What really happens when your car hits 100,000 miles? Most mechanics won’t tell you — but it’s the turning point that determines whether your car makes it to 200k or ends up in the junkyard. In this video, we reveal the insider secrets that every experienced mechanic follows once a vehicle crosses the 100,000-mile mark… but they rarely share with car owners. Why? Because knowing these tips could save you thousands in repairs and extend your car’s life by years. We break down the essential car maintenance every high-mileage vehicle needs, from hidden timing belt inspections to often-overlooked fluid changes and engine diagnostics. You’ll learn why transmission service is critical, which components wear out faster after 100k, and the one fluid change most shops conveniently skip — even though it protects your engine more than oil! If you want to avoid surprise breakdowns, massive repair bills, or worse — buying a new car prematurely — you need to know these professional habits. This is your ultimate 100,000-mile car survival guide. Whether you're a DIYer or just want to understand what your mechanic should be doing, this video gives you real value based on years of shop experience. 👉 Watch to the end for a bonus pro tip that could save your engine! #carrepairtips, #highmileagemaintenance, #savemoneyoncars
