It does seem that for some the MM calls for oil changes long before overall time or ICE operation time/milage would warrant. It almost seems like it’s using total miles instead of HV miles.
However in my case of low miles ~4,200 in 6 months and an 85/15 EV/HV split, it’s calling for the oil change at 11 months which seems reasonable. But that may be because my total miles are so low that it’s timing out at 1 year or ~8,000 total miles.
I have researched as much as I can on the oil issue. What I’ve found is that Honda used to specify that the Factory Fill (FF) oil not be change early since it was beneficial in breaking in the engine. However now all Honda says is to “avoid full throttle starts and rapid acceleration” (Honda.owners.com) when engine is new and says nothing about oil change frequency other than following the MM.
On the Honda tech forum (not official
Honda) the consensus is that there is no special break in oil used. However the assembly lubricants used have a large mount of molybdenum additives that mix with the FF and make it like a break in oil with additional properties. This may be why Honda used to say don’t change the FF early.
Bottom line is just using any quailty oil that meets Honda’s viscosity and API requirements and following the owner’s manual will be fine. That means a synthetic or semi-synthetic since that’s all you can find in 0W20.
Since the first oil change has to be with in 1 year now matter how low the miles on the ICE, I will use the Honda full syn (rather pricey IMHO) since it has been reported (but not verified) to have a higher moly content that their synthetic blend or Mobile 1. But that’s because I will only have ~500 miles on the ICE by then . After that, it’s whatever I can find on sale.
