Good old 91 octane premium should get you there.

I run mine on 93 octance Sunoco most of the time, but I have a slightly elevated compression ratio. 10.4:1

You should have no problem running the 98 RON currently sold where you are.
BTW, here is a conversion chart for those who like to confuse the RON vs the (R+M/2)
that we use in the USA. Note the PON refers to (R+M/2)

Dont' waste your money.

 

Ditto that. It's not that they don't boost octane, it's that by the time you put enough in the tank to have any effect, you could have simply bought a higher grade.

One or two little cans won't add a point to the rating. You gotta add quite a bit. Read the fine print.

I am not a mechanic so this is completely subjective but I add Octane Supreme 130 (Kemco Industries) to my tank to boost the octane and I feel that there is a difference. I also have the 206 engine. It comes in 32 oz bottle and you add ounces to get the desired boost. The boost range is from 2 to 16 points depending on how much you add to your tank. A buddy with a Muira swears by it and recommended it to me. A case is fairly inexpensive and a cheaper way to add hi octane fuel. Anyway, I am sure this will spark some discussion.

 

Shush! this is a secret and you cannot tell anyone, you have to promise, now that you have promised, O.K. here it is, most gasoline is a sham and while you think your getting a higher grade the same thing is in all nozzels. Remember its a secret! additives work! Anyone can say otherwise but I have been experimenting for years and I have found that 3oz/acetone and 2oz/ xylene/ten gallons/gasoline really perks up the old gal, with better milage and cleaner running and pre-ingnition gone forever. with this magical mix add 3oz/ten gallons of some type of upper cylinder lube to keep the rings and valve guides lubed. I have used Lucas and Marvel Mystery Oil. So boys and girls choose your snake oil but use it religously and you will not have to ever have to have a major tune up again. Remember don't ever give this information out as there are way to many non-believers who will flame and detract you if you reveal any of this, promise again!

 

I use Supreme 130 in my 246 (yes you can get it in Aus).
I find the engine runs smoother and much cleaner, but at low revs it tends to pop and misfire a little.
I would certainly recommend it, but I wouldn't be brave enough to put more than 4 points of boost at any one time.

 

This is a lead additive.

Is that really a good idea in these modern, "lead is a bad thing" times?

Fron their website.

A GENUINE TETRAETHYL LEAD (TEL) gasoline treatment / octane booster Since 1921, TEL has been the original additive that (1) Boosts octane numbers, (2) Eliminates engine knock, and (3) Protects valves and valve guides. Only with TEL can you expect the highest performance in these three crucial areas.

this note about the environmental effect, IS OCTANE SUPREME-130 SAFE FOR THE ENVIRONMENT?
By adding Octane Supreme-130 to your fuel, your engine will perform better by increasing horsepower and burning the fuel more efficiently. Practically all the lead content is burned and deposited on the valves and valve seats, leaving the environment virtually lead free.


Oh, and this: 18 ounces added to 10 gallons of fuel will turn a 93 octane into a 98 octane, 30 ounces into a 101 octane, etc. Guaranteed! Due to EPA regulations this product is for off road use only

Just wondering if adding a known toxin is really the best way to go.

Wow, I went to thier site. I am really surprised you can get TEL over the counter. I thought the EPA would have put the kibosh on that. Their site says,

"Octane Supreme-130 contains a high level of genuine tetraethyl lead,(60 grams per gallon)."

So that means a quart of the Kemco additive contains 15 grams TEL. Avgas 100LL (Low Lead) contains up to 2 grams TEL per gallon, Avgas 100/130 contains up to 4 grams TEL per gallon. Street legal gasolines from the 1960s high octane heyday contained anywhere from 2-3.5 grams TEL per gallon.

The alternative if you want to break federal law with a penalty up to $10,000 is to use some avgas anywhere from 10%-40% cut with pump gasoline or use the Kemco additive. The legal way is to purchase racing gasoline and cut it with pump gasoline. Your choice of VP Racing, Rockettbrand, Elf, Trick, Sunoco, etc.

 

You have no idea what you are talking about. Gary48 advice on gasoline is absolute rubbish. Gasoline is regulated by the EPA, FTC and many other federal and state agencies. The acetone nonsense you continue to peddle has been debunked on episode 53 of Mythbusters. Also here, http://www.eng-tips.com/viewthread.cfm?qid=119611&page=1

 

Jcr is a petro-chem guy, so it is in his best interest to debunk what others have found to be benneficial, just try it yourself.

 

Yes to both; closed throttle but mainly on deceleration.
I run single contacts.

 

I'll take a look.
Thanks.
