How Much Oil Consumption Is Okay In A Car?

So im looking to buy my first car and i have no idea how much oil a car should be using up in a given amount of time. I found 350z for sale with low mileage but it is the 2006 model. That year has some cars with high oil consumption and some that are normal. This specific car burns 1/2 a quart of oil every 1000 miles if driven consistently over 4000RPM according to the dealer. Is this too much? it sounds like too much to me but ive never owned my own car before so ive never maintained one either.

    kevin, the old jags used as much as 2 quarts to a tank of fuel, it all depends on the vehicle, the machined tolerances, and how you drive it.

    If the dealer says 1/2 a qt every 1000 miles over 4k rpms, its probably more like 3 qts no matter what the rpms. Remember, all car dealers are liars.
    Also, who drives over 4k rpms all the time?
    I wouldnt buy it, sounds like the dealer is hiding a problem. Plus 350z’s arent very reliable, and repairs are really expensive.
