I can't count on my own family for favors either.", "Well, he's usually dependable. And it is a favor to begin with, so I can't get too mad. It's just I asked for it as the only thing I'd like for my birthday, and I was kind of hoping for it to be done."]
Maybe you should tell him how urgent the oil change is. Maybe he will understand.
