that's rather reassuring. It was exactly that type of slow-speed city driving (that is not good for regens) that you described.
Also I wouldn't worry too much about your English. Just a couple of prepositions and/or pronoun issues here and there. Even Word's grammar checker didn't pick them up.
To digress, if all Aussies had English as good as yours our standard would improve considerably. I must say the standard on Subaruforester.org is quite high... I can think of a couple of other brand forums I've been on where you wonder if the monkeys have been playing with the typewriter. I'll suggest Subaru attracts a better class of buyer!
Hahaha, thank you so much, I really appreciate your words
Talking about the blue smoke and oil smell. Do you have any wonders about it?
I don't understand why oil is in the equation of active regens.
I must say too that I never have any oil consumption. I always used Motul Eco-Clean 0W30. My Forester has now 93.000km since 16' February's and a 46% of DPF ash.
About the DPF additive cleaners I think about it many times, but I'm kind of worried because the owner's manual says that you must not add any fuel additives
