That's an interesting mod you have developed for FS25! Having a small farm diesel production facility that can easily convert rapeseed and sunflowers into diesel for your vehicles and other production needs is quite innovative. The compact size of the facility and the large storage capacities for both the raw materials and the produced diesel make it a practical addition to any farm.
The purchase price of €25,000 and daily maintenance costs of €200 seem reasonable considering the benefits the facility provides. With a storage capacity of 70,000 liters for rapeseed and sunflowers and 80,000 liters for diesel, you can efficiently produce and store enough diesel for your farm operations.
It's great to know that you have thoroughly tested the mod with TestRunner 0.9.17, ensuring that it is error-free and ready for use. Players will surely appreciate your attention to detail and the quality of the mod.
Overall, your small farm diesel production facility seems like a valuable addition to the game, offering a convenient way for players to produce their own fuel on the farm. I'm sure many players will enjoy using this mod in their gameplay. Keep up the good work, and I hope you continue to create more innovative mods for the community to enjoy!
