywork clean and polished – why not the engine too?
