Capacity by Engine Option

Oil Change Interval

Chevrolet recommends using the vehicle's Oil Life Monitoring System (OLMS) to determine the ideal oil change interval. Under normal driving conditions, this typically translates to intervals of 7,500 to 10,000 miles or 12 months, whichever comes first.

For vehicles driven under severe duty conditions, such as frequent short trips, extensive idling, towing, or very dusty environments, the OLMS may recommend more frequent changes, potentially as low as 3,000 to 5,000 miles or 6 months. Always consult your owner's manual for the most accurate information and follow the OLMS recommendations.

Drain Plug Torque

The oil drain plug for both the 1.5L LFV and 2.0L LTG engines on the 2018 Chevrolet Malibu typically requires a torque of 18 lb-ft (25 Nm). Always use a new crush washer with each oil change to ensure a proper seal and prevent leaks. The crush washer is a single-use item and should be replaced every time the drain plug is removed.

How to Change the Oil

1. Warm up the engine: Drive the vehicle for a few minutes to get the oil to operating temperature, ensuring better flow.
2. Lift and secure: Safely lift the front of the vehicle using a jack and support it with jack stands.
3. Locate and drain: Place a drain pan under the oil pan, then carefully remove the drain plug to allow the old oil to drain completely.
4. Replace filter: While the oil is draining, locate and remove the old oil filter. Apply a thin layer of new oil to the gasket of the new filter before hand-tightening it into place.
5. Reinstall drain plug: Once drained, reinstall the drain plug with a new crush washer and torque to specification.
6. Add new oil: Lower the vehicle and add the recommended amount of new, specified oil through the oil fill cap.
7. Check level: Start the engine and let it run for a few minutes. Turn it off, wait a few minutes for the oil to settle, and then check the oil level with the dipstick. Top off if necessary.
8. Dispose of old oil: Properly dispose of the used oil at an authorized recycling center.

Common Issues / Tips

• Low Speed Pre-Ignition (LSPI): Both the 1.5L and 2.0L turbo engines are susceptible to LSPI. Using the correct Dexos1 Gen2 (or newer) approved oil is crucial to help prevent this phenomenon, which can cause severe engine damage.
• Oil Consumption: Some 1.5L engines have been known to exhibit higher than normal oil consumption. Regularly check your oil level between changes, especially if you have the 1.5L engine.
• Turbocharger Longevity: Using the correct oil and maintaining regular oil change intervals is vital for the longevity of the turbochargers in both engine options.
• Oil Filter Housing: Be cautious when removing and installing the oil filter, as overtightening can potentially damage the plastic oil filter housing on some models.
