Average 22.5 mpg

[Simonclio1]

Hey guys my on-board trip computer is telling me my car is averaging 22.5 mpg i drive about 2 miles a days to work and back and on the weekends take it out for a spin
1.6 Clio 2004 - K&N57i kit and a cat back system which was too loud so I had a mid box fitted to it to reduce noise, how ever it is a cat back I think that what long life told me anyway ,,,,, What can be causing my trip computer to display this

Any help guys :dead:

With a 2 mile journey to work, I'm not surprised you're getting the figure you are.

Yeh but I take it out all weekend and drive further than 2 miles pal it still gives me the same reading

reset it and see how it goes.

its average over everything. if the car was hammered just after it was set for ages by a boy racer. then you will struggle to get it to rise.

Ok so could the trip computer be wrong? I hate these things rather the old school

 

[welshname]

well they arent 100% anyway. press the reset button when looking at your mpg on trip computer. (the reset button is that one on the dials) then go for a drive as normal.

If you hate it, work it out yourself.

Do you reset it every time you fill up !?

Possibility the lambda is gone/going, as that seems hilariously low unless you're bolted a supercharger to it.

2 miles a time isn't going to do any car any favours in the MPG department.. reset it, find some dual carriage way or a nice long A-road, do a few miles (10+ once the car is warm) at 50-60 and see what it thinks after that.

Thanks Guys Il reset it then take it for a blast ,,,, See what we get then !!!!
Also because i have a catback and a k&N 57i kit will this impact on the fuel results

 

[welshname]

not too much pal.

I think I had my 3.0 V6 omega down at 5mpg when I was driving 2 miles each way to work for a while lol

Not a blast... just a nice normal drive to see if its screwed or if the problem with the MPG is the throttle pedal control

Over a 25 mile jounrey in both my 1.6's I can see 40 MPG or above.

 

[Simonclio1]

Is that driving it normal or hard and is it standard pal?

 

[Simonclio1]

Anyone

 

[Knuckles]

pah! i can get 21 mpg from a 1.4... then slam it in 5th and roll down some hills and its back up into the 30's

try that? may see some rise in mpg

 

[welshname]

normal driving. not going over 3k RPM id imagine.

 

[Beef-Mc]

Is that driving it normal or hard and is it standard pal?

Average driving, through some city traffic, short DC stretch then onto A roads for the other 24 miles, through some more towns etc. Both cars were standard engine wise.
