Hi @specweapon,
I wasn't using any additives which didn't help my opinion of Subaru NZ either....
Apparently it was one of the comments/suggestions from Subaru Japan.
They've stopped importing the diesel forresters etc to NZ now I've heard, not sure if true tho.
Mainly because of the DPF filter issues which derive from not running the engine hard enough (relatively speaking) to regularly burn off the sooty bits. So the filter clogs and lights come on and owner grumps.
The burn cycle, I was told, is something like 4th gear or higher, 1800rpm to 3000rpm for 20 mins.
Around here, I'm halfway to the Waikato to achieve the 20min drive because in between are several intersections, towns etc and resultant gear changes....
Anyway, I find that staying away from 6th gear (2200rpm in 5th is ~105kph) and otherwise keeping revs around 2200rpm; not loafing to save fuel for instance, it has run sweet for some months now.
Have to say tho, that reverse is absurbly high, a bit like 2nd gear. Try doing that while backing your trailer down a tight driveway....

cheers
