Its not a dilemma...if you drive this car and you can verify within reason EV versus
ICE miles...it is totally ridiculous to change oil on this car at 6000 miles. In my case, at 6000 miles I will have ~1800 miles on the ICE.
Of course everyone is different and if you happen to live in a harsh area like the beach or the Nevada/Utah salt flats...then you change fluids accordingly. Or if you are intimidated by the Honda machine and threats of voiding the warranty..then by all means change the oil when Honda tells you to.
No doubt someone will chirp that its "only $50 so worth it for peace of mind". True its only $50...but to Honda that $50 translates to half a million dollars for every 10,000 Oil changes...minus expenses of course. This isn't even counting the tire rotation charges or the up-sell which will occur because folks will be afraid if they don't do that...it too will void the warranty. The money it costs a consumer is not the issue...its the principle.
The other thing to keep in mind...the ICE warranty for this car is the same as for a traditional car...5 years or 60,000...think about it...even if you use the ICE 50% of the time...that will equate to only 30,000 miles on the ICE when the warranty runs out. What are the odds a highly reputable engine made by reliable company will go belly up at 60k...never mind 30k...highly unlikely. Honda is once again the one who comes out on top.
Personally, I will change the oil when the MM comes on the first time which I have no doubt will be between 6-8k just so I can document the oil was changed per spec. Afterwards, I am going to a 15,000 mile/1 year interval using a name brand extended life oil filter and a name brand 0w-20 full synthetic, extended performance oil. I chose 15,000 because at 50% ICE usage that equates to 7500 miles which is on the low end of the industry range these days.
In the highly unlikely event something goes wrong with the ICE in the next 5 years, I have no doubt Honda will spend many dollars on lawyers to defeat me just so they can assume dominance and keep the lemmings in line.
I appreciate everyone on this forum...and I truly understand the fear and intimidation these large companies purposely communicate to the consumer. I am not critical of anyone who tows the line...I personally am tired of the misrepresentation large corporations routinely do...in this case its Honda who touts these cars as "less maintenance" etc then it proves to be false when it comes to fluid changes.
As Internet inventor Al Gore famously said about climate change...this is an "Inconvenient Truth" that most folks agree with but rarely say out loud.
Love the car...have no regrets buying the car.
