I have GSU45R AWD Grande 2007 with side steps, nudge bar, roof racks. Using Caltex fuel I was getting terrible results (even their premium) I changed to BP 95 and it is way better. Do remember that if you start / stop and wait at lights often in your drive, the econo will start to creep up. Mine is on 13.9 this morning but traffic was a bit backed up (Adelaide backed up that is) Cheers Hi Mervin, Out of curiosity, what RPM's does your engine idle at? Mine idles at just under 750rpms, which seems high, but might be totally normal.
