I use 87, mainly because it's cheap. My 4Runner runs the best with 87 anyway, might have something to do with the elevation.

 

87 and when I clean my Fuel Injectors 91.
Santa Barbara's 87 is freakin' $1.97!!

-Stu.

 

87 at ~ $1.65

 

Canada the 87 is $0.78 per liter or about $3.12 PER GALLON!!!!

I use 87 BTW

 

and I thought it was expensive here......That remindes me, when I drove an expedition to Mexico, it would take $55 to $60 dollars to fill one tank!

 

I don't know if my feeling is wright, please correct me if I am wrong.

I try both Regular and Premium. On Regular, I notice I had a better acceleration and seems stronger; however the engine roaring a bit louder on acceleration phase. On Premium I have better gaz mileage (16mpg vs 15mpg), I loss the acceleration / power. When I hit the gaz pedal to pass another car, the truck seem to take more time than when I am on regular ; however, the engine seems to roar a bit less than on Regular. May be my ears aren't as accute as they are used to and need to be check up.

 

the gas is just playin mental games on ya. need not worry

 

i use 89 all the time, switching to 91 or 93 every once in a while.

89 and 87 are pretty close in price in these parts, so i dont see why i shouldnt opt for the higher octane.

my one question is, i got this truck with 47K or so on her, and never bothered to ask what octane the person before me used. does it matter that i didnt find out??

what if theyd been using 89, 91 or 93 all the time?? what are the consequences?

 

89 to reduce ping and slightly better mentally noticed performance...

89 because... well just because.
