Interesting Tom. My Yukon is a 2016 and performs almost exactly the same as yours. We just went to Lancaster and I noticed the mileage dropped to19+ on the way back but was in the low 20s on the way there. Might have something to do with the wind direction but who knows. Like you I always run 87 octane, usually Chevron. Hint buy gas at Vons in Bishop for about 5 cents cheaper than anything in town. Mike

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
