The Mitsubishi 4D30 engine is a diesel engine that has been widely used in various applications, including trucks, buses, and industrial machinery. Known for its durability and reliability, the 4D30 engine has become a popular choice among many vehicle owners. In this article, we will explore the engine configuration, engine oil specifications, and service intervals for the Mitsubishi 4D30 engine.
Engine Configuration
The Mitsubishi 4D30 engine is a four-cylinder, water-cooled, inline diesel engine. It features a cast iron block and cylinder head, providing excellent strength and heat dissipation. The engine has a displacement of 3.3 liters, with a bore and stroke of 95 mm x 105 mm. This configuration allows for a balanced power output and fuel efficiency.
Engine Oil Specs
Choosing the right engine oil is crucial for maintaining the performance and longevity of the Mitsubishi 4D30 engine. Here are the recommended engine oil specifications:
- Viscosity: The engine oil should have a viscosity of SAE 15W-40. This viscosity rating ensures proper lubrication in both cold and hot operating conditions.
- API Rating: The engine oil should meet the API CF-4 or higher rating. This rating indicates that the oil has the necessary additives to protect the engine from wear, deposits, and corrosion.
- Oil Capacity: The oil capacity of the 4D30 engine is approximately 7.5 liters. It is important to check the oil level regularly and top up if necessary.
Service Intervals
Regular maintenance and servicing are essential to keep the Mitsubishi 4D30 engine running smoothly. Here are the recommended service intervals for the engine:
- Oil Change: The engine oil should be changed every 5,000 kilometers or 3 months, whichever comes first. Regular oil changes help remove contaminants and maintain optimal engine performance.
- Oil Filter Replacement: The oil filter should be replaced at every oil change. This ensures that the engine oil remains clean and free from debris.
- Air Filter Replacement: The air filter should be checked and replaced if necessary every 10,000 kilometers or 6 months. A clean air filter allows for proper air flow, improving fuel efficiency and engine performance.
- Fuel Filter Replacement: The fuel filter should be replaced every 20,000 kilometers or 12 months. A clean fuel filter prevents contaminants from entering the engine, ensuring smooth fuel delivery.
- Timing Belt Replacement: The timing belt should be replaced every 100,000 kilometers or 5 years. A worn-out timing belt can cause engine damage, so timely replacement is crucial.
