Car Maintenance Tips

Overview

The video presents 17 essential maintenance habits aimed at extending a vehicle’s lifespan to over 500,000 miles while avoiding costly repairs. The recommendations challenge manufacturer guidelines and emphasize proactive, real-world car care.

Oil and Fluid Maintenance

  • Change engine oil every 3,000–5,000 miles, not the factory-extended interval, for maximum engine longevity.
  • Always use synthetic oil for modern vehicles and conventional oil for older models, consulting the manual or mechanic for specifics.
  • Replace the oil filter with OEM quality at each oil change; avoid cheap filters.
  • Change transmission fluid every 60,000 miles (90,000 for hybrids); drain and fill instead of flushing if never changed before.
  • Use only manufacturer-recommended transmission and coolant fluids without mixing types or colors.
  • Flush coolant every 3–5 years to prevent corrosion and head gasket failure.
  • Flush brake fluid every 2–3 years or when moisture exceeds 3% to maintain safe braking.

Critical Component Replacements

  • Replace timing belts by 60,000–80,000 miles and inspect for wear; change tensioner, idler pulley, and water pump simultaneously.
  • Install high-quality, vehicle-appropriate spark plugs every 60,000–70,000 miles; avoid bargain or incorrect plugs.
  • Replace fuel filters every 30,000–60,000 miles, sooner if operating in dusty regions or with poor fuel quality.
  • Change differential and transfer case fluids as per manual, more often if towing or using AWD.

Preventing Wear and Detecting Problems Early

  • Replace the PCV valve every 30,000–50,000 miles or at signs of oil loss, smoke, or rough idle.
  • Clean the mass air flow sensor every 12,000–15,000 miles to maintain engine performance and fuel economy.
  • Align tires every 6,000–10,000 miles or at every tire rotation to prevent premature tire and suspension wear.

Daily Driving and Environmental Habits

  • Avoid revving the engine when cold; let it idle for 30 seconds, then drive gently until warmed up.
  • Limit engine idling to no more than a minute; excessive idling causes internal engine wear and carbon buildup.
  • Wash the vehicle’s undercarriage monthly in winter or after exposure to salt, sand, or mud to prevent corrosion.
  • Clean battery terminals regularly to prevent starting and electrical issues.

Monitoring and Tracking

  • Listen and investigate any unusual car sounds promptly to avoid escalating repair costs.
  • Keep a detailed maintenance log (paper or app) to track all services, spot patterns, and aid resale or warranty claims.
