Maybe a Real Octane Booster!
 

I have been looking for a real, viable gasoline additive that I can use in my 300SX's to supplement our only 91 octane (R+M/2), non-leaded, non-ethanol gas available in Oklahoma to get to 93 (R+M/2) . I have researched most octane additives currently out there. All, in my opinion fall short. They state they can raise pump gas by "x" points of octane. Note that a point of octane is only 1/10 of an octane rating number in R+M/2 rating. So, 10 "points" only raises our 91 to 92 octane! Don't believe it just read the 'fine print" on the current offerings! Looks like the below link is the real deal! Anybody try this stuff yet?

I didn't read it all, 32oz treats how many gallons

check out boostane

Splash some 110 it smells So good!

David
I agree check out Boostane. Also the guys on S&F have been running a product called ACES. I have used it for years with no issues. One ounce treats 6 gallons.
Chris Carson and DBR both 2 stroke engine builders have tested it and said it works. It really does not increase octane but lower the combustion temp.
I can get you the number and you can speak wth him about. I do not remember all the details as it was a long time ago when I spoke to him.

RACE GAS
BLENDING CALCULATOR
2 OUNCES OF RACE GAS
WILL RAISE THE OCTANE OF 1 GALLON OF GASOLINE
4 FULL OCTANE NUMBERS (40 POINTS OF OCTANE).

Use the calculator below to determine the appropriate
amount of Race Gas to add per gallon:

1 - GALLON FUEL

Some testing that my shed some light on the snake oil. I believe the ACES IV is a good product to enhance the characteristics of gasoline and I do use it.

I thought about doing this but wasn't sure if it would be safe for my 500efi's. I use to run it in my motorcycle. And if it is ok what do u do like one gallon to a tank full.

VP C5 booster you get 3.3 double it and you can get to 8.0 But you will need a lot of timing to make it burn. not sure if its worth the retuning

2 ounces per gallon
gets you 4 points.

$29.95 for 32 ounces.

100 gal fill up of 91 would be $89.85 to get to 95 octane

Read my link from post #7. VP C-5 got 6th place in the test. If your calculations are correct for VP C-5, 4 points is 4 x 1/10 or .4 rise in octane. Snake oil? I agree with mixing race gas with pump gas, but it is a hassle. I was hoping for a silver bullet, I guess. I have been mixing 100 LL aviation gas with my 91 pump stuff because my boating is in the sticks of Eastern Oklahoma with no race gas available. The written analysis from the airport FOB stated that the 100LL was actually 110 octane this summer. I asked the FOB manager why and did not get a good answer. Any pilots out there with insight to this?

Found my answer to my AV gas question.

How would you test the octane. Is there a tool?

Certain labs have a variable compression single cylinder motor to do these tests.

Put some of this in your JDeere and cut your mowing time in half

Good question. It would be nice to be able to confirm octane, and a simpler way to confirm the presence of ethanol in pump gas.

Alot of companies sell cheap ethanol % checker's.

Again, octane is tested by just a few labs that have variable compression motors. No cheap self test for this.

Put a mark half way up on a bottled water bottle with a sharpie. Put another mark approximately 10% higher than the first mark. Fill the bottle to the first mark with gasoline to be tested then add water to the next mark. Shake, then let sit for a couple of minuets. If the water settles to the bottom, good gas. If the water doesn't settle, ethanol. Pretty cheap way to test!

We have a tester. Works really well. So far since we started checking we have not had any ethanol in ethanol free fuel.
As far as the outboards go I have tried higher octane fuel and never say any difference in performance with outboards.
Minimum is 91 and I have run 90 ethanol free with Aces IV additive for 5yrs no issues.
Anything higher than 91 is waste of money IMO for outboards unless you are running high compression heads. Is there something you are not sharing David??????:ernaehrung004:

Hey All, I was wondering whether the motor manufacturer would treat any damage due to the fuel additive as a problem. I have no experience with any of this but is it possible to damage the motor because the octane gets to high. Scorch or burn any internal components. I thought the fuel burns hotter with higher octane but once again I have no experience with Boosters of any kind and have never used them.

I don't think Mercury could identify if one used an additive in the gasoline if the fuel system is empty, except for the statement from some of the octane boosters that they leave an orange residue on the spark plugs. Higher octane just is used to control knocking (pre-ignition) from too high compression. It really does not "add" power or run hotter. Ron, I just want to have a little "cushion" in my fuel to guard against pre-ignition due to fuel degradation or just bad gas. Good to know that 91 is adequate from your experience. I wonder if the Mercury ECU is adaptive like the one in my Porsche. It really likes 93 octane, but in Oklahoma, you have to "make" it. It will run adequately with 91, but really needs 93. Will increased compression increase HP on a SX? Is it achievable? Would the ECU need a new tune? So many questions! I wish it was warmer and my F***n lake was not flooded again for the 5th time this year - I would be boating!:grinser010:

I have been running 4 Aces in my vehicles for a couple years now seems to work well doesn't color the plugs funny. Works better than some of the stabilizers I have used in the past also. My Haryey sat for about 7 or 8 months last year before starting up on second hit ran the tank out no issues.

I hear ya David. My 300x motors only call for 91 minimum and I think the 300xs is the same also. I would use the ACEs and not give it a second thought. I think more damage can occur from a lean condition from one thing or another than the octane in the fuel on an outboard. Injectors and good fuel flow is key. That is why I have added the fuel pumps on my boat. Actually thought about adding fuel pressure gauges and pyrometers again also.

If the tanks have ethanol resistant epoxy and Mother Mercury says we are good up to 10% ethanol am I going to have my OOSD card pulled for regularly using 93 octane with ethanol? I usually burn the tanks down to less than an 1/4 by Sunday so it does not sit full of fuel and pump it all out over the off season.

Check out Boostane made in west Michigan...invented by an offshore power boat racer and engine builder,----and last I knew it is even endorsed by Keith Eickert.

Boostane is (or at least was ) advertised here on OSO for the last year or 2

Boostane is becoming more and more popular in the racing industry, street cars, and among offshore performance boaters year by year.

You can also get Boostane from Keith Eickert....I found this info and small write-up on Keith Eckert's website.... kustomboltons.com

"We have been running BOOSTANE in our go fast boats and race engines for years. It's the best product on the market right now for reliability, convenience, and performance. We won't trust any other octane booster in our or customer's engines." - Keith Eickert

I guess, call me a skeptic, but the Eckert site states a 15 point increase in octane - that is 1.5 octane numbers (91 to 92.5).

I'm not real sure about introducing unanticipated chemical additives to fiberglas tanks. Seems like that has happened before somewhere, and it didn't work out so well.

Just Sayin'

As someone who is very anal I checked my 28 tanks yearly and they were perfect using Aces IV.
4+ Years.

No question, there is only one product out there that is the real deal & factually proven, and it's more than just an octane booster...BOOSTANE - :Score-101010:

Nasty - Actually, high octane fuel burns slower/longer than lower octane! That's one reason why you can run more advanced ignition timing or higher compression ratios. Here's an example that was done at a clinic I attended years ago. I think it was sponsored by Champion Spark Plugs.

Guy took a 3 foot long plexi-glass or lexan tube, sealed on one end. He placed a small amount of regular octane (maybe 1-2 oz?) fuel in the tube, followed by a small rubber ball. He then capped off the open end with his hand and rocked the tube, gas, and ball combo back and forth to atomize the fuel. Then, taking a lighter, put the flame near the open end of the tube and BOOM! . Scared the heck out of us..... LOL Big flash, loud boom. That was REGULAR gas.

Next was premium, HIGH TEST fuel. He loaded the tube with the fuel and the rubber ball, only used premium instead of regular gas. He then asked for a volunteer from the audience! No one wanted to volunteer until he pleaded with us and called us "wusses". Finally a guy that was up front stood up and took the lighter. The instructor did the same thing to atomize the fuel and had the guy from the audience put the flame to the open end of the tube. I must say we were shaking in our boots when he did that. Well.... nothing as dramatic happened with the premium. What it did was light off the gas in a very slow, controlled burn. You could actually watch the flame travel down the length of the tube. Instead of a big boom, you got a long WHOOOOOSH.

And that helps explains why regular fuel will detonate in an engine with advanced timing or high compression, but premium fuel will not. Regular fuel bangs hard and for a short duration, and premium fuel burns "softer" for lack of a better term, but PUSHES for a far longer duration. You can start your spark sooner, or use higher compression, and the fuel will still be burning as the piston reaches TDC, and continues to push the piston down on the power stroke.

It really was a cool demo, and ever since I've understood that it is a waste to use a higher octane than your engine requires. (Unless you are buying a premium fuel to get more of the cleaning agents that are more frequently used in the more expensive fuels.)

On the drag cars we run, we usually use VP fuel, C12 (112 octane), but that gets expensive.... About $11.00 a gallon at the end of last summer! :eek:

Just trying to make a helpful suggestion, and I can't say I don't blame you for being skeptical----but knowing the person who developed Boostane, I highly doubt it would be worth his effort to develope and market an octane booster that only increased the octane numbers from 91 to 92.5 (in 10ths) as you have indicated---or as other companies have in the past, but there are companies out there that would try to capitalize on such a small gain or claim and I know that is where the skepticism comes in.

Each can of Boostane has the mixing ratio tables printed on the label of each can. If you're truly curious about octane boosters, then you really need to at least visit the Boostane website even as others besides me have previously suggested.

Also, I don’t really know how old the info is, but the Youtube link you gave was uploaded in 2007. One of the other links you gave is from 2002 (as best as I can tell)….both kind of old/outdated info and Boostane was not available at that time.
