Return home following the Miller's behaving in Convoy at 70 all the way home,

Just thrashed the pants of it over to Lytham and Back and recorded another new record on the way home!

New top Mileage of 330 miles!

Record low 230!

So is 350 - 400 achievable in a cooper???

It certainly looks like it with careful driving?

400 is possible in an S Just have to drive in 6th at about 50mph

But who in their right mind would do that????

I was tempted to try a max effort until i hit a quiet M65 last night!

Well when I go down to Norfolk with the Mrs the quickest and shortest route is loads of A roads and there is not always overtaking opportunity.

Going there I get better MPG than Vicky in her Cooper

First time I went I'd done 200 miles and had 200 miles on the range left.

I came back via Birmingham on the M6 and only got 150 miles out of the 200 I supposidly I had left. Motorway speeds for you

Get anything between 220 and 280 normally out of a tank.

I had the very first customer car on Nov 28th 2001. I'm not sure when it changed to 122BHP though but I'm sure you couldn't get it on a 52 plate.

Cooper Works are very rare. 132BHP Cooper Works are extremely rare. I actually kept mine for a year while I had my S as well. I didn't want to part with it! Had to in the end though

I've done some searching on here and identified 8 members that may own a Cooper Works I'm going to PM them to confirm.

The only one I know that has a 132BHP Cooper Works is Chum Racing. Pics in his gallery.

Cheers RG! Will have to have a look at his gallery

On the air side, ambiant air temperature as well as oxygen content (less in higher elevations) is also a factor. Simply driving the same route with the exact same fuel in a +2 celcius morning and measuring it against the same drive in a +15 celcius afternoon will measurably affect both your cars performance and fuel economy.

Well, I couldn't comment on air/fuel mixtures as I don't know much about that particular side of the coin. I could look it up though...

I suppose you could record the temperatures from your trip computer at the start and end of each journey... that would somewhat standardize the results or at least put them into some sort of context for those who do know about air/fuel mixtures.

What do you think British SD?

350-400 miles should be easily achieveable if you try to drive economically and are driving in the right conditions. In theory on a flat uninterrupted road in perfect conditions you could achieve 550 miles from a standard Cooper. But you'll never find a flat road without traffic for 550 miles!

If you concentrate, including coasting downhill, then across distances without traffic you can realistically get 40mpg, but this is hard work. My record is 50mpg (measured pump to pump) over 255 miles but this was averaging 50-60mph on very flat roads and driving very lightly. However I have no problems getting less 250 miles from a tank.

I've pretty much always used Shell Optimax / V-Power and I don't think it improves the power output of a standard Cooper, but the engine feels a lot smoother when it is cold than on other standard unleaded fuels and it does feel more keen than on other 97 fuels. I've never tried Tesco 99.

Tesco99 all the way for me

Hi, how about this...

My MCS used to average about 250 miles to the tank, i use it generally...being honest, high speed motorway driving apart from about 15 mins a day sitting in traffic on the m1 just before hemel..... works out about 350 miles a week.

However, doing the same route a the same speeds since my first oil change and putting the pirreli run flat tyres on the front, (still got decent dunlops on the back) that my miles now average about 235 per tank...

This is now costing me a fortune and im considering taking it back to be checked over, but has anybody else noticed this with the pirelli tyres or even the firs oil change? I would expect it to be more efficient!

Thanks
Mike

I have 3 Dunlop RF's and One (odd) Pirelli Euphoria RF. I had an oil change 13000 miles ago and it didnt make any difference (or at least any noticeable distance) to my fuel economy

I'll add my stats to the list, as I keep a record on all my 'fleet':

2004 MC, recorded mileage today -102,069.

Average fuel consumption 37.39 mpg (7.56 l/100km), with a 'best' of 46 (drifting around France with time on my hands) and a 'worst' of 31 (in a long thrash of over 600 miles). I've always used 95, mainly from Tesco in the UK and from Leclerc in France; average fuel cost is GBP310.78 per month or 10.7 pence per mile.

During that time is has consumed 10 tyres and 2 wiper blades... I'm still running on the OE pads! As you can tell, I don't do short commutes and rarely use the brakes; this is the car I use myself. Due to the high residuals and TLCxl, this is the cheapest vehicle to run that I've had, less than a Ford Courier diesel van and cheaper than a 1.25 Zetec Fiesta that ran until 161,000.

R56 MCS arrives on Thursday but I'll run that on Tesco 99.
