That's good mileage for an 03 Park Avenue. You must be using premium gas.
Nope, 87 octane. I just drive it like a typical Park Ave owner. I tend to drive a little fast on the highway, even though it takes me forever to get up to speed.
Seems like everyone has their own opinion on what has the largest impact...
