Premium is considered 93 around here, 91. can i use "mid"

vince1128 · 05-15-2008, 08:46 AM

I was reading the gas mileage thread and it seems like people pay for premium in some places that is only 91 octane. In North Carolina, 93 is considered premium 91 is mid. Can i use 91 safely? it would save a few bucks and iit doesnt seem like it hurts any of you

In Kansas (and other parts of the country) Premium is 91. I believe the owners manual says it's the minimum, so you should be ok...

If you have an Si you can use 91. That is the minimum. Some stations here in FL offer 91 and 93... then again they are only about 3 cents apart so I pick 93... but I have put 91 before and it works fine. Read your manual, it states 91 is just fine.

How about filling half the tank with 93 and half with 87 or 89(mid where I am)? Anyone tried?

You are cheap.

As long as the final octane rating comes out to 91 or greater you will be fine, but it seems like a waste of time.

91 octane is considered by all automakers to be premium fuel nowadays. If a car calls for premium it's designed for 91. I'm not sure why we still have 93 on the east coast.

to save what? a buck, maybe two? Not worth it and would just be extra time you have to spend at the pump...

first of all buddy it doesnt work like that..... there are to many variable that varies octane content of the gas is not just simple math..

dont BUY an SI if you cant afford 91 octance of higher to run your si on

not hatin but sayin

chanchan · 05-15-2008, 11:23 AM

LOL Gas is sooo expensive right now where I live (Ontario, Canada).

$1.25 / L premium usually has a 10-12 cent premium, I pay $1.30+ / L

A tank is running me $55-$60 now .. x___x it's gonna be more expensive than my parents Camry soon!

bilzfan · 05-15-2008, 11:24 AM

Actually, it does work that way. I have a friend whose father owned a Sunoco station a very long time ago. Sunoco stations used to have many different octanes available from the same pump simply by rotating a selector on the side of the pump. All it did was change a combining valve that pulled different ratios of the highest octane with the lowest.

I've have made a habit of putting 93 octane in when the tank is close to empty. I top it with 89 when I need less than half a tank, and I know the last full fill from empty was done with 93.

I have never experienced knocking, and my milage is not affected negatively.

I have been driving Hondas probably since before most of you were even born. My first was a '75 Civic with a CVCC engine (3 valves per cylinder to reduce pollution).

Blending is perfectly fine. Yup, I saved all of 60 cents on my last fill from one half of a tank, but there is nothing wrong with doing it.

Yup, that's how every station does it, 2 tanks, one for premium, one for regular. Ever look at some pumps and see a high and low rotating counter kind of hidden further down from the display? it just counts out units of high and low octane gas dispensed. Midgrade gas isn't it's own blend, it's just a blend of high octane and low octane fuel.

btw mid (plus) is usually considered to be 89 so its kinda off a bit for use as a premium substitute.

Duce2k · 05-15-2008, 11:44 AM

I only see 93 around here in TX, I never really noticed 91

voodoophantom · 05-15-2008, 11:51 AM

What I would give for $2.50 a gallon at the pump again.......

Why do some gas stations sell only 93 and not 91? Is it an issue of where you live or what gas station you use? If I know a particular gas station sells 91 and it's not out of the way I would use it, but in Indiana I have yet to come across a station selling 91 where I live.
