well... ive been driving my SS-III (which i assume has the 3S-GE engine) for over a year and a half now, and only recently did i realise that the petrol cap says "ONLY HI-OCTANE FUEL"... and ive been using regular the entire time...
is that like... really bad? is it worth changing to hi-oc from now on? (ps. when i first got the car my japanese wasnt so good, so it took me a while to actually be able to read that warning  so im only half a retard...)

Yup. Pretty much the same. It's just rated differently.
My first post pretty much explains what happens when you run a lower octane fuel. It can cause damage but the knock sensor does it's best to prevent that. If you run the higher octane fuel, your ECU will restore the timing back to where it's supposed to be and you'll probably see an increase in performance... that is, if the knock sensor did it's job. --------------------  Project ST204.5 99.88946% complete... |
