What GAS do you put in your ride?

[slipkord]

You guys are friggin' crazy.  Costco 87 octane and call it a day.  Save your money, the 4-cylinders aren't optimized to take advantage of the extra octanes.

E-85 = 105 octane  

Hey i really hope you have the right fuel system and engine parts to run that because a friend of mines had to junk his engine, fuel lines, the liner in the fuel tank was eaten up, catalytic converter was shot. i forgot the rest but those are some of the problems.


I am running 87 now but i will be at 93 when i get my cars valve train upgraded and tuned this month. Finally Got the money for it all

E-85 = 105 octane  :evil:

[v6sicksspeed]

93 premium every time (v6) - i try to hit up Shell V-power as often as possible.

[thisaznboi88]

doing 87 all day all night. Not going to go higher unless I get my car tuned to it.

[NWINNIE34]

question tho..... why are our brother car (TSXs) recommended to use 91 only

since we have such similiar engines why the difference?
my buddy says his gas mileage is complete SHIT if he uses 87 but gets a ton better when using premium

[NWINNIE34]

btw i use only 87 regular.....

used premium a few times felt no difference, gas mileage was the same if i remember correctly

87 from day one.  Lots of miles on the car and no issues so far.  I don't see the value in 93 in the K24.  Rather spend the extra $$ on hookers.

The TSX uses 91+ because its CR is 10.5, hence it only making 205hp stock and being able to make boat loads more power on a 93 octane kal. Ill be running 93 octane as often as possible since all the kals I can use on Kpro are run off of RSX-S Basemap.

I have a V6 so I don't know how much the ECU's differ but, I lose about 1.64 MPG when I use 87 vs 93. I keep very detailed mileage records with an app on my phone, and The only time I fall below the average is if I use Regular instead of premium.

You are still losing money.  1.64 MPG is 27.88 miles lost on a full tank of gas (17 gallons).  I'm guessing the your mpg avg combined is somewhere around 25 - 27 (I dont know much about the v6s mpg).  Around here, 87 is about $2.25 and 93 is $0.30 more.  So, instead of eating the 1 gallon mpg loss ($2.25), it's costing you an extra ($5.10) to fill up with premium.  Not much difference on one tank, sizeable difference over the life of the car.

I'm only running E-85 for temp. I want to see how it would run on my car. I've already talked to the tuner and the shop about the E-85 switch. They say its alright, and they have done it themselves on their turbo EP3s and DC5s without changing the fuel lines. I've only put about 3 gallons to see how it would run. I will be switching back to 91 Octane (Premium here in Colorado) when I burn up the rest of the E-85. (Which will be like within the next 5 miles)

[Jeff Likes Bagels]

Forget E-85, CH3NO2 is where it's at.

V6 is a different story.  It was designed to run on either regular or premium. I remember someone saying the V6 will gain about 10hp with the 93 octane.
