Notes
Oil Filter Replacement: Always include the oil filter volume when calculating total oil capacity. This is already considered in the figures above.
Check the Dipstick: After filling oil, always verify using the dipstick to ensure proper levels, especially if the engine has been rebuilt or modified.
Operating Conditions: Severe duty operations (e.g., towing, stop-and-go traffic, dusty environments) may require more frequent oil changes.
Oil Grade: Most Sterling models use 15W-40 conventional or synthetic blend diesel engine oil.

Recommended Oil Change Intervals
Oil change intervals depend heavily on the type of engine, oil quality, and working conditions. Below are typical ranges:
- Light-Duty Sterling (e.g., Bullet models): Every 7,500–10,000 miles
- Medium-Duty (Acterra): Every 10,000–15,000 miles or every 250–300 engine hours
- Heavy-Duty (LT9500, A9500): Every 15,000–25,000 miles, depending on duty cycle

Tips for Maintaining Your Sterling Engine
- Use High-Quality Oil: Fully synthetic or premium diesel engine oils offer better protection, especially in high-load and high-heat environments.
- Monitor Oil Pressure: Regularly check the oil pressure gauge; sudden drops may indicate leaks, oil pump failure, or blockages.
- Inspect for Leaks: Oil leaks around the valve cover, oil pan, or gaskets should be fixed immediately to prevent engine damage.
- Sample Your Oil: Fleet operators benefit from oil analysis programs that detect contamination, wear metals, and oil degradation.
- Change Oil Filters: Always replace oil filters during every oil change to ensure contaminants are removed effectively.
