Hmm

approx €1.23 per litre X 4.55 = €5.59 per gallon approx

40/ 5.59 = 7.15 gallons

600 km = 600x5/8 = 375 mls

375 mls / 7.15 gallons = 52.44 per gallon.

And unless I got my maths all wrong in my first post or this one I am getting in or around the same figure

Be my guest if you want to prove me wrong.:D

€1.23/ litre x 4.54 = €5.584/gallon better still instead of going to the trouble of doing this sum next time you fill up just take note of the litre reading on the pump and divide reading by 4.54 saves doing a second sum;)

40/5.584 = 7.16 gallons

600km x .621 = 372.6 miles

372.6 miles/7.16 gallons = 52.03 mpg

Not much but your calculation is out by 0.41 mpg;)

Recently did a couple of brim to brim runs, and I'm getting between 37 and 40 mpg out of my 1.3 fiesta. Thought it might have been a bit higher, but maybe the motorway driving has made the mpg take a hit.

49.6 mpg

Audi A3 2.0TDI Quattro

(That's averaged over the last 1100 miles)

Getting around 37-38mpg out of my mx5 1.6 over the last few fills.

2004 Mazda 6 1.8L - According the the on board computer it averages 14.6 litres/100 miles. I worked that out at about 31/32MPG. Mostly driving through Dublin.

Motorway driving (assuming no major traffic) should raise your MPG, not lower it.

Think your mpg is closer to 19.3

Alfa 156 1.8TS, getting about 38mpg with about 50/50 motorway/town driving.

Usually yes, but not in smaller cars it seems. Ive seen low-mid 30s when Im doing all motorway driving, versus high 30s bordering on 40 when im doing extra urban (ie dual carraigeway driving @55-60 mph, versus motorway driving doing 80-85mph)

00 Subaru Impreza 1.6 (Front Wheel Drive)

35MPG (lots of fun) - 42MPG (Calm Driving)

Also depends on weather conditions & where I get the petrol.

It's 14.6L/100 miles not km.

You gave me a bit of a scare there, I was already thinking about changing to some hatchback 1.2L diesel that does about 4,000,000 MPG.

EDIT:

I've looked into that and there's a 1.2L diesel VW Polo which does 80MPG. Road tax would be €104/year. But I'm not going to go down that road.

I recently highmiled(emptied the boot, put extra 3 psi into tyres and kepts revs under or around 2 1/2, changed gears rapidly etc...) on this car that i own. averaged over 980miles at 41mpg!!! Thought it was good. But not worth the effort. Great car...gonna miss it a lot....but going for the diesel....octavia 1.9tdi 90bhp.:(

Eoin · 31-03-2011 11:03am

I'm getting about 45MPG in a 1.9 diesel. Mostly motorway/dual carriageway driving. Get just under 50mpg on a longer drive.

What type car?

EPM · 31-03-2011 11:28am

Consistently averaging 40-41 mpg in a 2 litre diesel. That's 80% motorway (slightly over limit) and 20% around town. If I got rid of the town driving it would probably bring it up to about 45 as that's what I got when I brimmed it from half full after a couple of motorway drives.

joolsveer · 31-03-2011 11:31am

I getting an average of 50mpg in an Impreza diesel. That is mostly suburban and motorway driving.

cursai · 31-03-2011 11:33am

Friend of mine claims he gets 700miles per tank out of his audi a3 2003 1.9tdi. Must be around 65mpg. Can that be right?

garhjw · 31-03-2011 11:35am

i have a 2005 clk kompressor and average about 33mpg. On long motor way runs, it has gone up to 41mpg.

Same for me in a 170 bhp 2.0 Quattro CR Diesel. That's driving at speeds of between 70 and 80 mph for about two thirds of the journey. If I drive at an in and around an even 70 mph for 80% of the journey I average 44 mpg.

Yeah, the 170 PDs do better by all accounts. A few people working with me have the 140s and 1000km to a tank isn't unheard of. One has a 140 PD and the other a CR and it's the PD doing better there too.

Have a 05 525d and at most get 30mpg.Drops to low 20's around town.

Wow!!! i would have thought the beamers would get a lot more than that even if it is 2.5d:eek:

merc3ps · 31-03-2011 11:55am

72-75mpg average. Best for a trip was 89mpg.
1st Gen Honda Insight.

voxpop · 31-03-2011 11:56am

1.9PD A4 - using fuelly.com to keep track of brim-to-brim mpg

Got 38mpg initially
Fixed fuel temp sensor (broken wire) - Got 43mpg
Fixed stuck open thermostat and looking at 45+ mpg at next fillup going by trip

60% M50 and the rest suburbs

My old 523i was getting 30mpg on the same journey

I doubt it. I would imagine his tank would hold around 65L of diesel which is 14.5 gallons. So 700 miles / 14.5 = 50mpg. That is pretty efficient. My 2.0TDi Audi A4 180BPH is giving me 43mpg. If I drove like my sister then this could almost reach 50mpg I'd say.

I thought so! Hes being trying to put down my Mazda for years. i beat him on the servicing...about 90€ per year. had it for five yr now and NEVER needed a new part.
When i get my NEW 04 octavia ill have him beat good!

Buck · 31-03-2011 12:24pm

07 Ford Mondeo 1.8L TDCI

54mpg (I putting in roughly 52 litres for 1000kms)

Although the trip computer shows 4.9L/100km which is roughly 57mpg

Elessar · 31-03-2011 12:35pm

2001 BMW 320ci 2.2L petrol, 6 cylinder.

24MPG, 100% urban driving. I pump about 22 litres of petrol (at about €33) each week and that gets me 100 miles.

I've been debating selling the car or scraping it under the govt. scrappage deal and getting a new, smaller motor (like a golf 1.4). But recently I'm thinking I'll keep it seeing as it works just fine and I would be paying infinitely more money to buy a new car!

Still doesn't get rid of the desire though :pac:

How many MPG?
