Just read a post where it said if you have a half tank of Eth gas you can fill it up with non eth.Said it cuts the Eth in half.Is this true??
Don’t know the math in it,but you would still have the same amount of ethanol in the tank! If it sitsfor a whileyou will still get phase seperation which is the bad part!
Best advice is NOT to mix!!

In terms of just math, if you have 20 gallons of the ethanol blend (10% ethanol) and you top off with 20g of non-ethanol, then you did cut your ethanol percentage in half (you’re down to 5%).
However I cannot say anything about the wisdom of this, I do not know if 10% ethanol-content gas is basically just normal gas with just 10% ethanol in it. I’d suggest looking into adding fuel stabilizer to it if you do this— but make sure you are getting the right kind.
I have avoided E gas since 4 Summers ago when it cost me $500 to have 3 carbs rebuilt. The little more I pay for non-E gas is worth it.

By doubling the amount of gas in the tank with ethanol-free gas you are effectively cutting the percentage of ethanol in half. I have mixed non-ethanol with ethanol (using Sta-Bil ethanol treatment, and only when necessary) with no adverse effects for several years. I believe the secret is to not let your boat sit too long between uses, which is exactly what I tell my wife!
I have seen this debated on many different forums and here is my 2 cents. I feel it is fine to add non-E gas to E-gas at anytime. The reason I believe this is that the ethanol is not added to the gas until it is loaded on the truck being transported to the pump. So how is it ok for the gas suppliers to add ethanol to non-E gas but you can’t reverse it the process? All you are doing is diluting the ethanol that you already have in the tank. Now I don’t use E-gas due to the problems if caused me in my yammie 150 4 strokes. If you chose to make sure you run a decarber and startron.

Due to an illness in the family the boat sat up for only about 3 weeks. I’ll avoid ethanol for as long as possible. This was E10 not the now approved E15. I now add Startron with ethanol treatment to every tankful, just in case. I’ve had no problems since going back to straight gas a year and a half ago. Also, my boat mechanic says to avoid ethanol if at all possible.
When this tank is almost empty i will change filters and fill up with non Ethanol gas.Towing the boat is a pain for me.I use non ethanol for all my yard stuff.

I can get a 125 gallon tank for the bed of my truck. I am sure we could coordinate a fuel run. Just get close at limehouse and pump her full.

The do not mix rule is from when gas had MTBE. When the gas with MTBE was mixed with Ethanol it sludged up. MTBE has been banned for a while now so it’s safe to mix. That said, I would run the tank dry to get rid of all ethanol gas in the system and make a permanent switch to E-Free

if you read the gas pump you will notice it says “may contain UP TO 10% ethanol”, so it could already have 5%, or more, or less. i would encourage mixing with non-ethanol as to minimize the ethanol in the tank.
10% is not a magic number that makes your engine run better. the less in there, the better.
hey steelytom; one thing for sure; you difinitely know how to run a tank dry. ha ha ha ha
I was a boat repair and sales marine and the subject came up about ethanol . He said a customer of a new boat purchased from him had bad engine problems and after looking into it , the use of ethanol was the problem . The man said he never used ethanol gas in the new boat . The marine shop picked up a gas test kit and it showed he had 30% in his gas tank .
I don’t think we know what we are getting when we buy gas .
I test my gas before each fill up. It is not hard to test for alcohol in gasoline. All you need is an olive jar, some duct tape and a few ounces of very clean water. Mark the olive jar about two inches up from the bottom with the duct tape. Fill with clean water just up to the duct tape, make sure it just tuches the bottom edge of the tape (tape is on the outside of the jar). Now fill the jar with the gas in question and shake it hard for a few minutes. If the water level drops there is alcohol in the gas, no drop means pure gas. The color of the gas in question can also provide an indicator, a pale green color MAY indicate e-gas. Also we need to “hitch up our drawers” for e-15. All car maker are voiding wanranties if this trash is used in thier cars, all makers except GM that is. Wonder why. (Government Motors?) Please watch the attached video and call you congressman.

what additives are they using in place of MTBE when they are not using ethanol?

wouldnt the water level INCREASE if there is alcohol in the fuel?
alcohol releases bond with gasoline and grabs on to water.
solution falls from gasoline increasing the water level
we have test kits we sell
there is a blue drop that disolves in alcohol, but not gasoline
then you can add a measured amount of water to the little tube, then a measured amount of fuel.
shake for a few seconds
the amount of increase in the water will tell you the percentage of alcohol
so, where are you getting non-E fuel?

I looked at the Yamaha website, did a search for ethanol and this is what I found there:
But back to Ethanol (E-10) versus non-ethanol fuel. Not everyone has the option of running non-ethanol fuel. In a lot of areas the only place you can find non-ethanol fuel is at marinas, so the person that trailers their boat is more likely to get their gas at a station that sells Ethanol (E-10) fuel.
If thats your situation, a good option is to buy the Yamaha Fuel Stabilizer and Conditioner Plus to add to your fuel tank. This product helps prevent fuel oxidation and phase separation problems associated with Ethanol (E-10) based fuels while preventing many of the corrosive properties. Adding Yamaha Fuel Stabilizer and Conditioner Plus to your fuel will allow you to store your boat or not use it for up to a year, without the fuel gumming up or forming varnish normally associated with fuel that has sat for long periods of time.
At the same time, adding Yamaha Ring Free Plus to your fuel system will help keep the internal parts of your engine clean. The Ring Free Plus cleans the internal parts of the fuel system and eliminates carbon build-up while protecting them from future damage.
Lastly, one of the most important components of your fuel system should be the water separator, which filters out the impurities like water or the debris and corrosion that gets loosened in the system by Ethanol (E-10) fuels. Yamaha recommends using a 10 micron water separating fuel filter with Ethanol (E-10) based fuels.
I thought that I have read where the new engines (2013), ethanol can be run while it is better to use non-ethanol fuel, it is not detrimental using regular gasoline. BUT is is important to change the moisture separator and to use the additives and gas treatments.
