Just went to the dealer and had my first oil change done at 5K miles. It looks to me that the schedule calls for every 5K from here on out. That seems a bit frequent for synthetic oil in a hybrid. My last Hybrid (Honda Civid Hybrid) "maintenance minder" was triggered by factors in addition to mileage and called for oil changes in the 7-8K range.

What's the consensus here?

 

When using synthetic, Toyota has an unofficial 10K mile OCI, but some vehicles may call for others. The printed maintenance schedules typically indicate 5K miles regardless.
