In the manual it says use 91 or above. Does anyone use 91 or below? Will it hurt the engine or should i keep running it in 93?

 

run the top that you can find. otherwise you'll get some knocking problems.

for one trip out to california from texas years ago, I did manage to get by with 87, but not recommended. it also hurt milage. yes, hurt it.

 

If your car is stock, don't waste money going over 91.

 

where do you get 93

 

places other than california

 

Some states have higher octanes than others. Here in WA, we get 92. I feel bad for the squirrel pee that California gets for their "supreme unleaded."

 

in nj only 87,89,93,94 are available...i usually get 93....i cant stand gas prices though....im about to buy a honda insight soon and leave the s2k in the garage...getting 210-250 miles on a full tank sucks!!!!!!

 

In the owners manual it says you can use "non-premium" gasoline but performance will be affected.

 

93

 

as others have said, you wont save money running less than recommended in the long run. It'll take it's toll over the long run in terms of engine life.

 

we only have whack 91 here, wow 93 would of been nice for my integra, when i had it.

 

Here we have 87,89,and some places have 91, some 92, and some 93. Shell (and i think amaco) has 93, speedway and adminral have 92, and the rest just have 91.

 

Some places sell different octane ratings due to their altitude. So if you live in a higher altitude like Denver or something, the 91 will work just as well there as the 93 will in Dallas or some near-sea level city. Just thought I'd throw that out there.

 

Damn, sucks to be a lot of you guys. We can get up to 114 at the pump at some stations around here!

I don't buy that, especially since Indiana has crap for gas with various additives that are supposed to be more environmentally friendly. when an octane is around 93... it is actually far less than that.

 

I get 93 around me.

 

Yeah, I'm full of ****. I've lived in IN for 20 years and know of one gas station locally where I can purchase 114 octane and one in Loogootee, IN (1.5hrs away) where I can purchase 104 octane.

In Georgia, we have 87,89, 93. I have yet to see 91.

 

93 here in chi-town...

 

Lately, Union 76 unleaded 100 octane racing gas. It's almost reasonable with the price of premium up so much and the quality down.

 

I run 93, it's currently $2.07 near my house. Hopefully it will keep going down.

 

****, it was $2.39/gal for 87 oct. last time i got gas here in northern san diego county.

 

3 types of petrol here: Regular 95, Super 97, and shell have Optimax which is 98+. We do pay the equivalent of $6.95/gallon!

 

Mobil 93 octane

 

CA used to have 93, why did they lower it to 91??
