If it's a steam version then you should probably prepare for the fact that you wont be able to play it unless

1) You download a crack for exe to remove DRM

2) You ask Codemasters for a working securom key (a key that you have to type when launching the game, it's not the same as Steam key)

How to install FUEL (plays and saves).
To get it to work in a LEGIT way (just wrote this to save people some hassle)

Installation Guide (as of 15 July 2016) To get it to work follow these steps:

SecureRom issue:
1) the steam serial activates on steam but a SecureRom thing pops up asking you to enter a serial (the previous steam serial doesn't work)
2) you need to email Codemasters for a key for this SecureRom, they answer and give you a SecureRom key within the same day (if it's a weekday)

Games For Windows Live issue:
3) game still doesn't run from steam but it finally will if you install Games For Windows Live client (note: login from external GFWL client not necessary)
4) to be able to save in the game you need to login to windows live within the game with your GFWL/Xbox Live email and password. Then copy a new key (yes a 3rd key) by right clicking fuel in your steam library, copy key, and then paste it, and enter the key into gaming for windows live within Fuel. Then GFWL updates, asks you to sign in AGAIN, then a GFWL within the game says ''downloading profile, this process may take a few minutes-don't close the game'' it takes 3-4min ....then a loading bar increases and the game runs and saves fine.

How many liters?

It is pretty bad though.
