Really nice find and this tells me that a car is left with a little over 2 gallons, As per my observation with most of the cars I have owned I would believe that there was little over a gallon as I could drive upto 50 Kms after the petrol light came on. However recently I just don't take a chance and fill in sometimes even before the light comes on, but recently I have to go to Baniyas Island in Abu Dhabi and with more than quarter tank remaining I passed a petrol station thinking I will get it filled in on the next pump. The next pump was not visible as my petrol light came on and I tried to drive at a constant speed lower than the road limit just to conserve fuel as I had no clue when I would get to see a petrol station again. Over 300 Kms to drive, petrol light on and not a petrol station in sight, to add to it the road was all dug up and a huge project going on. 10 Kms done after the petrol light had come on, 20 Km, 30 Kms, 40 Kms, 50 Kms and now my wife was like looking at me and cursing me for not filling up earlier. 60 Kms since the petrol light had come on and now I was getting worried as the car felt like it was going to cough up at any time, further more the challenge was to reach on time for the boat to depart in just under 2 hours with another 240 + Kms to go. Finally, it was in sight, a board that said the next petrol station was available in 2 Kms, but I could not see anything as far as my eyes could go, and due to the roads being all dug up a doubt started to set if the petrol station would still be there. Relief at last as the petrol station shone through just as the sun was setting. After filling the tank to the brim, i wiped my sweat and looked at my wife and exclaimed, It was all part of the plan, I know what I am doing, you should trust me more. I am sure my wife knew how I was thanking God deep inside for managing to survive and getting the petrol station when all hopes had diminished, but with a smile she just commented, can we move now, we need to reach there in less than 2 hours and I know its still a long way to go.
How I wish I had this information earlier, but i am sure in the situation we were in, we would be sweating it out all the same.
