About Maintenance

Maintenance is the least glamorous part of car ownership and the most rewarding. A few hundred dollars a year in oil, filters, tires and fluids is what separates a car that runs for decades from one that dies an early, expensive death. Yet the advice drivers hear is often contradictory: every 3,000 miles or every 10,000, premium fuel or regular, dealer or independent shop. This page sorts through the routine care cars need and the debates that surround it.

The rules have changed considerably over the years. Older cars needed frequent oil changes, regular tune-ups and seasonal attention, and the 3,000-mile oil change became gospel at quick-lube shops. Modern synthetic oils and tighter engines stretched those intervals dramatically, and many cars now use oil-life monitors that calculate service timing from how the car is driven. Tires lasted longer, spark plugs went 100,000 miles, and some fluids were marketed as lifetime fills, a claim many mechanics view with suspicion.

Today's maintenance questions reflect today's cars. Turbocharged and direct-injection engines raise concerns about carbon buildup and oil dilution, start-stop systems demand stronger batteries, and heavier SUVs and electric cars chew through tires faster. EVs skip the oil change but still need brake fluid, cabin filters, coolant for their batteries and careful tire care, and owners increasingly track battery health as closely as earlier generations watched oil pressure. Severe-service schedules, extreme climates and short trips all change the calculus.

Expect seasonal checklists, service-interval explainers, battery and tire guides, studies on maintenance costs by brand and warnings about common mistakes. Owner's manuals remain the final word for any specific car, but the news here helps explain what the manual leaves out. Following the right schedule for the way a car is actually used, rather than an optimistic marketing figure or an upsell at the service counter, remains the cheapest insurance against the large repair bills that end so many cars' lives.

Maintenance

Oil changes, tire rotations, brake pads, batteries and service schedules: the routine care that decides whether a car reaches 200,000 miles.
