Mitsubishi 4G69 Engine: Specs, Configuration, and Maintenance

Mitsubishi 4G69 Engine Specs

The Mitsubishi 4G69 engine is a four-cylinder, 2.4-liter gasoline engine that was introduced in 2004. It is part of Mitsubishi’s 4G6 series of engines, which have been widely used in various Mitsubishi models. The 4G69 engine is known for its reliability, performance, and fuel efficiency. Let’s take a closer look at its specifications.

Engine Configuration

The 4G69 engine features a DOHC (Double Overhead Camshaft) configuration with four valves per cylinder. This design allows for better airflow and improved combustion efficiency, resulting in increased power output. The engine also incorporates Mitsubishi’s MIVEC (Mitsubishi Innovative Valve timing Electronic Control) system, which optimizes valve timing for enhanced performance and fuel economy.

The bore and stroke of the 4G69 engine measure 87.5 mm and 100 mm, respectively. It has a compression ratio of 9.5:1, which contributes to its efficient combustion process. The engine is equipped with a multi-point fuel injection system, ensuring precise fuel delivery to each cylinder for optimal performance.

Engine Oil Specs & Service Intervals

Proper engine oil selection and regular maintenance are crucial for the longevity and performance of the 4G69 engine. Here are the recommended engine oil specifications and service intervals for this engine:

• Engine Oil Type: It is recommended to use a high-quality synthetic or semi-synthetic engine oil with a viscosity grade of 5W-30 or 10W-30. These viscosity grades provide excellent lubrication and protection across a wide range of operating temperatures.
• Oil Capacity: The 4G69 engine has an oil capacity of approximately 4.2 liters (including the oil filter).
• Oil Change Interval: Mitsubishi recommends changing the engine oil and oil filter every 5,000 miles or 6 months, whichever comes first. Regular oil changes help remove contaminants and maintain optimal engine performance.

It is important to note that driving conditions, such as extreme temperatures or heavy loads, may require more frequent oil changes. Always refer to the owner’s manual for specific recommendations based on your driving habits and conditions.
