What additive are you using for upper engine/cylinder and fuel system treatment?

Probably going to be making the switch soon just curious as to if anyone has a favorite or a preferred brand and for what reason. I was thinking of using Lucas Safeguard Ethanol Fuel Conditioner, i've always liked Lucas products. But if you've got something else let me know.

 

none, but i only ran e85 for around 30k miles.
check the Exodus website , i forgot what it was recommended
for additives

 

whats with you and that site haha

 

its more informative than here.
I dont go much there any more because
i haz no cobalt nor I am near my HHR


this is like nasioc to rs25 is to the other site ^_^

 

Check Gm sc

 

I've ran e85 for a couple years and never used any additives and would store my car over the winter months, of course my tank would be less than a quarter tank. I would just start it once every couple of weeks just to make sure the fuel flows through the lines and not just sit there. If an additive is recommended I'd like to know about it.

 

there is absolutely nothing on cobaltexodus lol. idk what you're smokin.

well the people who are recommending it are the ones selling it. so i'm just trying to see what people have to say who have been running it.

 

nothing on ^this exodus website?

hmm i guess ask there ^_^

 

for real. what have you been smokin hahah. that's gmsc. cobaltexodus has been dead since the day it started. there's nothing there but boomer and his thoughts.

 

Ben off and on e85 for a few years now. Never used any of that crap. I would look into wat gm recomends cuz theres no difference in our fuel system and a car that is labled flexfuel. All gm fuel systems for the past 10+ years r ethanol tolerant. And even some cobalts come ready to be flex fuel just need the ethanol sensor in the tank to activate that part of the tune. I know the LE5 pcm and the newer L61 pcm r setup.

 

ex.... my 2 cents is an additive is pretty un needed..... the only thing i can recommend is a tester bottle to test your e85 concentration. the gas cities(speed way) and all those other junk gas stations are readily available here but they all need to be tested because of inconsistencies in the gas. ALL of our cars we tune for e47 e85 etc etc we run shells e85 and have had great sucess.

the only other thing is make sure your fuel system is ready for it which im sure you know.... pumps, lines(should all be teflon), filters, injectors, seals etc etc.

 

No additives used here, granted i've only been on the corn for a couple thousand miles.

 

Like everyone else said, no need for any additives unless you're storing the car and want to preserve the fuel. I run E85 in summer and 91 oct in winter so I like to think the gas in winter "cleans" any gunk that built up from using E85 in summer. I also have a 2010 which has upgraded fuel seals that can deal with ethanol. Not sure if you need to worry about the fuel system if you're running a blend like E47...

 

so general consensus says no additives

yeah i'm definitely going to get a tester, no sense in risking anything. i don't think there's any shell stations around there but i've always had good experiences as far as their 93 goes. but this rs fuels place that i'll be going to it seems everyone who uses e85 for horsepower goes here and they've never had any problems.

what all would you recommend changing in the fuel system? i was going to see if theres any orings for the injectors that are ethanol safe. i'm for sure getting rid of the aeromotive pump though, i've heard too many people(not just cobalts) have them fail on ethanol. but since i maxed the fuel system on 110 i'm more than likely just going to go with 190s and dual pumps to replace the 80s and stealth 340. i've already got the brfps and rewire to go with it. i'll get a filter for sure, but what about the lines are they not ethanol friendly oem? i haven't heard of anyone really doing anything when they switch to ethanol so i'm not sure.

 

theres a lot of pumps out that can take the abuse of ethonal..... all orings, seals should be replaced with ethonal grade stuff, lines should ALL be teflon(you CAN run the stock stuff for a bit but it will fail eventually so i recommend a change), check out our site and we have a 700hp pump kit

 

i guess i'm not finding it.. i hope 700 is enough though lol.

what lines would you recommend?

 

i personally like aeroquips stuff or russel is second best to me..... anything with a teflon inner lining should be good.

ill pm you

 

alright sweet. thanks man

 

I personally use this treatment Safeguard™ Ethanol Fuel Conditioner with Stabilizers : Lucas Oil - Safeguard™ Ethanol Fuel Conditioner with Stabilizers, but that's primarily because I store my fuel in a 55gal drum. The closest e85 station to me is over an hour away so when I buy it in relatively large quantities I ere on the safe side and treat it for when I stock up. Sometimes (especially in the winter) one drum will last me a few months at a time with how little I drive the car. Ethanol breaks down relatively quickly so for me it just makes sense to treat it. In the vast majority of cases, you're totally fine without treating it.

 

that's the same stuff i was thinking of using as well. i've always had good things to say about lucas products.

 

What about using seafoam or is that no good for e85

 

None needed soccer. If you do use some for long term storage the lucas stuff is perfect. Just use twice the recommended amount. My local mower, small engine repair shop, did tests and proved that product recommendations don't take care of enough water absorbtion.

 

Seafoam is rated for ethanol.
