2012 Rio EX Sedan UVO Auto/Tanzanite blue/tinted windows/Vent visors
Hi, there are so many schools of thinking on the matter that I cannot make my mind. Does someone know by experience if there are real and proven advantages of fueling with Super? I've have filled up my Rio six times with regular as of now but the last time, I treated her with Super. Am I dreaming or is it a placebo effect, I find the engine a little less raucous let's say. Checking the AVG fuel, it reported for the very first time 5.6L/100km Eco On on highway. City driving marks at 6.8L/100km. Before I was all the time between 7.2 and 8.1. Are there some Rio owners here that treat their baby with Premium gas? OK, manual says fill with regular. I'd prefer in a way since it's cheaper. Can Premium hurt the engine ore make it so fussy that I could not revert back to regular gas? Thanks for helping and sharing.
