I have A 2016 NX FSPORT AND BEEN RUNNING 93 OCTANE FROM DAY 1,HIGHEST MPG FOR ME WAS 21.6, I ASSUME WE HAD TO USE PREMIUM FUEL BECAUSE OF THE TURBO, AM i JUST WASTING MONEY FOR PREMIUM ,WHAT ARE YOU GUYS USING?

 

93 octane. Premium gas. 27.7-27.9 mpg. Eco mode. Mainly highway.

 

Owners manual and the sticker on the gas door says premium required. That's what I use. Premium here is 93 octane. Mileage is mostly 24 to 25.5, mix of city and highway. Highway only is 25 to 30 depending on speed traveled. 75 mph gets 25 to 25.5 mpg.

 

Premium, daily commute, no hgwy, avg 22-23 mpg, normal mode most of the time, turbo mode occasionally.

 

Mine 2017 Fsport, using 93 octane from day one. I got 26 mi/ gal, combine( everyday use ).

 

+1 on my '16 FSport at 26mpg @ 93 octane

 

I'm on 93 octane and get 19-20 average on eco/normal driving in NYC. The best I have seen was 26.7 and that was only 1 time. Lol
