We had no hesitation in trying this out, especially as just about everyone at Cars UK Towers has used Redex at one time or another, and were confident it was safe to use.

You can also use the DPF cleaner in conjuction with cheaper diesel as opposed to using more premium diesel fuels at each fill up. Should I Use A DPF cleaner If My Warning Light Is Not On?Yes, we will. But, to be honest, we’ll probably be misers and drop down to using it every other fill-up (which will make it cost just 2.5p per litre of diesel) and see if we notice the C-Max starting to use a bit more fuel, or be less happy when cold. The recent cold snap is what convinced our one dissenting voice, as she found the C-Max far less ‘chuggy’ on first start on cold mornings. So strike one for Redex. Has economy improved? He thought it was a great idea and favoured I buy them using my 15% staff discount rather that the Company’donated’ them so the evaluation never got done

But the one question we’ve had from a number of readers since we first started using it is: Can using Redex damage my car?Yes, absolutely. The principle behind a DPF cleaner is to act as a preventative measure to help prevent major problems manifesting themselves accompanied an expensive repair bill. Using a DPF cleaner will cause no harm and even if your DPF is only very lighly full, the cleaner will improve fuel economy and engine performance. Can I Have My DPF Removed? Update – November 2022– Interestingly, modern petrol or gasoline vehicles are now being fitted with DPF equivalent type filters. Gone are the days or buying a petrol vehicle to avoid frustrations with exhaust filter systems. Motoring product specialists such as Liqui Moly, Wynn’s and Cataclean are now producing DPF like cleaning products for petrol and gasoline cars. It’ll be interesting to observe whether PPF’s prove to be as problematic as DPF’s have been for modern Diesel engines. But as 5p a litre is about half the extra of ‘Premium’ fuel, it’s pretty cost-effective as a way of getting your fuel system to work more effectively. Strike three. Will we carry on using Redex? SparkRight claimed this device would give you ‘up to’ a 20% fuel saving! I wandered around the shop, and realised that with Platinum tipped spark plugs giving ‘up to’ 10% GTX up to 10% Redex, plus a few more, if all of them worked I’d be using no petrol at all! Redex DPF Cleaner is a specialist fuel additive that helps to keep particulate filters in diesel engines clean.
