Had my Dec 62 plate Exclusive AWD Auto just over one month now which has just under 3000 miles on clock (2,600 when I got it so you can see I'm a mostly bit & bob type motorist)and not yet experienced any dpf regen or even any symptoms of it so far. Been looking at various fuel additives like Wynns, Forte, Millers which all claim to clean dpf and reduce regens. Just been on Power Enhancer Uk site which recommends Archoil AR6200 fuel treatment complex as being far superior to anything else. Has anybody tried any of these additives and more importantly - do they really work? Or is it better to stick to Super Diesel (i.e. Shell - current mpg is 21-24)?
