speeds during hot weather, above 90°F (32°C)

If equipped for and operating with E-85 (ethanol)
fuel.
If ANY of these apply to you, then change your engine oil
every 3,000 miles (5 000 km) or 3 months, whichever
comes first, and follow the maintenance recommenda-
tions in “Maintenance Schedule B.”
If none of these apply to you, then change your engine oil
every 6,000 miles (10 000 km) or 6 months, whichever

tervals exceed 6,000 miles (10 000 km) or 6 months
