CU2 Auto, 1000km on 1 tank

[buddah51au]

My CU2 which was delivered around five months ago in March 09 is stuck at around 10.4L/100Km according to the reading. Occasionally it dips to 10.3L/100Km but that's rare.

buddah51au - what's your opinion then on the BP98 Ultimate fuel - supposedly they give you better kilometres and keeps your engine clean?

Personal opinion only is that I wouldn't spend the extra. It is designed to run on 95RON, so use it, just stick with known companies & you shouldn't go wrong. As for better economy, I have tried in the past & found no difference.

I have seen no evidence that BP98 helps to keep the fuel system cleaner & if there is an improvement in economy I believe it would be so minuscule you wouldn't notice it.

I think I have proven in the 3 years I have been on this forum that if you stick with the recommended RON fuel, drive conservatively, & the conditions are right you can achieve better economy without driving like a tortoise.

These are good figures but why are people so surprised? My dad used to drive a 2001 V6 2.8 litre VW Passat that would get 6.2 on the highway every day. 5 speed auto.

Even my heavy last car the Ford FG Turbo with 270kw was 7.5 on the highway. 6 speed auto.

98 RON can give you slightly better economy, but not enough to offset the extra cost per tank for 98 over 95 if you go by $ per km.

I use BP Ultimate 98 because it burns really clean, so practically no soot on the exhaust pipes.

I think most of us live in the suburbs and we are lucky if we ever see our fuel consumption in single digits.

I tried to copy my spreadsheet here, see if it works. I think you should disregard the first tank of fuel as it is obvious the dealer didn't completely fill the tank. But this is how I keep my records For total accuracy. as the car had 25km on it when i took delivery you need to deduct 25km from total milage for all readings. The blank spaces next to a milage figure are my oil change & filter recordings, or in the case of the first 3 blanks, accessories purchased.

The lowest I got with the trip comp is 6.7L/100km, cruisng at mostly 80~90kmh@6th gear to Blue Mountain. I tried to get 6.6L/100km doing 80kmh but didnt manage. Manage to get around 800km on a full tank with a few days of town driving mixed in. Mine is stock CL9

I was getting about 9l/100kms on a real good day with my CL9.
I now get 7's with ease, same driving style, with the heavier CU2 that makes more power....

p.s. What happened to the shit box ford???

Hi buddy. As the country highway driving last time I did, my CL9 can do 6.8L / 100km as well. I believe that the cruise control may help to reduce fuel consumption.

nice

My brother's CU2 manual gets around 670-700km / tank
Sydney traffic

There are 2 sides to using cruise control. Yes, it certainly helps on flat roads, but on the other hand it uses more fuel on hilly roads. If your looking for economy the ideal thing to do would be to use it on the flat roads, but turn it off at other times.

Congratulations Buddah51au, very impressive figures for the CU2. I have a CL9 auto and just passed the 60,000 km mark. My average figure is 7.39 l/100km from new, with my best of 6.295 l/100km. I fill with 95 RON of all brands including many times with ethenol blends. I set the cruise on the speed limit. The greatest majority of driving is in the country and at 100 kph. I do visit Sydney and up to the Blue Mountains (family) every 6 to 8 weeks or so. So I do get a bit of 'trafic' from the end of the F3 to Katoomba. I keep my original Dunlop tyres at 33 psi, the car is bog standard.

Absolutely I agree with you. Thus I memtioned before using cruise control on country highway, that is flat road. In fact, I dont want to active cruise control on hill ways, bit dangerous, especially on sharp turns.
