Octane Level for 2017 Honda Civic Touring Sedan
 

Hello -

I recently bought a 2017 Honda Civic Touring Sedan. When purchasing the vehicle, the dealer told me it took 87 octane gasoline. However, the owners manual says all vehicles with a 'Sport' mode take 91 octane. What confuses me is every Civic for my generation from the EX-T trim level and up uses the 1.5 liter I4 engine with a turbo - would all of them require 91 octane? Or is it just the Civic Si and the Civic Type R? Please help clarify this for me because I want to take proper care of my vehicle, but I also don't want to waste money on octane I don't need.

Thank you in advance!

welcome to the forum. octane depends on what engine you have, if it is the normal 2,0 lower horsepower engine, 87 octane. if it is the high performance high horsepower engine or turbo engine, use 91 octane. try to avoid engine knock.
