Okay, so I've been filled up with 95 so now we wait. Had 1/3 of a tank left. Have noticed some difference as 100KM of driving and I use up 4 or 5 bars of the fuel guage as opposed to like 6 or 7 bars last time. Currently at 190KM and haven't reached mid point yet, two bars to go till mid point. This is very significant as I'd be under mid point at around 200KM and down to 1 bar at 350KM. I'll report back accordingly after another few "fill ups".
