Car Maintenance Guide

Oil and filter changes are the single most important maintenance item for engine longevity. Modern full-synthetic oils and extended-life filters mean most newer vehicles go 5,000–10,000 miles between changes (check your specific owner's manual — it varies by manufacturer and driving conditions). Using a quality synthetic oil appropriate for your climate and following the manufacturer's interval keeps internal engine surfaces protected and contaminants managed. Tire rotation every 5,000–7,500 miles promotes even wear and extends tire life. Properly inflated and rotated tires also improve fuel economy and handling. Check tire pressure monthly — pressure drops about 1 PSI per 10°F temperature drop, so seasonal pressure changes are significant. Replace tires before the tread depth reaches 2/32" (use the penny test or a tread depth gauge).

Brake pads typically last 30,000–70,000 miles depending on driving style and brake pad material (organic pads wear faster; semi-metallic and ceramic pads last longer). Have brake thickness checked annually; replace pads before they wear to the metal wear indicator (you'll hear squealing when they're near their limit). Ignoring worn pads leads to rotor damage — a $80 pad replacement becomes a $300–$600 brake job. Fluid maintenance is often overlooked but critical: engine coolant needs replacement every 5 years or 100,000 miles in most vehicles. Transmission fluid, if not a 'lifetime fill' type, needs replacement every 30,000–60,000 miles. Brake fluid absorbs moisture over time and should be flushed every 2–3 years. Power steering fluid and differential/transfer case fluids have service intervals in your owner's manual.
