The GM L3B Turbomax 2.7L motor has been known to consume oil. I recommend checking the oil level frequently and changing it out sooner and more frequently than the OLM says. My experience with this motor is it burns between 1 and 1.5 quarts of oil over the course of an oil change of 5,000 miles. I top it off every 1000 miles or so to keep the level normal. I have checked it once and the oil level didn't even register on the dipstick! It is not leaking, anywhere, I have done a thorough inspection of the engine, and there are no drip marks anywhere that I can see. I recently switched to a high mileage oil to see if that helps with the oil consumption.
Trucks that can be equipped with this engine:
2019+ Chevy Silverado
2019+ GMC Sierra
2023+ Chevy Colorado
2023+ GMC Canyon
The motor RPO code is mostly L3B, robert smigel but also seen as L2R in some work truck models on the 2023+ Colorado/Canyon
