Big power FI turbo tuner told me - 5 days in the tank and it's junk. Screws the tune up. You want to save it, drain it back into an air tight drum. Otherwise it's weed killer.

If the results don't match the theory, change the theory.

I would test it for what percentage it actually is I started off dnyo testing with E75 and ended up using gas from the same pump that the dyno shop bought three weeks later and I used it a year later, it that had set in plastic race jugs in their dyno room for that year. That fuel tested out to be E90 and ran good I'm having a missing issue now with my race car now with old fuel, maybe I should drain it and try a new batch to see if that is it It tests now to between E87 to E89 in three different jugs

I had 15-gallons in the vented tank since Aug 2016 (9 to 10 Months) I have the test tube type tester that tells alcohol percentage, but not sure how to tell how much water it had absorbed?
I may be having some other issue wit the carb, but right now I am thinking the old fuel?
The problem is the engine won't idle right, and when I punch the throttle the engines seems to go lean? Once the RPMs come up it seems to run fairly good. This is in comparison to last year. No changes were made, and last year it would blow the tires off, now it wants to fall on its face?
Have you taken the carb apart? Sitting that long the fuel in the carb will absorb water. That water in the bowls will cause corrosion. that maybe plugged some of the bleed passages or even is obstructing the jets partially? When my carb is going to sit for a while I drain it and spray wd40 to protect the insides. Also when e85 sits in plastic jugs for a long time the gas component (15%) will evaporate as noted by cab and others on here. Your tune maybe off if it was close to being lean before. More ethanol % needs bigger jets. It's not as corrosive as methanol but it will attack bare aluminum over time, especially if there is water involved! Don

AH, Love the smell of REAL GAS in the morning..........no where near worth the hassles........... What hassles? Before I switched I heard all the horror stories. "Sucks water out of the air"..."destroys fuel system"..."corrodes everything"..."Inconsistent ethanol content and will make the car run different each tank". After four years I don't have a single complaint. Car runs cooler, makes more power, less swing with weather changes, and has totally paid for itself vs. $9 a gallon for junk 110.

All in how you store it. We have seen the corn liquor percentage go up when stored over long periods in plastic drums or jugs a couple times. We don't really have any issue with water absorption as we have no humidity here, but could see that as a potential issue for sure. When we first started with it we would see it "jell" in the carb if it sat for long periods of time, like when doing bodywork and paint.

Won't run better since e85 carb is 30% richer. Eyes will be watering

I run straight alcohol and it isn't without its issues. It stores very nicely in 54 gallon plastic jugs. I just bought to drums of it last night for 165.00 each so I'm set for awhile. Last year prices took a nice dip down to 135.00 a drum during the Summer for some reason. I drain the carb and dump transmission fluid down the carb while it is running and shut her down for Winter storage but I till have to freshen the carb every Spring. Most of the guys that ran E85 at Keystone switched over to alcohol.

I will take the carb off this weekend and check it out. I like the idea of using E-85, but I don't run the car that often anymore, so I will either have to drain the fuel between useage or switch back to race gas? Being that cars have a vent on the fuel tank and E-85 will separate( the alky is still there but will reduce.. the open vent system will absorb in the water so it ends up as trash over time) .. it should be stored in ONE type of container the has the barrier in the container.. it can be either a metal drum or plastic.. but it HAS to have the the barrier.. production fuel tanks have it and good fuel drums or fuel jugs/cans.. if you were to cut a production fuel tank in half you can see it easy(I've cut open a few hundred of them).. if it sits in the car for a period of time(more than a week or two you will see the slime starting.. and it gets worse over time.. I forgot to drain my carb over the winter one year.. it didnt look good and it was a 1/4" thick and started to corrode my 1050 carb a fair amount.. drain it and run some decent fuel through the whole system to wash out the E-85.. other than the water issue its great stuff and CHEAP race fuel

You guys a lucky! Only station that sells e-85 has been testing 50! 55gal. Barrel e-98 here is 275.00. might go back to race gas! Side note, it's been killing my o-rings in my Pump changed them over to Viton after the first time it leaked. What else could a guy use?
