MPG computer

[Big_daddy]

Hey ppl, as most of are aware, my leon does not have an mpg computer as its a early model.
So what option are there for me to get a MPG display? so i know what my car does ona daily run.

Without a computer - there isn't one...

However, the best way to tell is this:

Fill up (completely)
Reset the mile thing (is it an odometer?)
Do your 450 miles (Ok, I've got a TDi so I am actually bragging)
Fill up again (completely)
Take note of how many miles you've done

Note the number of litres you've filled up with and multiply it by 0.22 (to convert to gallons)
Then it's a simple case of Miles divided by Gallons, e.g. 150 miles, 2.2 Gallons = 68.18mpg

Nice and simple like.

Or use a spreadsheet that will work it all out for you (I've got one so if you want it, PM me and I'll mail it to you)

the MPG computers on the cars lie through their teeeeeeeeeth!

Yep - hence the calculations above.

The sheet I've got will plot out your average MPG in a pretty chart over time.

Yes, I need to get out more....

I think most of us who don't have TDi's would prefer not to know the mpg figures

True - I suspect that single figures would just make you cry

450 per tank would make me cry! Thats pathetic

Was thinking of getting a OBD gadget such as scan gauge, thats shows MPG but does car need to have the computer to show it.

I had a mpg computer on my audi a3 1.8T found it usefull, when trying to keep a steady mpg, but with my leon, i have nothing so i just boot it

450 between fillups at any rate - I reckon I could get 500 but I don't like warning lights

Reckon I need a remap though - but the Leon's going in the new year for something **sigh** sensible

I just noticed, it also reads fault codes. Has anyone got one of these things? Does it work?

Not at all, i just drive at the speed limit and use cruise control where possible. Also find my car is more powerfull and more economical on a certain fuel and additive mixture over any other fuel, so with that combination i get good MPG.
Booting it around can see me get as low as 550>580-ish
