Use the boat and gas, You will have no issues. Let it sit idle and I'll grab :popcorn: too.

I like Sta-bil marine. No product will cure ethanol, but a stabilizer is the best thing to protect against the hygroscopic property of ethanol.
Startron is also good stuff.

Also, depending on the age of your motor, it's not a bad idea to replace the fuel lines with the new fuel lines that are ethanol-resistant.

I'm Blessed that there are a couple of gas stations here in Lubbock where I can still buy ethanol free gas!

Stabil is a preservative that acts as a sacrificial molecule to prevent oxidation the same way BHT acts in foodstuffs by oxidizing before the gasoline begines to oxidize. It doesnt do squat to ethanol. Mercury's position that a 10% ethanol blend helps to keep water out of the fuel system by absorbing it and helping it pass through the system is valid.

A search at pure gas . org , and you might find that there is/are stations near you that sells non ethanol fuel for use in you motor along with other lawn equipment that sets for periods of length. Otherwise most brand name fuel stabilizers should be fine for storage of 6 to12 months. Topping the tank before storage helps reduce the amount of condensation in metal tanks, but really dose not help with plastic tanks. JMO

I used Stabil, then switched to Phase Guard 4, when West was out of Stabil. Used it in the gas for all of my small engines and OB. No problems, even with 1 YO gas.

Re: Ethano lfuel treatment??

No product can do much to prevent the real issues with Ethanol, although many claim to be a cure-all. Nothing will prevent phase separation except more ethanol, which isn't a good idea. In actual testing Sea Foam did very well at preventing corrosion on metal in the fuel system, other "miracle in a can" products did little, or the cost was very high for they did do.

The potential issues with E-10 are hyped to almost unbelievable levels by marketing departments in an attempt to scare into buying their products. After 20+ years of using E-10 or some various blend, I do nothing special with my fuel and have no issues, which is normal for most people. There are some specific situations where more care needs to be taken in how the fuel is stored, large capacity tanks in boats moored for long periods of time and such, but for most boats discussed on iboats E-10 isn't much of an issue.

I use Star-Tron.... it eliminated issues with ethanol and preserves your fuel for 2 years. Be cautious where you buy it, it's not all the same. WalMart and Advance Auto sells it but it's $9 for 8 oz that you need 1 oz per 3 gallons. The stuff that I buy takes 1 oz to 16 gallons!

Re: Ethano lfuel treatment??

I would love to find a product that eliminated fuel issues, but nothing has been proven to do so in independent studies. Even though the manufacturers or marketers of the products claim these things they have fallen short every time. Some can and do help in some ways, but Phase separation is where they all fall short.


" ASTM D130
04e1 Standard Test Method for Corrosiveness to Copper from Petroleum
Products by Copper Strip Test: Ethanol Shield is rated 1A, the highest level of protection possible."

In my current eight outboard motors (from 3.3 to 200HP), some I’ve owned since new in the late 60’s, none have had any corrosion in the carbs, even when left for 10 years unused in the corner they would start right up, some did need a quick cleaning of the low speed jets to run perfect though. These motors were never meant to run E-10, but have for more two decades with no issues.

"ASTM D525
05 Standard Test Method for Oxidation Stability of Gasoline (Induction Period Method): After testing, which simulates 1 year of aging, there were no signs of fuel aging with Ethanol Shield added to the gasoline, up to 1-year stabilization. Ethanol Shield stabilizes up to 3 years when used according to instructions."

How does this compare with similar products on the market, again in independent studies?




"ASTM E1064
08 Standard Test Method for Water in Organic Liquids by Coulometric
Karl Fischer Titration: Ethanol Shield has the ability to draw up to 3.9% mass of water in a hydrocarbon solution. This is an excellent level of performance considering that E-10 gasoline only holds up to .5% of water in suspension before phase separation begins."

So this product absorbs more water than ethanol before phase separation?

I have run E-10 or various blends for more than 20 years now and I’m still waiting for the horrendous issues that claim to be “normal” for it. I do nothing special, just fill it and go, this is the same for virtually every boater I know, and very few of us have had issues. And few of us even give it much thought until we go online and read that we are supposed to be having major problems with every component in the motor.

Yes I do know there are situations where E-10, and even E-0 have problems in long term storage, so products that can deliver on the claims you make would be very useful.
I’m not saying your product doesn’t work, only that none have proven to do so yet.

I didn't see where this product was TCW3 certified, or even recommended for an outboard. I'm not saying it needs the cert to work, only that "oil" is not "oil" when it comes to outboards.

We just started making 2 cycle with anti ethanol additive in it from the factory, pm me if you want to give it a try.

It appears this stuff is for air cooled 2 strokes. Are you recommending this for use in water cooled 2 stroke?

If it causes problems, is your next recommendation this stuff? product link removed

Don't you know it's cruel and inhumane to cram a Mechanic In a Bottle.

EDIT - I shouldn't leave links to salesmen
