- Engine Protection Level: Look for oils that fight wear and heat to keep your engine safe. Pick ones made for tough conditions to cut breakdown risks.
- Oil Type and Viscosity: Choose synthetic oils for better flow in cold or hot weather. Match the viscosity like 5W-30 to your car’s needs for top performance.
- Drain Interval Extend: Select oils that let you go 10,000 to 20,000 miles before the next oil change. This saves time and money while keeping your engine protected.
- Additional Benefits: Go for oils that boost fuel economy and cut engine noise. Check for ones that clean deposits and stop rust for a longer engine life.
- Brand Reputation and Standards: Trust brands like Valvoline or Mobil that meet API SP standards. Pick American-made oils from companies with over 150 years of experience for steady results.
