Chevy L98 Engine Specs
Engine Configuration
The Chevy L98 engine is a V8 engine that was produced by General Motors from 1985 to 1991. It belongs to the third generation of Chevrolet small-block engines and is known for its performance and reliability. Here are the key specifications of the Chevy L98 engine:
– Displacement: The L98 engine has a displacement of 5.7 liters or 350 cubic inches. This means that each cylinder has a displacement of approximately 0.9 liters or 55 cubic inches.
– Cylinder Arrangement: The L98 engine features a V8 configuration, which means it has eight cylinders arranged in two banks of four cylinders each. The cylinders are positioned at an angle of 90 degrees from each other.
– Compression Ratio: The compression ratio of the L98 engine is 9.5:1. This ratio determines the amount of compression that occurs inside the cylinders during the engine’s combustion process.
– Fuel Injection: The L98 engine was one of the first Chevy engines to feature Tuned Port Fuel Injection (TPI). This fuel injection system improved fuel efficiency and power output compared to carbureted engines.
– Horsepower and Torque: The L98 engine produced around 230 horsepower and 330 lb-ft of torque. These figures may vary slightly depending on the specific model and year of the vehicle.
Engine Oil Specs & Service Intervals
Proper engine oil specifications and regular maintenance are crucial to keep the Chevy L98 engine running smoothly. Here are the recommended engine oil specifications and service intervals for the L98 engine:
– Engine Oil Type: The L98 engine requires a high-quality engine oil that meets the API (American Petroleum Institute) specification of SF or SG. It is recommended to use a multi-viscosity oil with a viscosity grade of 10W-30 or 10W-40.
– Oil Capacity: The L98 engine has an oil capacity of approximately 5 quarts, including the oil filter. It is important to check the oil level regularly and top it up if necessary.
– Oil Change Interval: It is recommended to change the engine oil and oil filter every 3,000 to 5,000 miles or every three to six months, whichever comes first. Regular oil changes help maintain engine performance and prolong the life of the L98 engine.
– Oil Filter Replacement: When changing the engine oil, it is essential to also replace the oil filter. The oil filter helps remove impurities and contaminants from the engine oil, ensuring clean oil circulates through the engine.
– Oil Viscosity in Different Climates: Depending on the climate you live in, you may need to adjust the viscosity of the engine oil. In colder climates, it is advisable to use a lower viscosity oil, such as 5W-30, to ensure proper lubrication during cold starts. In hotter climates, a higher viscosity oil, such as 10W-40, may be more suitable.
