E10 and MPG loss - Land Rovers Only

DiscoSE03 · 03-25-2008, 10:20 AM

Anyone using gas that has 10% ethanol? Here in PA almost ever gas station exclusively sells e10 (gas stations usually advertise they they sell e10, but they are not required by law to inform the consumer/display that their gas is e10) and i have noticed that my MPG has dropped to 12-13MGP since this has occurred. my truck is stock, i drive conservatively, and it is regularly maintained. When the gas is e10, does that mean i have to use 93 octane because 10% of the gas i am buying is ethanol? or is 91 octane still alright (i get better MPG with 93, but it costs 20 cents per gallon more)? Does the use of e10 have any negative consequences other than the loss in power and MPG?

Thanks

why would you run ethanol??

If you read the stickers on all pumps in all states, I believe, they are all using 10% ethanol, and yes it will cost you in mileage.
Your D2 should be run on the highest octane, here in Colorado, I can still get 18MPG at 65 MPH on the road.

He isn't running it by choice, some states require gas stations to have E10 or gasohol to reduce emissions, unfortunetly it makes most cars get worst gas mileage. A few years ago they were adding MTBE to oxygenate gas but it was screwing up a lot of cars O2 sensors and making them impossible to start so now they are forcing gas stations to carry E10. Here you can read more about at the below link.

Be careful, E10 is not as bad as E85 but the discovery is not flex-fuel. hard on the motor and flex-fuels don't have as much energy content.

What's the point on having gas that supposedly reduces emissions, when it just takes you more gas to get where you're going ???? Sounds like if it ain't the same at the end, if one thing it's probably worse.

That's the government (EPA) for you, they love to implement programs before they are even proven to work (see MTBE). Its all about politicians voting on something that sounds good at the time.

I wasnt going to get into it, but apparently the switch to E10 and in some places E20 (colorado and minnesota by 2013) is part of Bush's attempt to curb harmful emissions. Only problem, at least as of now, is that to produce and use a gallon of ethanol you end up creating more emissions than you do with a gallon of regular gas. This is a result of clear cutting forests to grow crops to make ethanol, which reduces the amount of carbon dioxide that is being absorbed by those trees, the fuel (usually diesel) that is used to produce and than transport the crops to refineries and then to gas stations, and the loss of power that a driver experiences when using ethanol that causes them to buy more gas. Its also contributing, in part, to the rise in the price of food.
Im not sure why the Bush administration pushed so hard for ethanol and why Congress accepted it.
