#1: Increased fuel consumption after exhaust repaired Author: beckyjones198, Location: Birmingham - UKPosted: Sun Dec 19, 2010 7:25 am ---- Hi,
Last week I had an ongoing issue with my exhaust fixed. It was rattling and blowing and the garage said that it was just a bracket that had gone and they replaced the bit that fixes the front of the exhaust to the back bit.
Cheap fix and I was happy. However since then I have noticed that my little 206 is guzzling petrol way faster than before.
I noticed after putting £30 in my tank which filled in 3/4 full. I have been watching at as I was paranoid and its now down to half and tank and I've only done 25 miles.
On £30 I would usually get around 300 miles out of it, so in theory the 1/4 I have used should have got me 100 miles but I've only done 25. Where have the other 75 gone? Is this normal? Will it settle down?
Any thoughts would be appreciated. TIA!

Obviously!
Is the car any louder now? Are you sure the exhaust is back on properly?

I'm a girl but even I thought it wasn't good for petrol consumption to have a blowing exhaust. Could it settle down once it has worn in?

Wish I hadn't now, not only did it sound cool it was saving me money too!

Not to 70mpg. Maybe 1 or 2.
What about the above questions?

The car itself is ok I think, I am very paranoid because in the last 12 months it has been problem after problem. The only thing I have noticed is when I'm driving it seems a little sluggish as though I'm in the wrong gear for the speed I'm doing (I'm not though!) its not loud now either.
I had a quick look underneath and I cant see anything out of the ordinary.
#9: Re: Increased fuel consumption after exhaust repaired Author: beckyjones198, Location: Birmingham - UKPosted: Sun Dec 19, 2010 7:49 am ---- I forgot to add, two weeks prior to having my exhaust repaired I broke down coming off the motorway.
I was putting my foot down and barely moving anywhere. The car was almost backfiring then and had no power so I called out the RAC and they replaced something they called a coil under the bonnet.
I have a feeling this may have caused the exhaust problem, could my current problem be another side effect of this?
#10: Re: Increased fuel consumption after exhaust repaired Author: DJ-, Location: UKPosted: Sun Dec 19, 2010 7:52 am ---- What does the engine look like when its started up? not vibrating alot is it>
btw the coil thing, is the coil pack they changed

In fact, a blowing exhaust will increase fuel consumption and lower engine performance.

I've had mine show I've used up the first 1/8th tank in 20 miles but then it go back to normal/better consumption to compensate for the early incorrect measures. Just run the full lot and see how it compares. Remember your fuel consumption will likely be different to normal due to the snow and different gear/revs you'll be using. Also as petrol prices have gone up considerably recently (around 5p/litre in some places around here) if you're putting in amounts of money not litres it'll go down somewhat anyway.

Sorry I did mean that, I sort of put the words the wrong way around.. Whoops.

It happens to me sometimes,,
Mine goes up by 4 bars usually but can sometimes drop a bar in 40-50 miles then the next bar lasts 120-150 miles!!
