Toyota 3S Engine Specs
The Toyota 3S engine is a series of inline-four internal combustion engines produced by Toyota Motor Corporation. These engines were primarily used in various Toyota models from the late 1980s to the early 2000s. The 3S engine series includes the 3S-FE, 3S-GE, and 3S-GTE variants, each with its own unique specifications and performance characteristics.
Engine Configuration
The Toyota 3S engine series features an inline-four configuration, meaning it has four cylinders arranged in a straight line. This configuration offers a good balance between power, efficiency, and compactness. The engine block is made of cast iron, providing durability and strength.
The 3S-FE and 3S-GE variants have a displacement of 2.0 liters, while the 3S-GTE variant has a slightly larger displacement of 2.0 to 2.2 liters, depending on the specific model. These engines utilize dual overhead camshafts (DOHC) and multi-valve technology, typically with four valves per cylinder, to optimize airflow and enhance performance.
Engine Oil Specs & Service Intervals
Proper engine oil is crucial for maintaining the performance and longevity of the Toyota 3S engine. Here are the recommended engine oil specifications and service intervals:
- 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. Always refer to the vehicle’s owner’s manual for the exact oil type and viscosity recommended by Toyota.
- Oil Capacity: The oil capacity of the 3S engine varies depending on the specific model and variant. On average, it ranges from approximately 3.7 to 4.5 liters.
- Service Intervals: Toyota recommends changing the engine oil and oil filter every 5,000 to 7,500 miles (8,000 to 12,000 kilometers) or every 6 months, whichever comes first. However, it is important to note that service intervals may vary based on driving conditions and the specific recommendations provided in the owner’s manual.
Regular oil changes are essential to keep the engine properly lubricated, prevent excessive wear, and maintain optimal performance. It is also important to check the oil level regularly and top it up if necessary, using the recommended oil type and viscosity.
