Post your MPGs

My 54 plate 1.9tdi VW Beetle does 51.3 mpg on a normal week, that includes some 3 mile stop-starts and also some 30-50 mile round trips. I've had 64mpg on long motorway trips.

OH's 1994 1.9d t4 is currently getting approx 36mpg for combined travel which is not bad. We're hoping that increases as we start going touring in it!

2004 Fiesta 1.4 TDCi Zetec.

No trip computer, so I fill to the click, and note the mileage. Then use good old Excel.

From purchase on 1 July 2010 to the last fill up 19 March 2012, it's averaged 52.04mpg.

Fill up to fill up, the minimum is 39.34mpg and maximum is 62.33mpg, but I suspect that these may have been due to the pump clicking off too soon because I pulled the trigger to far. The fill up to fill up median is 52.52mpg.

PS. My cheapest fill ups cost me 113.9p per litre in late August and early & mid-September 2010.

I do the trip meter zero thing and always fill up to the brim. Apparently it is more MSE to go to 3/4 and save the weight but to be honest with petrol rising by the minute rather than the day it seems best to keep fuelled up.

Don't fill your fuel tank – by having a full tank of fuel, you are adding quite a lot of weight to the car. Your tank should never be more than three quarters full. This means filling up more regularly but it will make your car run more efficiently. If you do want to fill the tank, stop filling when the petrol nozzle ‘clunks' as this means you are full.

The Mercedes C200 auto on my morning commute seems to be getting about 30mpg which isn't bad for a very hefty chunk of motor I don't think. It's better than the manual 318i it replaced at least.

The bike is averaging 42mpg for the same journey and seems to do 165 miles to 18 litres no matter what.

5t.

My 2007 C1 does 52mpg on my daily run, 2.3 miles to work and 7.5 miles school run, all on slow moving 'A' country roads. Last run to Wales, round trip of 540 miles done 78mpg!

I'm now looking to buy the newer model which is even more economical.

Nissan Micra 1.0 2001. On average about 260 miles a month. Mostly local driving. 30-31 MPG. Shocking!

I might as well trade in the missus' Micra and get something substatntial after reading other people's MPG!

Just done the very thing. Used to have a rough Astra 1.7td and as I only do 250 miles a month I now have a lovely 2.0L Rover 600 with air con and all the toys. Put 44.4litres in (£60) on the 26th of February and still have enough in the tank to get me through this week. Used to spend about £40 in the same time in the Astra so the fuel bill has increased approx £20pm but the luxury and pleasure of driving is worth way more than that.
Don't know current mpg yet as haven't had to re gas but will post at some time this week after visiting local tax station.

What actual savings do you think would be made by only putting enough fuel in the tank to take it up to the halfway of three quarters tank level? If a car has a tank capacity of say 60 litres then the weight saving on a petrol car would be 22.5kg for half a tank and 11.25kg for three quarters. The figures for a diesel would be 30 and 15kg.

On a car that weighs in at 1300kg the amount of weight saved is going to be in the region of 1.7% (half tank) and 0.85% (three quarters) for a petrol car and 2.3% (half tank) and 1.15% for a diesel.

Would such negligible weight savings really make a difference?

Yes, but probably a negligible one

Do you keep the manual records as well?

Every now and again I'll make a note but its something I kind of obsess about.

Of course it has. Compare the MPG of a 1.6 or 2 litre mark 4 or 5 Cortina with a modern car with a similar sized engine. When I changed a 1986 Cavalier 1.6 to a 1993 Nissan Primera 2.0 I found that the Primera, despite having a bigger engine with 35% more power than the Cavalier, was more economical.

Indeed. I had Ford Capris for about a decade as a classic car.

In my fully restored 2L Capri with a recon engine, it had 98BHP and returned 37MPG on a run. It weighed OTTOMH 1050kg (I put it on a weighbridge at work once). Compare that to a 2L Ford Mondeo that also does 36-37MPG but has 140BHP but weighs about a third more. Put that running gear in a Ford Capri and you'd get 50MPG.
