Doing this with it being cooler out, may be fine now. But when it gets hot again, this may not fly.
Using a lower octane than what is recommended, will cause the knock sensor to pull timing when it sences detonation.
i did this before a while back and actually heard a little knocking/clicking, just to see what would happened, so i went back with 93, it used to only be 20 cents more a gallon the 87, but now wow, i was at a 7-11 last night that has the five grades 87 88 89 91 93 the 91 was 7 cents higher then the 89 im not dare going to say the 93 price.
this is what im think about of course i know your not going to recommended it, but i was thinking of getting 89 and adding octane booster this stuff is home made and i will have to mix it myself, i used it before in another truck and nothing every happened, i was mainly talking about mixing in achol but it states not to go over a 20% ratio. but im not sure if i will save anything in the end. this was my other ideal, was every other time i get gas, alternate between 89 and 93 that making sure theres more 93 and that should gave me a 91-92 mix and maybe save me a little money. i forgot its a little colder here in fl, wonder if it gets any colder if i could run 87 lol not going that low.
oh just to let you know and others that last time i checked the mpg in the city was 17 and hwy was 20-22 not one point i did get 20 city. course i driving a way to make sure i got 20.
