What's the thought out there about trip meters?
I usually zero the trip every time i fill up.
Have seen some comments about not zeroing the trip as it could affect the reading of your MPG.
Does starting from zero each time give the computer a false start or should i just leave the trip to keep recording?
I am averaging 26/28 as most of my mileage is local with some long runs.
Tomorrow i have a 120 mile round trip, mainly on motorway.
Should i just leave the trip or start from zero? Really want to see in excess of 30mpg. Jim A

Dunno not zeroed mine in ages.

never bother with mine, I presume you mean the one under the mileage ? Or the other one which I would reset at every fill up.

Mixed driving, car shows 35.1 mpg at the moment, which is a surprise. Must be the warmer weather down here. . . 2017 SEAT Ateca 4drive 2.0 xcellence (May 2022 -

MY 2012 on has three trip meters Trip A Trip B and auto

On auto tells you MPG avarage speed Etc and zeros when ignition is turned off.

Trip A records the same but you have to zero it yourself.

Trip B records as above and will continue to record even if you zero trip A so giving you a complete breakdown of what you are doing.

I zero mine if I fill it for a long journey, but don't bother if I'm only doing local trips, with £25 top ups each week.

We drove from Cornwall to Sussex over Easter, where it returned a pleasant 37 MPG. 2009 Rimini Red SE TD4. Soon to be sold.

I leave mine on auto which shows each journey. Towing the caravan on Monday it was showing 21 🤪
On a relaxed motorway trip yesterday it was showing 39.
The A and B trips are around 33 - 34 which is probably realistic.
Not brilliant with current fuel prices but I console myself that I only have an 18 mile round trip commute to work these days. Landrover - turning owners into mechanics since 1948

On my ancient 2007 GS when I zero the trip the mpg is also reset. It takes about 35 miles before I get a believable mpg and I understand that the computer then displays the average for the last 35 miles or so. I just use it as an indicator and use an app to calculate actual mpg, which is currently over 33mpg over 76000 miles travelled.

Thanks for all and prompt replies.
Didn't know about auto.
Tomorrow i will set both to zero for the day.

You will get ever increasing rounding errors.

I simply started jotting down the data on the back of the receipt when we fill up, only takes a brief moment. Started when I first got this car & have been doing it ever since.

I don't do it the see how efficiently we are driving. It was more about how much we were spending on holidays as a whole, especially when we do 15,000km on a short trip. Procrastination, mankind's greatest labour saving device!

Can I say that I have a spreadsheet for all my fuel purchases.
Always fill to brim and record mileage.
First car with an mpg readout and I enjoy watching the figures.my last fill up gave me 27.45 mpg.
Hoping for better. After 17 years on zDisco 1 and 2 27 is good. Jim A

Well, best figures so far.
110.3. Miles. 37.6 mpg.
Fuel figures would have been better but for being stuck in local road works which too 8 minutes to get through.
Then a 4 mile crawl on the M8 homeward bound.
90% on motorway.
