0% ethanol fuel give better mpgs in a V6?

Anyone notice better mpgs in their V6 running 0% ethanol fuel(clear gas) or are the new trucks made for 10% ethanol only?

 

Yes , 0 ethanol is better

 

I pay the extra .15 a gallon for it. Its much better and more responsive along with better mpg's on the highway for sure.

 

wish I had a local ethanol free station here..

 

This

 

I use the pure gas (E-0) and average about a 10% increase in mpg with it over E-10. I make sure it is a TOP TIER Detergent Gasoline brand.

My only problem is I have to haul the gas into my location. I drive around 85 miles one way to pick it up and bring it back about once a month. I run it in all my vehicles as well as boat, and yard tools.

 

According to my really quick search, ethanol has about 2/3 the chemical energy of gasoline. So if you fill up with 10% ethanol mix, your tank contains 96.7% of the energy it would have if you had filled it with straight gas. That percentage should translate directly to mpg. So you're giving up between 3 and 4 percent of your mpg when buying ethanol mix, and if the pure gas costs more than that, you're losing money.

Around here the 10% stuff is going for about $2.60 per gallon. So if pure gas is more than $2.70, it's not worth it, from a pure cost perspective anyway. I have no idea what the long term effects of ethanol are.

 

Wow if the E-0 is only a dime more where you are it is well worth the price. Here it is around 30 to 50 cents more per gallon and I still feel it is worth the price in the long run.

As to effects, on my boat I had special gas line installed that was suppose to handle E-10 and it still wept through with the E-10 over a years time. That and the increased MPG on my vehicles is what made me make the change.
Here are some issues with E-10 and above.

Yes and I keep a can around for the yard equipment. Freakin' ethanol gums up the carbs on lawnmowers in pretty short order.

 

yeah here in CA we have no choice but E10.

 

This^ ethanol will not hurt any thing they are designed to burn it.

 

Ethanol is a solvent it can't gum things up.

Ethanol won't hurt engines designed to burn it, but there are plenty of small engines that are not.

Ethanol absorbs water and is corrosive to aluminum. BMW has had problems with motorcycle fuel pumps and fuel injectors clogged with oxides of aluminum particles.

 

My V6 gets 2.5 - 3.5 mpg better on ethanol free when I can find it and much better throttle response and power.

 

I like it if it's worth it price-wise. I luckily have a no ethanol station 2 blocks from my house. But lately it hasn't come down in price like the other stations.

 

While you are technically correct, ethanol is simply an alcohol, you are creating a straw man- what we are talking about it the ethanol "enhanced" or blended fuels which are not pure ethanol since they contain mostly gasoline. Ethanol is hygroscopic meaning it binds with water and in short it does lead to gumming of small motors that are vented and tend to sit for extended periods of time such as lawn mowers and boat motors. It's not nearly as big of a deal for modern vehicles with closed systems.

Also you might want to tell these guys that since they apparently didn't get the newsletter. Just some of the examples out there including the National Marine Manufacturers Association, Briggs & Stratton and Yamaha.

Here's what Briggs & Stratton have to say about it:

E10 is like 3.2 beer (if you're old enough to know what that is). It looks like beer, it smells like beer, it kinda tastes like beer, but it's just not as potent!

 

I agree. Additionally: Ethanol has less energy content than petroleum. However, it has a higher octane which will accommodate a higher compression ratio. If our engines were more optimized for ethanol (E10), then they would achieve more HP than they do as built for both E10 and E0. I had a Ranger with a Flex Fuel engine and my plan was to install a Supercharger and change the pulley for more boost for use with E85. However, E85 was never available in my area and then I bought a new Non-Flex Fuel truck. The dream died. Haha!

 

Glad to see the appropriate use of "hygroscopic". I remember my plastics classes back in college and people would argue about the hygro vs. hydro.

Although I can't speak to the Tacoma V6 because I don't have the depth of data (15 tanks of gas), but I know my Honda sounds and feels better on the whole with the E0 gasoline. There is no statistically significant difference between the data populations of E10 gasoline I've put through there and the E0 over 45k miles of tracked fill-ups (70 tanks of E0 and 90 tanks of E10). The variance in the populations from "normal driving condition variation" beats out the expected difference of 3% that you would think coming from the energy density math. I see trends but I cannot stand up and say so with any decent level of confidence.

Before the supercharger, there was a noticeable difference between 87 and 92 octane for me on the Tacoma. Perhaps associated with the engine knock? I never hooked up the OBDII reader to see what the knock count was (if there was any).
