I had seen some posts about concerns with excess oil consumption on silverados with 2.7. My 2019 has 57,000 miles on it and has from my estimation consistently used one quart or more per 2,000 miles. I brought it to the dealership attention. They did some checking and there was some leakage at valve covers, but they did not offer to do anything. They informed me that GM considered oil use of one quart per 2,000 miles acceptable. Their answer was to do an oil consumption check by coming to the dealership every 500 miles to have the oil level checked. The dealership is 40 miles from me so makes it tough and tried to talk to closer dealership about doing this, but they said I had to go to dealership where I purchased. I feel it’s a runaround and frustrated. I’ve owned new s-10, Colorado, and 2 silverados and this is the only oil consumer. Please email me if you’ve had oil consumption concerns/issues.
