2.4L Tigershark oil consumption, and the XB1 warranty extensionmajor
- 2.4L Tigershark I4
The 2.4L four-cylinder uses oil between changes, sometimes badly. This is not folklore: Chrysler published a warranty extension coded XB1, under Warranty Bulletin D-23-01, for 'Select 2014 - 2019 Jeep Cherokee (KL)' and a list of sibling Fiat Chrysler models. Its own description of the symptoms is 'oil pressure low indicator lamp illumination between oil changes' and 'excessive oil consumption,' and the procedure is 'performing an oil consumption verification test and possibly replacing the long block.' Six separate revisions of a companion bulletin, '2.4L Engine Oil Consumption Test,' appear in Chrysler's filings for these years. Owners in the community report engines replaced under warranty after failing that test, and report stalling when the level runs low. The coverage terms are not stated in the bulletin summary, so verify by VIN rather than assuming it is still live. On any 2016 2.4L, check the level on the test drive and ask for oil-change receipts close enough together to tell you how much it drinks.
