TIP: Refer to the owner’s manual for cold temperature operation oil viscosities.

For more information on the appropriate engine oil for a particular engine application, check the Approximate Fluid Capacities section and the Fluid and Lubricant Recommendations section under the Maintenance Items link at the top of the Service Category Type page in the appropriate Service Information. (Fig. 26)

The Maintenance Items link also provides quick access to information on GM Oil Life System resetting, tire rotation, air filter replacement, spark plug replacement, brake pad inspection, and other common maintenance items.

    Chart says 8.0 quarts of oil for a L8T engine with filter. On first oil change drained and added 8.0 quarts of oil with new filter and the level on the dip stick was barely in the cross hatch area on the stick ? Is it possible the stick isn’t the correct length? Or the capacity doesn’t include the filter?

  2. Hello,

    Would there happen to be oil capacity reference charts around going back farther than 2012?

    Thank you!

  3. The 6.6L L8T engine uses 5W-30 oil. The chart has been updated. Thanks for the feedback.

    Can you please confirm the correct oil viscosity for a 2020 Chevrolet Silverado, 6.6 L v8 RPO L8T ? The 2020 TECH LINK oil chart indicates that it should be 0w-20. The oil cap indicates that it requires 5w-30
