I swapped from a 2000W 1.0 Yaris over to a 2004/04 1.6 Civic back in March. Since then I've been quite disappointed with the fuel consumption, getting around 35-36 on average for my normal travelling and no better than 38 even on a long run.

Is this normal for the car? I've tried looking on the Real MPG list but it doesn't go as far back as this model and I can't find any other Hondas listed which use this engine.

Normal travelling is a 5 mile commute to work with not all that much traffic along a mix of 30 / 40 / 50 roads plus trips to the shops and the odd 20 mile trip most weekends.

Over Christmas we went to London. Filled it up before I left, drove down at a steady 65 on the clock. Didn't use the car while there and filled it up at the start of the return journey, I'd got just over 38. That seems very low to me - I'd have expected nearly 50 out of the Yaris for a similar run.

Confusingly, the trip counter is also massively inaccurate. It typically shows around 42 for my normal usage and 45 for a run such as the London trip so it around 15% high. I'm surprised but don't have much experience of other cars to know if this is usual - the Yaris one was only per journey so I only got much of a check on longer runs but it seemed to tie up quite well.

I've checked tyre pressures, had a full service just before the MOT in December (which it passed).

The only minor thing is when I'm accelerating hard - for example up a slip road - it sometimes stutters a little but around 3000 rpm but other than that it seems to run very well.

I generally drive carefully with plenty of lift and coast and use of gears to slow down.

Am I just expecting too much, or is there something amiss?
