No, not in that it seems to go down too quickly, but that it goes up!



Yesterday my tank was nearly empty, but I judged I had enough to get to work and back (about 70 miles). It was about half way between 1/4 and empty when I set out. On the way in to work the gauge was going down as normal and then about 10 miles before I got to work it started to go up! It went to nearer 1/4. Buy the time I got to work it was just above empty again. Same on the way back. Showed just above empty to start with then half way home rose to 1/8 then later fell back to below empty close to home. All travelling was on either M-way, dual carriage way or A roads. Steady driving and no sharp bends to make the fuel slosh too much.



Any idea why this happens? How do the sender units work?

Makes trying to judge range a bit difficult. When I filled up I could only get 44 L in so there must have been another 6 still in the tank (MY95 model / 50 L tank).


As a side note I managed to get 32 mpg out of it since last Friday

32 MPG? Fookin' 'ell... It's Gordon Lightfoot!

(Apologies to non-crumblies)

...Or a badly failing MAF sensor...

GM, have you really got wild roses rambling about in your garage? Aren't the thorns a problem?

Dont trust the gauges.....

Mine WRX01 only uses half a tank to cover approx 200 miles.

After fully filling the tank, and covering 200mls the gauge needle points exactly at half a tank.

Then you get approx 50 miles for the other half.

They lie.

I'm try to see what the best mpg I could get is. The last week I've been crusing on the m-ways at 60-70 and hardly touching the trottle on moving off. I *hope* this is the reason . Normal driving I get 27-28. Cars in for a service today. Should I ask them to check the MAF sensor?

yoza,

I've found that too...
