Non ethanol gas

I have a 2014 taco with 4.0 has anyone used E0 non ethanol gas in there truck and if so how did your taco run

 

I ran an experiment with E0 over hundreds and hundreds of miles on a trip to New Mexico a couple of years ago.

No significant difference in mileage or runnability over E10. Certainly nothing that could be related to the heat content difference between gasoline and ethanol.

That work reassured me that for day-to-day driving E10 is fine.

I still use E0 in engines that can sit for longer periods, like my lawnmower. The ability to start them and carburetor life definitely seems to be improved there.

 

Thanks, I was interested if the non ethanol would improve mileage, because I do notice a difference in mileage when using a top tier gas as to not. And it was significant.

 

Had a 2013 4.0 OR for a decade. Switched to using only 0E after 4 or 5 years till I traded a few months ago. Never noticed any mpg, or other, difference or had any issues but was buying from almost solely the same station most times anyway.

I did it more for keeping the E out of it, as at times it would sit for a bit and the big temperature swings up here would have me worried a bit about condensation in the tank. If you're driving often enough it's probably not worth it - ours is only in premium of r0E, so more $$

DEFINITELY use it in any small engine apps.

 

Lot of energy in ethanol. If there wasn't dragsters etc wouldn't use it. It isn't worth the price to use high test and the gain is miniscule.

Shoot by the time I use the mower it's has evaporated because if the ethanol!

 

My only antecdotal report is once when I ventured N where there was winter blend gas I dropped MPG and power. E0 did make that better on subsequent refills.

Here in FL E10 is fine. Like @4xdog suggests, I don't use it in anything that sits long periods. Lawn services use E10 fine because they go through lots every day.

 

during our season of blackouts and wildfires, I kept 10 gallons of non-eth around. I ran it in my generators to keep my fridge and some lights up and running. (later our computers and internet...and yes, TV)

one year, the event was a non-event so I had 10 gallons stored. I don't store fuel, so I poured it into my 2006. mentally, it ran awesome. hahah. but yea, no real benefits I could tell. expensive tho. at the time, $6 per gallon, maybe.

next time, I'll dump it into my friends bass boat. I am not supposed to run it on the highway.

 

I run ethanol free gas in my 1980 20r because E10 didn't exist when the motor was built. I have no idea if it helps or if I truly need to do this. But for some reason I swear that little 4 banger likes the E0 better.

 

I dump around 4 gallons of non ethonol from the boat tanks into the Taco at the end of fishing season every year. Might just be my imagination (i'm old, confused, and have a bad memory lol) but the truck seems to run a bit smoother. As far as gas milage goes i wouldn't know... never checked it and don't plan on starting.

 

I have always seen better gas mileage with E0 vs E10, but it's not enough to justify the cost difference. I still use E0 because there is a vendor in the area here that has E0 mid grade, so the cost difference is less, and ... E0 (but I won't go any deeper than that ).

Ethanol will not make as much power as gasoline, gallon for gallon. Ethanol dragsters can make more power because you can inject more fuel into the cylinder without detonation, mostly because ethanol creates a higher cooling effect during vaporization.

 

Ethanol has about 30% lower energy content than E0 gasoline for equivalent volume. Alcohol-fueled dragsters use methanol mostly (uncommonly ethanol), often in a combination with nitromethane. I always understood that to be for the greater resistance to detonation of the alcohol fuels.

Interestingly, methanol has even lower energy density than ethanol (ethanol: 5.4 kWh/L pure liquid v methanol: 4.0 kWh/L pure liquid). Gasoline has 8.9 kWh/L, and diesel is the highest of all at about 10 kWh/L.

 

I don't normally chart mileage for my 2015 DC OR, but for my long western camping trips. The typical mileage profile is lower on the westbound leg (often to San Diego) and higher coming eastward homebound. I've always attributed that to prevailing winds.

Here are some typical profiles over the last few years using E10 for the whole trip. One will often note a slight increase in average mileage by the time I'm back east. And the difference tank-to-tank can be quite high depending on the driving conditions (weather, winds, speeds, off- or on-road...)



Here's the data where I made a point to use E0 ethanol-free "pure gas" for a thousand miles or so. Note the green bar across the bottom of the chart for E10 and the blue bar for E0 to show what fuel was being used at that point on the graph. E0 was on the mostly homebound leg, so one would expect a slight increase in mileage. I judged the difference between E10 and E0 to not be significant.

 

That's an unexpected result (unless your engine tends to form deposits in the fuel system that the TOP TIER™ detergents help clear out). Do you have any data from your experience you can share? Does the mileage benefit last for a while when you go back to a non-Top Tier fuel?

 

Mathematically running higher Oct fuel is not more cost effective. This horse has been beaten, slice it anyway you want.

Rough examples.

On average the price difference between 87 and 91 is .50$

87 @3$/gal 16mpg cmp: .1875

In order to break even at 91 you would need to average 19mpg.
Cost savings nets you 3/10 of a cent. Cpm:0.1842

On average e free cost a dollar more per gallon. Do the math.


I run 91 occasionally because it makes me feel better and I like to think it helps clean the fuel system. I do not run 91 and expect it to be a financial gain.

 

It's all I use because it's easy to get in my region.

The thing to remember about the pump is that the verbiage is "may contain UP to 10% ethanol". The percentage is not always exact so the calculations and comparisons are all over the place as a result.

 

My experience is limited. I won't pay the price difference locally. But on a road trip a few years ago I found gas dirt cheap in Mississippi. Non-ethanol was still much more expensive, but about the same price I'd been paying for E10 everywhere else so I tried a tank. That tank got the worst fuel mileage of the trip (5000 miles). And performance was noticeably worse.

My guess is that the station where I bought it sells very little of it and that gas was probably old.
