Toyota 3FE Engine Specs
The Toyota 3FE engine is a 4.0-liter, inline-six gasoline engine that was introduced in the late 1980s. It was primarily used in Toyota Land Cruiser models, known for their durability and off-road capabilities. Let’s take a closer look at the specifications of this engine.
Engine Configuration
The Toyota 3FE engine features an inline-six configuration, meaning it has six cylinders arranged in a straight line. This configuration offers several advantages, including smooth operation, good balance, and compact size. The 3FE engine has a cast iron block and cylinder head, providing strength and durability.
- Displacement: The engine has a displacement of 4.0 liters, or 3956 cc.
- Bore and Stroke: The bore and stroke of the 3FE engine are 94 mm and 100 mm, respectively.
- Compression Ratio: The compression ratio is 8.7:1, which is relatively low compared to modern engines. This lower compression ratio helps in reducing the risk of knocking and allows the engine to run on lower octane fuel.
- Valvetrain: The 3FE engine has a single overhead camshaft (SOHC) design with two valves per cylinder. This design simplifies the valvetrain and contributes to the engine’s reliability.
- Fuel System: The engine is equipped with electronic fuel injection (EFI), providing precise fuel delivery and improved fuel efficiency.
Engine Oil Specs & Service Intervals
Proper maintenance of the engine is crucial to ensure its longevity and optimal performance. Here are the recommended engine oil specifications and service intervals for the Toyota 3FE engine:
- Engine Oil Type: The recommended engine oil for the 3FE engine is a high-quality, multi-grade oil with a viscosity of 10W-30 or 10W-40. It is important to use oil that meets the API (American Petroleum Institute) service classification of SJ or higher.
- Oil Capacity: The engine oil capacity, including the oil filter, is approximately 6.5 liters.
- Service Intervals: It is recommended to change the engine oil and oil filter every 5,000 kilometers or 3,000 miles, or every six months, whichever comes first. Regular oil changes help remove contaminants and maintain proper lubrication within the engine.
