Maintaining the correct fluid levels and specifications is critical for the reliability of the 2018 Chevrolet Traverse. This mid-size crossover SUV is powered by the 3.6L V6 engine, which is a robust powerplant designed for versatility. However, like any internal combustion engine, it requires high-quality lubricants to function correctly. The engine oil capacity for this vehicle is 6.0 quarts when changing with the filter. It is essential to refill the oil and then check the level to ensure the correct amount is present.
Using a synthetic motor oil like the AMSOIL Signature Series or Extended-Life line is highly beneficial for this engine. The 3.6L V6 is sensitive to the Dexos1 Gen 3 specification, which updated from the previous Gen 2 standard. AMSOIL motor oils are formulated to exceed these requirements, offering significant protection against Low-Speed Pre-Ignition (LSPI) and wear. Whether you drive in extreme heat, severe cold, or do a lot of city driving, the stability of synthetic oil ensures consistent performance. For owners with higher mileage, the High-Mileage option provides a unique chemistry with boosted detergents that help clean sludge and reduce oil consumption.
Filter choice is equally important. The AMSOIL Oil Filter EAO17 is designed to work in tandem with these synthetic oils. It allows for lower restriction, which keeps engine parts properly lubricated, and captures a high volume of small wear-causing contaminants. If you prefer an aftermarket alternative, the WIX XP or standard WIX Oil Filters are also compatible with this vehicle. Regularly changing the oil and filter is the single most effective way to extend the life of your Traverse’s engine.
Transmission fluid is another critical component often overlooked. The 2018 Traverse features a 9-speed automatic transmission. Using a synthetic automatic transmission fluid is vital for this gearbox, especially if you engage in heavy towing or driving in hilly terrain. AMSOIL Signature Series Fuel-Efficient and OE Fuel-Efficient synthetic transmission fluids remain fluid in sub-zero temperatures and protect against the rigors of elevated temperatures. They help prevent the transmission from slipping and maintain shift quality over long service intervals, protecting your investment against costly repairs.
Beyond the engine and transmission, other fluids play a vital role in the vehicle’s overall health. The cooling system requires a high-quality antifreeze to prevent corrosion and maintain optimal operating temperatures. The capacity for the cooling system varies slightly depending on the specific configuration, ranging from 15 to 15.3 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant and AMSOIL Propylene Glycol Antifreeze provide extended protection for up to 150,000 miles or five years, safeguarding gaskets, hoses, and metal components from damage.
The differential and power steering systems also benefit from synthetic lubrication. The rear differential requires a specific capacity of gear lube, which can be topped up with AMSOIL SEVERE GEAR 75W-90. This synthetic lube controls thermal runaway and protects against rust, ensuring the gears engage smoothly. For power steering, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps seals remain soft, preventing leaks and ensuring quiet operation, even in extreme temperatures.
Finally, brake fluid is essential for safety. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers a stable viscosity across a wide temperature range, ensuring your brakes respond reliably. It can improve ABS and traction-control responsiveness, giving you better control during emergency stops. By using a comprehensive package of AMSOIL products, you address the needs of every lubrication point in your 2018 Chevrolet Traverse, ensuring smooth operation and long-term reliability.
About the Vehicle
The 2018 Chevrolet Traverse is a mid-size crossover SUV that represents a significant step forward for the brand’s lineup in the family hauler segment. Built on the GM E2XX platform, it was designed with a focus on versatility, offering a spacious interior that can comfortably accommodate up to eight passengers depending on the trim level and seating configuration. The 2018 model year, in particular, is celebrated for its refinement and the inclusion of the robust 3.6L V6 engine, which provides a healthy balance of power and efficiency for a vehicle of this size.
Powered by the 3.6L LGY or LFY engine code, the Traverse delivers a smooth and confident driving experience. This engine is a naturally aspirated V6 known for its durability and ability to handle towing duties without straining. Owners often appreciate the vehicle’s ride quality, which manages to absorb road imperfections effectively while maintaining control during cornering. The interior is spacious, featuring high-quality materials and a user-friendly infotainment system that was well-regarded for its time. The design team at Chevrolet focused on maximizing cargo space, making the Traverse an ideal choice for families who need to transport gear, sports equipment, or large loads regularly.
While the Traverse is generally a reliable vehicle, there are some common issues that owners of this specific model year should be aware of. One frequent problem is the excessive oil consumption that some 3.6L engines exhibit, particularly as they accumulate mileage. This can lead to low oil levels if the owner does not check the dipstick regularly. Using a high-quality synthetic oil like AMSOIL can help mitigate this issue by providing better film strength and seal conditioning, which can reduce the rate of oil consumption over time.
Another area of concern for Traverse owners is the cooling system. Over time, corrosion and buildup can occur in the cooling passages, leading to overheating issues. The engine is sensitive to temperature spikes, and maintaining a clean, high-performance cooling system is crucial for preventing head gasket failures. AMSOIL antifreeze and coolant products are designed to exceed OEM corrosion standards, helping to keep the cooling system clean and efficient for the long haul.
Additionally, some owners have reported issues with the transmission, specifically regarding the 9-speed automatic’s shifting behavior or fluid degradation under heavy loads. The transmission fluid can break down faster than expected in severe driving conditions, leading to harsh shifts or slippage. Switching to a premium synthetic transmission fluid can provide better stability and protection against wear, potentially extending the life of the transmission and improving shift quality. Finally, there are cases where the power steering system can develop leaks due to seal degradation, especially in older vehicles. A synthetic AMSOIL power steering fluid that is designed to condition seals and resist heat can help prevent these leaks and maintain steering precision.
In summary, the 2018 Chevrolet Traverse is a capable and well-loved family vehicle. By understanding its specific needs and addressing its common vulnerabilities with high-performance synthetic lubricants, owners can ensure that their vehicle remains a reliable and enjoyable part of their daily lives. Proper maintenance with the right fluids not only extends the vehicle’s lifespan but also enhances its performance and driving dynamics.
The 2018 Traverse is a testament to Chevrolet’s engineering, offering a blend of comfort, capacity, and performance. Whether you are commuting through city traffic or hitting the open road for a family vacation, this vehicle is built to handle the demands of modern life. With the right care and the correct AMSOIL lubricants, your Traverse will continue to perform at its peak for years to come.
