What are the effects of high mileage on a car?

[DeclanFitz]

High mileage affects the lifespan of components such as the engine, chassis suspension, and transmission. Naturally, increased usage leads to more significant wear and tear. Adhesive wear is related to material plasticity (higher plasticity increases susceptibility), working conditions (temperature, pressure, speed, lubrication), and surface roughness. Below is an introduction to car maintenance: 1. Exterior inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect for body damage, tilting, oil or water leaks. 2. Engine and fluids: Check the fastening of engine components and inspect for oil or coolant leaks at joints. Adjust belt tension and inspect the securing of hoses and wiring. Top up engine oil, coolant, and battery electrolyte as needed. 3. Tires: Check tire wear and clean the trunk. Replace tires when tread approaches the wear indicators. Inspect for bulges, abnormal wear, aging cracks, or damage. 4. Cleaning and lubrication: Clean and lubricate hinges on the hood, doors, and trunk. Antifreeze typically lasts 2 years—replace it during maintenance and thoroughly flush the cooling system. Due to brake fluid's hygroscopic nature, replace it every two years.
