2012 Mitsubishi Eclipse oil FAQ

Which engine configuration applies to my vehicle?

Use the door jamb sticker, owner's manual, or engine cover badge to identify your engine, then match it to the engine options listed above.

Is the oil capacity measured with or without the filter?

Capacity condition matters. With filter includes a new filter. Service fill is the typical drain-and-fill amount. Dry fill is for a fresh empty engine only.

Why should I confirm before buying?

Retailer catalogs can update separately. Confirm the exact 2012 Mitsubishi Eclipse selector at checkout before you buy.

Do I also need to match the OEM oil approval?

Yes. Viscosity is only one part of the oil spec. Match the oil approval listed in your owner's manual or on the bottle before checkout.

How often should I change the oil on a 2012 Mitsubishi Eclipse?

Change intervals vary by engine option for this vehicle. Always follow your owner's manual and oil-life monitor. Severe service may require a shorter interval.

Do I need a new drain plug gasket?

Replace it when your vehicle uses a serviceable gasket or crush washer. Confirm the gasket size and drain plug torque from the service manual or parts counter.
