How to Use This Spec

1

Drain old oil completely. Reinstall the drain plug and tighten to the torque listed in the owner manual.

2

Install a new oil filter and pre-lubricate the gasket with clean oil. If the part number is not listed in your manual, confirm it by VIN.

3

Add about 4.9 quarts of 5W-30 full synthetic oil first, then top off gradually.

4

Warm the engine, wait a few minutes, then verify oil level using the dipstick or in-vehicle oil level display if equipped. Reset the oil life monitor if equipped.

warningImportant Notes
  • • Always verify with your OEM owner's manual. Specifications may vary by trim level and production date.
  • • The drain plug gasket should be inspected and replaced if deformed.
