However, a good general guideline is every 3,000 to 5,000 miles.
* 3,000 miles: This is a more conservative approach, suitable for those who frequently tow heavy loads, drive in extreme temperatures, or experience stop-and-go city driving. It's better to change it more often than less often.
* 5,000 miles: This is a more common interval, suitable for average driving conditions.
Crucially, always consult your owner's manual. The manufacturer's recommendations are the most accurate for your specific vehicle and should supersede any general advice. The manual will likely specify intervals based on mileage or time, whichever comes first. Modern synthetic oils may allow for longer intervals, but again, check your manual.
