I've got an s300 in my lude which i am very happy with, still learning so i'm in the playing with it stage. My question is how do i take advantage of 98 octane, i've heard you shouldn't advance your spark anymore than you have to but i want to know how much is to much, should i just advance it untill it pinks and then pull it back a little?

 

you iwll do best to tune for 98 octane on a dyno, you can see detonation on the dyno charts long before you will hear it.

 

How much is 98 octane? I know here 93 is $2.65 and 110 is $3.99

 

i'm from the uk and its about £1 a litre, mybe a little less. i think at the minute thats close to $1.85 per litre.

price of fuel is **** over here, you buy a high performance car and shell out for the high insurance then you try to buy the highest quality fuel you can to protect your engine and they charge £1 a litre, i live in scotland, we produce more oil than any other european country and we pay more for our fuel, it sucks. anyway back the question, can i take advantage of my higher octane by advancing my igntion or is that the wrong way to go?

 

here in Cyprus we have 95, 98 and 100 oct fuel and the prices are from 0.59 to 0.63 cy pounds/litre. Have in mind that $1 = 0.45cy pounds (about)
