What did you try to do?
I partecipate in an offline league. I wasn't online during yesterday race in the russian gp. I prepared my first stint with 38L, i should have run for 14 laps (2,7L/lap).
What happened instead?
instead i did 16 laps (2,3L/lap). I had this problem for the others stints too


Did the problem happen while using wi-fi, mobile data, or both?
Wi-fi

Did the bug happen in the app, on PC, or both?
App

What is the model of your device?
Redmi note 7

What is the operating system?
Android

What is the version number of the operating system?
9

Can the bug be reproduced?
The only thing i know is that others managers in my league had the same experience

Additional comments:
This isn't a push level problem

Hi,
Did you notice strange behavior with tires too ?
Does it look similar to this bug : https://igpmanager.com/forum-thread/34883 ?

Yes, probably tyre consumption was higher too but i don't remember tyre wear i had in the practice laps

Hi,

During a race, the fuel estimate is calculated in real time based on current consumption levels.
This is not a bug, playing in an offline league also implies this, so with a default "push level" boost fuel consumption is not altered, on the contrary, you can save fuel until the car makes another lap and this alters the race strategy.

Practice laps are performed on a normal/middle push level. Even then, the predictions you see on the strategy page isn't always indicative of the fuel consumption you will see in the race. It might be lower or higher and is affected even more if you used a different push level.

Bruno i think there is a misanderstanding here... 

Practice laps indicated an average fuel consumption of 2,7L /lap. During race with a push level 3 i had around 2,3L/lap. This reduction of 15% is impossible even if i run with push level 1... Plus all others managers of the league had same problem... 
IF this is not a game problem we have been stupid yesterday in the same day and in the same league... 

This is the same issue but this guys reported only the tyre problem but he had fuel problem also

Why you pinned this thread solved? This isn't... 

Something gone wrong in the sim yesterday, or maybe is only the russian gp? I don't know but i have a google spreadsheet with my game data that i use to make strategy and i can say that a fuel consumption reduction of around 15% in all the players of the league (and maybe other leagues) is impossible...

I observed similiar issues,  mainly on the new tracks, canada is really bad, that the practice fuel consumption is different than the race consumption.
On the old tracks i have to adjust during the race for 1 liter on the new tracks sometimes 3-5 liter even when using an average push level of 3.

I've noticed that on most tracks the automatic lap calculation leave you with lots of fuel left over at the end. If you correct this calculation based on measured fuel consumption, you will run out of fuel in most cases despite spending the race on push level normal.
When you refuel, does it add the amount of fuel you select, or does it top the fuel up to that amount? My last few races suggest the latter.

I calculate the amount of fuel based my collected data, push level and practice laps consumption. Never had problems before. Plus the problem in this topic is that i had around 15% LESS consumption than practice laps... 

I don't understand your question (my english is not so good) but when i refuel 35L i have 35,0 L

Those values are indeed curious. Also the effect seems to happen only occasionally and, while perhaps more likely on new tracks not limited to them, and not limited to single tracks or teams. 
While I did notice some increase in variance it's still in line with expectations from the lowered CD power and the effectively halved value of design points which result in a starting FE well in those low regions with quite increased consumption. Your training consumption values are not that different and show a FE only very few points below mine on those tracks (Russia, China), so it's not a result of an extremely low FE like from weakness either.

You set the amount of fuel you want in the car leaving pits with, so whatever is left in the car gets topped up to the set amount. However, like it might happen with rain stopping, you can't remove fuel, so if you set an amount lower than the one already in the car the car will just leave the pit stop with the same amount it entered.
