We Tested 5.3, 6.0 & 6.2 After 200,000 Miles — A Clear Winner
📘 THE 500,000-MILE GMC BLUEPRINT The complete maintenance system for making your gmc last past 500,000 miles. Protect against the $7,000 AFM lifter failure, service your transmission the right way, and decide repair-or-replace with cold math. No mechanic required. 👉 https://everythinggmc.gumroad.com/l/o... ━━━━━━━━━━━━━━━━━━━━━━━━━━━ I'm Dale, twenty-eight years on the bench, and I've had gmc's 5.3, 6.0, and 6.2 apart at 200,000 miles more times than I can count. One of them is barely broken in at that mileage. Another is often already dying. This is what the teardown actually shows. The catch nobody tells you: at 200,000 miles it's not the displacement on the badge that decides what survives — it's the generation underneath it. Two engines wearing the same 5.3 badge can be opposite stories. The early LM7 5.3 and the LQ4/LQ9 6.0 are Gen III iron with no AFM — survivors. The AFM 5.3s and the Gen V direct-injection 6.2s carry the failure modes that end engines early. I'll give you the honest verdict on all three — the clear longevity winner, why the 6.2 still wins on power, why the 5.3 wins on value — plus the one VIN trick that tells you exactly which engine you're holding. Which one's under your hood? Drop it in the comments.
