Firstly, coming from somebody that has personal experience with working on vehicles this kind of tutorial is a cakewalk. But one problem being is it’s not practical.. now let me explain
1. It’s unrealistic
The game does procedures out of order and forgets to do steps like ‘filling the oil’ and than starting the engine without it like it will magically work..
2. Thats leads to it being potentially dangerous
If someone that was completely new game to this game, did these steps, and tried it themselves with the overconfidence that this taught this something. Than that would be a lie, and infact how you do these steps could damage your engine. Like for example, not draining the old oil, than adding new oil, or just not adding the oil at all just like what I just did (ingame) and somehow not having it leak out which never happens, it will since its connected. By overfilling or underfiling you risk engine damage.
Just don’t bother with a game, especially this one. You want to learn about a car? Find a hiring mechanic shop for part time to help teach you, or a relative and friend.
