the use of these
https://www.amazon.com/Range-Technol...sabling+device does work so the engine stays in V8 mode which then eliminates the engine damage. I would try it and see if the oil use drops. also you must use dexos GM approved engine oil if not then this does occur at a much lower mileage. had a guy with a 2013 65K miles with this problem use some synthetic mix oil rather than dexos spec. if you did not use the dexos oil spec I would buy that DOD tool and also put 5 OZ of MMO into the engine oil and change the oil after a few hundred miles to remove all the sludge which it is reported causes the oil to burn off because of plugged up drain back issues . MMO =marvel mystery oil........post back if it works out .. you have lots of fellow GM truck owners with these issues GM should be sued .
