In this episode, I answer real viewer questions pulled directly from YouTube — the same questions I hear every day as a GM technician.

We cover 5W-30 oil use in the 3.0 Duramax, early oil changes and engine break-in, blowby expectations, LM2 teardown findings, LZ0 improvements, long-term wear concerns, engine swaps, and what the future looks like for the 3.0 Duramax platform.

No speculation. No warranty talk. Just practical, real-world answers based on what I’m seeing in the shop.
