Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See Scheduled
Maintenance (page 324).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts (page 292).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.
