The 2018 Chevy Traverse oil capacity and type are critical pieces of information for any owner looking to maintain their vehicle’s performance and longevity. As a popular mid-size SUV known for its spacious interior, comfortable ride, and reliable performance, the 2018 Traverse is a significant investment for many families across North America. Proper engine oil, in the correct quantity, is the lifeblood of your engine, ensuring everything runs smoothly and efficiently for years to come.
Understanding the specific requirements for your Traverse’s engine oil is not just about following a manual; it’s about protecting one of the most vital and expensive components of your vehicle. Using the wrong oil type or quantity can lead to decreased fuel economy, premature wear, and even severe engine damage, which can result in costly repairs down the road.
Why Engine Oil Matters So Much for Your Traverse
Engine oil performs several essential functions within your Traverse’s powertrain:
Lubrication: It creates a thin film between moving parts, reducing friction and preventing wear.
Cooling: Oil helps dissipate heat generated by friction and combustion, preventing engine components from overheating.
Cleaning: It carries away dirt, sludge, and other contaminants, keeping the engine’s internal components clean.
Sealing: Oil helps create a seal between the piston rings and cylinder walls, preventing combustion gases from escaping.
Corrosion Protection: It protects metal parts from rust and corrosion, especially during periods of inactivity.
Given these vital roles, it’s clear why selecting the precise oil capacity and type recommended by Chevrolet is non-negotiable for the 2018 Traverse.
Engine Options for the 2018 Chevy Traverse
The 2018 Chevrolet Traverse offered two distinct engine options, and their oil requirements differ significantly:
1. 3.6L V6 Engine: This is the most common engine, offering a balance of power and efficiency suitable for most driving needs, including towing.
2. 2.0L Turbo I4 Engine: Available exclusively on the RS trim, this turbocharged four-cylinder engine provides a sporty driving experience with impressive torque.
It’s crucial to identify which engine your Traverse is equipped with before purchasing oil or performing any maintenance. This information can typically be found on your vehicle’s window sticker, owner’s manual, or by checking the VIN.
Oil Capacity for Your 2018 Chevy Traverse
Knowing the exact oil capacity ensures your engine receives adequate lubrication without being overfilled, which can be just as detrimental as underfilling. These capacities are specified assuming an oil filter change is performed concurrently, which is standard practice during an oil change.
For the 3.6L V6 Engine:
The 2018 Chevy Traverse equipped with the 3.6-liter V6 engine typically requires 6 quarts (5.7 liters) of engine oil. It’s always a good idea to add slightly less than the full amount initially, then check the dipstick and top off as needed to ensure the level is within the recommended range.
For the 2.0L Turbo I4 Engine:
The 2018 Chevy Traverse RS model featuring the 2.0-liter turbocharged four-cylinder engine requires 5 quarts (4.7 liters) of engine oil. Due to the precision requirements of turbocharged engines, ensuring the correct capacity is even more vital.
Always confirm the exact capacity with your owner’s manual, as minor variations can sometimes occur, or check the specific engine code details.
Understanding Oil Types for the 2018 Chevy Traverse
Beyond capacity, the type of oil—specifically its viscosity (weight) and specification—is equally important. Chevrolet has stringent requirements to ensure optimal engine protection.
Recommended Oil Viscosity (Weight)
The viscosity of oil refers to its thickness and how easily it flows at different temperatures. It’s indicated by a two-number code (e.g., 5W-30). The “W” stands for “winter,” and the first number indicates the oil’s viscosity at low temperatures, while the second number represents its viscosity at normal operating temperatures.
For the 3.6L V6 Engine:
The recommended oil viscosity for the 3.6L V6 engine in the 2018 Chevy Traverse is SAE 5W-30. This grade offers excellent cold-start protection and maintains stability at high operating temperatures.
For the 2.0L Turbo I4 Engine:
For the 2.0L Turbo I4 engine, a lighter viscosity oil is specified: SAE 0W-20. This ultra-low viscosity oil improves fuel economy and provides faster lubrication during cold starts, which is particularly beneficial for turbocharged engines.
Crucial Oil Specification: dexos1™ Gen 2
Regardless of the engine, the most critical aspect of the oil type for your 2018 Chevy Traverse is that it must meet the dexos1™ Gen 2 specification. This is a proprietary standard developed by General Motors to ensure superior engine protection and performance.
What does dexos1™ Gen 2 mean?
Enhanced Protection: Oils meeting this standard offer improved protection against engine wear, particularly in demanding conditions.
Turbocharger Specific: For turbocharged engines like the 2.0L I4, dexos1™ Gen 2 is crucial because it provides superior protection against Low-Speed Pre-Ignition (LSPI). LSPI is an abnormal combustion event that can severely damage turbocharged engines. The dexos1™ Gen 2 standard specifically addresses and mitigates this risk.
Fuel Economy: These oils are formulated to help maintain or improve fuel efficiency.
Reduced Sludge & Deposits: They are designed to keep the engine cleaner by preventing the formation of sludge and harmful deposits.
While many oils on the market are labeled “full synthetic” or “synthetic blend,” it is imperative to look for the official dexos1™ Gen 2 logo on the oil container. This ensures the oil has been tested and certified by GM to meet their rigorous standards. Using an oil that does not meet this specification can void your warranty and potentially lead to engine damage, especially with the 2.0L Turbo engine.
For optimal protection and performance, particularly with the 2.0L Turbo, a full synthetic dexos1™ Gen 2 approved oil is highly recommended. While some synthetic blends might meet the standard, full synthetics generally offer superior temperature stability and wear protection over longer drain intervals.
Checking and Changing Your Oil
Checking Oil Level:
Regularly checking your oil level (at least once a month) is a simple habit that can prevent major issues. For an accurate reading, ensure your Traverse is on level ground and the engine has been warmed up to operating temperature, then turned off for about 5-10 minutes to allow the oil to drain back into the oil pan.
Oil Change Intervals:
The 2018 Chevy Traverse is equipped with an Engine Oil Life Monitoring (OLM) system. This system continuously monitors engine conditions, driving habits, and climate to determine the optimal time for an oil change. When the OLM indicates that your oil life is low (typically around 0-10%), it’s time for a change. It is generally recommended to change the oil at least once a year, even if the OLM system doesn’t indicate 0% life, especially if you drive short distances frequently. Never exceed 7,500-10,000 miles or 12 months, whichever comes first, without consulting your owner’s manual for specific limitations or your dealer.
Tips for Optimal Engine Health
Always use the correct oil: Refer to your owner’s manual for the precise SAE viscosity and ensure it carries the dexos1™ Gen 2 certification.
Don’t overfill or underfill: Both can cause significant problems. Stick to the recommended capacity and verify with the dipstick.
Use a quality oil filter: Always replace the oil filter with a new, high-quality filter designed for your specific engine during every oil change.
Follow the OLM: Trust your vehicle’s onboard system for oil change recommendations.
Regular checks: Make it a habit to check your oil level and condition periodically.
By adhering to these guidelines for the 2018 Chevy Traverse oil capacity and type, you’ll be safeguarding your SUV’s engine, ensuring it delivers reliable performance and stays on the road for many years and miles to come.
