Service bulletin BTS160705

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

"TECHLINE SUMMARY ARTICLE - SOME CLIENTS MAY COMPLAIN THAT THE LOW OIL PRESSURE INDICATOR COMES ON, REQUIRING ENGINE OIL TO BE ADDED, WHILE OTHERS WHO ROUTINELY CHECK THE OIL LEVEL AS RECOMMENDED IN THEIR OWNER’S MANUAL MAY FIND THAT OIL CONSUMPTION HAS EXCEEDED THEIR EXPECTATIONS. IF YOU GET A VEHICLE IN YOUR SHOP FOR AN OIL CONSUMPTION CONCERN, BE SURE TO RUN AN OIL CONSUMPTION TEST USING THE ENGINE OIL CONSUMPTION TEST JOB AID IN SIS. IF THE OIL CONSUMPTION IS EXCESSIVE, AND YOU’RE NOT NOTICING ANYTHING MECHANICALLY WRONG, THE PISTON RINGS MAY BE CLOGGED FROM CARBON BUILDUP."
