why in the online manual does it say "Unleaded gasoline, Pump octane number of 87 or higher "?....what benefit would running the mid range gas other than the costs?....just wondering why Honda puts that in there?

The simple answer is that 87 octane is not available in every location in the USA.
There are some places that 89 is the lowest octane available.

If your lucky and can find a gas station that sells NO ALCOHOL gas you will see at least a 10% improvement in gas mileage

Here is a site to help you find stations that sell no alc. gas

thanks for info....mileage is not a problem as I am just grasping at straws for this Oil Dilution issue,,,,I have seen the oil after my first change and it was thinner than water....though maybe Honda knew about the issue and was hinting to run more octane.............winter is going to come again.....


Edited..just got back from getting gas and very little sticker said 10% alcohol ,,,,you really had to look for it....and I will check other gas station around here to see if I can find one with no alcohol

Going to 100% gasoline from E10 does not result in a 10% efficiency increase. Since Ethanol isn't just inert (it's ~80% the energy content of gasoline), changing it out for gasoline would result in about a 2% efficiency increase.

Wonder where those special "no alcohol" refineries are? :headscratch:

I am very pleased with how it runs on 87. I might venture higher some day, but can not see any urgency.
It makes no difference whatsoever, neither performance nor fuel economy improves with higher octane. The 1.5 is tuned for 87, any higher octane is superfluous as it can't adjust to higher octane without an aftermarket tune.

Simple ..... all refineries produce gas with no Alc. They add Alcohol after the gas is made
Yep the Alcohol and Octane enhancer are added to the finished product. It all comes out of the refineries the same.

You'll be looking for a while for straight gas.
The car's computers are also set for 87 octane, I've never had trouble finding 87.
