Frequently Asked Questions
How often should I change my oil?
With modern full synthetic oil, most vehicles can go 7,500-10,000 miles between changes. Conventional oil should be changed every 3,000-5,000 miles. Always check your owner's manual for the manufacturer's recommendation, and shorten the interval for severe driving conditions.
What are severe driving conditions?
Severe conditions include frequent short trips (under 10 miles), stop-and-go city driving, dusty or dirty roads, towing, extreme temperatures, and driving at sustained high speeds. Most urban driving qualifies as moderate to severe.
Is synthetic oil worth the extra cost?
Yes, for most drivers. Synthetic oil lasts longer (7,500-10,000+ miles vs 3,000-5,000), provides better engine protection, performs better in extreme temperatures, and may actually save money over time due to fewer changes needed.
