I was comparing the specs of 2005,2004 and 2003 Honda Civic Coupe on the Jonda site (in the model library) and one thing which I noticed is that it says 2004 Civic coupe takes "Premium Unleaded" while for 2005 and 2003, it was "Regular Unleaded". Is it an erroneous data on thier website or is it correct?

 

welcome to the forum, according to the Honda sites, Edmunds, Internetautoguide.com all show the 2004 civic coupe using unleaded regular. Even the si model with the K-20 uses regular unleaded.

 

I verified the spec portion of Honda Civic coupe 2004 at honda official site and it still says that it takes Premium. It might be an error on the website else if we have an user of this car, kindly confirm

confirmed your site, american honda, called customer service, they viewed the 04 civic owners manual, shows regular unleaded, they mentioned that it might be a type-o error on their internet sight, they will look into it and get it corrected. So all civics 04 use regular unleaded. They said thank you for looking to varify. Good eye, good find.
