We're thinking that when DS starts driving, we'll pay for the petrol in his car to help keep him mobile. But rather than hand over cash, I was wondering if we'd be able to get something like a credit card and make him an extra card holder on it, then pay it off (so long as its just petrol going onto it!). But he'd only be 17, assuming he passes his test of course.
Does anyone know if that's ok on an ordinary credit card, or if there's anything else we could get instead?
TIA
