Maintenance
|
Service Intervals
|
Oil Change:
|
Typically every 5,000-10,000 miles or 6-12 months, depending on operating conditions. Consult manual for specific interval and engine type.
|
Air Filter:
|
Inspect every 10,000 miles, replace as needed or every 20,000-30,000 miles. Severe duty may require more frequent replacement.
|
Fuel Filter:
|
Replace every 15,000-30,000 miles or as per manual recommendation. Crucial for diesel engine health.
|
Fluid Specifications
