Oil change, how often on my 2015 Prius Plug In Hybrid?

I'll keep trying to find out. I came close today. I had gone about 115 miles w/o the engine before it started today due to exceeding my battery capacity. If the appointment this morning was about 2 miles closer, I'd have made it on battery and then not needed the engine till the weekend.

With the PiP, I could never come close to even thinking about going 124 miles in all EV. Today, my round trip for this errand was 38.5 miles, but ran out of battery at 36.1 miles. Grrrr!!

 

You can drive a plug-in without ever plugging, always in hybrid vehicle mode? I think Toyota has to consider this, set oil change interval for worst case.

That said, I think yearly or 10K miles is already pushing it, lol.

 

True. That said I guess its too technical for Toyota to expect someone driving a PiP to consider %EV
