gas octane
around here finding octane 91 is not very common, so i end up putting 93 octane.. the manual does say 91 or higher but i wonder if using 91 is preferred over 93?
any cons to using 93 vs 91 since 91 is not widely available here?

it would be a big waste of time and a hassle switching nozzles mid-fill up, so just fill up with 93 octane
or 87 octane if you want ignition delay (slight drop in performance, which varies from engine to engine).... the rule of thumb is: if the manual says use premium, use premium. if it recommends 87 octane, there's no benefit of using midgrade or premium. if you're worried about a $2 or $3 difference per fill up and you bought a $30,000 car, you have problems.

Don't try to make 91, just put the 93 in and be done with it.

the gas stations here are retarded, they all carry different octane.
gas station one: 87, 89, 91
gas station two: 89, 91, 93
there are some stations with 91 octane but none close to my town.

whooo... low octane's in usa, in europe octane 95 is standard, octane 98 is for some 'premium' engine's. My honda dealer advices me to put in 98 because of it has some more power and it should run more economical than 95. Driving with 95 though... petrol is so expensive, €1,35 for a litre octane 95 fuel = €5,11 for a gallon = 6,15 $ for a gallon.

US uses pump octane number ^^ (R+N)/2, while the rest of the world does RON. I did some calculations for the equivalent octane numbers before. I'll search and post them up:
RON PON
98 = 93
95 = 90
91 = 86
RON PON
98 = 93
95 = 90
91 = 86

I put 89 because gas price is much much higher in Canada. I believe it is at least 2.75 a galllon to fill up with premium now.
When I go to states and see the signs with low 2.xx's, I fill up with premium and drive like I stole the car.
