About Ethanol gasoline.

This is a tricky answer. E 15 is a higher ethanol gasoline mixture and seeing as ethanol is semi corrosive it is highly dependent on your car. Most cars manufactured after 2007 are in the clear but there is no certain answer unless the manufacturer gives the green light. I have attached a great article detailing e-15 but I would recommend calling your local dealership, and asking them if your model is e-15 ready.
Is E15 Going to Harm Your Engine

The government mandated 10% ethanol in all gasoline fuel sold for automobiles, so You have to use ethanol blended fuel just about everywhere. That blend is suppose to go up to 15% shortly.

Are you sure of the ratio? Here in the states E-85 means 85% Ethanol and 15% gasoline.
If that is the case, and your mix is 95% Ethanol You will have hard start when cold, less power and the check engine light will stay on. I have been running E-85 on my gasoline vehicles here for the last 5 years. I have had no other problems.

When the light is on you need to pull the OBD codes with a code reader or go to an autopart store and have them do it. With that in mind ethanol changes the exhaust coming out of the engine, the ethanol causes the oxygen to be higher in the exhaust than is expected and the light comes on. You should have the codes checked to be sure. However there is no damage coming from this light, if that is the cause.

The standard 10% ethanol will not cause any harm. Do NOT use E-85 or any more than 15% or you may have problems.

Note: 85 Flex fuel is 85% Ethanol and if you dilute it with 75% gasoline you get somewhere around 21% ethanol. That is a little higher than I would go, but it may not hurt anything. MPG will suffer as you increase the ethanol percentage.

Ethanol less energy than gasoline. So your fuel mileage will be less. Also if your engine wasn't engineered to run on you could damage the engine.

No A lot of gas stations have 10% ethanol.

Hello Joshdhorz,

The best fuel you can use on your vehicle is any octane that contains at max 10% ethanol.

Ethanol is an alcohol-based fuel additive made by fermenting and distilling crops that have been broken down into simple sugars.

A 10% blend of ethanol and gasoline will not harm any engine or fuel system component. However, the ethanol has a cleaning effect that will remove rust and other junk from the fuel system. This necessitates frequent fuel filter changes until the fuel system is cleaned out.

Most gas stations in our area are set like so:

87 octane (Up to 10% ethanol)
89 octane (Up to 5% ethanol)
91 octane (No ethanol)

Now we do not have 93 or 95 octane available to us here, so I am currently unsure as to what is in 95 octane fuels. In my opinion, I would use 91 octane (No ethanol) for the majority, while adding 87 or 89 octane (5-10% ethanol) ever so often to clean the lines.

I hope this helps you out,

Shadow

Also if you would not mind taking a moment out of your day and rating my solution it would be greatly appreciated. Thanks in advance!

A gasoline/ethanol mixture containing 85% ethanol and 15% gasoline. The number after the E is the percent of the mixture that is ethanol. So E10 is 10% ethanol and 90% gasoline. Ethanol, of course, is the type of alcohol in beer and fun drinks. Jeff
