Bought the Mrs a 2004 Mini one auto. Car has been well looked after and covered 24k. A full tank seems to yield around 230-240 miles which is surely very poor. Admittedly its used for short journeys but you'd expect it to be better than this? I can't find a receipt for new plugs in the history file though it's been for plenty of services over 11 years.

Would new plugs make much difference?

Other than that it seems the idle is quite fast at just under 1k though it shows up as normal when on BMW diagnostic laptop. Any ideas PH?

I wouldnt expect any more from it, older petrol auto running around locally is never going to be great.

I cant see why plugs would make a difference, obviously keeping it up to date service wise and checking tyres pressures etc will all help but i dont think you'll ever get 40+ MPG out of it

Sounds about right. We were getting about 25mpg from our manual Cooper S.

I assume its a 1.6? If so they are not particularly economical to be honest, just having a look on the interweb it gives 32.5 mpg for urban which seems about right on your tankful. I get nearly that out of my Cooper S

The Chrysler engined ones are really poor on fuel.

That's decent mpg for them actually. My g/f had one and it barely did low 20s/200 to a tank and she drove fairly sensibly. It was a hateful thing and she was glad to get rid of it. Yours seems to be one of the better ones on fuel.

Even the manual ones were known for being bad on fuel economy. Is it the same 4-speed Chrysler gearbox that Neons used to have?

It's a 5 speed cvt box.'I think that level of economy from what it ultimately far from a fast car, is really poor. Seems at for the course though based on what I'm reading here. When did mini ditch Chrysler engines? She wants a cab and I want better mpg

They drink fuel and oil in equal measure, pretty crap engine in an otherwise decent car, we had one from brand new, it guzzled both from day one

Have you filled it brim to brim and worked it out? Or are you just filling it and running it till the light comes on? They're undér a 9 gallon capacity aren't they so I wouldn't expect more than 30 on lots of short trips?

Just brimmed it earlier.'it managed 248 miles from last full tank. I just put 47 litres in. Amazed it's so poor. I would have expected low 30's even around town.

Unless it's just the auto, it does seem low.

GF has a MINI One, 53 plate, manual, which quite easily get's mid 30's just doing short trips to work and back (sub 7 mile trips, stop-start, 30-40mph).

Certainly doesn't drink any oil either - maybe you're thinking Cooper S here?

The auto in that age of mini kills the mpg.
