You have something else very wrong with your engine. The amount of oil your engine is consuming has nothing to do with dexos/dexos2/dexosR. The LT4 has been around since 2014...way before dexos2 was a thing.They put in the wrong oil inside your car
I just went threw the whole summer and the dealership been putin mobile 1 0w40 without the dexos 2 in it
All factory cadillac V are filled with Mobile 1 super car 0w 40 with dextos 2 in it
I bet you your manufacturer oil change lasted the right amount and ever since the 1st oil change been burning like a mother
Wasted my whole summer burning 3L of oil every 2000km thinking something wrong in engine
Make sure your dealership puts the right oil with dexos 2 in it all LT4 will burn others if not
