Talked to an old CAT tech and now I think fleet maintenance is backwards

Had coffee with a retired CAT master tech last week in Odessa and he said swapping parts early is how shops stay busy, not how engines stay alive. He showed me oil samples from 3 trucks that got new injectors at 200k and all 3 lost compression by 350k, while ones he ran to 500k on stock parts never opened up. Anyone else see shops pushing preventive swaps that actually do more harm than good?

My uncle ran a small dump truck fleet out in Midland and he had the same gripe about tire shops. They'd sell him a full set every 18 months saying it was "safety" but his old rigs ran fine on tires way past that. Shops got bills to pay so they sell you stuff you don't need yet.
