Looking for a bit of advice here. Booked my car into a main dealer for it's MOT and asked them to collect and drop off my car from my office as it saves me time and I don't need a car during the day so a courtesy car is a waste of time.

Before the car was collected I reset the trip computer. When I got the car back, it had done 11.1 miles, which is roughly the right distance to and from the dealership. However the average mpg was 24.7. My car is a 1.6 petrol Civic, and driving carefully I can get 40-42mpg, normal driving in traffic at rush hour and the odd blast up a dual carriageway during the week gets 33-35mph. So the young lad who picked up and returned my car must really have been ragging it get it down to 24mpg!

Now the question - do I complain? I'm not happy with my car being driven hard from cold (no way it will have warmed up in 5 miles) by someone I don't know, and to get that mpg I would actually have to try bloody hard! It was a young lad that picked it up who was telling me about his S3 and I would feel guilty if he lost his job over it (not that I would probably ever find out) but I'm not entirely sure whether to ring the dealer and complain.

Were they sat in rush hour traffic? Crawling in first wouldnt do the MPG any favours.

Bear in mind that the trip computer is fairly inaccurate over short distances and that even just moving the car around at the garage can mean it's averaging single figure MPG without actually going anywhere.

PS - move on. Proving that the car has been hammered, if thats what you think, would be a headache and what would you want done to satisfactorily rectify it?

Personally, I think it would be a lot of myther for little reward, though if the car has been hammered, I sympathise.

Some of us can only dream of 24.7 mpg...

Good point. How much of the fuel would have been used with the car idling? I.e. MOT emissions test.

It won't do many mpg when its being revved up to get it warm enough for the MOT and then the emissions test, and it would have been idling for a while during the test. etc.

Basically, don't complain.

hehe True! But some of us can only dream of only dreaming of 24.7mpg...

It's made worse by the fact that I told the guy that it had a brake light out (I had only found out the previous day) and it would need to be replaced before the MOT, he didn't and so it was failed the first time. No extra charge but annoying nonetheless.

And they did'nt wash it - last time it was serviced they "washed it", returning it covered in bird st and mud on the interior. This time they didn't bother...

ETA: I hadn't thought about idling during the test...see this is why I asked before I complained!

I was just about to mention the emission test, cars are often left idling for quite a time.

There have been several similiar stories like this on PistonHeads lately and yes it is concerning, especially the ones where cars have gone in for a service or work done and they obviously have been taken home for the weekend.

I would be most annoyed at this as our cars are very personal to us and we treat them with care only for some T**T to rag them about and risk smashing them up.

My own dilema is that i have been restoring a very special car for just over 3 years now and have put in many many hours of work and need to take it in shortly for some body prep and respray which means it will have to be left with a garage for some time, something i am not to keen on and will certainly have to disable the car engine or some other way of making sure it stays in it's place.

Complain, yes i would !!

It could have been idling for 25 mintues whilst being MOT'd.

I wouldn't lose any sleep over it. If it's a problem, next year drive it there yourself and observe the test and then drive it home afterwards.

I'd go with this. The figure you're seeing doesn't prove anything.

As far as 'courtesy washes' etc go, I wouldn't bother with the main dealer any more. At least you won't be paying for extras you don't really want and only sometimes get.

I leave the cars running for most of the test, usually 35 to 45 minutes so 24mpg isn't bad.

Seriously, you'd complain because the car had done a lowish (but not terrible)mpg (verified by an inaccurate gauge) on a short journey that had a long period of sitting idle/being warmed up in between?

This is why I'm glad I don't have to deal with customers.

I have a 1.6 civic myself and routinely VTEC-yo to and from work. I've never seen the MPG drop below 32 (despite trying my best. 24MPG seems impossibly low.

Surely that's from the thing sitting stationary with the engine running while they did emissions tests and whatnot on it?

they'll have left it stationary for a while etc which will really bring the mpg down.

move on
