For all of those that use a Silverado to haul the boat around. If you have the fuel management system and are having an issue with excessive oil consumtion, get it into the dealership and have them document the problem! Mine is a 07 with 125,0. There is a problem with the rings and pistons, also the lifters, oil pump, and cam shaft. If it's not documented and you are past warranty, it's on you. Don't let the dealer or Chevy try to make you pay for half the repairs and they WILL try! This is a manufactures defect! It really shows it's face when you're hauling weight, mine was up to two quarts every 1000 miles. She goes in for a rebuild on Dec 26.
