help ( fuel economy )

[Richy]

hope some one can help me. i am about to order a new mini for sept delivery. but can not decide whether to get a mc or mcs. my main concearn is the fuel cost . i do mostly very short trips in town with the odd longer trip at weekends. can someone tell me what mpg. to expect using the method of full tank to empy the a re fill to get the fuel used to milage

hope you can help

PS. realy want a mcs but need aprox 30 ish mpg

Steve's only properly checked the mpg on our MCS once, on the drive down to Sheffield from Edinburgh. He got 33 then and he's guessing 26/27 mpg on short journeys

One of the (slightly) embarrassing things about the MCS is its crappy mileage figures, especially for a car its size.

Here's some reliable data from the Edmunds.com long term test of the MCS:

Current Odometer: 18,496
Best Fuel Economy: 23.7 mpg
Worst Fuel Economy: 18.4 mpg
Average Fuel Economy (over the life of the vehicle): 23.2 mpg

This matches my own mileage in driving the way you describe yours. I try to cheat by taking longer trips on weekends!

But its all worth it! Even if you have to drive it like a Prius on weekdays. (But I be you can't.)

thanx for the quick replys

are the figures us or uk galls. i understand that there is a differance.

Edmunds is a US site so it's definitely US gallons and US miles. I hope you guys have bigger gallons or shorter miles. Hawaii has a Union Jack on its flag, but is currently a suburb of Los Angeles.

UK miles are the same as UK miles -- but the Imperial gallon and US gallon are definitely different. 1 US gallon = 0.8327 UK gallon.

thanx

but how to i work out us galls into uk galls.

Math!


1 US gallon = 0.8327 UK gallon which means that 1 Imperial gallon = approximately 1.20091 US gallon


So... if a MINI gets 35 miles to a US gallon, that's that same as approximately 29 miles to a UK gallon.

35 (US mpg) *.8270 (value of a UK gallon compared to a US gallon) = 28.945 UK mpg

or

29 (UK mpg) * 1.20091 (value of a US gallon compared to a UK one) = 34.83 US mpg

Hey BruceK, I think you got it backwards. If a UK gallon is BIGGER, then you should be getting MORE miles per US gallon.

Take the US gallons and divide by .8327 (remember the decimal point) to get miles per UK gallon. So 20 miles per US gallon = 24 miles per bigger UK gallon.

Of course, I may be totally confused, but at this point no more confused than poor Richy! What the heck Richy, just go ahead and order your S, and we'll figure out the math later!

Whoops, I mean more miles per UK gallon...

I have been logging my fuel use pretty accurately and keeping a record of it.

I have attached a graph of my fuel use over a 10 month period.

The red in the line is where I was using standard unleaded. The blue line is super unleaded. All fill-ups have been using ESSO petrol.

I do a mix of country lanes, dual carriageway and about 10 minutes of sitting in traffic per day. The aircon is on about 50% of the time.

The huge blip in march was a weekend trip to cornwall. The airconditioning was on the whole time.

thanx alot for helping me

but i can still not decide does any one no what a standard mc will do will avarage air con use so i can compare between the two. at the moment i have got a 206 d turbo and get about 45 mpg so you can see why i am concerned

[SonicTPA]

Well, I decided to put some super unleaded from sainsbury's into my mc last week, as the price had come down to 80p a litre. I have been getting 350 miles from a tank normally, but this time I got 415 miles before the red light came on.

That's doing a 35 minute drive to and from work, using country lanes, dual carriage-way and in town roads. And I do take it over 4000rpm when accelerating, but I stick to below 80mph!

I always stick a couple of extra litres of petrol into the tank after the petrol pump automatically stops, as otherwise the fuel gauge doesn't indicate full. Sometimes I've got almost another 5 litres in.

If you give it a lot off oomph, the figures do start to come down quite quickly.

I went from a Pug 306 DTurbo getting around the 40MPG to a Cooper.
The Cooper with Aircon on all the time used to get 32MPG on the same Route and driving style. (a mix of local town and country road's.)
I've now got an MCS and again driving the same roads I get about 27/28MPG.
In the MCS I've had 33MPG driving like my Mum, down to 23MPG Driving like the Devil
Hope this is of some help to you.
The above were all calculated using the fill to empty method.

thanx alot everyone it has helped me alot will need to work the fig's out and make my mine up soon going of the replys i think a mc will do 32/36 mpg and an mcs 24/30 is the extra of the mcs worth it that's the big question now.
