I have a 2007 Silverado crew cab that seems to have a misfire while in overdrive going up low grade hills. Not sure if it is fuel or electrical issue. Does anybody have any suggestions???

  Then why even change it? What got you the boot before this?

  So you’re saying when you fill with new oil it reads full. But when you drain it, it reads full but comes out a qt low? I have no words.

  I think this is the closest I'm going to get to reconciling your statements with my experience. Can you confirm you haven't measured the amount of oil drained from your engine to verify what quantity was in the engine at time of drain? For what its worth, the quote above EXACTLY replicates my observations on my 2015, 2016 and 2018, no measurable drop on the stick. EXCEPT that when I measure the oil volume drained from the pan - the drained volume is about a quart less compared to a new fill.

  A little late to this. I am going to order a 2027 as soon as the order banks open. It'll be a 3.0l again. This time in a Yukon.

  I know when I was looking around last year to see if someone handled Amsoil gear oil to buy at the retail level which of course means full price. I found an independent shop that works a lot on GM/Duramax pickups and they did not bring in the 75W-85 as they just stuck to the 75W-90 for the front and rear as a standard practice for the HD trucks which makes sense anyway for the higher hp/torque diesel and pulling heavy loads in four wheel drive. I haven't changed my diff oils yet but still plan on using the 75W-85 for the front diff as I highly doubt I will be beating on the truck and figured for my use type the bit thinner oil would be to my benefit for the winter for that slightly less drag. Very different weather here all winter vs northern Washington near the coast, that's for sure.
