E-85 Cure With Fuel Additives

What are we looking for in an oil going full E on our platform?

So far, the best oils I've found are ones certified to work well with E85, like the Dexxos oils (here in the states).

I don't actually recommend that you do this, because in order to produce the sticky, you may need to heat the fuel to flashpoint (which guarantees a fire).

I was testing to see if a ceramic coating could shed the sticky, but learned something more valuable instead.

Oil does relate to this post, as I am testing SI-1 on full E85 with Penrite oil....

But yes it is going a bit off topic.

[MSP6]

S1 used to rebuild pump only-3rd tank, 500+ miles, no pressure dips or issues yet.

[MSP6]

Car just sat for 2+ days at 40 degrees or so. 700ish miles total, zero issues at start up.

Forgot to update thread; local test car is back on the road with a new tune hes apparently in love with. He's also going to swap over to RP Dexxos oil soonish and see how long that lasts; I've already set his expectation that we will probably have to pull and build his pump again at some point though.

[Enki]

New update! Test car smokes like a burning coal mine. Troubleshooting to follow.

In a few more days I'll cross 1k miles and will probably pull the pump and re-clean/lube/make sweet love to it just for peace of mind. I work every other weekend and the office is empty and locked so I can use the workbench there to do it. I don't mind pulling and cleaning it once a month as long as its not on my free time.

Lol apparently; could just be the turbo though, since he's running a used baby K right now and has gone through a few others already.

So that additive doesn't work in 40 and colder weather in Chicago. Running 70/30 (85/93). Was using kendell oil the whole time then just switched to brad penn yesterday and spill valve took a shit..... Pulling pump to see if sticky of Black Death.

Has probably no more than 700 miles with that additive. Car does sit a lot tho. I don't daily it and doesn't see rain/snow/salt.

MYbe not additive, but oil I use..... But idk. Just sharing facts

You rebuilt the pump and everything with the additive? Or just ran in the tank or put some in the top of the pump?

[Enki]

So apparently its smoking less and less, and he found some oil on the manifold/turbo flange area. No idea what's up with that, but will be checking in on Saturday. Also compression seemed within a range of 20 on all cylinders, so there's that.

[MSP6]

Hmmm...
@Enki; tester's car may have issues..
@mazdafreak;s pump has issues @ 700 miles...

mine has none at near 1k...

scientific deduction...

I haz the sexiest pump.

Rebuilt? I cleaned it all out and then Added it to the internals just like littleloogy did



I have always had a problem in cold weather with e85 no matter what. The cold just sucks and sticks the spill valve.

Gonna take it apart soon.





I'm not the tester car...... Just someone who runs E and not trying to clean pump all the time lol..... My car does sit a lot. If that factors in or not.

I know, that's why I separated the two lines. Your car, as well as the testers car. No real point or logic to my post. Just announcing the sexiness of my exactly similar pump....

Also, FWIW I didnt just clean my internals alone. I hit the internals, spill valve and entire pump insides with S-1 goodness.

How much did u put in spill valve? When I did that, my pressure was 60psi till shit started flowing. Or that normal till fuel starts circulating through the pump?

[littleloogy]

I generally crank over for 3 seconds (holding down clutch and throttle). After the time elapses I let go of the throttle and I get a good clean high pressure start. If I cold start without doing this... It stumbles briefly.

Yeah that's exactly what mine did. So either way it's normal till gas starts flowing again.

@littleloogy; how much did u put in the spill valve?

[mazdafreak]

Pump/internals were spot less..... Just the spill valve took a shit.






Pump is clean, not one sign of Black Death

[Enki]

But sticky death everywhere, right?

I put the spill valve itself in a cup of s-1, submerged the entire internal assembly and then pour s-1 into all accessible areas of the hpfp. I also exercised the internals a bunch of times while submerged. All done after initial cleaning. If it was possible for fluid to get there, there's s-1 there. As to how much in the spill valve housing, no idea i didn't measure. Halfway filled it or so.

I also cranked it over for a few seconds on initial startup but haven't since.

[mazdafreak]

No..... Housing was clean and lubed still by the s-1 shit so it wasn't sticky.


The spill valve was a lil sticky tho. Idk if I had s-1 in the spill valve.

[Enki]

Swap to the RP Dexxos oil and see if you can last longer.

Edit:
When you put the pump back on, remove the spill valve and fill the pump up to the first thread, then put the spill valve back on. Should last longer.

I just changed oil and I'm running brad penn oil for added zinc etc for my built motor. It's legit green oil lol.... Okay, I'll fill the spill valve up right now before starting.

[MSP6]

Just hit the 1k mark last night. At 1,040 or so now. No issues. You can faintly see my 999 mile mark in the potato pic.











Only reason I can think of for the success is this...

[MSP6]

Still going strong on original pump rebuild with S1 at 1,200+ miles on the RP. Was gonna pull the pump today and clean and redo it for peace of mind but meh, too lazy. Ordered JBR 3in WP from FS section instead. ($150!?) Also plan on gutting the TP either today or tomorrow so full E85 rape should be realized shortly. Enough of this SRI only garbage.

[MSP6]

Got under the car to nator p'tator my TP, took one look at the state of the spring bolts and nuts and rolled back out from under that bitch. Gonna buy an ebay tp soon-ish. That being said, got this in the mail and installed today. Should see what the corn' s all about now that my hackjob sri is gone.






Also, at 1,400 miles on original pump rebuild. Still chuggin. @Enki; Any updates on your tester?

[Enki]

No smoking or anything; only issue is his car drinks like it's Irish (heavy on the wallet).

[ASHMS3]

Question, did anyone ever try RP without the additive? If not, I might be down to give it a shot after my next oil change.

Using bad grammar from my cell phone.

[littleloogy]

@ASHMS3;
Yup... Gave me sticky death. Not enough to immobilize me but to cause flow problems.

Sent From a Galaxy, Far Far Away...

[Enki]

Same. By far the longest I've been on the sauce issue free though, so I've got rather high expectations for RP+Redline.

[Dano]

hey if you guys don't mind, I would like to take a slight detour here and ask a question...since all the E85/CDFP experts are present.

I recently started dropping fuel pressure and getting the associated sputtering. This occurs with higher load values and/or when approaching 3.5-4K RPMs, light load. It is accompanied with a chatter/chirp sound that is either coming from the CDFP or the RV. Pressure will actually reach zero then bounce back to 1500-1700ish then back down.

I used to run a 4/8 mix of E but recently (4 tank fulls now) switched to a 5/7 mix. I don't recall the sticky death issue being recorded at this concentration. I happen to have two HP CDFPs so today I switched out the spill valve to no avail.

My question is, does this sound more like the CDFP internals or the RV giving out? I do have a 2150 that I can swap in to rule out the 4K light load sound/sputter ( but at high loads fuel cut ensues) and am leaning toward the RV since I don't recall sticky death occurring with E concentrations below 50% and not sure the SV can drop pressure to below ITFP. I can also swap out the entire CDFP.

thoughts?

[MSP6]

IIRC @Enki; or someone said that the worst death they had seen was on a pump from a cx-7 that had never seen E.

When my RV went I had low 300's (psi) at idle and could build it with slow gradual increases in throttle but if I punched it pressure would fall on its face.

If you have an Oreilly near you get a bottle of Redline S-1 and fill your SV up with it. Restart and let it run for a little bit then try again. If its death somewhere in the hpfp the s-1 should clean it up at least temporarily.

[Dano]

hum...I have no problem building pressure at light loads and below 3.5K.

edit: with gradual pedal so maybe the same as you.

[MSP6]

Hmmm RPM goes backwards in a couple lines....isn't that a blowout thing?

WTF.... 0psi 6 psi.. would the itfp cutting cause this? I was under the impression, as you were that when sv and hpfp failures occur you always get the 60psi of itfp.

Its more or less what mine did when my RV was failing...you have a V3 so maybe the speed of it is simply catching those low pressures whereas my old v2 was not at the time.
@phate; @Enki; @littleloogy;

[Dano]

nvrmnd...nothing to see here...move along...lol

this is my fucking little fuel pressure sending unit harness issue rearing its ugly head again.

fawk!!!!

LSS if I unplug the harness and plug it back in everything is back to gold Jerry. This is a 2 YO issue and happens when the weather turns cooler...anyway I need to figure this out once and for all. I guess the FP sensor is talking gibberish to the ECU and the ECU is working the piss out of the SV which leads to the chirping noise.

sorry for the derail.

[MSP6]

No worries, I was gonna say it seemed electrical with those readings because 0psi should result in way more than a stutter I would think, but then you having the V3 threw me off because its supposedly so much faster. Glad you got it sorted.

[Dano]

yeah the 0 psi from the sending unit is what was freaking out the ECU so it cuts fuel via the SV...same as an over psi reading which a 2150 RV will give you ...lol

I have spread out the female pin receivers in that harness, but dielectric grease in there...I need to find and injector harness and replace the entire thing I guess. The sending unit has already been replaced as a troubleshooting step.

lol the saga started back in 10 of 2011
