2019 Honda Civic: is 91 octane required?

Topic starter

My Granddaughter recently bought a 2019 Honda Civic Sport.  She said the owner's manual says "Models with Sport mode require 91 octane".  Her car has the naturally aspirated 2.0L.  Any Honda Civic owner's use 91 octane?  I was surprised to learn this, especially since it is not turbo charged.

Any input from Honda owners would be appreciated.

Thanks.

I recommend re-reading the manual. Sometimes there are nuances. 

For example, it may something like, “91 fuel is recommended. Using 87 may have occasional knock but not detrimental to your engine. Using LESS than 87 will kill your engine.”  

Ok, maybe not exactly worded like this, but some nuance like this.

Owner's manual says "recommended."  I would use 91.


Good catch, Doc.
