Ran out of fuel in the pit lane??

I'm currently in a race, I started the final lap with 4 litres of fuel whilst using about 3.8 litres per lap!
Both my drivers or on exactly the same strategy and push levels, one of drivers ran out of fuel actualy at the pit box, is this a bug? If not its rediculous that this can actually happen!!!!

When I say final lap, I should of said final lap of that particular stint

Can somebody look into this please Race ID 72527

if you post a screenshot of this

Or even look it will show you how much fuel you had at the start of the lap, also could depend on push level, and where your pit box is, in relation to the start/finish line

Thanks for your reply David, I'm not sure how to do screen shots but I have checked the amount of fuel heading into the final lap of that stint and it states 3.8 litres.
I clearly remember checking as my drivers crossed the line heading into the final lap of the stint and it stated 4 litres.
I've just checked for both my drivers and they both apparently had 3.8 litres left heading into the final lap of that stint and yet only the one driver DNF'd as a result of fuel.

For reference my pit box was before the start/finish line.
I appreciate that not alot can be done now it's just frustrating when you spend time working strategy and calculating fuel loads for this to happen.

You had a little bit less than 3.8 litres of fuel left. Depending on your push amount in the last lap that probably result in what you experienced.

Thanks for looking at that Nico, its a shame that .00601 litre of fuel can cause a DNF especially while actualy sat at the pit box but I guess thats racing!!

That's racing and we all learn from that. Just add 1L more than you need and you'll be fine.
