My Service Writer AND 2 of the Hybrid Mechanics that I am allowed to speak with on occasions have all told me with the Full Synthetic Oil that 10,000 miles is a good interval to change the oil. Being my father's daughter, I cannot do it, I make my intervals at approximately 8,000 miles, give or take. I check my engine's dipstick and admittedly VISUAL inspection and smell the oil. I would like to share that since my very first oil change, I have used a TRD Oil Filter which has more structure and filtration.
Pros: good filtration, long intervals
Vehicle:
Toyota Prius
Mileage: 8000 km
