Question about pure gas

[mdandashly]

I've been doing some reading on pure gasoline-pure gas meaning ethanol free. Does anyone have experience with this. From what I can tell it won't hurt?the engine but will help it and increase fuel efficiency.

Interested in trying it for a few tanks and reporting back results but wanted to get the forum's thoughts on it first.

No it won't hurt. That's what it was designed for. If you haven't found it yet, there's an app for it

What's the app. I've been browsing pure-gas.com.

What are your experiences with the gas?

I have done a lot of first-hand driving and comparing the use of E-10 (max 10% Ethanol) as well as E-85 (max 85% Ethanol) and this is what I found:

I was driving about 4000 Mi/month so I had plenty of windshield time to do the comparisons.
Vehicles:
1995 Jeep ZJ (Grand Cherokee) w/ 5.2L V-8
1998 Dodge Grand Caravan w/ 3.3L E-85 compatible V-6

The point of my test was to determine which is more cost-effective: E-10 or plain gasoline, based on the expected lower mileage obtained from fuel with E-10. I expected to follow the same for the e-85 test.

On the Jeep, I filled up with non-ethanol 89 octane and recorded my mileage. I did this for the next two weeks and filled up at the same gas station each time to keep the test consistent.
I then did the next two weeks by filling up at a different gas station that used the 89 octane E-10. For two weeks, again driving the same route, filling up at the same location, I averaged about 2 MPG LESS than the previous two weeks.

The fuel cost was about $0.12/gal less for the E-10 than plain gasoline. Long story short, it was less expensive to run the PLAIN GASOLINE.

My results on the E-85 were even more dramatic. Long story short, the E-85 had to be 33% LESS cost per gallon just to break even. At the time, the E-85 was running about $0.65/gal less than plain gasoline. It had to be $1.00/ gal less in order to break even.

Prior to all of this, I was a heavy Ethanol proponent. Afterward, I agreed with the naysayers about the loss in performance as well as mileage. Since I am not able to test emissions, then maybe there is a significant reduction there, but at what cost?

If I have a choice, I will choose plain gasoline over Ethanol, but there are cost break lines that need to be considered. E-10 was about $0.12/gal break-even on $3.27/gal fuel. The E-85 was $1.00/gal on $3.25/gal fuel.

I thought it was interesting on the E-85 van that it smelled like Everclear when idling instead of the normal burned gasoline smell. makes sense since it's 85% alcohol........

mmmmmmm.....beer.........

I really wanna check it out. Just about finding a station close by maybe a marina. Was just worried about any potential negative effects since I've used e10 exclusively in the past.

Also, add that Ethanol gasoline doesn't burn as clean in your engine.

 

[BILT4ME]

All USA vehicles since 1992 have been E-10 compliant. Only those labeled specifically with E-85 stickers can accept the E-85 fuel. ALL USA made vehicles since 1985 can use plain unleaded gasoline.

I haven't used it in my truck. I just buy it for my lawn equipment... especially the 2-stroke stuff.

The app is for the puregas.org website. It just maps the gas stations closest to you using the GPS on your phone

 

[mdandashly]

I'll run some tests when I can and report back my findings. I currently track my mpg with an app and get a consistent 10/11.8

 

[mdandashly]

Reporting back.

Unfortunately I won't be putting pure gas in. In my area (Miami) it costs $1 more per gallon than regular. I just can't see that paying for itself.

Wow... Has ethanol really been around long enough that "pure gas" sounds new and novel?? Yikes! I can't stand e10. IMHO it's bad (def not good) for our cruisers, it lowers mpg, fouls rubber, absorbs water, etc etc etc. and the politics behind it?? Ok ok... Not going there. I fill up with "pure gas" ie -gas- whenever I find it. There used to be two stations in my little town, both are now strictly e10, hafta go into Bellingham now to get it.

E85 certainly isn't efficient but with the right tune you can get a lot of power with it.

of course our trucks aren't really tunable. And sometimes you need higher volume injectors as well.

There are kids with subaru STIs who drive from 50 miles away to fill up on E85 in my town. Some 30-something guys with bimmers too.

 

[mdandashly]

I'm just not sure I can justify the additional cost. I'd need to at least get close to braking even.

 

[Mr Cimarron]

I boycotted ethanol gas pumps years back. Can't do that anymore now that all pumps local to me have ethanol in them. I now just stick with diesel vehicles but I'm sure they will start messing with that soon as well.

 

[Mrtwooooo]

I think if you can tune a car to run specifically on E-85 and take advantage of the high octane it has then mpg would be better and the cost difference would be less ( I think that would work). On the cruiser that's not possible. Pure gas would be the best for sure.

I have heard when it comes down to it, it actually takes more than a gallon of fuel to make a gallon of ethanol .... figure that one out

 

[Footwork]

I don't know about y'all's 200's, but mine has the no e85 on the gas cap. EDIT: Gah, sorry thought I saw 200 sonewhere in the replies. Carry on 80's

pure-gas.org.... Alaska: All gasoline is ethanol free.

Igf you help me find a job in Alaska I'll move up there and wheel with ya

The evaporative emissions system in the 80 does NOT like blended fuel. It was designed to cope with real gasoline and the blened crap gives it fits. My fuel economy dropped close to 20% when real gas vanished from my area....
