Buying Guide
A good high mileage oil can change how your car feels. I’ve seen old engines run smoother overnight. The right oil can make driving fun again.
- Viscosity Grade: Choose the right thickness for your engine. Thinner oils flow better in cold weather. Thicker oils protect better in heat.
- Synthetic vs. Blend: Full synthetic oils give the best protection and last longer. Synthetic blends cost less but still offer good performance.
- Mileage Rating: Look for oils made for over 75,000 miles. They have additives to protect older engines.
- Additives: Good oils have seal conditioners to stop leaks. They also have cleaners to fight sludge.
- Temperature Protection: Check the oil’s heat and cold ratings. This ensures smooth starts in winter and strong protection in summer.
- Change Interval: Some oils last 10,000 to 20,000 miles. Longer intervals save time and money.
- Brand Reputation: Pick a trusted brand with proven results. Quality control matters for engine health.
- Fuel Economy: Some oils improve miles per gallon. This helps you save on fuel over time.
- Engine Type Compatibility: Make sure the oil meets your car’s manufacturer standards. This avoids damage and keeps warranties valid.
