Mitsubishi 4M50 Engine Specs
The Mitsubishi 4M50 engine is a powerful and reliable diesel engine that is commonly used in commercial trucks and buses. This engine is known for its durability, efficiency, and impressive performance. In this article, we will explore the specifications of the Mitsubishi 4M50 engine, its configuration, engine oil specifications, and service intervals.
Engine Configuration
The Mitsubishi 4M50 engine is an inline four-cylinder diesel engine with a displacement of 4.9 liters. It features a cast iron block and cylinder head, which enhances its strength and durability. The engine is equipped with a common rail fuel injection system, which ensures precise fuel delivery and efficient combustion.
The 4M50 engine is also equipped with an intercooled turbocharger, which helps to improve its power output and overall performance. This turbocharger compresses the incoming air, allowing for more oxygen to enter the combustion chamber, resulting in increased power and torque.
Engine Oil Specs & Service Intervals
Proper engine oil specifications and regular maintenance are crucial for the longevity and optimal performance of the Mitsubishi 4M50 engine. Here are the recommended engine oil specifications and service intervals:
- Engine Oil Type: It is recommended to use high-quality diesel engine oil that meets the specifications of API CJ-4 or better. This ensures proper lubrication and protection for the engine components.
- Oil Viscosity: The recommended oil viscosity for the 4M50 engine is 10W-30 or 15W-40, depending on the operating conditions and climate. Consult the owner’s manual or contact a Mitsubishi authorized service center for specific recommendations.
- Oil Change Interval: The oil change interval for the Mitsubishi 4M50 engine is typically every 7,500 miles or 6 months, whichever comes first. However, it is important to note that the oil change interval may vary depending on the operating conditions and the type of oil used. Regular oil analysis can help determine the optimal oil change interval for your specific application.
- Oil Filter Replacement: It is recommended to replace the oil filter during each oil change to ensure proper filtration and prevent contaminants from circulating in the engine.
Regular maintenance, including oil changes and filter replacements, should be performed by qualified technicians or at a Mitsubishi authorized service center to ensure the best performance and longevity of the Mitsubishi 4M50 engine.
