I agree, I use premimun when I tow my tent trailer and I get bteween 10-11 Lts/100 KM. In the city driving I get 11.5-12.4 lts/ 100 KM using midrange fuel.NCtravellinman said:With both my 'Mo's, positive payback for 93 octane if solid highway driving. Around town, no significant improvement in economy from 89 to 93.
Same here, i fill up only with 87 or 89 on the murano.pb1963 said:My wifes '03 runs just fine on 87. We haven't noticed any significant improvement with 91.
AKI = Octane RATINGErik713 said:First post, but I registered to post here because I have a question.
In the book, it says no less than 87 AKI (anti-knock index)....but as far as I've researched, it looks like AKI and octane are not the same. Isn't an AKI of 87 equal to octane of 92?
Am I missing something?

AKI = Octane RATING
Octane number is not the same as rating. Octane number is divided into RON (research octane number) and MON (motor octane number). If you look on a gas pump, the octane rating is the numerical average of RON and MON. This rating is the same as AKI.
The Murano requires 87 AKI, or regular unleaded. It gets better performance on 91+ AKI, i.e. premium, but its not required.
