octane booster

[trimup]

You have to know how to read the marketing hype 10 numbers is one point. This stuff will make 87 in to 88. Klotz Kl-450/1 or Hitrate is the product to buy. 1 quart added to 10 gallons of 86-87 R+M/2 octane donkey pee trail gas makes usable 92-93 R+M/2 this is lab tested not anecdotal nonsense, but if you like anecdotes we run it without issues in our Turbo ETEC sleds that will and do melt pistons right now on pump 89 or 90. You can run it in higher concentrations and/or with better base fuel for higher octane appilcations. 5 gallons is $80-100 depending on supplier and shipping or about $5/qt.

So right now:

10 gallons base fuel $20+ $5qt Hitrate =$2.50/gal which is almost as cheap as good non-oxy premium.

For higher octane needs 100LL around here is running $3.50/gallon and good 92 is $2.35

5 gallons 100LL $17.50 + 5 gallons 92 $11.75 + 1 gallon Hitrate $20.00 = $4.50/gallon

for a pretty darn good facsimile of 108 octane race gas.

Keep in mind that the oil you use can dramatically affect the observed octane in a premix application or one where the oil injection pumps oil into the fuel before it goes through the fuel delivery system. The vast majority of two stroke oils reduce the knock resistance of even low octane pump fuel. The only oil I have ever seen data on that does not reduce octane even in race gas is Motul Grand Prix.

Where can you purchase Aces in Canada? I have tried this Klotz product. Has anyone else used it?

As far as I know no Canadian dealer. Last time I purchased it was from Todd at Hydromotive. See mrcrsr hear is also a dealer.

#1 Can you support this claim with any followup documentation?

#2 ... you just claimed that you could boost up 92 and 100LL with 10% Hitrate to significantly increase octane with 10% Hitrate ... how would 4% oil significantly decrease the same fuel? Are you using 4% oil (25:1) or 3% (32:1)? If the oil is that bad for octane, no one would ever use more than they needed to and factories would have used less rather than more in their race motors.

1) I didn't pay for tests so the results are not mine to share. Even if I had paid I don't think I would dare share as the karting concern that did pay just casually mentioned to a leading two stroke oil seller at a weekend race that their flagship product had had a negative effect on the AKI of the reference fuel. The karting concern got a letter from the Oil Co's attorney on Wednesday demanding they cease and desist bad mouthing the product in question or face litigation.

2) Well all oil has to do to reduce the octane of any given fuel mixture is exhibit lower anti-knock properties than the mixture. Maybe it isn't obvious but anything we add can have only one of three effects: increase the octane of the mixture, decrease the octane of the mixture or have no effect( say if we add 92 octane fuel to 92 octane fuel). Hitrate increases the octane of unleaded pump fuel because it is substantially a couple of very high octane hydrocarbons ending in ene and tetraethyllead. The -enes exhibit the linear effect on octane with respect to amount added we would expect to see with any hydrocarbon, and then TEL does the rest of the heavy lifting in Hitrate.

I suspect that decsions made about perentage of oil to run or recommend are driven by a need to stave off lubrication related failures and effect on octane of the fuel mix takes a back seat.

EGT will also be affected by the oil you use and how much.
Thoughts on KL-100 in reference to octane change by % used?

My point is that the amount of oil being added is almost negligable in total fuel ratio ... 2% or 4% and at that, its octane is NOT ZERO.

I'd love to see some numbers from a scientific test

Cast your gaze wider it only takes a few grams per gallon say .5 percent by weight tetraethyllead to boost the octane of most pump fuels 12 full points. TEL doesn't even have an octane rating hy itself as it is not a combustible hydrocarbon. I suspect there are metallic anti-wear additives in some of the oils that are highly effective octane reducers. Also remember there are hydrocarbons that have negative octane ratings, Hexadecane for example is -30. Obviously small amounts of anything with a negative octane rating will have an outsize effect.

DIdn't think you could find TEL in a can for public use these days.

That's why I use Aces. if you need to go up more that 4 points, probably should be running race fuel or looser heads.

Find me the evidence that ANY 2 stroke oil contains such a chemical and I will agree.

[Mark75H]

Come to think of it ... if there was any 2 stroke oil that significantly reduced octane ... wouldn't the outboard manufacturer's warn against using that oil?


Wouldn't they say using the oil voided the engine's warranty?


If oil in general decreased octane, wouldn't there be a big warning about using too much?

[rude tim]

The plan is to get twin 300xs, send the boat to the island where 91 octane is not avaliable but 87 and keep adding Aces IV, is this a good idea? how reliable is Aces IV? What it shelf life? Will Mercury void warranty?
other option would be to go with Verados 300, add additional almost 400 pounds on transom, spend over 10k extra for motors cost and rigging...

For this setup i would suggest Toluene. You can pick up a gallon at most ACE Hardware Stores. If you can get them to sell it in bulk it will get cheaper. Toluene does not raise the octaine much but it stops detonation. I use 1/2 gallon to 15 gallons of gas, you can use more if needed. You can check out how it works by putting it in a newer car that is computer controlled. The computer sets the timing by the knock censor located on the block. My S10 would smoke the tires when I added it to my tank. Refineries use this for a base fuel to do their octaine test. F1 use to use this as fuel back when the first generation of turbo engines were used back in the day.
