Could someone please tell me if e85 goes very sticky when left for a few days and not driven when you pull off the intake?  |

| There have been some reported cases of this. Two possible reasons can be 1) pipeline drag reducers put in the gasoline portion OR 2) certain gasoline additives not compatible with ethanol. |

I've seen a little of this myself down in my intake plenum. Nothing significant though, a little gummout takes care of it.
I have no idea what it comes from, it doesn't seem to hurt anything.

Have you guys been seeing this on older cars or late model stuff?
Reason I ask is that we have seen some of this as well in needle and seats and other areas but it has been on stuff with older tanks even with pump gas and only the 10 percent ethanol.
The ethanol is acting like a detergent and cleaning all the old deposits from the cars gas tanks and although the fuel filter catches the bigger stuff we have seen some with a sticky residue as well.

| Tech@BG -- have you kept track of where these issues have popped up around the country? |

One thing to keep in mind is that I have NEVER heard of this in an FFV. As an example mine has 214,234 miles on it--all but the first 19,000 miles and a few miles here and there (rare) are ALL on E85. The E85 I run has 0 additives in the gas portion (natural gasoline) and only corrrosion inhibitor in the E98 portion. Original injectors, never out of the car, runs like a top. Same for the Silverado, the Implala's, and our Taurus. Same for my personal S!0-- all high mileage. Several theories exist for why this occurs (but rarely) on these modified cars. Is it the additives in the gasoline portion? Is it pipeline drag reducer? Is it purely related to injector type? Is it related to boost or high compression?
Larry and I have worked on this some for a while. It would be helpful to know ALL of the below- some does NOT help much;
1) where do you get E85--got a phone # for the station?
2) is it always the same place
3) if you put it in a CLEAN glass jar and hold to sunlight or white light-- Is it perfectly water clear OR does it have the slightest yellowish tinge?
4) how many miles driven?
5) how much time since you started using it?
6) brand of injector and any other data you have on it.
Give some background on the engine setup, what was done to clean the tank prior to starting E85 use and after a month or so, What filtration (in microns), what is the tank made of?
I have received some detail from a few guys- thanks. Unfortunately there is so little info or few reports is has proved impossible to conduct the few dots we have.
Right now I do not have interest in carb or intake runner deposit- these just have not caused issues I am aware of. |

Alcohol , I see you followed the link I posted and joined. That e85 section is getting pretty active over there recently.
I am sure you will be a great help to those guys 
turbo buick guys have never been shy to experiment with fuels and i think a lot of them are watching those threads in the e85 section.
you are on a mission to tell the truth about this fuel which is why I am here
take a crack at this one ?  :

No thanks to arguing with BBA on HP Tuners- he is blinded by his gasoline- you guys have handled him pretty well. One point though is that we normally consider E98 to 113 octane and E85 to be 105-109 depending on the hydrocarbon used while E70 is 100-105. One can get in all sorts of arguments as to octane with all alcohols because the octane like effect comes mainly from cooling- not like gas where there is an isoctane connection. You will find info on the web showing E98 ethanol from 94 to 118 octane. That said however- arguments do not run engines- experience shows E85 stands up very well to high octane race fuel knock tolerance. Search this site for some of the old stickies and links. Larry (Hotrod) has done a super job pulling data into one place.
The Buick bunch does seem to be an active and interesting group. I will do what I can- which for me is to deal with questions on the fuel side. I am out of date for pulling wrenches on newer stuff but I do have well over 20 years in the energy business that hopefully I can help them with. This issue though rare with EFI has proven stubborn to get to the bottom of. Once I get full data I will got back to my resources and perhaps they can help- so far the data gathered is too incomplete for them to help with much analysis. What is baffling is that if it is occuring at any of my stations I am totally unaware of it even though I have tried to keep myself available to the growing performance crowd- perhaps it is because I do not use normal gasoline nor any additive other than the standard corrosion inhibitor?
I did get sample highly concentrated additives made specially for E85 but with the way I make E85 it would appear to be a waste of money. Perhaps they would be good for someone like you to test. One is a detergent and one is a lubricant. Problem is they would be hazmat to ship but might be worthwhile- it is used at approx 3 ml per 10 gal for each one. |

Mine is a new repop gas tank and new AN lines. No old parts here. I get my gas at Meijer -- always the same place.
