How often should I change my oil?

It depends on oil type and driving conditions. Conventional oil needs changing every 3,000-5,000 miles, synthetic blend every 5,000-7,500 miles, and full synthetic every 7,500-10,000 miles. Check your owner's manual for manufacturer recommendations.

Is synthetic oil worth the extra cost?

Yes, for most drivers. Synthetic oil lasts 2-3 times longer than conventional oil, provides better engine protection, performs better in extreme temperatures, and can improve fuel economy. The higher upfront cost is offset by fewer oil changes per year.

Can I go longer between oil changes with synthetic oil?

Most modern vehicles with synthetic oil can safely go 7,500-10,000 miles between changes. However, severe driving conditions (frequent short trips, extreme temperatures, towing) may require more frequent changes. Always follow your manufacturer's recommendations.
