I have both a Honda Accord Hybrid Touring 2020 and 2021.  Not happy with the 19 inch wheels on the 2021 lost about 5 miles per gallon was averaging almost 50 miles per gallon even 52 miles per gallon on the 2020 when I drove it nicely.

Is the dilution factor an issue on these vehicles?  I asked the dealer to look to see if the fuel injectors are in place on beneath the cover and they said they were and there was only a solenoid and no high pressure device to inject the fuel.  This was the parts department telling me this I just wanted to verify with you if this is true or not.   The one main reason I buy the Hybrid is because of the transmission which is what they call an ECVT its really not even close to a CVT is more closer to a Transaxle rather than a transmission with only gears (planetary gears etc) sharing the same Honda Regular Automatic Transmission ATF Fluid and not any CVT fluid at all.  The dealer put in CVT fluid twice in my 2015 caught it each time did not damage it but ended up trading it in.

Anyhow enough of that can you comment on the Earth Dreams oil dilution issue for the Honda Accord Hybrid 2015/2017/2018/2019/2020.  They skipped 2016.

Thanks
