This is my first ever UOA on this vehicle. Did have a head gasket replaced a few miles ago. Vehicle running very well. Intend to do a short Quaker State HM 10/30W for a few months of summer and then switching the vehicle over to either PP 5w/30 or Mobil 1 5w/30 which I picked up on rebates thanks to people on this forum. Thanks for any input for this vehicle and UOA.
