those 3 links have been posted before. they all have a lot of errors in them. read how the octane points system works. you can contact a fuel company like chevron as they are the most helpful, they will point out the fact it goes by .10 not by 1.0 as those articles show. you can even find that info on the back of some bottles in small print
