How can a person who borrows a car but doesn't want to refuel refuse?

I don't want to borrow my car. I don't want to get it dirty. My car is not for anyone else. My car is also my private property, so I don't want to lend it to anyone. I think in this case, you can tell him that my car doesn't need gas. If you want to use it, you can fill it out yourself and leave me alone. I think if you really don't want to lend your car to others, you can tell him that my car doesn't refuel and I don't need you to refuel me. I think you should tell him that I won't borrow my car, because you are not my friend and I don't want to lend it to you. I think this kind of person is really annoying. If it were me, I would tell him directly that my car doesn't refuel, and you can refuel yourself if you want to use it. If it were me, I would tell him directly that my car doesn't need gas, so you can use it yourself.
