Just looking on this forum over the years a lot of people take the MPG that their car tells them as being gospel.

In reality we know that this is rarely the case.

Put yourself in Skoda's shoes...

"Lad's, make sure the OBC over reads by at least 5mpg, that way word will spread that our cars are more fuel efficient than they actually are."

45 - 33 = 12

That's one hell of an over-read :(

My 170pd shows an average of 48-51 on the computer. Did you have funny up in sunny Carlisle? I hope you had good reason for coming up here!

It was a pick-up, brief stop, and return

Was about 7 hours actual time door-to-door, set off about 9.30am, back home at 4.30pm

Ah cool, long day for you. It's a nice little place Carlisle, shame you didn't get longer to have a look around

We have been around it once - it rained, family went shopping, and I paid my £1 to take photos in the cathedral - we were quite impressed by what we saw though

If the computer is over reading then I dread to think what my R is actually doing. It showed 23mpg on a 60+ mile mainly country road jaunt today. Worth every penny though.

It does tend to rain in carlisle on occasion.

I recently done a 400 mile round trip down near Nottingham and back, I've done in several times.

My thoughts are the octavia is quite a streamlined car and it's less the speed and more the hills and road surface that affect mpg. The M6 has a pretty rough road surface.

Going by the M6 then I think the a50? I can use almost a full tank what with the inclines and a bit of sitting in traffic.

Whereas going across the a66 then down the a1/m1 which is a much smoother and flatter road I can finish with a 1/4 tank of fuel.

I tend to sit at 80 going by my satnav, giving it light throttle to keep it at that speed when needed.

Cruise control tends to give me poor mpg too, i imagine it's best suited for places like the Netherlands.

Just got my best ever mpg of 54.62 out of the last tank of derv in my pd Scout, not bad realy.

That's helpful :-(

On our cr170 superb the mfd averages 42-44mpg which is about right , on a long trip like our summer holidays to France we can get 49mpg fill to fill sitting at a steady 80mph but the mfd is claiming 52-54mpg

My first point of call would be the air filter , I find they don't last anything like Skoda say and performance is effected after 10,000 miles , I have a k&n in mine (and my previous pd vrs ) and give it a clean every 10k

My 2 yr old CR VRs was showing 57mpg on runs from Wales to Birmingham however my new Blackline which has 3K miles on it is struggling to get near 50mpg. I know the cold weather doesn't help but its a sharp difference seeing as they are the same car.

I'll look at that - I have a K&N so asked them not to change the filter at service, but they left a new one in the car - it may be ready for a clean

New engines never give great economy you'll need 10k on it I expect until it loosens

mine has done 14k now and although sure fluid change will free it up a bit but 40-45mph seems the norm and dont drive it that nice lol

Motorway seems to be 45-50 but not done a slow steady run to get much more - seem to be seeing about 500miles to a tank so about what I expect

Towing the race car it still get high 30's to 40mpg which is just what I need

From cold giving it a work out on a short 10-15mile trip to work returns about 35-38

Taking into account the real world mpg very happy for the size / weight of the car (estate) and oem tow bar add a touch more weight

I am used to seeing about 20mpg previously from my cars and finally had to accept derv was the way forward

:rofl: :rofl:

Its all the heavy gold you have on it!

Might be worth giving the filter a clean and oil, but that does seem low.

Just travelled up north for the week fully loaded and storage box on the back, done over 300 miles and still have over a half tank.

Any loss of power? Maybe the weather isn't helping

I managed 42 mpg (calculated) on my last tank doing a mix of country roads and town driving with no motorway driving at all. Also had a few enthusiastic bits of driving (all legal) and bursts off roundabouts.

Birmingham to Cardiff today 55.2mpg.

My remapped CR140 DSG (Yeti) maxidot was 10% out, so Gizzmo kindly adjusted it so that is is pretty close the the actual now.

My last tankful I managed to scrape 370 miles out of, at an average of about 35mpg. My average speed though was about 16-17mph though. :lol: that's what driving around the old smoke does for the car!!!

At about 70-75moh on the motorway it will do low 40's to the gallon. At 60-65 it will do almost 50mpg. But it is a bit of a brick.

Back to Brimna & OP. The only way to tell is to either brim to brim or use same pump and to click off. The fuel gauge does lie occasionally. :lol:

Nope CC at 76mph, couple of 5 miles sections sat at 50mph

Whatever, I'm still struggling to see the relevance of your fuel economy to my original post

I had an ECU replaced under warranty recently on my 59 plate CR vRS DSG and I think it received a software update at the same time. The reason I say this is that the Maxidot readout is almost spot on now where it was reading about 5 to 7 mpg higher than reality prior to this.

My last tankfull gave a real figure of 42.6 and the maxidot figure was 42.3. I can better this on a long run but my normal journey is 7 miles to work and 7 miles home where I'm lucky to get to 40 mpg. When it's warm and on a long run, it achieves about 45 mpg which I reckon is pretty good.

Does the maxidot not take readings from the fuel tank and use this to work out mpg?? If so a fuel leak would show up as poor mpg figures would it not??

Im gusseing this is how the trip computer works measuring actual miles driven against fuel level in the tank or is it measured another way?
