The 2018 Chevy Cruze uses several filters, with the most common being the engine oil filter, the engine air filter, and the cabin air filter. For the engine, the oil should be Dexos1 Gen 2 rated, typically 0W-20 in many configurations, but always verify with your owner's manual or GM guidance for your exact engine and climate.
Engine oil filter
What it is and where it sits
The engine oil filter on a 2018 Cruze is a cartridge-style filter housed in a metal canister on the engine. When you service the oil, you replace the filter element and the O-ring gasket, then refill with the correct Dexos1 Gen 2 oil. The exact oil grade can vary by engine variant and market, but 0W-20 synthetic is common for many models.
What you need to service it
If you’re planning a DIY oil change, gather these items before you start.
- New engine oil (as specified for your engine, typically Dexos1 Gen 2 0W-20)
- New engine oil filter cartridge (GM-approved or equivalent)
- New oil filter O-ring/gasket
- Tools to remove the old filter and drain the oil
- Oil drain pan and rags
After replacing the filter and adding fresh oil, reset the oil-life monitor and dispose of used oil and the old filter properly.
Engine air filter
What it is and where it sits
The engine air filter sits in a rectangular panel inside the engine bay’s airbox and cleans incoming air before it reaches the intake. Replacing it helps maintain engine performance and fuel efficiency. The Cruze uses a standard disposable panel filter, with replacement intervals typically in the 30,000–40,000 mile range under normal conditions, and more often in dusty environments.
What you need to service it
For a DIY air-filter change, you’ll generally need:
- New engine air filter of the correct size
- Basic hand tools or a screwdriver if needed to open the airbox
- A clean workspace to avoid introducing dirt into the intake system
Ensure the airbox is properly resealed after installation to prevent unfiltered air from entering the engine.
Cabin air filter
What it is and where it sits
The cabin air filter cleans the air entering the interior through the vehicle’s HVAC system. In the Cruze, it is typically located behind or near the glove box. Replacing it improves HVAC performance and helps reduce odors and pollutants. Typical replacement intervals are roughly 15,000–25,000 miles, but environments with higher pollution or dust may require more frequent changes.
What you need to service it
For a DIY cabin-filter change, gather these items:
- New cabin air filter (proper size and orientation for the Cruze)
- Basic tools if the access panel or glove box needs to be opened
- Instructions or a guide to ensure correct orientation of the filter
After installation, test the HVAC system to ensure good airflow and no debris in the cabin.
Transmission filter note (if applicable)
What to know
Some 2018 Cruze models with automatic transmissions have an internal filter within the transmission pan that is serviced as part of a transmission fluid service. This is not a routine DIY filter replacement like the engine filters and is typically handled by a dealership or a qualified shop. Always consult the owner’s manual or a GM service guide for your VIN to determine if a serviceable transmission filter exists on your specific configuration.
How to identify the correct parts for your VIN
Because filter compatibility can vary by engine variant and market, use your VIN when shopping for parts. Check the owner's manual or consult a trusted parts retailer to confirm the exact filter size and Dexos oil specification for your exact Cruze configuration. OEM options from GM’s ACDelco line or reputable aftermarket brands (Bosch, Mann, Wix, etc.) are commonly used and widely available.
Summary
A 2018 Chevy Cruze typically requires three main filters: an engine oil filter (cartridge style) paired with Dexos1 Gen 2 0W-20 oil, an engine air filter, and a cabin air filter. Replacement intervals vary by filter type and driving conditions: oil and filter roughly with each oil change, air filter every 30,000–40,000 miles (dusty areas shorter), and cabin filter every 15,000–25,000 miles, with adjustments based on environment. For exact specifications, always consult the owner’s manual or a dealer/parts professional using your VIN.
