Farming Simulator 18

This will come naturally as you progress through the game and can be tracked in your statistics. You don't personally have to use 1,000 litres of diesel, because hiring workers to do your sowing, harvesting, cultivating and any other jobs will help earn you this trophy. You should earn this a few hours into your playthrough and will have used around 10,000 litres by the time you have the Platinum.
