W201 low fuel light.How much left?

I consistently need to top off 44 litres when I get to the low fuel light (mileage would have been anywhere between 450km to 480km).

My Haynes manual says that my fuel tank is 60 litres.

That would mean that I have approx. 16 litres left in the tank when the low fuel light comes on.

And since my fuel mileage is about 10km+/litre, so at worse, I am looking at another 150km or so to go before it gets empty?

All you W201 owners care to chime in for comparison?

Cheers.
