You probably know that e-10 gas in everywhere in the US and that is contains 10% ethanol,thus the e-10 designation. Unlike e85 which is to never be used in a car not designed as a flex fuel vehicle, our cars are able to run on e10.
In some states, e10 in mandatory but it does have some negatives

1-e10 is more prone to water absorption
2-e10 provides less power per gallon thus fuel mileage is affected

There may be other affects that you are aware of.

In some states (GA being one of them) you can find limited access to ethanol free fuel. For the first time since owning my 2010, I filled the tank with 90 octane ethanol free gas to test mileage and power over the next few weeks/tanks. Unfortunately, the highest octane at the station i could reasonably get to was 90. The downside to this fuel is the .10 premium in price per gallon but I am curious enough to spend an extra 10 bucks or so for a few tanks.
Its still cheap by some standards as i paid 4.05 a gallon here near my hometown.
Check out the app "pure gas" if you are interested-I am not affiliated with it But stumbled upon it when researching. I'll provide an update for those interested

 

I can't get ethanol free gas anywhere near me. I did see some off-brand gas stations selling 87 and perhaps 89 octane that's ethanol free within a half hour...but that's it.

 

My tank was off brand so to speak (valero)

 

Valero was once an 'off brand', but now is a very large national company. It ranks #12 on Fortune 500's list. I think it is based in San Antonio. The word 'Valero' comes from the original name for the Alamo.

I also seem to recall that Valero is the largest petroleum company that does not do any drilling.

Having said all that, I have not used Valero gas in my Maxima yet.

PalmettoFellow - 89 octane works beautifully in all generations of Maximas. 89 is very close to the 91 recommended for our 7th gens. I have used 89 octane exclusively after the first 18 months in all seven Maximas I have owned, and never was able to measure any change in performance. Of course MPG is not directly connected to octane, so MPG is the same for 89, 91, 93, etc, octanes. But I would NEVER put 87 octane in this car; I feel that is just too far for the fuel system to EFFICIENTLY adjust.

 

I haul gas for a living, we had a looong thread on this subject i started

I searched your posts and found details around "off brand" gas but nothing surrounding using Non Ethanol gas like I did with my most recent tank. Any details on that? Have you tried it before and found the results?

 

Its actually better cause the ethanol is really good as people think. Before the epa came in, everyone didnt use it and cars actually got better gas mileage. I wish we all would drop that damn ethanol crap.

I run non-ethanol 90 octane regularly that I get from a local farm supply outlet. I switched from Shell mid-grade. My experience has been about a 2 mpg gain while paying about $0.15/gal more than Shell. More importantly for me is that it has increased my driving range about 120 miles. That allows me to commute for an entire week (about 360 miles of freeway per week) and still have a comfortable 125 miles range left on Friday night to putt around town on the weekend.

As to power ... I can't say. I seldom, if ever, go WOT. The car seems to like it. I've had no issues running the non-ethanol fuel.

Live long, and prosper

Excellent-thank you for the information. This is what I hope to acheive as well although I will also watch for power since I do tend to use WOT

 

Go to Pure-Gas.org and click on your state and it will give you all the stations that offer ethanol free gas in your state.

 

Around here, there is no E-10. The pumps display a logo that says "Contains up to 10% ethanol by volume" and there's a handful of ethanol free stations around, but the price of that gas is quite a bit higher.

 

I hate the ethanol gas but might as well get used to it cause its certainly not going anywhere. I did have the pleasure of putting pure non ethanol 93 in my car and it was a night and day difference in my MPG. Drove 80 miles and the needle moved roughly half the distance it would with 10% ethanol gas(didn't bother to calculate but I noticed a difference).

 

I guess im spoiled, I got 93 octane ethanol free today for $3.79/gallon

 

I ran ethanol free in my last Maxima and saw about a 2mpg gain. At the time, it was only 10 cents more than E-10 across the street. Used some BiLo bucks at the pump and ended up getting it for $2.99 a gallon for 93 octane E-free. Still working off the free tank of gas from the dealership but we'll see how it goes once I get her broken in.
