 I have an 02 Maxima automatic with 70,000 miles bought almost 3 years ago with 45,000 miles.Mine burns oil, one to two quarts between changes every 4,000 miles.I also bought an 03 Altima V6 and it does the same thing, leading me to believe that this is a very common problem.However, the cars are cheap to buy used and a quart or two of oil between changes is less than $10, so why bother putting in new rings? I ran regular gas for the first 2 1/2 years--a mistake.The drivetrain, including the transmission, works better with premium.The solid rear axle in this car makes for inferior handling compared to the Altima, but the latter lacks the "elan" of the older Maxima in my view
