Much and a lot simpler that I expectedpitrack_1 wrote:Much cheaper than a new DPF!!!
I'm guessing it won't be long before electric cars take over, so the fossil fueled cars will die offpitrack_1 wrote:Sooner or later people were going to come up with a solution (sorry, bad pun) to the problem. After all it's just a matter of 'cleaning' so you just need the appropriate chemical /method to remove the 'gunk' and leave the substrate behind. Sounds like there might be a business opportunity there
Maybe the market here is to make Subaru EE20 DPFs with removable sections???pitrack_1 wrote:Must be said the truck DPFs are much easier as they are simple cans designed to come apart for cleaning.
Yeah, these would be good to try but I'm going to try this european method first and see how that goespitrack_1 wrote:Ahem, just by chance found this link to an Oz DPF cleaning chemical supplier- Bluechem. Found 'em previously but somehow they didn't show up in my recent searches.
Probably easier to just use these products in your fuel tankpitrack_1 wrote:And I think there are ways to clean the DPF without removing it- you remove a port (or drill a hole), inject/spray the solution, wait then reseal and run the car. Ahem (again!), found the videos- Liqui-Moly "Diesel Particulate Filter Purge" and Wurth Australia "Wurth Diesel Particulate Filter Cleaner", both on youtube.
Most likely and yeah, when we brought the new Outback last year the dealership made us sign a form saying that would make sure the car travelled so many kms per day to allow the DPF soot to burn off. My wife drives 110kms a day, so all is good therepitrack_1 wrote:I think the manufacturer's requirements were drummed up (and live) in the manufacturer's lab/test zone. Then the real world intervenes...fuel isn't perfect, car can't live on freeway at 100km/h all the time, servicing isn't ideal, driving style isn't ideal, car gets started and stopped, EGR/other bits clog up, etc.
I think this would be the best and easiest solution for most people but definitely wouldn't rely on this. I'd still take the car for a highway run at least once a weekpitrack_1 wrote:Also you could perhaps try one of the tank additives that is meant to reduce the combustion temp fo the soot- this might help with the normal driving.
