Realizing the increasing price of gasoline ... Just want to start a poll to see which grade of gasoline most people use on their TL. I am sure the most popular one would be the premium grade 'for now' ... but I can totally see myself use the plus or even regular grade near the end of my lease ... :thefinger

 

93

 

92 Chevron and the prices are still rising.

:tflamer: gas

 

93 + a bottle of Techron every 3k since Chevron is not available in MI.

 

93 in my area is only between 5 and 7 cents more than Plus (89 octane). For 5 to 7 cents a gallon I would rather no loose HP by having the engine computer alter the engine timing to accomodate the lower grade fuel I use.

Using 86 or 87 will nor ruin your motor, so why would you put it in at the end of your lease ?

If you want to save a couple of bucks a month after each full tank of 93 put in a few galllons of reg, the result will be a 90 or 91 octane mix and you may save a bit. Never tried it but it should be ok, since the car requires 91 octane

 

Hi,
I usually put 50% of 89 and then fill the rest with premium, i have not noticed a significant performance degradation and it saves a bit of money. Although, premium gas is $1.59 where I live, much better than some of the other states.

 

Dips009, premium is 1.59 in Philly ? I'm in Pittsburgh and its like 1.80.

What's up with State of PA??

Please. Here in Northeastern Ohio, premium is over $2; I paid $2.04 the other day.

But, you know, anything to keep my car happy!

 

Using Mobil Super 92. Currently $1.79/ga here but because of the substantial improvement in mileage over my previous car, it's costing me less per week for gas than I was paying.

 

I read somewhere that octane will not mix, so putting two different octanes in your gas tank will not result in an average of the two. Does someone have the facts on this?

 

Octanes will mix. Most Midgrades are nothing more than a blend of unleaded and premium. Depending on weather and octane/quality of the unleaded, the ratio can vary.

 

Premium is $1.79 in KY. I use it exclusively. If you want the prices to stay the way they are, don't vote for Kerry. He wants to tax gas at .50 gallon!!!

 

I always used Amoco on my last car and probably will stick with that.

Chevron is good gas??

 

I use premium, but prices are over $2 per gallon down here in Vice City.

 

We in Northern Orange County, CA. pay in the range of $2.45 - $2.50 for premium now. I expect close to $3 by mid-summer.

It's getting ridiculous...

93 of course.... premium gas In NYC/NJ area is bet 1.79 to 2.01

 

And it's 91 octane. Everyone else is getting 93. :rocketwho

 

93 only. I just bought at my friendly neighborhood BP for $1.96 last PM ("1.95-9")

 

The role of octane is to slow down combustion. It is not a more is better situation. How much octane you need depends on the amount of oxygen molecules in the air where you live, which is mainly dependent on your elevation. That is why different areas of the country have different octane ratings for their gasolines. your not getting jyped on anything but the number printed on the pump.

 

Live in Phoenix and use 91 from Sam's Club where I get a much better price on it than with normal gas stations: 209, versus 225 at most regular pumps.

However, a little off-topic I know, but some people have been telling me that the quality of gas that Sam's Club and Costo has is sub-standard. I haven't had any problems with mileage on the car, nor any other problems with the way the car runs when I use this gas. Does anyone have any evidence that their gas is not as good as say 76, or Texaco gas?

Thanks...

 

I had a friend that worked as a buyer for Wal-Mart / Sam's and he said that basically Wal-Mart buys from the lowest gas distributor. They basically buy the cheapest stuff on the market. He said that quality controls were only as good as the vendor. Basically, you never know what you are getting from them.

 

I paid 2.38 a gallon for Plus at Chevron (90) in Placerville, CA the other day.

 

Why do you run 93 octane gasoline when 91 octane is the recommended fuel?

 

OMG you lucky non-Californians! i would love to see gas under $2 lol. i use Mobil 91 $2.31/gallon

 

Although I am not EluSiOn, I would like to point out that premium fuel is what is recommended. Premium AKI (also refered to as octane) ratings vary by location for the reason I described above. Chances are Acura used a value of 91 in the manual as the minimum recommend generic value due to the fact that it is most likely the lowest AKI one would find for a premium fuel in the States. Look at your fuel cap. It says PREMIUM. In EluSiOn's area premium is 93. Therefore he or she uses is.

BTW I'm not trying to whore the thread, but the lack of knowledge about fuel being displayed in this thread is bothering me and I feel the need to try and educate some of you a bit so you can make more informed, and hopefully better, decesions.

anyone who doesn't use premium please return your car to the dealer. j/k =) seriously the manual says to put 91 or higher. why would you try to save a couple of bucks.

 

How do you know that 91-92 octane fuel isn't available in that person's area?

Fuel octane ratings also vary by BRAND (in the same area). I can buy 91 octane, 92 otane, 93 octane or 94 octane within a 5 mile radius of my home, depending on which station (CITGO, SHELL, MOBIL, SUNOCO, etc) I choose to visit. And in many cases, the same BRAND (e.g. Sunoco) markets the same octane fuel (albeit with location specific chemistry) nationwide.

91 octane fuel is all the TL requires; anything more than that is a waste unless 91 isn't available.

 

I didn't say it wasn't availible. It is probally the mid-grade gas.

As for the TL only neededing 91, believe what you must. I think it needs premium. Whether it be 92 (almost all brands) or 93 (only Holiday that I know of) in MN, or 91 in some areas of the Dakotas and elsewhere, I'm going with whatever the station is selling as their premium gas with their highest AKI value.
The extra 99 cents per fillup is worth it to me.

 

It needs 91.

Period.

If that's the "mid grade" then so be it.

 

The question of what octane to use is really not an easy question. I live at altitude (lowest point is 5000 ft and my house is at 6000 ft.). At this altitude, they don't even sell anything higher than 91 octane. As someone mentioned already, the reason for higher octane is to limit the combustibility of the fuel to prevent pre-ignition. At higher altitudes, this is not a problem since there is not enough oxygen for this to happen (this also means a reduction in HP). I believe most engines today can detect pre-ignition and compensate for it. However, this does reduce the performance of the engine. I am a firm believer in using what the manufacturer recommends (even if it is overkill). I worry that if I don't, there is a possibility the manufacture will blame the fuel for engine problems and not cover them under warranty. So despite my statements that premium is not needed where I live, I still use it.

 

Anyone running @ those kinds of altitudes is the exception rather than the norm. I'd still probably run 91 octane @ that altitude, even though 89 would probably work just fine.

Anyone running 93-94 octane in their new TL at an altitude that remotely resembles "sea-level" is throwing money away.
