I have a 2010 Holden Captiva diesel and I was wondering what would be the best additive to use for my DPF filter?
Answered by CarsGuide
21 Apr 2022DPF additives are real thing right now as consumers run scared over the thought of their car’s DPF needing replacement. These additives use a catalyst that claims to help clean out the DPF and regenerate it, usually by lowering the temperature at which the soot will be burned off in the filter.
Perhaps some do, but just as surely some of these will be snake oil. Choose a known brand and be prepared for the experiment to be a complete dud. Expect to pay about $30 for a bottle of additive, too, so it’s not a cheap experiment.
You can try either the type of additive that is simply poured into the fuel tank when you refuel next, or the type that is sprayed into the air intake system with the engine running. Either way, these are probably best regarded as a preventative measure and the servicing industry seems pretty doubtful about the additives’ ability to clean a DPF that is already blocked.
