What's your WORST MPG? - craig-pd130
I'm a diesel owner, and so tend to talk about the best mpg I get (Passat PD130).

As it's winter, short cold journeys etc, and for a change, what's the WORST mpg you've had over a tankful?

I've just had 38mpg from a tankful, which is only the second sub-40mpg tankful the Passat's given in 4 years (due to short commute, cold mornings, no journey over 15 miles).

It's still over 50% better than the 23mpg my Volvo T4 gave during winter one time ....

Had a low-mileage Skoda 130 once whose original copper plug leads were past it. Once the engine got hot foot to the floor would produce jerky progress getting slower and slower. Until it got new plug leads that Skoda could easily do less than 15 mpg (normally on the road they do better than 40).

That particular car also had a porous carburettor casting that meant it couldn't run when properly adjusted, but that made very little difference to the fuel consumption. A tiny whisker of choke had been adjusted into it by a previous owner, sufficient to keep it idling with the throttle closed. Took me ages to realise the carb had to be chucked away and replaced with an older one that worked properly.

current car (3.0 auto Jag S Type) does 15.5 mpg in rush hour constantly bad traffic

rather rashly bought a V12 auto Jag XJS when I was 21........that would do 9mpg when hammered (which at 21 you do don't you) and 13-15 on a run.....which is one of the reasons i got rid...urgent

Worst in the Mondeo is 38 mpg against an average of 47 mpg. Basically it involved a trip to Fairford airshow sat in a 6 mile queue in 33°C heat with the air-con running constantly, then getting stuck in a queue on the A419 going back, and making up time on the M4 at around 90-100 mph all the way back to avoid a kicking from SWMBO.

Worst overall was 11.6 mpg average (according to the computer) over 17 miles of my favourite minor A and B-roads in a Rouse Sport 304R Sapphire RS Cosworth. The fact that the 17 miles was completed in 14 minutes had something to do with it, but what a car that was!

Cheers

having said that once went from Anglesey to Liverpool and back in a V8 Land Rover and I worked out that we did about 11mpg. Great fun though and as about 15 years ago the bill was not as bad as all that. Think that it was 160 miles there and back and we used a tank and a half.

Oh don't ask! I've seen as low as 14.7mpg according to the trip computer for a heavy dose of city centre driving and the last tank of purely suburban driving was no better than about 17mpg.

On the short commute to work, I have not had less than 40 mpg, in my current car, 2005 Mondeo 2.0 TDCi 130PS. In the past I had a 1988 Ford Granada 2.0 Ghia Efi Auto that regularly did 18 mpg and I once had a 1970 1300cc Renault 10 (manual), with Auto choke that also did 18 mpg. Both these vehicles were correctly tuned and in good condition (verifed by garage technicians)

12 mpg from a Mk2 Granny? That's quite an achievement. 16 mpg was the lowest I ever measured, although fuel computer could show miniscule figures.

Aircon = R12, nothing better, 0'C at the vents.

"12 mpg from a Mk2 Granny?"

Worth it, as it was the car that taught me that there are no substitutes for cubes. Never forgotten that. I still prefer the 30mpg I get out of the Jag.

Ref the cooler - I could get it so cold in summer that I had to turn the aircon off or I'd be shivering. Blissful.

Auto Maestro 1.6 petrol, worsened to 23mpg on a run as the needle and jet wore,
In the end I couldnt reliably make it from yorkshire to bournmouth without refueling.

I swapped it for another Maestro, a 2.000cc Perkins prima ( non turbo)
On the same run it went there AND back on a tankful....
I was amazed by that at the time, enhanced perhaps by sitting in the same cabin.

TVR Griffith - 9mpg around town. At a constant 70mph on a long run varied between 15 and 25mpg for no apparent reason.
BMW M3 - 14mpg at a constant (indicated) 230km/h with blasts up to 250km/h. 17mpg round town and up to 30mpg at a constant 130km/h with cruise control.
Jeep Grand Cherokee - 10mpg (converted from US) and never higher than 15.

I must have a very heavy right foot. I never get anything like the fuel consumption figures reported here for Mondeo TDCIs and the like when I drive them.
What's your WORST MPG? - Mchenry
I don't know exactly what my worst mpg was because the on-board fuel consumption display conldn't display it!
The vehicle was a Ford Excursion - a seriously large SUV hired in Canada: 8 full-size seats and a good-sized boot, 3100kg (I think) unladen and a 6.8l V10 to push all that around the countryside. In the interests of science, we tried to see how high we could get the consumption: with the transmission locked in 2nd accelerating up a hill the display showed --.- in other words over 99.9 litres per 100 km which is somewhere between 2 and 3 mpg.

About 37mpg in the 306TD, with lots of stop/start urban driving in cold weather and with the occasional heavy right foot when I get frustrated in traffic jams etc. Usually get around 43mpg combined and around 47/48 on sensible motorway driving.
