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 2019 GMC Sierra 3500 HD 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 2019 GMC Sierra 3500 HD?
Use the oil-life monitor or the interval in your owner's manual for this engine. Severe service can
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.
