Petrol can sign and miles left

[FiatT234]

Hello,
I was wondering if any Fiat 500 drivers know how many miles are left when:
1. The lovely yellow petrol tank appear
2. When the petrol gauge measure has only 2 small bars left
.......Thank you

Most cars light up with 5L left.

Why don't you carry a gallon around and then find out for yourself? Better, wait until the 2 bars come on, then fill it and calculate by difference from the total tank volume.

Better again, don't worry about it and fill the thing when the light comes on or as it goes below 1/4.

Since these days most fuel pumps run immersed in the tank, deliver at high pressure for modern injection systems (3bar or so) and in consequence use the petrol for cooling (!) this is much the best advice for long term happiness.

Besides which, it doesn't actually change the running cost at all.

Fill it up when the light goes on, subtract the amount that goes in from the specced tank capacity, presto!

Doesn't the trip computer show how many miles you have left?

This is a good point. Add in the old advice not to run a tank empty to avoid drawing any debris into the pump, not sure how valid this is but it's a reasonable precaution, and running any car empty is mostly to be avoided. Dragging air into a fuel system can be bad news too, I've known the older diesels need the air bleeding out by a mechanic in order to run properly after this. So scratch the advice to run it empty and see.
