Frequently asked questions
- How often should I change my oil?
- Conventional oil: every 3,000–5,000 miles. Synthetic blend: 5,000–7,500 miles. Full synthetic: 7,500–10,000 miles or more. Always follow your vehicle's owner's manual.
- Does driving style affect oil change frequency?
- Yes. Severe service (short trips, extreme temperatures, towing, dusty conditions) shortens intervals. Check your manual's 'severe duty' schedule if this applies to you.
