NO ETHANOL 91oct
« on: August 05, 2017, 08:52:42 pm »
I'm in the dirt bike capitol of Colorado and we have two local distributors of NO ETHANOL 91oct at the pump.
Shell is the one distributor for both locations.
The pump placard says "NO ETHANOL ADDED" and is only available in 91oct.

At $2.939, it's worth driving the C14 17 miles just to fill up with this fuel.
It runs well, I think much better than the "10% ethanol added", for this altitude.
At 9000', I'm 48-54mpg with this fuel and I ride enthusiastically.
The bike runs very well and quite responsive up to 12000' with this fuel.

If you ever see this available, it's worth running a tank or two with some BG 44K.
Ethanol is a killer of your fuel system if not treated for winter storage.

I use pure gas every chance I can get it. Both of my bikes seem to like it.  We have 87 regular pure gas which the 900 uses. I have to go out of town and up a twisty road to get pure gas for the C14. Darn it.

I find this useful when planning trips:   https://www.pure-gas.org/

Go to the Pure Gas website pure-gas.org to find a list of stations state-by-state with no ethanol premium.  There is also a Pure Gas app for iPhones so you can carry the list with you on trips.   :motonoises:

you guys are fortunate to have those options.

I have 1 place 15 miles away selling RV gas but they get a almost double the $ more for it than the alcohol lace stuff.

with several bikes it isn't practical time or $ wise.  (as if owning several bikes at once is!)

next closest ls an hour and a half away.

I would think that at altitude the octane-reducing qualities of alcohol would be a benefit. With less oxygen available in a given volume of air, a vehicle will need to lean out the fuel curve (why carb engines have such trouble at altitude) to match the oxy content. Isn't higher octane about reducing detonation at higher combustion pressures of high-compression-ratio engines, and at altitude those pressures are reduced by the lower atmospherice pressures?


Hopefully one of the resident gurus (Steve, Rev!) will chime in and correct my misunderstanding!

I found my 4 stroke bike ran better on 89 regular out there in
the mountains. I am told it evaporates better. I had been running
your premium and it was missing a lot till I switched to regular.
I guess that's why you sell an 87 also.

JDSCO, Are you coming to Montrose, Co to fill up? Sounds like it. My C-14 and my KTM both like it. I do add some Marvel's Mystery Oil and a dash of fuel injector cleaner when fueling my Concours with the no alc fuel. I can really tell the difference.

Montrose is two hours from here. My fuel points are 17 miles or so from my house.
Headed to Ridgeway via Montrose next week. Is the Black Canyon Gang still together?
C14 and a KTM are a great combo, for sure.
My KTM is a 990Adv. I ride it everywhere off road and I always fill up up with No Ethanol 91 when I can.
That twin runs very well at 12,000' and 91oct. 30,000 miles of running well.
We're fortunate to have never had problems with altitude/octane.

I just went through Monarch Pass from East to West and then back through a few days later West to East on my 10 day trip to Cali from Oklahoma and back. I might be back in September just to tool around Colorado for a few days. Love it up there.

I have the pure gas app and pretty much stopped using it as it is woefully inaccurate around here.  In IL almost everything is is 10%.  In WI almost always, premium is alcohol free in the towns we ride.  Buy it whenever I can.

In Western Washington some Cenex branded stops have No Ethanol Premium. I will go out of my way to get it.

I completely understand your apprehension to make that post.  If I were smart enough to make that post, I'd feel the same.....now with that said....I have one option that I'm aware of to buy non ethanol fuel.  It's a new convenience store at Derby, IN.  That location only has one option for non ethanol fuel and it happens to be premium for some reason.  Derby is right on the river and has a boat ramp, so my guess would be that boats and personal watercraft like higher octane?  Derby is on route 66 and has lots of Harley traffic.  Do Harley's like premium?  If it's not that then maybe they're just looking to justify the big difference in price compared to the cheap stuff.  The only thing I own that requires premium is the GTP.  I will admit to not running premium unless it's crazy hot outside with no repercussions, that I'm aware of anyway.  It has plenty of giddyup on the cheap stuff and makes no extra unwanted noises.  Soo when I go through Derby, I fill the C10 up with premium just to get "real" gas.  Are you still awake Steve?   :D :D  You know what happens when I get started!   :))

I guess I'm missing the post that you're regretting.  Are you forgetting something? :nananana: :nananana: :D :D  If it's plain as day and I'm just not getting it.....don't hesitate to splain it to me. :)) :))

Being the op, I'm joking around
but I'm not changing my fuel preference
I have no other No Ethanol octane choice
I've read the COG octane threads containing Steve's knowledge/input. His science is solid. I get it!
I've tried Colorado 87 octane ethanol fuel in both C14's. My 2008 had 40k Colorado miles
For me, neither C14 ran "better" or worse and I had to deal with stabilizer additives
That additive throws the affordability factor into more expensive. Right? Stabilizers aren't fuel performance enhancers
I have a KTM 990 Adv with 30K miles and it's very reliable with good power at 12000' on No Ethanol 91
I know Colorado ethanol fuel is not the same quality as one might find in Houston or Orlando
This is because of our average 5000' alltitude and most people can't tell the difference
I've probably been buying lower octane than labeled ethanol fuel for years
I know that as long as I have the choice of No Ethanol 91oct vs any ethanol fuel, I'll stay with No Ethanol 91, every time
They just run better, also

Station near my house sells no ethanol in all three grades 87, 89, 93. I go with the 93 in all my street bikes and my dirt bike. I don't have to use the 93 in my 600 race bike because it is dyno tuned with two maps, one with a no ethanol 87 and one map on VP MR12 fuel. I can use the 93 in the race bike since the tuner split the difference on the timing numbers between 87 and 93 at the time the bike was tuned. It just doesn't make the HP numbers on pump gas verses the MR12. :)

DOH! :-[ :-[  Wasn't paying attention to who the OP was.  Sure would be nice if there were more non ethanol choices in octane and stations.

You guys don't know lucky you are. Here in Kalifornia it is almost unheard of to get real(no alcohol) gas. The two exceptions are race fuel $$$ and boat gas, but they will not sell you boat gas unless you can prove you have a boat.
And yes I spelled Kalifornia that way intentionally. If you don't watch carefully you get E15.

MOVE!!!  ;D




The marine gas is likely not taxed as on-road fuel Is my guess.  But I wouldn't be surprised if they did, anyway.

Steve,

What is the threshold to switch back to 91?
I live at around 5400 feet and have access to an endless supply of 89 E0 fuel.  >:D
It would be interesting to see if I can get over 60 MPG.

I lived at 6500', regularly drove up to 10500. Couldn't tell the difference between 87 and 91 octane. Got my best economy going into Silverthorne- 11 miles of downhill :))

  I can't say for sure but at your altitude air pressure is decreased by about 18%... that's probably enough to safely reduce octane a couple points. Steve
