another black goo thread

[enriquez2000]

I have some injectors ive ran in my honda for a year now on e85 and they were pulled out clean as day... after a couple months in the dsm i pulled them out and they had a slight black drip out of the injectors.. Not like ive seen on the net. Wondering why changing into my dsm would make any difference. People say its additives but one car does it one does not.. same injectors.

This leads me to believe there is something the e85 is pulling out of the car.. now keep in mind my honda is a 95 and talon is a 93.. both used gas until I got hold of them and both have stock line from tank to filter(-6an after fuel lab filters).. What could possibly be the difference?

its possible the ethanol dissolved some "goo" in your fuel system......actually very likely.

 

[enriquez2000]

Yes but both cars are about same age and miles.. why dsm and not honda if its goo in lines?

It's common belief that this occurs from stations switching to winter blends, vice versa. Try switching E85 staions. Worst comes to worse, run a dual map and switch to 93 octane, just a few gallons or soak the tips in gasoline for a few hours. This is a non-issue until it actually becomes an issue.

I started a thread about this not long ago. See here: http://www.dsmtuners.com/threads/wh...jectors-look-like-this.462614/#post-153254961 BTW I've been running E85 on the same lines since then but have switched to FIC injectors. Runs great.

Its just weird.. same injectors and same station yields 2 different results. I plan on 3 gallons of 93 just for good measure here soon. I may just run e50 for winter anyway

Well it's almost winter already, they may have switched blends.

"Our continuing research on the subject has shown that the E85 issue(s) are not only confined to 2- cycle equipment, but also include 4-cycle engines. We are now hearing from passenger car customers, specifically owners/operators of older “vintage” or “legacy” vehicles that are encountering similar gumming and/or deposit issues. As a matter of fact, the issue is compounded when used oil is left in the crankcase during lengthy cold ambient temperature storage conditions. Our BRAD PENN® Penn-Grade 1® High Performance Engine Oils should not be considered for use with E85 fuel. Prior to the very latest PCMO ILSAC GF-5 / API SN (Resource Conserving) classification, most motor oils were not specifically designed to handle E85 fuels. "

And yes I know a BUNCH of us use Brad Penn in our e85 vehicles including my other car on e85 with no issue, but when the company themselves issues a warning.....

Switch to AMSOIL or better yet, run Rotella T6 syntehtic oil. Both have properties that help with oil dilution from Ethanol. I personally run Rotella as it is thicker and has great protection for our engines. It is proven with Mitsu, Subaru, Toyota, etc and personal friends of mine all run Rotella in their E85 powered cars.

They have it right on the fact that injectors will get gunked up while in storage for a long period of time however how much of that has to do with oil left in the crankcase, I'm not so sure.

Hmm that is interesting as I'm about to switch to e85 and Brad Penn oil is all I use.

Talk to the owner of gas station about the blend, they may lie but one I worked for never even switched to e70 winter blend, performance based station. E100(E98) on pump as well year round
