octane boosters --- any that work?
 

I read a bunch of stuff here (circa 2011 - couldn't find anything more recent) re octane boosters. At that time, the general concensus was that it was all expensive shite. At best it would do little or nothing and at worst it could hurt your engine. I'm in the midst of a tune and asked if a little more get up and go could be had. The reply was that my crap 91 octane was a severe limitation. I really don't want to go meth at this time and was wondering if there's anything new that can simply be added to a tank of gas to up my octane, without damage?

E85. Pay for the auxilary tuning and be done.

Don't think there's much corn juice in canuckistan...

if it caused a real issue, i would personally just buy some high octane gas from vp or soemthing and offset with that. i cant back up any octane boosters

I tried :dunno:

about 2 gallons of heet will boost your octane.

Methanol...or methyl hydrate as its called in Canada. Get it at RONA, Canadian tire, or Home depot in the painting section. It's about $10/gal. A gallon of that per fill up and boom, you have just boosted octane.

Thanks for input
 

Scare Dem likely had the right idea (E85 + a tune) but as Agent Orange pointed out, no "corn juice" in this neck of the woods. It appears the harsh reality is that for the present, I'm SOL, other than toting around gallon jugs of meth. On a positive note, the Freektune is getting me the max out of what's available to work with. Thanks Justin. BTW Agent_Orange, "Canukistan" was a new one on me .... I had a big f'n chuckle out of that. Thanks.

Torco is about the only one I have seen work well.

Hey Justin
 

Torco runs about $300/5 gal. jug up here. If my calculations are close at all, that means that with my low annual mileage I can get away with half of that per year. I'll likely look into it after the little "big turbo" install later this fall. Thanks for the input.

Methyl hydrate. $10 bucks a gallon.
Toluene. $150/5 gallon pail.

10 dollar bucks. What's the exchange rate on that?

If my car does not sell, this is what I am using next year instead of Sunoco 260gt

Looking to sell? What are you wanting to move on to next?

Something V8 and rear wheel drive....

Yes, join the dark side!

Some octane boosters may work, but not at the promised levels. I've tried one that did its job. They promised raising the octane number by 2 but I'm not sure if it was 2 or only 1. However, it eliminated some light knock I had without affecting power (actually the engine made a bit more power since I had no more kr).

Is WMI out of the question for you? You can raise octane and cool charge air at the same time only when needed (under boost) it will make that $10 bottle of methyl hydrate (or just meth/water washer fluid) last a lot longer and effectively control knock when you care about it.


But it isn't respectable. It's mildly terrifying. And that actually makes it quite appealing. - Mazda 3 MPS review, Matthew Jones, Top Gear.

You can put Meth in the tank (only need 1 or a little more gallons per fill-up) and get the octane boost and knock protection and lower the temps in the cylinders....

Tested! Royal Purple Max Boost Octane Booster

Would this work for you?

Boostane is another up and coming Octane Booster thats been popping up in the mustang world. They compare their product mainly against Torco and, granted it is THEIR website, the ad seems promising.

BOOSTane Octane Engineering

My road race tune is designed for 98 octane, so i think my next track weekend in December (PDS @ TWS @Code Monkey; ?) i'm going to order some of this and try it out. That 98 shit ain't cheap lol.

I have specifically tuned a couple focus ST guys on this stuff

Amazon.com: Torco Accelerator 32oz The Best Fuel Additive: Automotive

I think it is just easier to add 1 gal of meth in tank. :D I have been paying $10 per gallon for 104. :(

Some areas don't have E and in some other areas (like mine) meth can be purchased only if you present a proof of use (usually paint shops and whatever other shops that use it as thinned/diluent can acquire it). The only options left are octane boosters and denatured alcohol.

I think the pumps at MSR only go up to $9.99 for fuel cost, both 98 and 110 were $9.99. I remember that not being the case at TWS?

The pumps at TWS have no prices on them, you need to ask Denise what they charge. :D

I can back up Boostane. I've run it a handful of times. Picked up a 2 tenths in the 1/8th.

I've talked with the owner/engineer behind it, and it really is more advanced than the average octane booster--it has to do with the way the octane concentrate stays in solution, rather than falling out, like others on the market. I don't recall the specifics, but it's definitely worth your consideration.

Haven't tried it, but heard good things

I've been seeing some minor knock at WOT I ordered some torco. I'll keep you guys posted on how this stuff work

I've used Xylene in the Buick. IIRC, up to 30% with 93 pump gas yields ~100 octane. I was able to bump my boost from 15 to ~21 while running this mix.

Here's some info...
Homebrew Octane Boosters

FYI, I have never done this in the MS3.
The general consensus is that the over the counter octane boosters are worthless.

The general consensus is that the stuff you buy from autozone is useless. Torco and some of the bigger name ones are far too common, and have been around far too long, to be "worthless" i feel.

Octane Booster
 

Hi I am driving Mazdaspeed3 2009 and your question was the same I am before. I tried to experiment how to boost my car without using any gadgets, my option is to used the High Octane Booster, this is usually what I am using for my cars not Turbo Engine and it's really worked but the outcome results for my Turbo Engine in my Mazdaspeed3 was missed up.

The results after putting that High Octane Booster to my Gas tank the normal engine run was issued and Engine Check. I brought my car to the Mazda mechanic specialist and the problem was my engine sensor damaged, I let them changed I I spent $120.00

Those pesky engine sensors...
