Hello all,
Thanks for your feedback on this issue. We appreciate that it's frustrating, so we're grateful for your patience and especially your information. We believe we are making progress on this issue from our end and hopefully will have a fix shortly. 

Thank you for the Info. Hope you can Fix that Soon and we can Race again ::smile:

So just skip fuel practice program right?

No. Just dont restart a Session (Practice or Race). If you dont restart any Session you can Play Normal also Fuel practice program.

Hello all, 
Thanks very much for your comments and feedback. I'm assisting the community team on launch weekend to help out.
We're looking into the issue you've reported with our test team and will hopefully have some sort of resolution as soon as we can. 
Thanks for your patience. 

Thank you for letting us know. Legends!

Also agree completely with Maxime10 on what is said about the conditions.

I’ve had the fuel drain issue and solved it by starting new career. I initially tried the game without patch and it seemed fine but i was earning less development points so started a 3rd career with the patch and just used flashback which I hate as apposed to restarting seshs.

i feel the fuel drains a little on the low side as I can use rich mix a fair bit but atleast i can venture thru career mode no issue.

keep up the good work CM all the best workin thru all the bugs and dealing with the at timea ungrateful community.

Ive always said the only do the beta to get the youtubers to sell the game for them I mean I havent bought the game yet for first time and from what ive read its been a good descion same bugs as last year which isnt really a surprise but u would of expected them to of had fixes in place before the even started to develop the game considering the game is an evolution of last year you wouldent expect same bugs as long as people keep buying the game on release its just going to be sameevery year I mean it isnt bad enough we get the game half way threw the season but it comes full of bugs and have to waite till the season is finished before its half fixed I think its about time someone else came in and took a shot at it even f1 its self could make the game and we could get it much earlier in the season with them already known the regs and how cars will loo

The youtubers don't even use the beta. The beta is only ever a small chunk of the game they want you to test. They use a preview build or get the final product a little early.

But someone has written, when you have the problem once, it is also on the next race. If not, I just would finish my actaul race with double fuel and gon on to China without flashback.

Thats true. If you have the Fuel Bug "started" then it stays also for ALL next Races (in my Case also in Practice). Best Solution is to Play all other Modes except Career currently. I restart my Career when the Fuel Bug is fixed.

At least i have no FPS Problems, Crashes, Freezes or Texture Problems.

Ok, I just wondering, why it only happens in the race. I just restarted FP1, and Qualifying was totally fine. Of course I restarted the race. But my understanding is, if you restart for example FP1, then all other sessions also effected. Weird bug. 
I started now carrer new. Hopefully no bug fuel bug there. I wont restart a session,

[SwissSkynet]

OK, now its getting weird....and this is not a Joke!
Started F1 2017 because 2018 Fuel Bug and what happend....I GOT THE SAME BUG NOW IN 2017! The excact same Problem. Now my Career in 2017 is also Fuel bugged but WHY? Thats extremly strange!

[kamsufc]

I started a Sauber Career Mode on 105 difficulty and for the first race I started with -6.02 laps of fuel which meant I had to conserve fuel in lean mode for 17 laps. Not sure if that was a bug or just something that Sauber has?

[XioGShep]

Did you run the fuel management program in practice? If not, then it will just put in a default amount of fuel (low in some cases), and it will be on you to check your setup and make sure enough fuel is in.

If you did run fuel management, then its how you ran the fuel management that messed with the auto calculation. I ran fuel management how I would normally race, and the game hasn't shorted me any fuel. Usually gives me an automatic 1.5-3 laps of fuel in some cases, usually averaging around 1.5-2 laps more.

[BelgiumDude]

It's the race strategy program that calculates your fuel -

I see. I’m not sure why it calculated -6 laps...

My fuel management programme was Excellent but I guess it was from rave strategy instead...

Maybe... my race strategy hasn't been great, but fuel management has been spot on, and my fuel input for start of the race is calculated spot on to where I want it. Dunno if its a combo of both, or I just keep getting lucky <_<

[Chubimandryl]

I got rid of it by restarting my career and then in Australia, failing the fuel saving program and didn't restart any session.

[YngwieReid]

Same thing happened to me... 
AI 105
Distance 25%
PC-Steam

With ers set to automatic and fuel on low, with the car fueled to max, it was not possible to save fuel. I retried with just staying in 8th gear and coasting as much as possible and it was still impossible to finish. Very disappointed 

[Hoo]

I've merged a couple of related threads on the fuel issue.

[skylinegtr34]

Sorry for my question , but i don't understand all (Sorry im italian ) this bug, if i make all session with fuel program and don't restart anything, all game it's right??, the problem it's only if i restart the race or any other session? Thank you! 

[Sherp1239]

alex172 said:

Same problem here on PC with Renault. 100% race, Australia, 15 laps to go and fuel runs out. Even driving on lean the fuel still drains so quickly.

Edit: I did notice an issue with the fuel consumption practice programme, in that it registered the average fuel consumption as 0 (something like that, wish I'd taken a screenshot now). No idea if they're connected though.

I noticed the same thing.
When i started the fuel consumption practice on Bahrain it maxed the fuel saving out before the first corner. McLaren with fuel set on MAX. Didn't even change when i started doing donuts, which in F1 2017 made it go full red in a couple of seconds.

Thank you.

Any news about the fix ?

[andygsxr750]

Same problem here with fuel usage on ps4
Think it's happening after restarting session your in or after using flashback? Frustrating 
Only started in career at Baku race and same in Spain so can no long continue career till fixed!

[skylinegtr34]

ok, now the problem it's clear, how many times need to resolve the problem?? it's impossible!

every year it's the same story!!

codemasters, now you need 2 weeks for fix this bug???!!!

my patience after a lot of year of same problem on d1 it's 0

make a fix for this problem only in few days and other minor bug later...

but the community need have information, one day or one week or what? not the silence between find bug and solve patch!

thanks!

Hi all,

We're still drilling down to try and get the best information for the development team, could I request some more information on their behalf?

Can I ask for a short video of the issue happening? Ideally just a short video showing the MFD fuel screen as well as a lap or two of the changing values. Equally, a screenshot of your R&D progress wold be useful (particularly fuel related) so we can rule out any issues there.

Thanks for your patience.

[paradizFr]

Hi,

I have the exacted same issue,
I had to restart a practice session due to big wall impact
After that, I remember that fuel consumption was null. I get weird r&d results for fuel (something like -54 for the last line and 0 for the others, I cannot check right now). I figure out that fuel consumption was null because I get a purple result in fuel session after a few corners without doing any L&C.

In the race session, I have to go with the full tank, get +13Laps on start and consume around 3 estimated Laps per lap on full mix 3, 1 estimated Lap on 2 and I can almost stay at the same level of estimation with full mix low and a lot of L&C.

Maybe I can share my profile files if you get an email?

I have the same problem with the fuel,I’m doing 25% race (15 laps) 
stsrt with full tank enough for 24 laps,by the time I’m on my 2nd lap it already says I don’t have enough fuel for the all 15 laps.

[JohnnyPatolla]

I have an issue with the fuel consumption during qualy in career mode with Sauber in Australia. The fuel doesn't decrease during the laps. So if I start the run with 5 laps fuel, I finish the qualy lap with the same amount. There are other several bugs in this mode. During free practice Alo set a time 23sec faster than anyone else. Always in free practice 6 drivers were DQ because they crashed each other at the end of the pit lane. You have to resolve a lot of issues

Okay.

I just made a 20min video to explain precisely how the bug occure in FP.

https://www.youtube.com/watch?v=KoBHI-C-TA4

Here a timecode of differents actions

00:00 – 01:00 Creating a new career
02:10 : R&D progress
02:28 : Starting FP1
02:43 : Set 27 kg of fuel
02:55 - 06:23 : 2 Laps without the bug fuel. Using various fuel settings
06:23 : Back to the pit menu
06:35 : Starting fuel consumption practice  (without bug)
06:42 - 10:08 - End of fuel consumption practice (without bug)
10:16 :  Fuel consumption practice results (without bug)
!! 10:28 : RESTART SESSION !!
10:41 : Starting fuel consumption practice (WITH BUG)
12:40 : First lap WITH BUG of fuel consumption practice
14:12 : End of fuel consumption practice (WITH BUG)
14:22 : Fuel consumption practice results (WITH BUG)
15:15 : Starting FP3
15:24 - 17:40 : 1 Lap without the bug fuel. Using various fuel settings
!! 17:48 : RESTART SESSION !!
18:00 - 20:00 : 1 Lap WITH the bug fuel. Using various fuel settings

And here another video of the bug during a RACE (not mine)

https://www.youtube.com/watch?v=7ZNBXAGquWo

As you can see, even in the "lean" mode, he can save fuel.

Hope it help. Let me know if you need something else !

[skylinegtr34]

wow, you make a great job, this explane perfectly, now, codies, make a fix shorty!

[VUnit469]

Maxime your a legend ??

Inregards to development tree, in my experience my issue is with a bog stock McLaren no engine mods.

[Aropretim]

I tested around a bit and what I've found looks like the source of the fuel problem in races.

As Maxime10 shows us, there is no fuel consumption after a session restart in FP (and also not in Q).

If you do a race strategy program without the bug and one with the bug, the game just take the average fuel consumption of both programs.

Example (Bahrain 25% distance):

FP1 (without bug): S-compound - 1.8 kg per lap

FP2 (with bug): SS-compound - 0 kg per lap

Average fuel consumption per lap = (1.8 + 0) / 2 = 0.9 kg

So the game thinks you can finish the 14 lap race with just 12.6 kg fuel and every 0.9 kg fuel you put extra will count as a lap of extra fuel. But even on lean and with lift & coast you will need much more.

If you do the race strategy program three times (one without and two with bug) it will be impossible to finish the race even with maximum fuel load.

Until fixed I recommend to NOT USE Restart session in free practises. Use Back to Main Menu instead. That will prevent you from the no fuel consumption bug. You can of course restart Session (i.e. if you crashed). But then you should go back to Main Menu before you do any programs.

If you're sticking in a unfinishable race... well... maybe it will be fixed for existing savegames. If not, retire the car in the race. That will at least save the engine parts.

[ChristerHiort]

Just did the first practice in the first race. Sounds like I should stop until this bug is fixed ?

[CaptainAust]

While i applaud @Maxime10 for that great job. ... Why the hell should we accept being made to pay for a game that we are if fact bug testing. Lets hope a patch can be implemented as fast as it to maxime to make that vid. 

[VUnit469]

An alternate to quiting to main menu you could use flashback. I’ve used flashback for past 4 races and run into no issues as of yet.

i hate it but until the bugs fixed this is what I’m left with. Don’t want to be spending time with all the load screens going to menu n back in.

Nice test ! I think this evening i will upload another video with the race strategy program and then the race.

[efil4ejpeeZ]

I have the same bug in Bahrain. I think you guys covered most of it, but I figured I upload another video as extra evidence/information.
I didn't know it would come out in potato quality but if you squint you can distinguish the steady decrease of the fuel mix counter, even in lean mix.
I tried quiting to main menu, and then going back into the career, and that didn't really work. I hope an upcoming patch will fix any upcoming save game, else I might indeed retire the race. Shame, because I was having a good weekend, haha.

Here's the video, please ignore both my driving skills and the potato quality:

[Dennis67]

First sorry for my english because i‘m from Germany, i hope you will understand me.
This Fuel glitch happens two time in a row for me.
it happens only when it started to rain during a race in career mode.
the first time it started to rain in a race for me was in France i got fuel +0,78 and then when jeff told me  for a different strategy to go on intermediates in this second my fuel goes from +0,78 to -2.45 that changes in one second. I was angry a little bit but i though ok this happend one time and i saved this -2.45 fuel easily on the wet conditions. But the second time this happens was a lot oft worst.
After the france race the next race in austria this happend again. Same type of race start on dry wheahter them after around 15 laps it started to rain and on an few laps later when the track becomes wet and at the point where jeff told you to change the strategy to go on intermediates in this second my fuel goes from i think +.1,15 to -16,65 !!!!!!!!!!! Within a second i was very angry please codemasters fixed this issue this game is so good but there are tooooo many problems please fixed it.
This glitches happend on my career mode. 100% race!

[skylinegtr34]

ridiculous! it's 4 days of release the game, and like very year it's full of bug, codemasters, you need release patch now not from 2 weeks! every year it's the same story...don't lost time for an event and meeting, you game it's broken....

[ArkAngel]

I play on PC here in USA it is steam version.In career mode playing as Haas.
I set  my fuel load for FP2  at 11 Litres and it never used any fuel. I ran 25 laps and still had 11 Litres afterwards

[IronSpidy26]

I am having a similar but opposite issue as this. The fix for me is to quit to main menu and reload the race entirely. Super inconvenient. 

If I flashback anytime during career, the fuel consumption of my car is 0. So if I make a mistake on lap 1, I have 100kg of fuel in the car, and it doesn't go down. Same in the qualifying/practice sessions. There is no fuel consumption, so the car is heavy and tires degrade like normal. 

It's great to overheat and run in max fuel at all times, but makes the car already that much far slower. Williams 100% race career on 101 ai for reference.

[Nastra100]

Just got the bug in Baku. Put +10 laps of fuel and still ran out in a 50% race when in all my history of Codies F1 games I would never need more than +1

Hey @DriverNumber22 ! I'm back with Round 2 of Maxime10 the bug hunter !

Today a video too explain how to reproduce the Heavy consumption bug fuel during races :

https://www.youtube.com/watch?v=cSKe9euufnI

Timecode :

00:00 Starting FP1
00:26 Load car settings
00:31 First strange thing : 11kg = 11.2 laps. Then i add 1kg and now 12kg = 6.7 laps
00:52  Starting Race strategy practice with soft tyres
01:01 - 08:53 5 laps of race strategy practice without the fuel bug
09:01 Result of the race strategy practice without the fuel bug
09:14 Go to FP3
10:09 Go out to see if the fuel bug occure or not.
10:16 - 10:29 No bug fuel
10:30 RESTART SESSION
10:34 Go out to see if the fuel bug occure or not.
10:39 - 10:56 FUEL BUG (no consumption)
11:11 Starting Race strategy practice with Super Soft tyres
11:19 - 19:05 5 laps of race strategy practice WITH the fuel bug (no consumption)
19:14 Result of the race strategy practice WITH the fuel bug (no consumption)
20:00 Race Strategy
20:02 Adding some extra fuel for the race
21:04 Race start
21:07 (best start ever x)
21:07 - 25:45 I stay in mix 3 until i got +1 lap of extra fuel. Then i go to mix 2
25:49 - 27:27 Mix 2. Heavy consumption bug fuel. When i'm at +0.01 laps, i go to mix 1 to try to save fuel...
27:30 - 28:30 Mix 1. Unable to save fuel. Heavy consumption bug fuel.

Let me know if you need something else

[efil4ejpeeZ]

Ah, wow. A -nan(ind) for the fuel per lap value would really mess up the race calculation yeah  :worried:

[Faya]

Hi all,

I've moved and merged a couple of threads together. Many thanks to everyone that's been posting!

[Gabimad]

At first I thought it was a bug. It happened to me for the first time in Baku. He only let me load 63kg of fuel and with that it was impossible to finish the race (100% long race). I searched the internet and found this thread about the problem and I found the solution.

It is not a BUG it really depends on how the race simulation program is implemented (5 laps). During this program you have to get the time requested without using DRS and without using ERS (I mean ERS in default-Medium) and this gives a real consumption in the race when you have neither DRS or slipstream and with the ERS in medium. Doing this program in this way the consumption for the race is perfect and when you use DRS or ERS in the race the estimated remaining fuel increases and does not decrease as it happens if you do not do this training program correctly.

I hope you find it useful, try it and see how everything is adjusted to perfection.

It is not a BUG.

Greetings.

[efil4ejpeeZ]

I don't think that's it, I never touch ERS or fuel during the programs. Still had the bug.

And for what it's worth, it would still be a BUG if what you described causes the team to bring insufficient fuel to finish a race. :wink:

I agree. Doing the race simulation program works for me and the game calculated the fuel correctly for the next races but as you said even doing the program wrong there is nothing warning you and it should load at least enough fuel to finish the race so the developers must fix it. Regards.

Agree as well. What you show never happens to me and it looks like an important bug that must be fixed.

My problem was different than yours. The game doesn't allow me to load enough fuel for the race and I realized that doing the programs as I said the game calculated the fuel correctly so I wrote it here to help someone with the same issue than mine. I though I couldn't continue with my career because of this and doing this I can continue racing. 

I hope Codemasters release and update soon.
