just goto the fuel testers website they sell the kits. I am thinking about just buying a drum and skimming the ethanol out. From what I hear its not hard, just time consuming. If I can ever stop being lazy enough lol.

10% Ethanol is mandatory in NYC. cuz we have the biggest a-hole mayor. all the **** he did just ***** NYC more and more everyday. funny thing is, some morons I know who vote for him now regret his decision, no **** moron, hate to say I told u so.

same thing for NJ, and PA, so nope, nothing for me

You keep coming up with ideas, and when do I get to ride in your Cessna?

I took lessons in a 150 once long ago.

Ok, just lay the 55gal barrel on the side with the 1" bung with a valve at the bottom and 2/3 full of E10.

Run a water hose with about 10 gallons on that, and swish side to side, and let settle over night.

Open pet **** at bottom, and pour water out which will have lots of ethanol in it.

You will know when the gas comes because you can smell.

Then, everything in the drum is gasoline with way less ethanol than before.

Put isopropyl (rubing alcohol) in to clean up any leftover water, and I think you'll have at E05 or less.

Yeah I have seen a couple of methods, but you can seafoam the fuel instead of rubbing alcohol it. We only fly when we go back and forth to the ranch, but you missed out on the good flights which are during Xmas to go see all the lights!

why didn't you finish your license?

dont forget you will lose a little octane when you take the ethanol out!

I got up to soloing out of the Austin airport with a Cessna 150 in Feb 1973.

Last day I was out I was practicing power on stalls; it recovers really quick, but of course you gotta be up to 3k ft to make sure.

So when I try to land, keep getting cross winds at the last 100-200ft, and with the money I know will be expended to get proficient and buy a plane, I quit while I'm ahead.

In March of 1973, I see a working model of the Mazda rotary at some UT Expo, and go buy a 73 RX3 asap before Nixon devalued the $ 10%.

It cost $2995, and was my second best love affair; my RX8 is the best!

REDRX3RX8

Docbeech,

So do you have a Cessna or a Beech?

One thing that I couldn't get past was the radio.

My hearings not the best, and I'm half crippled, but I just couldn't make out what the tower said.

I can barely hit the pedals for HPDE.

So what airport from DFW, Addison?

KHQZ actually. My dad and I fly Cessna aircraft. The Beech thing is just a coincidence. God I would to be a part of the family :P. No luck there though, Spent most of my time flying 152 Aerobat. We be poor folks who can't afford the good stuff.

One gallon of xylene for every 9 gallons of ethanol reprocessed E10 gasoline will produce 91 octane.

REDRX3RX8

I here ya. I got ride with someone who came out to Pecos with a Cessna Skyhawk (150?).

Anyway, he was gonna show how good it performed on a 110deg day at 2700ft airport altitude.

Now I like to test it too, but power stalls at 3k ft above the ground, not on takeoff.

The plane is barely fliable at that altitude air density, and he's trying for altitude on takeoff.

The local crop dusting company, Lukins, had a son that took up some kids, was horsing around with low level power stalls to scare them, and accomplished a real good scare with a straight nose in.

Also, two different ranchers went up, put it on cruise, known to drink and fly, and disappeared.

I grew up with a healthy fear of machinery after watching lots of nonsense.

Oh, another guy who was a local freight guy with a new license, took off in fog, made a 2-3 mile arc in the sky, and went in at a left bank.

We both can see the basic errors made, but planes need real respect.

DocBeech

Or you need the right plane, the 152 is modified to be a performance flier, the 150 is more for just two people to enjoy flying. Uncoordinated power stalls are the best kind btw.

Just a quick datapoint for the discussion:

A typical target lambda for a forced-induction Renesis is .78. This translates to about 11.5 AFR for gasoline and 7.1 for ethanol.
That means that the target AFR in open loop will be almost a half point richer for E10 than straight gasoline. (9*11.5+7.1/10).
Though a half point isn't a lot in theory, when you take into account the different effective AKI of E0 and E10, you are giving up a huge margin against detonation.
Even though ethanol has an actual AKI of 122, its stoichiometric ratio is only 61% that of gasoline. So, in injected quantities equal to gasoline (since the PCM doesn't know any better), its effective AKI is only about 74!
So, an E10 blended to 91 AKI (RON+MON/2) only has the actual AKI of regular gasoline (even though you are paying for premium)!

So, when you are tuning for 11.5:1 on 91 octane and you switch to E10, you are now effectively "detuned" for 12:1 on 87 octane.

Zoom. Zoom. Boom.

This is why I shoot for high 10's on local fuel.

Yet another data point:

I just received my ethanol test kit from the EAA.
I tested two samples:Sample number 1 produced a result of 3% ethanol. The pump it came from is NOT marked with any sort of "oxygenate" warning, as would be expected from "race fuel", which this is obviously not. I do not expect, nor would I pay $7 a gallon for, "race fuel" that contains ethanol.

Sample number 2 produced a result of 13% ethanol.

I am not pleased.

Had the gasoline in the tank not been diluted by almost 1/3, it might have produced a result as high as 15%!!!

I will get gas from a number of different stations around here and see who has the least - and the most - ethanol.

Wow. Where did you get that test kit? I found several places online but they look kind of shady to purchase from.

MazdaManiac

Uh, click the link in the post?

I checked the gas at the local "top-tier" station - Quick Trip.
There are quite a few people here in Phoenix (myself included) that swear by this gasoline brand and it certainly seems to have lived up to expectations so far in that it doesn't knock when other well-known brands would.
The test sample produced result of ~7% or so ethanol.

Is there any way that we can sue them for having more than what its posted ?

probably not worth the trouble and 15% is coming to rape us all soon (actual % is higher and we all know it )

I love how Obama make it sound like "renewable" energy thing is such a wonderful thing ...

I know Corn-based Ethanol is not the only renewable energy but come on ~ that alone waste so much money that could be use for something else thats "WAY more" useful.

Scary stuff in regards to the wild swings in ethanol content. Honestly Jeff I think much of the differences result in people not knowing the difference. I'm very surprised with ethanol in race fuel. It makes me wonder how the hell it got in there in the first place if it is added at the station and not prior to being transported.

nycgps

iTrader: (1)

Its probably "premix" before transported.

Cuz one of the best thing about Ethanol is it raises the Octane rating ---- cheaply

MazdaManiac

iTrader: (3)

It is, actually.
Of course, ethanol isn't technically "renewable" energy since the well-to-wheel is high and the resource itself is very limited.

It is a pretty big regulation violation. I think simply bringing it to the attention of the consumer protection groups and the station management would be enough to scare them straight.
It is likely that it isn't an intentional over-mix. Rather, it is the result of settling.
Of course, the Republicans want to do away with regulation, so such complaints will eventually fall on deaf ears.

15% is not certified for models older than 2007, so it will only be offered at specially marked pumps.
Remember - ethanol blending is not a money-maker for station owners.

Probably not.

Can't be done.

Not really.

olddragger

iTrader: (3)

totally agree with you MM and I am sadly not surprised by your finding. We got much the same results in Ga as you did. Even from some Top Tier stations.
This knowledge was one of the reasons I choose to install a water meth kit. At least i can bump up the octane a little. I am probably hurting the engines peak performance capability, but dont care.
This is a big thing for tuners. Obviously.
