Understanding Transmission Fluid for Your Chevy Cruze

When it comes to maintaining your 2018 Chevy Cruze, one of the most critical aspects is ensuring you have the right transmission fluid. Using the correct fluid not only keeps your transmission running smoothly but also extends its lifespan. Here’s what you need to know.

Manufacturer’s Recommendations

For the 2018 Chevy Cruze, General Motors specifies the use of Dexron VI transmission fluid. This fluid is designed to meet the stringent requirements of modern automatic transmissions, providing optimal performance under various driving conditions.

Why Dexron VI?

Dexron VI is a synthetic fluid that offers several advantages over older formulations. Here are some key benefits:


  • Improved Lubrication: Dexron VI provides superior lubrication, reducing wear and tear on transmission components.

  • Enhanced Thermal Stability: This fluid can withstand higher temperatures without breaking down, which is crucial for maintaining performance in demanding situations.

  • Better Fuel Efficiency: The formulation of Dexron VI helps improve fuel economy by reducing friction within the transmission.

  • Longer Service Life: With its advanced properties, Dexron VI can last longer than previous fluid types, meaning less frequent changes and lower maintenance costs.

Specifications to Look For

When shopping for transmission fluid, ensure that the product you choose meets the following specifications:


  1. Viscosity: Look for a fluid that adheres to the viscosity requirements set by GM for Dexron VI.

  2. Compatibility: Ensure the fluid is compatible with your vehicle’s transmission system. Using non-Dexron fluids can lead to performance issues.

  3. Certification: Check for certifications or markings on the bottle that confirm it meets GM’s Dexron VI standards.

Where to Find the Right Fluid

You can find Dexron VI transmission fluid at various auto parts stores, dealerships, and online retailers. Always verify that the product is labeled as Dexron VI to avoid any mix-ups with older fluid types.

Recommended Change Intervals

For the 2018 Chevy Cruze, the general recommendation for changing the transmission fluid is every 50,000 to 60,000 miles (approximately 80,000 to 96,000 kilometers ). However, this can vary based on driving conditions and habits. Here are some factors to consider:


  • Driving Conditions: If you frequently drive in heavy traffic, tow heavy loads, or operate in extreme temperatures, you may need to change the fluid more often.

  • Driving Habits: Aggressive driving or frequent short trips can lead to increased wear on the transmission fluid, necessitating more frequent changes.

  • Fluid Condition: Regularly checking the condition of your transmission fluid can help determine if it needs to be changed sooner. Look for discoloration or a burnt smell.

Partial Transmission Oil Changes

In many cases, a complete transmission fluid change requires removing the transmission from the vehicle, which can be a labor-intensive and costly process. This is where partial transmission oil changes come into play.

What is a Partial Change?

A partial transmission oil change involves draining a portion of the old fluid and replacing it with new fluid. This method is often more practical and cost-effective for vehicle owners. Here’s why:


  1. Less Labor-Intensive: A partial change can usually be done without removing the transmission, saving both time and labor costs.

  2. Improved Fluid Quality: By replacing a portion of the fluid regularly, you can maintain better fluid quality and performance without the need for a full change.

  3. Cost-Effective Maintenance: Partial changes are generally less expensive, making it easier for owners to keep up with regular maintenance.

Statistical Justification

According to the American Transmission Rebuilders Association (ATRA), regular maintenance, including fluid changes, can extend the life of your transmission significantly. They report that vehicles that undergo regular partial fluid changes can last up to 30% longer than those that do not.

Additionally, a study by the National Highway Traffic Safety Administration (NHTSA) indicates that many transmission failures can be traced back to neglected fluid maintenance. Regularly changing a portion of the fluid can help prevent sludge buildup and overheating, which are common causes of transmission failure.

By understanding the importance of change intervals and the practicality of partial changes, you can take proactive steps to ensure the longevity and reliability of your 2018 Chevy Cruze’s transmission.
