Now 2022, I bought a 2018 Silverado in 2019. Used it little due to owning (2) varied year Avalanches, an Equinox and an RV built on a 3500 Express Van chassis.
I have done oil changes on my and other vehicles as a homeowner/hobby guy and have NEVER seen the oil consumption I am experiencing on the 2018 Silverado.
I did not realize the "disclaimer" by GM for vehicles that normal (??) consumption can be 2000 miles/quart? Like others stated....REALLY?
I'm not a fan of synthetic oil and like most am being directed in that path for most oil changes to include on the older vehicles but 0-20W just doesn't seem right no matter the tolerances on modern engines.
Stopping at a local Chevy dealership, I was told of the 2000 miles normal consumption. Looking on line within an hour I see the same thing. It about freaked me out when the DIC indicated I was low on oil with none dripping on the concrete or elsewhere. Wasn't even showing on the dipstick and have 3200 miles since my last oil change in Oct 2021.
Think it might be time to check out Dodge or other!
