How often should the oil be changed in a ridgeline?

For a Honda Ridgeline, it's generally recommended to change the engine oil every 7,500 miles or every 12 months, whichever comes first, when using synthetic oil. If you frequently drive under severe conditions, such as towing or in extreme temperatures, you may want to change it more frequently, around every 5,000 miles. Always refer to the owner's manual for the most accurate recommendations specific to your model year.
