Guys,

I seem to be getting about 550 miles out of a tank of diesel on my 2001 2.2 dCi Grand Espace - I was just wondering if this is normal.

Also, how long can I go on reserve; since the fuel-pump-icon shows up? Does the sign change once I'm getting close to running out or is the icon there permanently visible switching between icon and "service"... ?

Thanks! Loving the car so far Smiley  Cool

550 miles out of a tank of diesel

our car (2002 2.2 dci The Race, 103.000km) regularly passes 1000km (620 miles) on a tank, - by which time we pour some 75-80 litres into it. 

Provided our tanks are equal size (which they of course should be) 550miles seems a bit short -  something close to 33 mpg. We get 36-37 as the norm. But then again, thats within 12% so maybe its just topology and driving style ?

I have a good measurement of 300 km strictly 125 km/h (GPS) steady (sort of boring) motorway-driving with a constant speed - where our car apparently did just over 15 km/l  (42 mpg) - which probably is as good as it gets.  This is derived from the notoriously inaccurate tripcomputer, corrected with the knowledge of how much diesel I pour into the tank etc.

Driving 90 km/h will probably make it slightly better, but changing speed is the costly part. Seen from a fuel-economy viewpoint, it just doesn't like queues/traffic.


Also, how long can I go on reserve
dunno, - and since its a diesel, I haven't been so brave to actually find out - so we fill it up either before or just after it reminds us to.

I think it is normally 5 liters, i.e. 40 miles or so?

Thanks Lennart. I think the last tank ended up at 580 miles, but this one a bit shorter. I'm probably getting a bit used to the car meaning that I'll probably drive it a tad more aggressively - which I should stop of course. I'm also commuting through some horrible traffic from time to time, sometimes only crawling at 20-40mph (A34 north of Oxford). I'm sure I'll get better economy out of it if I'd run a bit more continious motorway speeds without acceleration/slowing down.

I asked about the reserve because, just as you mention; it's a diesel, I don't want to experience running out! Smiley

Thanks again!  Smiley

Is that the one towards the north-east, which passes Silverstone ? - or is that A43 ?

I recently had my dose of UK traffic when I naively thought I could drive from Reading in the morning traffic, and arrive in Dover in good time ... HA HAHA - silly me!  -  it took us the best part of 4 hours (!) - but we got to see Windsor Castle, as we attempted to cut the troubled M4/M25 corner.  As it happened, half of Berkshire had decided to do the same.  :-)

The A43 goes past Silverstone - my previous commute route - which is much better... A34 is one junction down on the M40 then towards Oxford.....

UK traffic is generally silly...  Roll Eyes

As I've actually run my 24v out  of  petrol I can tell you that the gauge goes to 0 orange bars and then cheekily goes back to 1 bar shortly before running dry!  I can't remember how long it went on  the -1 bar for but I think 0 bars is equivalent to about 5 litres.

Thanks Will! Hope running out didn't cause too many problems! Smiley

Espace, because it's worth it!

I once did 50 miles in my 2.2dCi Grand after the last bar had gone out and when I filled up it took 79.8 litres. According to the specifications it has an 80 litre tank capacity.... Needless to say I haven't pushed my luck that far again.

In my experience 550/580 miles on a tank is OK for commuting in UK traffic. Mine quite often does less than 500 on a tank when used solely for local running but then I've also had 680 miles when motorway driving.

That's excellent info Martin! Smiley I've done some 40 miles I think - but unfortunately I went for the pay-at-pump at Tesco this time which mean that I was only able to fill up with £60 worth of sludge...  So I couldn't tell a) how much I could get in, b) what my MPG was...  Undecided

Next time... Smiley

My wife saw me parked beside the road as she drove past but didn't think...so I persuaded her to come back and collect me (but only because I had our 4 year old with me!) . I was able to cycle back to the car with 5 litres so we soon got going again.
