This engine has a lot of tricky stuff in it like variable geometry oil and water pumps so maybe they've cracked the emissions with economy paradigm? I've only noticed one DPF burn so if it happens every 3000km (during a very occasional highway run), it's probably not going to have a measurable impact on economy.
Oh I do run DPF cleaner every tank If you look at my fuel log there's a dip in the 5th tank where I didn't run it. It's expensive but pays for itself and claims all sort of benefits like keeping the EGR clean etc.
The only real mod I have is solar panels that ensure my battery is 100% charged every morning- that means stop start works 90% of the time with my one traffic light per km commute.
The new van averages 18.5mph, the old van only managed 16mph (lifetime) matching NEDC's city speed. The new van is faster on paper but I generally don't drive it faster, so I think I've gotten better at avoiding the real trouble spots over the years.
I sit up really high - it gives me almost supernatural traffic anticipatory skills. With a throttle less 1.6 and 2+ tons I have next to no engine braking (you feel no difference when you put the clutch in!) so I use a LOT of DFCO. So much in fact that my thermostat never opens fully - new European cars seem to be set up that way for whatever reason.
