Ethanol-free gas

Negative.

Workman checks his mileage with every fillup, and tries to only use NON ethanol gas, 91oct which he can purchase at his local gas station.

When Workman could not find non ethanol gas, he got from 17-19mpg. Using non ethanol gas, Workman gets 21-23.5MPG. Thus 3-5MPG more.

Workman loves the MPG he gets on his Taco using non ethanol fuel.

 

I only use it on my small engines. Motorcycles, lawn mower, weed eater, pressure washer, etc.

 

Uh - OK

 

I've used both, pure gas and 10% Blend, and the key to getting better MPG with Ethanol blended fuel is buying from a station the sells a lot of gas so their supply is fresh. The longer anything with alcohol sits the more moisture it draws to it.

I try and use pure gas as often as I can in my 2013 TRD Supercharger equipped dbl cab but I've actually got my best over the road fuel mileage, 22.7MPG, with Chevron 10% Ethanol Super Unleaded.

More important than which fuel you use, with regard to fuel economy, is keeping the RPM under 2000. If you can keep it at a constant 65mph you should get 20-22 pretty easy and if you can handle only driving 60 for the duration of a freeway trip I'm sure I could get 22-24. The hard part isn't deciding which fuel to burn, it's the painfully slow driving one must endure if you want to get into the 20's for MPG...

 

Perhaps, but I can't take anyone seriously when they want to refer to themselves exclusively in the third person.

I wouldn't consider his results typical.

 

If there is 10% ethanol in the fuel and if the ethanol had no energy value at all the best case would be 2MPG if you got 20 MPG normally. You would be lucky to gain .5 MPG Ever wonder why they run alcohol in race cars? If you are using a super charger or turbo you are better off with some ethanol in the blend.

 

Yeah well, would you believe that in the greater Houston area there's not ONE damned ethanol-free service station? WTF?????

 

The way I figure, if I pay ~10% more for ethanol-free gas, and get 10%+ better fuel economy, then its worth it. The added power is the icing on top.
Also, my lawn mower and string trimmer greatly prefer the ethanol-free stuff FWIW.

 

Seat-of-the-pants fuel testing is a waste of time. There is too much variation in the chemical makeup of pump gasoline to provide statistically significant results. Even with identical fuel (no such thing outside the lab, even at the same fuel station) there is too much variation in driving conditions to provide statistically significant results.

A study with sufficiently rigorous scientific methods showed (with 95% accuracy) that gasoline containing 10% ethanol (E10) reduced fuel economy by 3.68 ± 0.44 %, or 3.24-4.12%. Using 20 MPG as the baseline on 100% gasoline, the expected fuel economy on E10 would be 19.176-19.352 MPG.

Unsurprisingly, this is just about what the BTUs per gallon of fuel would lead you to believe.

The difference between the theoretical calculation and actual performance can probably be explained by the fact that we have fixed-compression-ratio engines that cannot be adjusted to wring the best performance from ethanol blends, which can be used safely at higher compression ratios (for better efficiency) than pure gasoline.

Calculating miles per dollar is a simple task. As a general rule, at $3.50/gallon for pure gasoline, E10 would have to be about $0.13 less, or $3.37/gallon to reach the same miles/dollar cost.

When I lived in Arizona both 100% gasoline and E10 were widely available. The miles/dollar ratio was not always in favor of pure gasoline. Here in NH, there is virtually zero pure gasoline available for motor vehicles, and precious little for boats, so there is no opportunity to decide in favor of either.

Thanks, Workman only wants to provide the TW community with the information he has gathered from 6 years of Taco ownership. Workman does not think it should matter if he responds in 1st or 3rd person as long as the info is helpful and relevant to the OP's thread.

If Workman's posts are too hard for you to read, comprehend, or believe then put him on your ignore list or dont read the post. Nobody is forcing you to read/respond to anything on the interweb, it is your own choice to do so. Workman does not talk in third person in real life FYI.

Back on topic, Workman has done many real life experiments using ethanol based fuel and non ethanol based fuel in different makes of cars and trucks. Gas that contains ethanol ALWAYS yields lower MPG.

Workman also does not switch from one to the other expecting the gains to show immediately. If you are running fuel with ethanol in it, empty the tank almost completely, and fill up with non ethanol fuel, you might not see the benefits immediately on that first tank. Workman believes the computer on your truck/car has to adjust to the changes in fuel which could take a tank. Though in every occasion a gain in MPG will be noticed, big or small.

If you run non ethanol fuel in your Tacoma tank after tank, you WILL see your MPG go up, maybe up to 4-5mpg more. 2 other Taco owners Workman knows have tried this experiment and have noticed the same gains as Workman.

Workman goes out of his way on trips out of town to buy fuel from stations that sell straight gas in order to keep his Taco happy and to save money on road trips. PUREGAS.ORG is a great way to locate these stations and map out a road trip. In Workman's case, the difference is as substantial as getting 320 miles to a tank to 400+ to a tank. Workman got 436 miles out of 19.2gallons once, and can always get 400 miles per tank when consistently using straight gas. No bouncing back and forth between straight gas and ethanol gas is KEY.

Hate all you want, Workman is only providing real world experience using straight gas. 21-23.5MPG constantly for a 4.0 4x4 auto pickup is pretty kick ass IWO. Workman's average though the years in 22MPG, and he has only seen 17-19 when he is forced to use ethanol gas.

Oh, and Workman only uses 91 oct.

 

Ethanol is bull shit! Those stupid corn farmers have us by the balls!

 

I call it Corn Grease, and I avoid putting it in any car that I love. Luckily, living in Oklahoma allows me to choose which variety to put in my car.

I see about a 5 mpg difference in my Mazda 3 hatchback. I haven't done enough testing in my new (to me) Tacoma.

 

B11 didn't know these Tacoma's were equipped with a "Self Learning" ECU/ECM.

B11 hasn't noticed much difference in MPG between using pure gas and ethanol blended premium but when B11 can't get pure gas B11 tries to always buy ethanol blended fuel at a high volume station. B11 likes his gas to be "fresh". See, I can do it too...

Anybody remember the "Jimmy" Seinfeld episode??? Watch Jimmy run! Watch Jimmy jump! LOL

 

Lame, so-cal has none......

 

Incorrect

The farmers are only taking advantage of an opportunity provided by the federal government.

 

Florida is moving to repeal the state law requiring ethanol fuel.

 

it sucks.. I rather have reg base gas with 89 octane.. runs better and burns less. I use this more offen in winter due to "winter grade gas". I also use fuel treatment to keep the engine clean during the winter.

 

there is a reason why Florida is trying to make this happen and California is not...but we are not allowed to have that conversation on this forum.

 

Won't happen.
