Hey EFLine. I'm new on here and just stumbled on your post about "oil consumption." I have a 2014 Silverado LTZ and just had it serviced yesterday. I have about 60K miles on it and it's started using, (not burning or leaking) about 1.5 to 2.0 quarts between oil changes. I use synthetic oil but still get oil changed way before the 7500 mile recommendation when using synthetic. The dealer told me that oil usage like that was normal and provided me with some printed info from GM stating that. They recommend that I do a oil usage test between oil changes and gave me some forms to use and fill out documenting the oil usage. I told the that the truck does that on it's own by notifying me that it's low on oil. Then I check the oil and it's sure nuff it's low, then I add a quart or so depending on what is needed. What more test do they require than that? I'm 62 and have my share of vehicles. Back in the day when a vehicle began using oil, we never thought it was normal. I had a 1968 Z/28 Camaro, a 1967 SS Impala, a couple of pickups during the 80's and even sold Chevys for a good while in the late 70's and early 80's. I don't remember any of those using between 1.5 and 2 quarts of oil between oil changes. My how times have changed! I'm looking at a 2018 LTZ now and you can bet I will have this conversation with someone at the dealership before I stroke a check! (BTW my wife works for the dealer as their office manager and she asks me not to go back in service and make a fool of myself )
