Non ethanol MPG's

[bankrobber]

I filled up with regular non ethanol gas today but it was 50 cents more than E-10 gas. Wondering how many MPG's it will increase. I was getting 38 mpg on ethanol gas and will need to get 44 mpg to break even for the price difference.
Anybody try it before? Also to let folks know I got the non ethanol gas at a self storage/u-Haul dealer in Mt. Dora Florida

When they switched, it seemed to be about a 10% difference in MPG. That was going from non-ethanol to E-10 back when it became mandated... I lost the 10%

Being a newer vehicle, you may not see as much of a difference.

I tried however really didn't get that much of an increase tbh.

[bankrobber]

well that's disappointing to hear. I'll see what I end up with but with such a price difference I wont run it again. I do use it in my small engines and boat though since it can store longer

I don't think that the MPG is the clear reason to buy non-ethanol gas here.
I think in the long run the ethanol can have bad effects on the whole fuel system.
Though the newer cars are being made to withstand that, Some of the older ones are already looking at some pretty costly situations.

I have 169k miles so I don't see ethanol as a big problem for the fuel system. I cant see paying 50 cents a gallon more when I have not had any fuel system issues. Just thought I would try a tank for the mpg difference. I have a boat with an inboard Volvo from 1981. I try to only run non ethanol gas in that old engine

From what I have read in the past ethanol does have a worse mpg by a few percent. That being said ethanol in gas is at most ten percent, so your loss would be (.3) in mpg if the loss is 3 percent for the total that the ethanol replaces. (.3) would not be a show able difference in most driving.

Fuelly calculated my car obtained an average of 42 MPG on the last tank of non-ethanol gasoline.

Has anyone else besides me discovered that his/her Yaris attains much higher fuel mileage than specified in the official documentation? I mean, the fuel mileage is phenomenal.

Edit: Not necessarily related to non-ethanol fuel, but just fuel mileage in general.

Yes. Since my car's 6th 'purchase date anniversary' on October 7th 2012, I've only had 3 tanks under 40 MPG city/hwy combined (I looked this up in my log book a few weeks ago, just out of curiosity). One of those tanks = 39.99 MPG and the other two were well over 39 MPG (and I don't have a ScanGauge or any similar device). I filled up earlier today and my combined city/hwy MPG for that tank was 43.09 MPG.

I have a pretty good feel for how close to empty I can push it. I keep a mental note of the bar drop intervals (for just that tank, not any previous tanks) in my head. I was headed toward a particular gas station today. I came upon the station closest to my desired location (but more expensive). I knew my desired station = pretty close, unsure exactly how close, but knew getting enough gas to go 4 miles would be enough. I already had 548.4 miles on that tank. I grabbed a few coins and got 33 cents worth of gas (0.102 gallons) and then headed toward my desired station (located it on gasbuddy.com a couple of hours before that) -- the gas/convenience store 'pod' at a Kroger grocery store. The station turned out to be 1.5 miles away (and I also did some shopping at that Kroger). I filled 12.658 gallons into the tank at Kroger, so that tank = 549.9 miles / 12.760 gallons = 43.0956113 MPG (and CTScott, on a past thread, calculated the maximum the tank will take is 12.8 gallons)

Well most people dont know but when the vehicles are tested for their MPG they use zero ethanol fuel to test them. So you wont really get much better than the test number because now you are using what they used instead of fuel thast been diluted 10 percent with ethonol. In the long run its better for your car it wont eat through your evap hoses and lines well as pure gas will. So even if the mpg is slight difference if you plan to keep the car for a very long time say 10 years or more i would do it if i had a gas station near my home that supplied zero ethanol. I have seen a lot of flex fuel cars that are designed to run high concentration ethenol having issues already and that is what they are designed to run on.
