When I bought my 2011 Nissan Juke SL FWD on 2/3 from ABC Nissan on Camelback Rd in Phoenix, the dealership insisted that I ONLY use Premium fuel in my Juke. I've been reading the forums on a couple sites and I'm hearing people are using even regular unleaded and with no problems?
However, the service guys said if I didn't use Premium 91 Octane or higher (if available) that my car would knock... and potentially hurt my new vehicle... should I just take this as a suggestions and start saving 20 cents/gal on gas and put regular unleaded in or continue to use the premium stuff? What about alternating mid-grade and premium? I'm very curious to hear your opinions, because I've been using ONLY premium for the last 2.5 weeks...
Right now, my MPG gauge says im averaging 21.4MPG... this sucks!! I do a lot of city driving, but I'm starting to miss my Stratus R/T Coupe that was averaging 27/28mpg... of course i'm hearing from a lot of people this is related to "break-in" period and "winter fuels"?
Any suggestions or thoughts on these questions would be great appreciated!! Thanks!! -Mike
