Burning oil is so hit and miss.
My buddy's 2011 silverado burns zero oil and its over 25K miles, then theres this other person we know and his truck burns 1 quart per 3k miles. Which by GM standards is 100% normal. So I wouldnt be turned away by the minor fact that it may burn 1ish quarts per 3,000 miles, figure its only 3-5 bucks worth of oil that you are using for that given time.
