EDIT: Confirmed working on ALL servers!
Tested only on intoxicated, but I’ve seen ape have a car with only 1 low grade. The method he described didn’t work in my testing, he basically said to damage car cockpit until you see break lock and then put 1 low grade and create a car key repair. However my testing showed this didn’t seem to work until an engine part broke, so it appears there is no need to damage anything just remove 1 car part. But thank you Ape either way, this was your finding, would not have considered otherwise.
Rust Car Uses No Low Grade Bug
1. Get a car with 2 engines
2. Put car on car lift
3. Put 1 low grade in fuel storage
3. Create new key
4. Remove 1 engine part form any of the engines
5. Drive car off
6. You can now replace the engine part
Not a major bug, since cars use very little low grade already, but now you can drive a car forever without any low grade.
