What’s your best MPG?

[nevsummer]

I must have owned 30 cars but I’ve never come across MPG quite like my 18 year old Skoda Fabia 1.2

on my way home from work last night I got 62.6 MPG, over 33 miles averaging 42 MPH

Can’t quite believe it! I’m so happy 😀 

Is this normal? What do your Skoda’s do?

54mpg over a full tank in my 200+ bhp 2005 Fabia, iirc averaging around 68mph

Best full tank average on our 1.2/12v is a shade under 52mpg, long-term cumulative average over last ten years is 42.

 

@nevsummer have you ever checked your brake servo vacuum hose for splits at the junctions of the hard plastic sections with the non-return valve.  Possibility that your car is running lean.  Do you have any means of scanning for fault codes?

51 on a really good run last summer, four up with our various paraphernalia. Sitting about 41/42 at the moment as a weekly average since I do a lot of driving in traffic. Also a 1.2 12v.

I use fuelly.com to record fuel purchases.

 

Best recorded was a full tank through on motorways travelling at 'lorry speed' with wind behind

Sounds like a good thing but actually indicates something's wrong.

Is it an AZQ  or BME engine code?

It's an engine code from a scan with VCDS-Lite, not sure whether its a AZQ or BME engine  (3 cylinder, 1.2, 12V,  2004, Skoda Fabia Estate)

Have a look at that servo hose, and look at the sticker in the spare wheel well or service book for your engine code.

P0171 is 'too lean' fault code I think, so most likely a vacuum leak somewhere. 

See if there's a little port/vent on the top rim of the PCV valve near the oil filler cap.  Stick a finger over it with engine running and see if anything changes.

How many miles on the car?
