I use 91 fuel and live above 6000 feet over sea level. I own a 2016 XV still under 1000 miles old, it drives beautiful no complaines, but a bit more of power will be wellcome. Since I can only get 87 and 91 fuel around here, I want to try an octane bosster like Royal Purple, any advice on this matter will be wellcome, hapoy sunday.
Some forums say it is a waste of money, others say it does make a difference, others say it won't work unless ECU is modify.
I wonder if ECU is autoadjusted depending on different factors that afect engine combustion, like height and octane fuel among others.
I know my answer will come when I actually try it, I have made a research about octane boosters and Royal Purple is the one I want to try, unfortunately local autozone won't have it until mid april, so until then I can only guess.
Your own experiences will be wellcome
