I just read in another topic that the minimum octane fuel required in the CL-S is 92. I'm going to be buying a CL-S very soon, and I live in Salt Lake City, UT. The highest octane fuel we can purchase here is 91 (premium). The different grades go like this: 87 (regular), 89 (mid), and 91 (premium). I always wondered why California has better fuel than us, but somebody mentioned to me that it has something to do with the altitude (we are up in the mountains), and that low-octane fuel burned better at a higher altitude.

Is it even safe to buy a CL-S here given the fuel conditions? I would hate to have the dealer tell me I voided my warranty by not driving to California every time I need to refuel... :-)

Also, while I'm on the topic of fuel, I've heard some of you mention that you can get special 100 octane fuel to use for racing. Where do you buy this at?

Thanks.

The compression ratio of a CL-S requires 92. Period. 10.5:1 is a super-high compression. The manual even says that you should use Name Brand gas..because of the additives. The only thing for you to do is to stock up on octane booster.

****in Utah... Not only do we have salt on our roads half the year, we get sub-standard gas to destroy our cars. I always use Chevron Premium but I still haven't found a place that sells 92 octane fuel here.

Anyone know how safe octane boosters are? I try to stay away from additives, most of them do more harm than good.

91 octane is not a problem because it is premium (in your area).

page 160, 2nd column of the cl-s manual:
"Gasoline
Your Acura is designed to operate on premium unleaded gasoline with a pump octane of 91 or higher."

also on the inside of the back cover:
"Service Information Summary
Gasoline
Premium unleaded gasoline, pump octane number of 91 or higher."

it does state to use gasoline with detergent additives, but even the lowest grades of most brands have additives.

moomaster, you must be looking at a different manual 'cuz mine states nothing about 92 minimum or anything about brand name gasoline.

Dudes, in Virginia, it's all 93 octane, with Sunoco offering 94 octane. I came to California and was disappointed to find only 92 octane here. Are you sure it's really only 91 octane??? Maybe they are using a different method to calculate the rating. The industry standard is R+M/2 = Average octane. Research + Method Ratings divided by 2.

PS - Does octane booster really work? Also, someone said that in the cali area you can buy 108 octane racing fuel, that might be fun

Go to yuour local small plane airport. They'll sell it to ya for about $4 per gal. Octane boosters work but aren't worth the money. The CL-S will do fine on 91 Oct. I think it has to do with the altitude and the EPA controls for the are where you are. LA has a terrible smog problem as does NY. The EC doesn't give a crap as much as California does. We got so much ground pollution it's not funny. What's amazing to me is the nnumber of septic tanks and wells in the northeast. Talk about backward!

I guess as I do pump 92 cause this is what we call premiun here... I could have been quoted requires 92! if you ready in the manual 91 then it is only 91+ that you should pump.

Someone posted to go to the local airport & buy small aircraft fuel (it is 100 octane). DO NOT DO THIS !! Aviation fuel has LEAD in it & will ruin & clog up your catalytic converter!

As to the 108 race gas. When are people going to learn that any octane higher than what your engine needs is just wasted & in some cases can result in poorer performance.

Anyone want to run JET Fuel - it is just super clean kerosene!!

I have about 14,000 miles on my CL. I have put 89 octane in the car without any problems. The acceleration seemed a bit less, but no discernable knocking. I believe the ECU on the car can adequately adjust for the lower octane and you would have no problems running it. That said, I only ran about 3 tanks and then it was back to 92 octane.

A) I was tired of paying $2.30/gal for gas.
B) I knew it wouldn't hurt the engine.
C) I wanted to see if the performance was impacted dramatically.

That's about it.

91 for premium what a rip off and I don't even think VA sells 87. may be at crown or one of those cheap gas stations. I always use 93 special from mobil or 94 if I see a sunco.

You do not need the recommend octane at your altitude. As you go up the air gets thinner, and the need for octane goes down! You will be fine with the premium they sell in Utah. The altitude difference is why you see 91 as premium in places like Denver and 93 in places that are at sea level.

i hate to tell you but your wrong, sure some cars may not see much benefit from it. But alot do, esp. FI cars. I've used 100 in my CL a few times, it gave me some pickup, but it'll probally do alot more now with the NOS

 

Read my post again "Unless your engine needs the octane..", so if your engine was modified to where the higher octane allowed the computer to advance the timing, then you might benefit from higher octane. But only an increase in comp(supercharger, turbocharger, or combustion chamber resizing) or NOX would require the higher octane. Higher octane only means a slower burn(to prevent preignition or detonation) NOT more explosive or more powerful & it don't matter a damn if it is FI or not. You may feel more acceleration by using 108, but only in your head!

well FI is supercharger, turbo, n20 so then it does need it eh?

 

I disagree with that comment.

With (4) Blizzak snow tires mounted on TL rims I made it through 15+ inches of snow last Monday afternoon.
Go here for the pictures:SNOW STORY
This car is better in snow then an SUV with all season tires mounted.
I know because I passed a couple of them stuck on the side of the road last week.

Snow tires are better then chains because you can leave them on when it isn’t snowing.

BTW....I use only Mobil Super 93 fuel.

91 octane is fine...In higher altitudes the lower octane will perform at the same level as higher octane in areas closer to sea level. no problems at All. But for those of you being cheap and putting 89 or 87 octane in your car, good luck, it will take it toll over the years. Same question on ClubLexus.com. Same reply: If you are going to spend that much on a car, why take a chance...if you didn't want to pay for gas get a FORD RUSTANG...ps don't forget to grow the mallet either LOL,

Hate to butt in, Shawn, but in California, the CHP gives you no choice. They don't care what you are driving, SUV, AWD, 4WD, or FWD. WHen they say chains required, they mean it. It's a huge ticket for every sign you pass requiring chains. That's the California law for mountain driving.

theres no snow in california

 

This board is awesome! It's great that you guys share so much information with each other, even if you do have to sort through some BS...

To summarize:

91 octane or higher is required per the Acura owners manual.

91 octane fuel burns just as well at 4500 ft. altitude as 93 octane fuel burns at sea level.

Anything higher than 93 or 94 octane is just a waste of money because you're not going to get any extra power out of your engine unless you supercharge it or something.

Thanks for all the great info guys.

sorry..just so used to 92...mrdeeno, 91 is correct...but the additives they refer to are not present in cheap gas, hence....the price.

well, where i live, we can't even get 92, we have to settle for 93...sometimes 94 when i go to sunoco.

 

I can confirm. Sunoco has 87, 89 and then makes the jump to 93 and 94. I have always used Sunoco so when I got the CL-S I started using 93.

Higher Octane does make a difference. I found "the" 100 octane gas station in Santa Monica. The gas is very expensive *and* I wouldn't buy it all the time. The car feels much quicker when I put 4-8 gallons of 100 octane in with my usual Shell Premium.
