Here in MN, with the exsception of a few stations that have REAL gas in their premium blends, we get to run 10% all year. In the toilet? Not me, but it is noticable -- high 40s on gas, 38-42 on blend overall.

How is this good?

What am I missing?
If you get 10%-15% less gas mileage using gas that's only 90% gas then what is the point?

Just Go

Actually I've read that you will experience about 3% loss in gas mileage. Ethanol has 70% of the BTU's that gas has. So if you save 3% cash on 10% ethanol/gasoline you break even.

I've been burning ethanol in my LT for most of my local riding for about a year and the mileage in town has not changed significantly. Sure it's not something else; maybe you should try another supplier.

Could be something els, I will go through the usual trial and error. I will start with the motronic reboot. My current mpg went down from 38-40 mpg to 30-35 mpg .

We have 10% ethanol here in Wisconsin too. According to the BC and my own calculations when I fill the tank, I'm averaging 43-47mpg. It mostly depends on if I have a passenger and/or whether I'm on the expressway or backroads.

My Auto-Ed teacher friend says it's all politics. It is a means for farmers to sell their crop to the Govt, who in turn makes it the consumers problem. It may cost less at the pump, but the gas mileage is worse like you said, and it's only harming engines in the long run. Farmers are happy though.

*disclaimer - I'm just passing the word from my Autos teacher friend. I appreciate farmers and all they do for this country.

10% Ethynol

A 10% reduction in mileage is typical for uses here in Wisconsin with fuel with 10% ethynyl. As was previously noted the effort is largely political to benefit farmers.

With some searching one can find stations that do not sell ethynyl. In Wisconsin the information must be posted on the pump. It does not have to be conspicuious though. Usually, Shell stations have real fuel.

Since no one discounts ethynyl there seems little reason for using stations that sell it.

Thanks Tim, I may try that but here is what I found this AM on my commute to work.
Temp 30, once on RT 80 speed range 75-90 GPS average 85 . Reset mpg gauge and the mpg average was 30 for 20 miles. Once at the office I pulled the motronic fuse. I will reinstall at about 12 noon and retest results to follow tonight.

my understanding is that the federal goverment has mandated that all gasoline used for motor fuel contain 10% ethanol. omurphy

I think most highly air polluted cities require oxygenated (ethanol, methanol, MTBE) gasolines. I think if you get away from those areas, you can find 100% gasoline.

We might have the MTBE fuels in here in Atlanta, but I know I haven't seen Ethanol or Methanol fuels.

Here in Rochester, Mn....I am getting mid 40's on regular oxgynated gas around town, with a little highway. Out on the highway - cruising the 2 lanes, I am close to 50, sometimes higher. Seldom use premium, no pinging etc.
At any rate..... Sure beats my F150, and the LT is more fun to ride. Too bad it is going to be winter soon.

After the motronic reboot my mpg went from30 mpg to 35.4 mpg .Similar riding pace but temps were 20 degree warmer.

I was facinated by this thread, as we dont have ethanol fuel added to petrol here in the UK. I wondered why, so I did a bit of searching;
"about 70 percent more energy is required to produce ethanol than the energy that actually is in ethenol." (basically, it takes fuel to grow the crops that produce ethenol - more than the resulting BTU gained from the ethenol produced)
AH - then why do it in the States?

Ride longer then check it.
I don't think your letting that tractor get warm enough before you plow.
It takes so many miles for the engine to warm up and switch from enriched mixture to standard (which is why all fuel milage is worse in stop and go driving)
Someone can most likly explain it better

Good point Rock, But my ride to the interstate in the am test was 15 miles. The evening test was a 7 mile trip to the highway .The bike was up to operating temperature. It was the same exact road with the exception of first W-E travel in the am 30 degree temps verses
E-W travel in the pm and 50 degree temps. The E-W travel had less hills.

I think it takes 12-20 miles depending on ambient temp.
for the fuel mapping to switch over.
Put your BC on mpg ride on the highway at a steady speed from a cold start. You should see a big jump in mpg when it hits the warm up mark.
I wish I could ever get more than 40mpg.

Well I tell ya Cook1e....Here in the States we grow more than we need then sell and give away corn when we have too much in order to keep the prices up, of course the government comes in and subsidizes when crops aren't the best. By using corn for fuel we can run up the demand for corn there by increasing the price for corn and help the environment at the same time (even though as you state we use more enerygy {ie. pollution} to create it, just don't let the environmentalists know that). Here in the states we call it POLITICS....

but I think it is ethonol or alcohol blends that you do NOT want to mix with the e-85 that is out as well, it is reaking havoc on many motorcycles now causing all kinds of issues with fuel injection and carbed models of bikes, I mean liike dead on the road type issues and costing bucks ro repair

I have seen that crap as far south as N, Carolina off I-85 someplace

Interesting, I run mine up to between 5K and 6K around town and don't get into 5th except on the highway. I never ever get lower than 42, figured not BC mileage. Must be the difference between my '00 and the newer bikes. As a matter of fact, I've don't think I've ever gotten lower than 40 chasing the guys around N GA, NC and TN in first and second gear. I'll check again next weekend during the fall Iron Horse get together.

Steve,

I burned a whole tank in 1st and 2nd working with Susan Galpin on 60 in N. Georgia week end before last and only got 38 MPG on that tank. Normally I get around 42-46 depending on how hard or fast I push it. See you up at Ironhorse.

John, Don't forget there is a difference in gear ratios between my 2000 and your 2005. That could make a difference in the mileage.

Looking forward to seeing you too. You bringing the SO?
