- Most trips are less than 5-10 miles. This is particularly important when outside temperatures are below freezing.
- Most trips include extensive idling (such as frequent driving in stop and go traffic).
- Most trips are through dusty areas.
- You frequently tow a trailer or use a carrier on top of the vehicle.
- If the vehicle is used for delivery service, police, taxi, or other commercial application.
Otherwise service the manual transmission fluid every 30,000 miles.
