i heard that japan has got higher octane levels than here in the US.
My ? is how high is the highest and what is the lowest.

 

in the us or japan? Well the highest u can find on the pump around here is 91...but in sum places u can find 95 or 96. The lowest here is..87. In japan so i hear people dont put nething less then 96 octane in there performance cars They can go up over 110 octane...u can get it here but its not street legal. i belive the highest street legal octane is 100, which is called cool blue from 76.

 

in japan.

thats what I heard about them. Also doesnt that cool blue cost like 50 bucks per bucket?

 

i dont know about 50 bucks..i can get mine for 35 bucks. But i dont know if i would want one..seems expensiveeeee just for 5 gallons.

 

so its 105 bucks to fill up our tanks with it? thats fuc ken expensive

 

yes it is..its usually only used for when ur racing. and when ur draggin..u dont run with a full tank.

 

do racers even have full tanks? or do they get smaller ones made? i remember my friend from the bay reduced his gas tank so it fit just a little bit more gas then he needed to run a quarter mile (obviously his car isnt a street car) ;x

 

They sell smaller fuel sells that can fit in ur trunk. Of course u wont be using that car for daily driving

 

awesome

 

and how do cops know if you running a higher octane?

 

They dont know...

 

Why would they care?

 

all i know is 110 octane is illegal..i dont know how they will know though

 

The octane here in japan ranges from 93-111, at least thats the lowest and highest Ive ever came across. On base they sell crappy 89 octane, which sucks sooooo bad when you are running high boost, so I have to fill up with off base gas at least once a month to help clean out all the crap, I also have to use octane boost our my car runs like shiat.

 

Are they rated by RON or AKI over there in Japan?
