Hi,

I need to know if I have to get a specific replacement oil cap for my '06 Aveo. I took it to the dealer to get the oil changed today and they didn't put the cap back on. Naturally, they're closed until Monday and I can't get a hold of anyone there, but I need to use my car. Not auto parts store has said they have a specific replacement part. Can I just use a universal cap or something?

Thanks!
