Maintenance & Tires | Vehicle

About Vehicle Maintenance

Regular maintenance is cheaper than repair, and most of the big-ticket failures (engine, transmission, suspension) can be delayed or avoided by staying on schedule with fluids, tires, and belts. This section covers oil change intervals, tire rotation and replacement, brake pad life, fluid checks, and the printable logs that track all of it. Enter your vehicle details and mileage, and the tools show when each service is due based on manufacturer recommendations and real-world driving conditions.

How Often Should You Change Your Oil Modern oil-change intervals, the truth about the 3,000-mile rule, how manufacturers set synthetic and conventional intervals, severe-service rules, and how oil-life monitors actually work.

How to Check Tire Tread Depth How to check tire tread depth: the penny test, quarter test, and tread-depth gauge, legal vs safe minimums for wet and winter driving, and what uneven wear tells you about your suspension and alignment.

Frequently asked questions

How long do tires actually last?

40,000 to 70,000 miles for most passenger tires, depending on brand, driving style, climate, and rotation discipline. Our tire wear calculator estimates remaining life based on tread depth (measured with a tread gauge or the quarter test) and your typical mileage.

When should I replace tires rather than rotate them?

At 4/32 inch tread depth for wet climates where hydroplaning risk rises; 2/32 inch is the legal minimum in most states. Also replace if there's uneven wear, sidewall damage, or the tires are more than 6 years old regardless of tread depth.

Do I need to use the oil grade specified in the manual?

Yes. Using the wrong viscosity (for example 5W-30 instead of 0W-20) can reduce fuel economy, cause sludge buildup, and void warranty in newer vehicles. Synthetic versus conventional is a separate question; synthetic is always fine if the manual allows conventional.

How do I know when brakes need replacing?

Most pads start at 10-12mm when new and should be replaced at about 3mm. Warning signs before that point: squealing (wear indicator tab hitting rotor), longer stopping distance, or a pulsing pedal (warped rotors). Get brakes inspected at every oil change.

How often should I rotate my tires?

Every 5,000 to 7,500 miles, or at each oil change, whichever comes first. Skipping rotation causes uneven wear on front tires (from steering and drivetrain on FWD) that shortens the set's life by 30% or more.
