Depending on the type, the International DT466 diesel engine can hold 28 or 30 litres of engine oil. Oil changes and filter replacements are advised every 15,000 miles of operation for 30-liter cars and every 13,000 miles for 28-liter models.
Regardless of the distance covered since the last oil change service, the engine’s manufacturer suggests changing the oil and filter after 500 hours of operation for 28-liter engines and 550 hours for 30-liter DT466 models.
The six-cylinder, inline “wet-sleeve” architecture of the International DT466 diesel engine is unusual for mid-range diesel engines like the DT466 but is standard for large industrial diesels.
The DT466 engine’s cylinder walls remain in direct touch with the engine coolant thanks to the wet-sleeve design, which increases cooling effectiveness but comes with some additional maintenance needs.
Although the cylinder walls of the engine are harder and more uniform than the softer cylinder walls of conventionally cooled engines, the wet-sleeve design also increases overall engine durability.
Since the 1970s, many different iterations of the DT466 have been built. Because different variations are tailored for either normal or high-torque applications, engine outputs have varied significantly even among engines produced in the same model year.
The DT466’s standard-torque variants have a maximum torque of 620 foot pounds, while its high-torque engines have a maximum torque of 800 foot pounds.
