I finally got the hood open on the 200k CGT. After 4000mi w/OT up to 170c(!), it only used 10-12oz. Not bad, I don't wanna hear any more comparisons to conventional oil. I topped with Mobil 1 Truck and SUV, did not want to buy a 'nother whole jug. For engines that can't really use a HDEO 40wt, this oil is a good pick.
