What type of oil do I need for a 2018 Chevy Malibu?
For a 2018 Malibu, you should use Dexos1 Gen 2 synthetic motor oil. The exact viscosity depends on which engine you have: 0W-20 for the 1.5L turbo and 5W-30 for the 2.0L turbo. Always verify with your owner's manual or a Chevrolet dealer if you’re unsure.
Engine options and oil requirements
The 2018 Malibu was offered with two turbocharged gasoline engines. Each engine requires a specific oil viscosity while meeting the Dexos1 Gen 2 specification. The following guidance helps you choose the correct oil for your particular model.
Oil recommendations by engine type:
- 1.5L turbocharged I4 (most Malibu trims): Dexos1 Gen 2 approved 0W-20 synthetic oil. This viscosity supports efficiency and cold-start performance while meeting GM’s spec.
- 2.0L turbocharged I4: Dexos1 Gen 2 approved 5W-30 synthetic oil. This viscosity accommodates the higher thermal load of the larger turbo engine while staying within the Dexos1 Gen 2 standard.
Conclusion: your Malibu's oil choice depends on the engine you have. Always use Dexos1 Gen 2 certified oil in the viscosity specified for your engine.
Why Dexos1 Gen 2 matters
Dexos1 Gen 2 is GM’s required oil specification for many modern engines to ensure compatibility with GM engines and emission-control systems. Using an oil that meets this standard helps protect the engine and maintain warranty coverage, especially for turbocharged configurations like the Malibu’s.
Conclusion: choose an oil that explicitly states Dexos1 Gen 2 approval and the correct viscosity for your specific engine variant.
Tips for choosing the right oil
When shopping, look for labels that read Dexos1 Gen 2 and confirm the exact viscosity (0W-20 or 5W-30) matches your engine. If you live in extreme temperatures, you can select the appropriate Dexos1 Gen 2 oil within the recommended viscosity range for your engine, but do not deviate from the official specification.
Note: Always refer to the owner’s manual or contact a Chevy service advisor to confirm the precise specification for your VIN.
Maintenance considerations
Beyond selecting the correct oil, following GM’s recommended oil-change intervals and using a quality filter are essential for long-term engine health. Typical normal-condition intervals tend to be around 7,500 miles (12,000 kilometers) for Dexos1 Gen 2 oils, but conditions such as heavy city driving or extreme temperatures may warrant more frequent changes. Use oils and filters that meet GM guidelines and torque specs as outlined in the service manual.
Conclusion: sticking to the recommended Dexos1 Gen 2 oil and change schedule helps protect the engine and maintain warranty coverage.
Summary
In summary, for a 2018 Chevy Malibu, use Dexos1 Gen 2 synthetic oil with the viscosity chosen for your engine: 0W-20 for the 1.5L turbo and 5W-30 for the 2.0L turbo. Always confirm the exact specification in your owner's manual or with a Chevrolet dealer, and choose a product that specifically bears the Dexos1 Gen 2 designation. Regular oil changes with the correct oil are essential for optimal engine longevity.
