Maintenance
|
Service Intervals
|
Oil Change:
|
Every 3,000-5,000 miles or 6 months, whichever comes first. Use synthetic oil for extended intervals if preferred and supported.
|
Air Filter Replacement:
|
Every 15,000-30,000 miles or annually.
|
Spark Plug Replacement:
|
Every 30,000-60,000 miles depending on plug type (copper vs. platinum).
