Post your MPGs

The two sliproads I use regularly are both fairly steep uphill sliproads, so you still need to give it a bit of throttle unless you want to cause a huge queue and annoy everybody. Even when it's quiet you'll stop short if you just coast.

On downhill sliproads I'll happily coast in gear for the length of them.

Of course I understand carbs but the last car that was sold with carburretors was in the early 1990s.

Look under the bonnet of that capri you had restored for you.

Twin choke downdraught carb.
20mpg from Ford's specs.

You reckon you could rag it to Silverstone, make a few runs down the track, and rag it home at 33mpg.

How do you think it sounds?

And what does it matter what run you did in the Mondeo. You claim average is always 55 to 60.
Or am I right, it's just a figure you got once, on that particular run?

And if you want to drive my car fully loaded, at the speed limit, first time you need to stand on the brakes, over half a ton of kit in the back will tear through the rear seat and crush you against the wheel.
Then you couldn't pay me.

And ALL modern fuel injection systems cut off on no throttle unless your engine speed is low enough for the anti-stall to kick in.

The one on my Nissan runs at about 2.3% duty cycle if you lift off the accelerator and let it coast naturally. This is according to the Apexi Multichecker I have fitted which takes its reading from the wire that goes from the ECU to Injector #1

I tend to leave that device monitoring the duty cycle as it's the best way to gauge how much fuel it's guzzling at any given time.

2007 Astra 1.8L 140 auto 25/28 mostly on short around town trips.

2008 Nissan Murano 3.5L auto 12/15 around town, maybe 20 on a run.

I’m averaging about 53 out of an S-Max (effectively a bigger, 7 seat Mondeo), with the 2.2 and the auto, so it is achievable in a diesel one. My commute is M11/A12/A2/A205/back roads on the approach to Lewisham until I hit Norwood, although I leave home at either 5.30am or 10am, which might explain it.

The extra urban figure for your car is 48.7 so either your trip computer is wildly optimistic or your average speed for your journeys is well below the 39mph average speed used in the extra urban test.

33mpg. Just had a service - not sure it will increase this.
Alot of stop-starting on my journey.

I am amazed by all the people who calculate their MPG using the on car computer, because they are rarely correct.
My simple method, used by many others on various forums is:

Fill car to the brim.
Set trip meter to zero.
Use up the petrol
Fill car to the brim again.
Take a note of how many litres it takes to fill it.
Take note of the trip mileage.
Convert the litres to gallons - 4.547 litres to a gallon.
Then divided the miles travelled by the gallons needed to replenish the tank.
Do this every time, and you will build up an accurate picture of your true MPG.

My own car - 11 year old Ford Mondeo 1.8 petrol (Zetec Verona). The latest MPG - 34.5 (all round use)

I did this and my original 65mpg is now 70MPG. so my computer is lower than actual..?

I average 55-60MPG in my Mondeo. Did do in the 4.5 years I had the MK3 version as well.

I restored my car myself thankyou. And the original specs were not 20MPG. They weren't even 20MPG for the 3L V6. Feel free to post a link proving me wrong. The 2L Sierra used the same carburettor and engine and that did far more than 20MPG didn't it? In fact I think it might have come from one.

And no half a ton of kit wouldn't do that because unlike you, I'd make sure it was secured properly first. Not that I'd need to stand on the brakes in the first place because it seems that unlike you, I can actually drive.

The more you post with your stupid comments, the more you prove how little you actually know and how poor a driver you are.

Classic post.

And entirely predictable as well.

Another motorist that'll never make any mistake, never have anyone pull out in front of them, never have a child run out in front of them, never have to brake unexpectedly because they see everything, and can foretell everything.
Worse kind on the road, and they always cause the most accidents.
