I recently bought a 23 Colorado ZR2 which has the 2.7L Turbo engine and did a bit of research on the engine before purchase. So far I'm impressed with the engine.
I was watching a YT video of an interview with one of the GM engineers that developed the engine. One of the comments he made was that the engine was designed to run on 0w-20 oil but they recommend 5w-30 for increased protection and longevity. I thought that was interesting and it goes along with my general thoughts on oil viscosity.
