I will mention that at time of purchase, the salesman, service manager, and a mechanic all stated that we would be "OK" using regular and would not violate any warranty conditions by doing so but might notice a slight degredation in performance.
For the record, I'm not wet behind the ears exactly: In the 70's I worked at a sportscar dealership and have owned a 61' Jag, 60' MGA and today still own a 72' MGB. In the "old days", I remember recommending people use a minimium Sunoco 240 - 260 preferred (102 octane). My MG manual states to go no lower than 93 octane - 95 recommended, leaded no less. Gone are those days and I manage with 91 octane and lead substitute.
Not looking to argue - just allay fears. The manual does in fact recommend Premium ..... they also recommend changing the brake fluid every 12 months.
At my last fill up Premium was out so I used Regular for the first time in this car. Personally noticed zero difference in the way it drives and as a bonus mileage has gone up 2 mpg. Seriously, all the drama here about junking engines, sacrificing your juke, voiding warranties is very entertaining. I'm an Automotive Engineer. You are not going to do any such thing. I've owned "premium recomended" cars before (BMW's, Mini Cooper S, Aurora) and used regular often with no detrimental consequences at all. I'm not about telling you what to do; it's totally owners choice. However if you wish to, and it works for you, you can feel totally comfortable feeding your Juke regular and disregard the hysterics.

Cars these days have sophisticated computer control systems that make fuel octane a non-issue. Obiously the lower grade will not get you the optimum power you want, but you arent going to notice any loss of power.
Lately i have been filling up my juke with 87 and not one problem, nor feeling of loss of power. still peppy since the day i brought it home and its not even time for its first oil change yet.
my fuel economy has not changed either
hmmm...It kinda begs the question as to why Nissan would recommend the use of premium at all if it makes no difference huh? I know!...Must be a damn conspiracy going on between them and the big oil companies ...right?
