I've recently bought an S2000, and the bloody thing keeps stealing my petrol.

Now I'm not talking about how much it likes to drink while driving, I mean when I park up for the night. If I get home from work with 4 bars left in the tank, when I start her up in the morning I've got 2 or 3 left.

Is this normal?

It's definitely not on the road underneath, and some little tinker isn't siphoning it out, so where is it going?

Help please?

LOL
They are renowned for their crap fuel gauges.
It gets to about 1/3 full and then just plumits.
It can be different each time you get in it.
Mine does ~200 miles to a tank (it is supercharged).
So I fill up when it hits 180 miles!

Initially, fill up when (or before) the light comes on.

Then for a few weeks (probably after your first week as no doubt you'll be testing vtec a lot winkbiggrin) measure your MPG *properly* (i.e. miles vs actual amount of fuel to fill up) and do this for a while to get a representative mpg.

Now you know your mpg, and you know it's got a 11 gallon tank then you will know the real/likely range. Make sure you reset the mile gauge every time you fill up.

I get, on average, around 29mpg with mixed driving. That's 348 miles to a tank. I always think about filling up after 250 miles but not worrying (again ignore the gauge) and once up to 300 I really make sure I fill up asap.

Unless you are doing a lot of in town driving or in vtec all the time (be honest, most people aren't ALL the time) I doubt you'll get much less than 25mpg, that's still 300 miles to the tank.

Driving in France last year, I got well over 350 miles on one tank before I gave in and filled up biggrin Worst tank over there was 33mpg and best was 37mpg. Be very hard to get that sort of economy over here.

Once my Civic gets down to about a 3rd of a tank the petrol seems to just vanish.

My ITR is the opposite - it'll drop to half a tank, then to 1/4 tank, quite quickly.

So when the light comes on I fill up...to discover I've still got 2-and-a-half gallons left!!!

I have found the S2000 fuel gauge to be a strange beast, twice now I have hit traffic and I have seen 4 bars rapidly become 1, then the fuel light come, naturally I start to panic slightly but as the traffic eases I have witnesed the bars go up again, sometimes back up to 3 or 4

Its almost like it predicts that I need to fill up based on the current mpg, and once I get moving again the bars go up, odd although Im sure its just a crap gauge.

I got 32 mpg off of £30 the other day but that was mostly motorway, i then followed that with a week of going backwards and forwards to work which isnt a long drive but is mostly sitting in traffic, only got 20 mpg off of £30 of fuel.

The gauge in my MK2 CRX is useless as well it seems to just randomly pick where it wants to go and moves there.

Its rather annoying when you can get up to 40mpg out of it or under 10. I managed 1/3rd of a tank in 18 miles on Combe biggrin
