Long Trip/Highway Definition

Follow this scheduled maintenance only if none of the
conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is used for trailer towing, driven in a dusty area
or used off paved roads. Use the Short Trip/City
schedule for these conditions.

Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break
down slower.
