What's your REAL MPG?

MuppetCheck

Just to get some idea of the variations from manufaturers figures brought up here: http://www.boards.ie/vbulletin/showthread.php?t=2057133675

Post your car, mileage, type of use.

Manufacturers figures - Your combined (properly calculated and not what your trip computer tells you).

Percentage of claimed figure

132 Astra GTC 2.0CDTi 165
21,500km on it.
50-40-10 National Road-Motorway-City driving

Manufacturers combined claim is 58mpg, my average is 46mpg (best 48, worst 39) so that equates to about 79% of claimed combined.

02 BMW E46 M3 Convertible
104,000 miles
30-30-40 (National Road-Motorway-City)

Combined MPG (Auto) - 20 mpg

Actual average MPG - 18mpg (90% of claimed MPG).

If I hit the national roads more often the MPG can go up to 25-29mpg, if it's all city it can be as low as 12-14mpg

11 VW Golf VI 1.6 TDI
115,000kms
(70-20-10) National-Motorway-City

Combined Average from my Fuelly account = 55.9 mpg (best fill was 65.4 mpg)

Manufacturer Claimed Average: 61.5 mpg

Equates to 91% of claimed figure.

This is very similar to claimed mileage from other users on honestjohn:

From what I can gather, the claimed MPG for my e46 320i was a shade under 34.9. According to the trip computer, I'm averaging 32.4, which is mostly motorway driving. Not too far off, though. If I kept rigidly to the speed limit on the motorway, I'd be over 34, I'm pretty sure.

2008 BMW 520d LCi Auto

Claimed combined - 5.6 L/100km - 50.4MPG

Actual economy - 6.0L/100km - 47.1MPG

93% actual to manufacturer figures

163,000km and counting

75-16-9 Motorway/National Road / City (ish) driving


Have exceeded manufacturer combined figures over a few days/weeks in various cars over the years. Mainly due to the 75% of my journey being 50:50 M50/M1 in more or less rush hour, so fairly constant speeds up to a max of 90-100. Traffic just doesn't allow for higher speed, so I have seen some fairly impressive MPG figures on small engine diesels.

I suppose the current daily hack figures....

1999 BMW 520i

Manufacturers figures
Urban: (I can't remember )
Extra urban: 36mpg
Combined: 31mpg

Actual: depends on situation. Normal weekday morning, mix of country roads, national roads and rush hour city traffic equates to roughly 30mpg. Popping into the town and back 27mpg. Driving up the M1 bang on the 120kmh the whole way 33mpg.

Worst was 20mpg :cool:

That's mental, had a 2001 1.4 Scenic and it did 8.1 L/100km for mixed city and country driving. Shows the difference in weight between the two models.

2005 Nissan Almera 1.5 Petrol

At the moment it's 37mpg running to and from work (Bishopstown to Little Island through the Jack Lynch Tunnel) and around the suburbs. I regularly get 45mpg when driving but the traffic at the tunnel is killing it at the moment. I regularly spend 15 minutes stopped and the car doesn't get up to temperature properly (coolant yes but oil no)

Manufacturer's figures - Not a clue and don't care.

Edit - Yes I have seen as low as 15mpg from a tank. Dont ask how......

That is bad. I get that from an 06 2.5 Kia Sorento. (mostly country roads with some towing)

air

1998 Seat Arosa 1.7SDI 173,000 miles
Averaged 4.66l/100km (60.61 mpg) last year overall. Manufacturers claimed combined is 64.2mpg so achieving approx 94% of claimed.
Hoping to improve a lot on it this year, have managed up to 80mpg on a tank (claimed extra urban figure from the manufacturer).
10% city, 30% national routes, 60% motorway.
Costs about 10c / km to run all in.

Cow **** green 2001 Volvo S40 Sport DCI (115bhp)

Manufacturer claims = 52.3 MPG

Average = 35ish on 90% motorway driving.

Haven't a clue how I'm getting less MPG than my old 2.4 156 and the Volvo is being serviced more regularly as well.

Have you all corrected your mpg to allow for your odometer being up to 10% out same as your speedo? thought not, that'll depress you all

Track mine fill to fill. Made that comment in the original post too. I'm sure it's been lost on some though:D

I tell my wife my car does 35 whereas 30 would be the indicated truth, which means in reality about 27 and then only if I behave and don't race too many Passats

might be 10% on a cable-driven one from the year of the flood, but nowhere near that inaccuracy on anything even semi-modern on sensor-driven speedos.
