EXPLANATION OF MAINTENANCE ITEMS
Engine Oil and Oil Filter
Replace the oil filter and drain and refill 
the engine oil at specified intervals. For 
recommended oil grade and viscosity,  
refer to the Owner’s Manual.  When using 
E85 fuel, your engine oil and oil filter may 
need to replaced more often. If using E85 
fuel more than 50% of the time, change the 
engine oil and oil filter every 2,500 miles 
or three months. If using E85 fuel less than 
50% of the time, follow the normal engine oil 
and oil filter change schedule (5,000 miles 
or six months). Reset the oil replacement 
reminder light (MAINT REQD) or the message
