E85 can be good in some cases.  However, due to the fact that it is an alcohol, there are some inherent risks that people need to be aware of.  First off, as an alcohol it is hygroscopic (https://en.wikipedia.org/wiki/Hygroscopy), meaning that it has a natural affinity to absorb water out of the surrounding atmosphere.  That means if E85 is left for a prolonged period of time (5 or more days) there will begin to be phase separation (water sitting on top of the fuel) and subsequent corrosion.  This can be catastrophic for older vehicles with carburetors or newer vehicles without the proper fuel lines or gas tank.

There are also inconsistencies with E85 that the government regulatory body has set, that can also be VERY detrimental if being used for performance applications.  That being that E85 doesn’t always been 85% ethanol and 15% gasoline. The truth is that 85% alcohol is the MAX, and the sad fact that a lot of consumers don’t know is that there is also a minimum that the minimum required for this “E85”, as of June 2011, that fuel only needs to have 51% ethanol.  

“ASTM D5798-11 Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines” we see that the 85 in E85 signifies a maximum ethanol content of 85% with the remainder being “unleaded gasoline, gasoline blendstocks for oxygenate blending (BOB), natural gasoline, or other hydrocarbons in the gasoline boiling range.”

These inconsistencies in ethanol content and subsequent octane levels, coupled with a inevitable phase separation and the fact that E85 is 30% less efficient from a fuel mileage standpoint, our engineers don’t see it is a viable solution.

The reason why we have to put Street Legal vs Not Street Legal is pertaining to the concentration of certain active ingredients (doesn’t contain lead) that the EPA deems not legal for on road use only, when blended above 103 octane.


In order to determine the octane booster that you need, either discuss with your tuner, and know your compression and/or boost pressure. Then follow our mixing charts provide our Calculator App, above.

We have many customers that have a desire to use our products to restore lost power, increase protection, and maintain due to them being older engines.  This is common occurrence with today’s engines being susceptible to the poor fuel quality and ethanol supplementation found in our gas.  

That being said, I would recommend 1/2 can of BOOSTane Premium per full tank of 93 octane fuel.  This will bring your octane up to at least a 96 while also delivering added lubricity and fuel stabilization against phase separation due to ethanol.

You can absolutely run BOOSTane with your Water/Meth Injection or Nitrous.  Be sure to understand the octane that your vehicle is requires, and follow ourmixing chartfor the desired ratio.

If you are in need of higher octane, (using the above diagnosis charts), and do not have access to race fuel either due to cost or convenience, then an effectiveoctane booster is your best solution.  Otherwise we suggest detuning your vehicle to a lower octane to protect the engine.

BOOSTane is perfect for your jetski.  The supercharged 4cylinder engine is the same 4-stroke motor that a car would have.  Especially with a supercharger and the fact that fuel at marinas is typically a very low quality, I would recommend our BOOSTane Marine.  This has added lubricity, which our boat engines are fond of when we are running at open throttle.

BOOSTane is designed for all levels of vehicles.  This includes street vehicles that are also untuned.  BOOSTane Premium is going to be the best option to unlock your vehicles full performance.  It allows your vehicles ECU’s natural adaptive capability to add a few degrees of timing, especially if you are in parts of the country that only offer 91 octane.

BOOSTane’s proprietary formula and mixing charts enable easy-to-use tuning.  Our certified octane results allow our customers to tune their vehicles and have the confidence that the ratio that they tuned for will be identical for every use.  

However, the issue with other octane boosters is their ability to reliably achieve the same octane on each fill up, or increase octane at all in some cases, as stated above.

You can see here dyno results of tuning performed with BOOSTane fuel solutions.

Octane is a rating for a fuels ability to prevent pre-detonation, or combusting before being ignited by the spark plug. Fuels achieve octane in various ways, whether through latent heat of evaporation, heavy metals, or refining, all with various pros and cons. Always be sure to understand the fuel that is necessary and sustainable.


BOOSTane Professional and Premium can be blended with E85, and it will give added benefits to the fuel.  – Add stability to ethanol hygroscopic nature – Increase E85 effective octane number While we have experienced the added benefits above, due to the unstable and unreliable nature of E85, especially from the pump, we do have any quantifiable testing performed to give blending ratios, etc, only qualifiable.

Yes,octane boosters, such as BOOSTane can offer the same octane and performance as race fuel, if used properly.

Yes, higher compression engines REQUIRE higher octane in order to run without damage.  learn more

All ofBOOSTane’s productshave a proprietary chelated carrier that not only stabilizes its own formula to maintain suspension, but also has the ancillary benefit of stabilizing the gasoline that it is blended with in order to prevent phase separation from ethanol supplementation.

The higher a fuels octane rating, the more compression and heat that fuel can handle before spontaneously detonating. If you are able to increase compression (more air and more fuel), you will have a bigger explosion within the cylinder, leading to more performance.

The other reason that you may needoctane booster is if you do not have sufficient fuel available at the gas station.  This is very common on the west coast of the US and around the World. If you are in a warm area, and have a higher performing vehicle, there is a good probability that 91 octane is not sufficient to maintaining optimal engine performance and efficiency.  For these cases we recommend ourBOOSTane Premium Formula


Absolutely not!  99% of octane boosters on the market provide little or no octane enhancement whatsoever.  Resulting in no performance increase or even a drop in performance, with a worst-case scenario that your vehicle requires a higher octane and you rely on a poor product, and after not receiving adequate octane, damage the engine.  

If it comes in a plastic bottle, simply put, it doesn’t have enough active ingredients to provide any real enhancement.   While there are products that do increase octane and performance, now you have to be aware of fuel stability and phase separation of active ingredients, seen here https://www.youtube.com/watch?v=l-WmsURxC18

In a comparison of BOOSTane and a competitor that falls our of suspension and causes fouling.

BOOSTane’s proprietary carrier technology and fuel stability enable an industry leading octane delivery and performance.  No reliant on clever marketing tactics, just dyno and octane testing, we are committed to providing the best fuel solution on the market.

A lot of corrosion that happens today to internal engine components, in our experience, comes from the supplementation of ethanol in our fuels (E10, E15, etc).  This is due to its hygroscopic nature (affinity to absorb water into the gasoline). This absorption of water then causes phase separation, gumming up of components such as carburetors, and of course, the drying out and corroding of seals, rings, and other components. BOOSTane’s proprietary carrier actually works to solve these negative side effects of ethanol by stabilizing the fuel to prevent phase separation.  We have also formulated into our solution lubricating chemicals that actually help prolong the life of these various engine components. So you should be good to go! Please let us know if you have any other questions.

It is easier to think of BOOSTane as a race fuel concentrate.  Essentially our engineers figured out how to take the active ingredients in the world’s most popular race fuels, remove the “fillers”, and develop a proprietary carrier that enables all of those varying density, active ingredients to remain suspended indefinitely in solution.  Therefore, when you are blending BOOSTane with your regular pump gas, you are basically adding back in the filler, and effectively transforming your fuel to race fuel.

It is always advisable to utilize AT LEAST the recommended octane that the manufacturer recommends. Many import vehicles and performance domestics are designed to run most efficiently on premium 93 octane fuel. If you are in California or places that cannot provide 93 octane, your vehicle will adapt, but performance and efficiency will be lost.

BOOSTane has been regarded as the worldsbest octane booster by SEMA (Winning Launch Pad Product of the Year) and many other prominent tuners throughout the industry.  This is a direct result of the engineering, development, and constant testing that the BOOSTane team is committed to. Not sacrificing quality for price, and dedication to our customer’s performance.  There is no other product on the market that performs to the level of BOOSTane or provides its certified testing to the public.
