What octane do you use?
 

Althought premium is recommended, what octane do you use?

Re: What octane do you use?
 

For optimum performance (meaning max hp) 91 octane is recommended. Anything above 87 is ok. You will lose a little performance with 87, but will not hurt the engine nor diminish gas mileage.

Let the purist rants begin, as per the umpteen other threads on octane.

i am ussing 87 right now, i wish i had 91 around here but it goes from 87-89-93 ($.20 cheaper).. well you know i wish we had it like in europe 98 oc.!! as super and 95 as regular..


edit.: there is a "sheetz" gas station that has 91 but it is way too far..

I use 91 and feel safe with that

same here. 87-89-93. ive been using 93 but i may try 89 for awhile. if there arent any problems ill stick with 89.

i will be nothing wrong.. i might "upgrade" to 89 after a couple of tanks more once the prices go down again..

93 here...I might downgrade to 91 for a tank and test it out.

As far as I remember in Europe - or Germany - the lowest you can buy is 91. They measure the Octane somehow different.

Europe 91 "regular" = USA 87
Europe 95 "super" ... 91
Europe 98 "super plus" .. 93

They even have 100 now.. which probably corresponds the the 95 sold in the USA.

93 always

Anyone tried 'race' gas yet???

100-114 octane???

I would be careful with which Octane you use. The way I always usnderstood it was the higher the octane, the SLOWER the burn of the fuel mixture. The lower the octane the FASTER the burn. If the fuel mixture burns too fast, damage to the engine can occur, and if the mixture burns too slow, you will waste gas, overload the catyalytic converter and actually hurt performance. And there are other issues as well including heat.

For a simplistic overview check out this explanation:

how is octanage calculated? do you know? well its the same here as there. the only diference is that there is counted by the litter while here is by the gallon..

yeah Why there is different units????

I knew that the one use in Australia is RON... we have 98, 95 and 91 RON.

Add fuel additive even get over 102 RON

Sure it will be more responsive for the 8 as a high rev engine should benefit with more RON!
