Greetings, my wife and I just bought a new RAV4 Hybrid and got the 50,000 service plan with it. The service plan covers oil changes every 10,000 miles but they said if I want it done every 5000, which they recommend, they will do the labor for free and I just need to purchase the oil. Walked over to parts and asked them what the Toyota 0W16 cost per Qt and they didn't even have it in stock. Turns out service dept uses bulk Phillips 66 oil. Not a mainstream oil around here but its what a popular distributor around here carries. Not much info out there about it but I think it will be fine. Man this thing just sips the gas.
Honda uses Phillips 66 as their OEM oil and it is also repackaged and sold as Red Line's "Professional Series" OEM standard oil. It is a perfectly serviceable product. I have a friend who went over 10,000 on his OCI using this stuff in a Honda HRV and the vehicle's MM was only down to 15%.
