With Real Machine Fluids, you can handle grease, engine oil, antifreeze and hydraulic oil as separate options. You also get fluid levels, refill intervals and supply containers to work with.
Installation
Leave FS25_GreaseAndMotorexOil.zip zipped, then drop it into your FS25 mods folder.
Turn on Real Machine Fluids while loading your save, and keep just one copy enabled.
The original ZIP filename stays in place so existing savegame references keep working.
Do not run the two original FS22 source mods alongside this package.
Features
- In the vehicle shop or workshop, use Yes/No options to switch grease, engine oil, antifreeze and hydraulic oil on independently.
- Fill-unit saving works through the native system.
- Enable them and the Oil, grease, AF and HYD level bars show up beside the speedometer.
- Get within 8 metres of a compatible supply container and use the native refill prompt.
- Make sure the product matches the vehicle tank.
- Oil interval: 1-100 operating hours, default 5.
- Grease consumption: Off through 500%, default 100%.
- Antifreeze and hydraulic oil refill intervals: 1-100 operating hours, default 50.
- Only the server uses up fluids, and host settings are saved with the savegame.
- XML, file references, Lua compilation and mocked behavior regression checks pass.
- You still need to test the full in-game behavior with your game and mod setup.
Specifications
- The engine oil, antifreeze and hydraulic oil options use a small jug, 2.5 US gallon jug and bucket.
