Reserve tank woes

[renault12ts]

As far as I know, there isn't a reserve tank, or even reserve fuel. There's just a tank, and fuel.

It's not like the old days of Triumph 2000's where you pulled a knob to use fuel from the reserve tank. The expressions are all virtual these days.

Correct, but the light (known as the reserve) comes on usually with 2 gallons in the tank.

It's not the most accurate system...so you learn your car and where it will run out.

I have driven down to 0 gallons / 0 miles remaining a few times (with a petrol station in sight!) - it tends to be highly accurate. I know I can reliably do at least 30 miles when the light comes on.

It's the same with me, although seeing it at 0 miles and knowing there's a big thirsty V8 under the bonnet makes me worry more than in a smaller car, although at least they wouldn't be as much of a nightmare to start again as diesels are!!.
