Killed the DPF in a works hybrid Mitsubishi Fuso Canter 7.5t
only done 8771 miles...
If you're in the market for one, don't bother. They're shit
is that in a Falkens on an omega sort of way, or just shit at everything? 
Shit at everything

Basically a high payload 3.5t, with an 80% box body, with barn doors and an afterthought tail lift which isn't large enough to manoeuvre a full size pallet on

and because the taillift is an after thought, there's a 12"x 6" hole where the door catches are, so you can never get a pump truck cleanly onto it...
Then some ejit in Japan thought that it would be a cracking idea to fit a 100l tank to summat that has the worlds slippiest, most indecisive slushbox, ever fitted to anything. I drove from Chichester to Lewes and back today, used 1/3 tank of fuel. 14mpg from a hybrid with DPF

To put that into perspective, I have managed an overall MPG of 14.3 from a V reg Volvo 18t, with nearly 100 times the mileage on it

So to answer your question...
It's shit. Properly, totally and undisputably shit.
