Fuel problem

Hi Mehmet

Your last race was at the USA I believe. I'll start by trying to establish some facts.

To be out by 4L over a 75% race distance at USA, your practice laps would have had to have been out by 0.09L, this is an unusually large margin, the largest variance in a practice lap output I usually see is 0.03L


Are you able to confirm that nothing changed between you running the practice laps and the race?

The two major possibilities I can think of would be if you reduced your cars Fuel Economy by changing suppliers or perhaps ran a quick race and engines which were more worn than when you got your information.


I'll wait on your reply to rule out these factors before trying to think further on the potential cause.

Hi Mehmet.

Ok Assuming your race was online, it's just about possible that if your average push level was low then you may not have burnt about 3L less compared to push level 3.

if it was offline and you had the offline push set to neutral. It is harder to suggest what has happened.

By reverse engineering some of my calculations, for 2.2L per lap at USA you would have had a Fuel Economy rating of about 56 and would have needed 99 to 100L to finish the race if you ran the entire race at push level 3.

To burn 96L, the push could have been either "Very Low" / 1 or the FE could have been 86.


Unfortunately I have no access to your past data so it's hard for me to say much more. Next time I have a race at USA I will keep an eye on the practice laps and check if they are adding up correctly with what I would expect.
