Sounds like you have the kind of chap that believes in traditional gender roles. That might be a stretch as you only gave one example and maybe he just thought you'd had no effin' clue what you were doing and he'd end up driving your car one day and you'd blow a gasket because you did something wrong.

By the way, I have no idea if the gasket has anything to do with an oil change. My point there is this: if you and I were dating, you could change your oil and mine as ofte as you want tootz.

If it means that much to him, I don't see anything wrong with letting him do things for you that you can do for yourself. In fact, its the basis of marriage; two people who could otherwise do plenty of things themselves allowing somebody else to assume certain roles and responsibilties for the greater good of both parties. I mean you let him attempt to get your rocks off in the sack right? You could totally do that yourself if you want to (and hopefully don't need to).

Unless its that big a deal for you to do it yourself then I don't see the harm. Maybe it makes him feel like "the man" to do these things (once again, traditional roles) or he feels like you shouldn't have to because he's around...me no know. But unless it puts you out to let him do it, I don't see the harm as long as he doesn't expect you to revert to those roles to, i.e. he's out changing the oil and expects you to prepare a four-course meal and do the laundry because that's a woman's work.
