V Power is 98 octane and Ultimate is 97 Octane over here in the UK.

Around town I get average 21mpg (imperial mpg) and on the Motorways 26mpg (imperial). Car has only cover a 1000 miles.:thumbup:

And something else,i drove the car in snow conditions without chains
and i didnt have any problem,the x drive didnt engage at all.The only thing was at 5 kilometres/h when braking very gently the car was slipping.The road surface wasnt icy just fresh snow.

comes on and also i think you can hear or sense it,like the abs when engaged.

Well, the instant fuel consumption reading while idling is never accurate because when you are not moving, you are infinitely consuming fuel. The instant fuel consumption simply shows 30l/100km as a base reading when you are stopped.

To view instant consumption, you may dive into the hidden on-board computer functions. Start with the vehicle off, key out.

1. With your left hand, hold the S/R button in the instrument panel, while turning the key to position 1. The OBC will read "test __"

2. At this point, keep pushing the S/R button until you reach "19._". Then, it will alternate between on and off. When it shows off, push the S/R button until it shows "4._"

3. After a second or so, it should show "4.0 _ _ _ _ _ ". You may start the vehicle at this point. Numbers should show up in the blanks as you accelerate. This is instant fuel consumption. "136" translates to 13.6 l/100km. Note that with a cold engine, fuel consumption is substantially higher.

4. Under light acceleration, fuel consumption should spike at the beginning, around 50-80 l/100km, and it should steadily decrease. At highway speeds on a flat gradient, it should be between 6-11 l/100km cruising at 100km/h.

5. When you coast and let off the throttle at anything above 50km/h, the consumption should drop to 0 (and the thing should read "000"). This applies to manual transmission vehicles and '07+ X3s with the newer automatic transmission with earlier torque converter lock up.
