DPF aditives?
Lately I've seen a lot of commercials about DPF aditives that go in the tank and they're surposed to take (better) care of DPF, especially for engines that get a lot of city (short) runs.
Are they worth it? Or do they do more damage than good? Or are they like a version of holy water for the car?

The DPF is a physical filter catching particles, so unless the additive can change the principles of combustion I don’t see how it can do much.
I suppose if it could raise the exhaust gas temperature it would make the DPF more effective on short runs. But that requires additional energy from somewhere and not many liquids are more energy dense than hydrocarbons...

I believe they lower the combustion temp of the soot...

I'm just hesitant because I see all the companies that make additives talking about it, but I don't see any independant reports, test or anything anywhere. Surely if a thing helps to keep your DPF from dying at 100 to lasting over 200 then it would be tested, known, and recommended by many, not just the people who make it?

Whenever I purchase a new car I always stick a double shot of redex injector cleaner through it and always have. Often you can smell the crap burning off and it does improve pick up etc etc. I have run all my cars to circa 150,000 without issue and periodically shove a redex through it.
To me these things, sold by reputable firms do work. I have not actually used anything on the XC90 so far but I would if I get it required it. |

We sell several but to be honest the only one I can say I have seen direct results of is the Millers as that is used by staff here.
Repetitive short journeys are the usual culprit for DPF's starting to clog up. Or incorrect oil. https://www.opieoils.co.uk/p-79253-m...generator.aspx Cheers, Guy

Millers is the only brand i would use too however i stick to premium fuel (Vpower and similar) and when not locked down i have a 70 mile fast daily commute which helps. So far never had any EGR or DPF issues on any high mileage diesel.

Below is taken from Honest John's column in the Telegraph.
Wizard for Merlin I read an advert for FTC tablets, which claim to improve economy and performance while reducing emissions. Any thoughts? AO These things were used to help the Merlin engines of Spitfires run on low-grade Russian fuel during the Second World War. All fuel is better than it was then. And if you want a car to run properly, use superior grades rather than sticking pellets in your fuel tank.

some earlier ford engined models from 2005 to 2009 used an additive tank which is topped up every 36000 miles ... the very late models from 2018 use adblue additive
