Toyota 12T Engine Specs
The Toyota 12T engine is a four-cylinder, gasoline-powered engine that was produced by Toyota Motor Corporation. It was primarily used in Toyota vehicles during the 1970s and 1980s. While this engine may not be as common today, it still holds a special place in the hearts of Toyota enthusiasts. Let’s take a closer look at the specifications of the Toyota 12T engine.
Engine Configuration
The Toyota 12T engine is an inline-four engine with a displacement of 1.6 liters. It features an overhead camshaft (OHC) configuration, which means that the camshaft is located in the cylinder head. This design allows for better control of the engine’s valves, resulting in improved performance and fuel efficiency.
The engine has a bore and stroke of 80 mm x 78 mm, and a compression ratio of 9.0:1. The compression ratio refers to the ratio of the cylinder’s volume when the piston is at the bottom of its stroke (bottom dead center) to the volume when the piston is at the top of its stroke (top dead center). A higher compression ratio generally leads to better engine efficiency.
Engine Oil Specs & Service Intervals
Proper engine oil is crucial for the smooth operation and longevity of any engine, including the Toyota 12T engine. Here are the recommended engine oil specifications and service intervals for the Toyota 12T engine:
- Engine Oil Type: It is recommended to use a high-quality, multi-grade engine oil with a viscosity of 10W-30 or 10W-40. This ensures proper lubrication and protection for the engine components.
- Oil Capacity: The oil capacity of the Toyota 12T engine is approximately 3.5 liters. It is important not to overfill or underfill the engine oil, as it can affect engine performance and potentially cause damage.
- Oil Filter: Regularly replacing the oil filter is essential to maintain the cleanliness of the engine oil. It is recommended to change the oil filter every time you perform an oil change.
- Service Intervals: The recommended service interval for the Toyota 12T engine is every 5,000 kilometers or every 3 months, whichever comes first. Regular oil changes and maintenance help ensure optimal engine performance and longevity.
