How often should you change the oil in a 2002 Chevy Avalanche?
Oil-change intervals by oil type
- Conventional oil: Change every 3,000 miles (4,800 kilometers) or every 3 months, whichever comes first.
- Synthetic blend: Change approximately every 5,000–7,500 miles (8,000–12,000 kilometers) or every 6–12 months, whichever comes first.
- Full synthetic: Change roughly every 7,500–10,000 miles (12,000–16,000 kilometers) or once per year, depending on driving conditions and manufacturer recommendations.
Driving conditions that affect oil-change frequency
- Frequent short trips and city driving with lots of stop-and-go traffic
- Regular towing, heavy payloads, or sustained high engine workload
- Extreme temperatures, whether very hot or very cold
- Dusty, dirty, or harsh environmental conditions
- High mileage or signs of engine wear that affect oil consumption
