    My first pickup - 1985 Nissan pickup (manual) averaged 25mpg.

    Curious how fuel efficiency holds up over time. Does a 10, 20, 30 year old car averaging 10K miles a year still basically get the same efficiency as a new one?

      It can. It would require the engine to be a good production version (which it may be if it has the miles and hasn’t already had problems), good maintenance through its life, and a bit of luck. Would most cars, probably not. There’s too many variables to cause original efficiency to decline, one big one being typical abuse and neglect.
