Understanding Your 2018 Chevy Cruze Engine Options
The 2018 Chevy Cruze was offered with a couple of different engine choices, and it’s vital to know which one powers your vehicle, as this dictates the specific oil capacity and type required. The two primary engines available in North America were:
1. 1.4L ECOTEC DOHC Turbo I-4 (Gasoline): This is the most common engine found in the 2018 Cruze, known for its balance of fuel efficiency and performance.
2. 1.6L ECOTEC DOHC Turbo-Diesel I-4 (Diesel): A less common but highly fuel-efficient option for those seeking diesel power.
Each of these engines has unique requirements, making it crucial to consult your owner’s manual or check your vehicle’s specifications before purchasing engine oil.

Key Details: 2018 Chevy Cruze Oil Capacity and Type
Let’s break down the specific oil requirements for each engine variant.
1.4L ECOTEC DOHC Turbo I-4 (Gasoline)
For owners of the gasoline-powered 2018 Chevy Cruze, these are the specifications you need:
Oil Capacity: The 1.4L Turbo engine typically requires 4.2 quarts (approximately 4.0 liters) of engine oil when performing an oil and filter change. It’s always a good practice to start with slightly less than the full capacity, then check the dipstick and add more gradually until the oil level reaches the “FULL” mark.
Recommended Oil Type: General Motors (GM) specifies the use of SAE 5W-30 full synthetic engine oil. More importantly, this oil must be dexos1™ Gen 2 certified. The dexos1™ specification is GM’s proprietary standard, ensuring the oil meets stringent requirements for engine protection, fuel economy, and emissions control, especially for turbocharged engines to prevent low-speed pre-ignition (LSPI). Using a non-dexos1™ certified oil can potentially void your warranty and lead to engine damage.
1.6L ECOTEC DOHC Turbo-Diesel I-4 (Diesel)
If your 2018 Chevy Cruze is equipped with the diesel engine, its oil requirements are distinct:
Oil Capacity: The 1.6L Turbo-Diesel engine has a larger capacity, requiring approximately 5.3 quarts (approximately 5.0 liters) of engine oil with a filter change. As with the gasoline engine, always confirm the level with the dipstick.
Recommended Oil Type: For the diesel variant, GM recommends SAE 5W-30 full synthetic engine oil, but it must be dexos2™ certified. The dexos2™ specification is designed for diesel engines, taking into account their unique combustion characteristics, higher soot production, and the presence of diesel particulate filters (DPFs). Using an oil not meeting this standard can compromise the DPF and lead to costly repairs.

Why The Right Engine Oil Matters
Engine oil is the lifeblood of your vehicle. Using the correct 2018 Chevy Cruze oil capacity and type is not just a recommendation; it’s a necessity for several critical reasons:
Lubrication: Oil reduces friction between moving parts, preventing wear and tear that can lead to premature engine failure.
Cooling: It helps dissipate heat generated by friction and combustion, preventing engine components from overheating.
Cleaning: Engine oil carries away contaminants like sludge, varnish, and metal particles, keeping the engine interior clean. The oil filter then removes these particles.
Sealing: Oil forms a seal between the piston rings and cylinder walls, helping to maintain compression and power.
Corrosion Protection: Additives in the oil protect metal surfaces from rust and corrosion.
Using the wrong viscosity, a non-synthetic oil when full synthetic is required, or an oil that doesn’t meet the specific dexos certification can lead to reduced fuel economy, increased engine wear, premature component failure, and issues like LSPI in gasoline turbocharged engines.

Checking and Changing Your Engine Oil
Regular oil checks and timely oil changes are fundamental to engine health.
Checking Your Oil: On a level surface, with the engine warmed up and turned off for a few minutes (to allow oil to drain back to the pan), pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again. The oil level should be between the “ADD” and “FULL” marks. If it’s low, add the specified oil type in small increments until it reaches the full mark.
Oil Change Intervals: For most 2018 Chevy Cruze models, the oil change interval is dictated by the vehicle’s Oil Life Monitoring System, which typically suggests changes every 7,500 to 10,000 miles or once a year, whichever comes first. However, driving conditions (e.g., heavy city driving, extreme temperatures, towing) can shorten this interval. Always follow your vehicle’s specific recommendations and pay attention to the oil life monitor.

Choosing the Right Oil Brand
When selecting engine oil, focus on the specifications (SAE 5W-30, full synthetic, dexos1 Gen 2 or dexos2 certified) rather than just the brand name. Many reputable brands like Mobil 1, Pennzoil, Castrol, and Valvoline offer oils that meet GM’s dexos standards. Look for the “dexos” logo on the oil bottle to confirm compliance.

Conclusion
Understanding the 2018 Chevy Cruze oil capacity and type for your specific engine is a cornerstone of responsible vehicle ownership. Whether you have the 1.4L gasoline or the 1.6L diesel engine, using the correct SAE 5W-30 full synthetic oil with the appropriate dexos certification (dexos1 Gen 2 for gasoline, dexos2 for diesel) and maintaining the correct oil level will significantly contribute to your Cruze’s longevity, performance, and fuel efficiency. Regular checks and timely oil changes based on your vehicle’s oil life monitor are small investments that yield significant returns in engine health and peace of mind.
