Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What is the fuel capacity and recommended fuel type for the 2017-2019 Buick LaCrosse?

The 2017-2019 Buick LaCrosse has a fuel tank capacity of approximately 15.6 gallons. The recommended fuel type is regular unleaded gasoline with an octane rating of 87. However, for optimal performance, using gasoline with an octane rating of 91 or higher is suggested, especially for drivers who frequently carry heavy loads or drive in hilly or mountainous terrain.

Q2

What are the maintenance requirements for the fuel system?

Regular maintenance for the fuel system includes inspecting fuel lines and connections for leaks, cleaning the fuel injector every 30,000 miles, and replacing the fuel filter every 15,000 to 30,000 miles. It is also recommended to avoid using low-quality fuel and to keep the fuel tank at least a quarter full to prevent moisture accumulation.

Q3

How do I replace the fuel filter?

To replace the fuel filter, start by relieving the fuel system pressure by disconnecting the negative battery cable. Locate the fuel filter, typically found along the fuel line near the fuel tank. Use a filter wrench to loosen and remove the old filter. Install the new filter by hand tightening it in a clockwise direction. Reconnect the negative battery cable and start the engine to check for leaks.

Q4

What are the common causes of poor fuel efficiency?

Common causes of poor fuel efficiency include driving habits such as rapid acceleration and braking, underinflated tires, faulty oxygen sensors, or clogged air filters. Additionally, using the wrong octane fuel or carrying excessive weight can also decrease fuel efficiency. It is recommended to have your vehicle inspected by a certified technician if you notice a significant drop in mileage.

Q5

How can I optimize the performance of my Buick LaCrosse?

To optimize performance, ensure proper tire inflation, maintain a consistent driving speed, and avoid idling for extended periods. Regular tune-ups, such as spark plug replacements and fuel system cleaning, can also improve efficiency. Additionally, using the correct fuel type and keeping the vehicle's software up to date can enhance overall performance.
