Rolled 355,000 miles last Thursday on a weekend trip from Arlington to Lake Ouachita. The X5 delivered 23.7 mpg over the 700 mile weekend and only used (seeped) a half quart of oil. But that's what keeps the rust off the chassis, right. Just wish I could get the idle to be smooth again when it's below 75 degrees outside. A new MAF didn't help.
