I have been trying to find any gas stations in the Mississippi,and Louisiana area that sell gas with a higher rating than 93. As a matter of fact I would love to find 94. If anyone in the MS or LA and even in some of the southern states have used or know of any gas stations, please post back here and include the city, state and gas station name.

thanks

Unless your'e running boost, higher than 93 octane is a waste of money.

 

I use to run Sunoco 94... shell 93 feels 10 times better in my car..

 

76 has higher octane stations but none in my area ...still looking

 

saw 106 at a bp in georgia

 

would you mind telling us why you want 94?

you can also buy 91 and an octane boost... sounds like it would be easier than finding a station with higher octane.

 

i'm originally from netherlands, europe, currently in louisiana. lowest octane rating sold in holland is 95. driving a saab 9-3 turbo didn't make a damn difference what kinda of octane rating went in there whether 95 or 98. just thought i'd share...

yeah, but dump 87 octane in it and see what happens.

 

thanks for the input ..

 

I've seen higher octane grades in gas stations in local towns along Cape Cod shoreline.. my guess is that its for boats

The other place I've see higher octane grades are in racetracks/dragstrips.

I've never found a place in Kansas that sells over 91 octane

 

unless you're running boost I still can't see why you'd want anything higher than 91 (in the owner's manual).

anyone? Or I should say, anyone who's not running boost?

 

I wouldnt waste your money on that expensive of gas, regular premium is good (from 91-93). That high of octane is only needed for big power applications ie: Kev with the boost up

 

Fuel octane levels in Europe are rated differently than they are in the US. Your 95 octane is rated via the RON method, which is a higher number. The other number, MON, is about 8 to 10 points lower. In the US, the octane ratings are the result of averaging these two numbers. So...

95 RON => ~89 US
98 RON => ~93 US

 

Shell 93 feels considerable better than Sunoco 94 for you?
Hmm...
Maybe I'll have to try Shell 93 again...

 

Amoco/BP carries 92 everywhere in Kansas City. That's where I always buy from. Even though it won't do anything for you, 100 octane is available at the Citgo gas station off of Mission Road just east of Shawnee Mission North High School.

you can mix gas to get a higher rating.

a mechanic at the dealer ship i worked at showed me how.

 

yeah but who would actually go through that trouble?

 

sometimes it may be cheaper to mix gas.

for boosted guys or people with high performance motors people may be detonating. well you can find the perfect mixture to end the detonation. 2 guys at the dealership that i work with mix gas for there cars. one of the guys has a built nova. the other guy owns a se-r with a fully built sr20det.

for example:

Maxima 16 gal. Capacity

We will mix 91 and 102 octane fuel.

If we use a 1:1 ratio we will come up with the octane rating will be 96.5

This is how we come up with this number.

16 gal. Total cap.

8 gal. Of 91 octane
8 gal. Of 102 octane

8(91) = 728 <=========Take these 2 # and add them.
8(102) = 816 +

1544<====== Divide this number by the total tank capacity.

1544 / 16 = 96.5 <=========This is your octane rating.

91 octane 8gal@ 2.25 (socali) = $18
102octane 8gal@ 4.50 (socali) = $36
$54 dollars

or you can buy 100 octane out off the pump at 4.99*16gal=$79.84

$54 dolla or
$79.84 to fill up a tank what would you pick.

especially if all you needed was 96 octane to keep from detonating.
a full tank off 100 octane would be a waste.
of course you would first need to have the problem off a daily driver that is detonating. we maximas don't really have this problem. but keep playing with your daily driver and you will run into this problem.

 

Couldn't you just do (91+102) / 2 = 96.5 (since you're putting equal parts of each octane).

 

i used that for an example

yeah thats a simple 1:1 ratio it will work out that way. try using your way with 6 gallons of 91 and 10 gallons of 102 use your way and give me the octane rating of your tank of gas.

you may need to go with 94 octane or you want to make 98 octane.
maybe you want 105 octane so your gonna use a racing fuel with a higer octane like 110 or something you play with the numbers. i used the the 1:1 ratio to make it easier to see how the formula works out.

 

Yes, you're right The non 1:1 ratio would be
[(6x91)+(10x102)] / (6+10) = 97.875

Instead of the 1:1 ratio: [(8x91)+(8x102)] / (8+8) = 96.5

I was simplifying it for a 1:1 ratio because the equation can be changed to [(8x91)/(8+8)] + [(8x102)/(8+8)] = 91/2 + 102/2 = (91+102)/2 = 96.5

Ok, enough math for the rest of the week

 

you see i suck @ss in math and algebra
espiecially word problems so there you have it the formula in mathmatical terms

 

down in new orleans theres a station that sells 100 octain fuel but i cant remember the name of it off the top of my head.... also a few places in Baton Rouge.

 

now we are talking

...if you find out a station in street in baton rouge or new orleans remember to message me and let me know...thanks

 

uhhhhhh....why waste the money on 100 if you don't need it??(assuming you don't) are the already crazy $2.00 gas prices for 91 too cheap for your blood??

 

your profile doesn't say anything about boost... we're still wondering why you want octane higher than 91 (nissan recommended). Are you having detonation issues or knock/ping?

 

Ok, with all these octane ratings above 93 (which I happen to use on my boosted Max from Shell, Exxon, Texaco on those save 9 cents Tuesdays), is there anything wrong with going with an all out higher octane like those numbers above like 96 and up, is that good for the catalytic converter?

-Ben

 

are you detonating on the 93 octane??????

if not your fine.

the reason why my parts guy is mixing fuel is because we have 91 . and even with a jwt ecu and 550 injectors blah blah blah he still gets detonation. he found that 97 octane i belive stoped the detonation. and its cheaper for him to make a tank of 97 octane rather then flling up with 100 octane.

 

No. Get past "scooter" and "swami" and this explains it well

yes like i said higher octane is used to help fight detonation.


good article by the way..

I doubt I'm getting any detonation on 93, I have the 1-step colder plugs gapped to about .031 and I checked them recently and look normal, and I recently dyno-tuned my a/f ratio to 12.1:1-12.3:1 across the board to make sure I wasn't running lean on top end. Is it possible to still get detonation from just using 93? Every now and then I would fill up the tank with 93 and use the Preston Octane Booster (orange bottle that claims to up the octane rating by a few points) and on that tank, my car didn't seem to be as hesitant, but then again it could be psychological since I just spent $5 on that bottle. I recently set the knock monitor function on my S-AFC2 and I'm still learning how to read knock, but I'll see if another tank of 93 and that booster reduces the knock count. What do you think?

im interested to see how the safc 2 is working out.
