How often to rotate tires
Rotate tires every 5,000-7,500 miles. Skip it and the fronts wear 30% faster than the rears, shortening a $200 tire set’s life by 10,000 miles or more.

When to replace brake pads
Brake pads need replacing at 3mm, not when they grind. Wait past that and you’re also buying rotors, which turns a $150 pad job into $400 per axle.
How often to change transmission fluid
Most automatics need fresh fluid every 30,000-60,000 miles, not 100k. Old fluid runs hot and shifts rough long before the transmission actually fails.
How to check engine oil
Checking oil takes 90 seconds on a cold engine and tells you more about engine condition than any warning light. Here’s what the dipstick actually shows.
How often to change brake fluid
Brake fluid absorbs moisture every year and boils at lower temps over time. Most cars need a flush every 2 years, not just when the pedal feels wrong.
