I was near some E-85 the other day and i have a couple vehicles that sat for a while.I got about 4 gallons of E-85 and added a bottle (qt) of lucas top end treatment and added it too the cars that have sat they didnt have much fuel i would say it was around 50/50 gas and E-85 do you think? did this do anything they dont seem to like it really.But the one car i have had 10 yrs and maybe put 100 miles on it any input??

The cars listed in your signature are not designed to run on that amount of Ethanol. IF you mixed it 50/50 you still have roughly E40. Unless the tanks are now full I would add as much regular non ethanol as you can to further dilute it.
 
i realize that but there are people who run pure E-85 in non flex vehicles just look on the net.I have bought a lot of injection cleaners in the past and like the red bottles of heat i believe the E-85 is similair and i just used it to try to clean the fuel system out.I dont know if it did anything just like the fuel treatments i have spent money on.
 
http://green.autoblog.com/2007/08/07/can-any-car-use-e85/ thats what i thought but it is suppossed to get rid of water and scour the fuel system thats what i wanted to do.But i was thinking about running it in my Regal L67 i will have to research it more i know the ECM would have to be modded or a good tuner that will adjust the fuel tables.looks like they removed the video but there is some info there. http://youtu.be/HuOs1yap8mU

This is just once and blue moon event right? If so I would not worry about how much E-85 you have in your tank now, in the grand scheme of things this should not cause any long term damage. There are a couple of members are running a more concentrated Ethanol mix than you in non-flex fuel vehicles and have for years with no ill effects. That being said I do not recommend that you do this often unless you are willing to pay the consequences.
 
ya i understand that but do you think it cleaned anything? i put the lucas top end cleaner to be safe i used it in the older 2 vehicles and they both ran worse.The old buick i have has a stumble i cant get rid of i was just hoping the E-85 would clean it out.Like i said i let it idle a lot but its only been driven 100 miles in the last 10 yrs.
 
Older GM vehicles used a fuel composition sensor to determine alcohol content.If you dont have one,I dont see how it will run on E85.Plus you need special injectors/fuel pump/rubber to take the added alky content.Chrysler uses green color in its Flex fuel parts.GM??
 
Get it out as quick as you can. These older vehicles were not designed for alcohol fuels, and you may do damage to the fuel system
 
i ran it out best i could and put some premium in it i just wanted to clean it i am hoping it did. there are people running 100% E-85 in regular vehicles.
 
Ethanol doesn't play well with the Bosch and Delphi injectors found in the L36 and L37 engines.
Try Redline SI-1 its a good PEA based cleaner that works really well.

aimsoil has PI cleaner

Yep its good stuff as is Techron. I like the SI-1 because its approved for continuous use at 1oz/10 gal.
I run the whole bottle in a full tank to start then 2oz every fill up thereafter, it keeps thing clean.
 
Reactions to E85 vary greatly based on the car. With the current tune, etc, I ran a tank of about 45% E85 (probably somewhere between E35 and E40). My injectors aren't big enough to run E85 straight, and I'm not sure if the computer will adjust enough based on the O2 sensors before it hits its limits and throws a CEL. However, on the mix, other than getting a bit worse mileage on on E10, it actually ran better

I have no idea why, but it seemed to love it.
 
The Lucas stuff is motor oil with a bit of detergent.
I won't use it again.

Fill it up with normal E10 to dilute the E85.
Use chevron Techron, Berryman B12, or even Seafoam to help clean things.
BTW, you have to drive the car and give it running time to really help.
Sta-Bl will help for long term fuel storage.

I can't see how anyone runs E85 on cars designed for E10 only.
The injectors can't flow the required amount of fuel, and the computer tuning is all wrong.
You need about twice the flow.

Most OBDII cars can add up to 30% extra fuel based on O2 sensor feedback. Provided the injectors are large enough, that's usually good enough to let you run a pretty decent mix (although most can't run straight E85 without bigger injectors and/or tuning).

Yeah, the tune won't be ideal if you're doing that, but provided the fuel system components hold up to the extra ethanol, it'll run.
