Variable Size Petrol Tank?

[Albatross]

My '99 GS300 is acting rather unpredictably. When the petrol light comes on I should have about 10 litres (50 miles+). Quite randomly I have been running out of fuel after 4, 20, 45 miles, etc. :duh: :duh:

I've had the tank drained and checked for water, etc. - nothing.

Anybody know what's going on?

Its getting a bit frustrating running out at odd times!

My light comes on with about 12-15 litres left.

Has it just started doing this?

If your petrol gauge works like mine it doesn't actually sense the level in the tank very often but just drops according to how much Petrol the computer "thinks" has been used.

Your car may be using slightly more than the computer thinks - i'm not sure what mechanical problem could cause this, leaky injector maybe?
