The distance from Nairobi to Nakuru and back is 320km so km per litre should be 19.39.
From the discussion on this forum,http://www.b15sentra.net/forums/archive/index.php/t-22515.html
Even with the fuel gauge on E, you should still make 43 km on the 2002 Nissan B15.
My guess then is that your car has a reserve of at least 20 litres in addition to the 10 litres you estimate to be left in your tank.
