Why New Engines Are Dying Before 100,000 Miles

A man walks into a shop with 81,000 miles on the odometer and walks out being told he needs a new engine. He changed the oil when the car told him to. He never raced it. He never skipped a service. It is not him. And it is probably not you either. Modern engines are better machined, better designed and better controlled than anything your father drove — and they are dying earlier. This video explains exactly why, and what the target actually was: most powertrain warranties end at 5 years or 60,000 miles, and everything else follows from that one number. Six of these reasons wear an engine down slowly, and you can fight all six starting this week. ⭐ The seventh gives you almost no warning at all — and it is sitting inside a very common type of small turbocharged engine right now. If you own one, you want to know before it happens, not after. TIMESTAMPS 0:00 An $8,000 bill at 81,000 miles 1:30 Why your father's truck made it to 300,000 3:20 1.

I read the comments — the ones with big numbers on the odometer usually have a story worth hearing. ⚠️ Always use the oil grade specified on your oil cap. Do not switch to a heavier oil in a modern engine based on internet advice — the reasons are explained at 7:40.
