Makes you wonder cause you see people with index 1 injectors and so on with no problems that just bought car but anyone making power for most part had to do their injectors. Maybe e85 is what's killing them and they aren't as bad as we think
Yes. At least that's what I read from the various papers that have been posted on this thread.

Yikes very good point I know pi helps keep valves clean but does any make it's way into valvetrain and I wonder if pi increases fuel dilution. I would think most pi guys run very short oci with top quality oils which prob helps tho.The other thing that came to mind was would it be worth it to go DI only to limit the exposure of the valvetrain to ethanol vs using port injection. Haven't heard of ethanol destroying anyones head but i also think people don't thoroughly investigate things when they break.
http://www.marcnelsonoil.com/water-hazards-with-e-10.htmlThe biggest problem with ethanol for an alternative is with "phase separation." That's what happens when the fuel is saturated beyond it's capacity to hold water in solution. Water and gasoline actually separate, and the gasoline floats on top of the water...With E10, ethanol blends more easily with any water. When phase separation occurs in E10, the ethanol is pulled out of the gas and absorbed by water. This results in two solutions, neither of which is good for the engine or fuel system...not to mention the environment. The gasoline left behind is absent of oxygenate. The water left behind now contains a high concentration of ethanol; this solution is highly corrosive and damages any material it may come in contact with in the fuel system. The only solution for phase-separated fuel is to dispose of the entire fuel load, clean the tank, and start over with a fresh tank of E10.
E10's ability to absorb water has yet another drawback; it can absorb water directly from the atmosphere through the vent while simply sitting in the tank. In just 100 days at 70% humidity, E10 can absorb enough water to phase-separate. The shelf life of E10 is only 60-90 days if left without treatment

Good question. I've done very little with my tuner on my setup. Mostly because we are switching turbos this winter, and some other things - I like to be respectful of the dude's time . For now it is a non issue as I'm starting to bleed down to Shell V-nitro.Do you have the cold start ethanol tables in your tune?
As always, thanks. I think this discussion has borne out two things for me:This is for E10 but the more ethanol the bigger the problem. I definitively would not store a car with E85 in the tank. Pickeling the system with gas is normally what is recommended

Since this is my thread to abuse, I'll mention that I've been running Hot Shot's Secret FR3 (friction reducing additive) in both my diesels. After a few hundred miles it is unbelievable how much quieter both my N57 is (which is already quiet) and my wife's bluetec MB diesel. It is astonishingly smoother. I've always been somewhat suspect of additives. But this company has a great reputation (it's Stiction Eliminator which diesel guys use with the oil pressure driven injectors, has a huge reputation, for example). I may consider running that in the N54 as well. While my car doesn't see many miles, it gets a harder duty cycle given the way I use it.
- I'll continue my 3k oil changes, move from Motul 8100 to Motul V300. I may do a Blackstone test at 3k when I switch out of 8100 and have substantially run E85 for 3k miles.
- In the spring I'll look to run fuel additive with E85.

Agree!I would think storing with a quarter tank of gas with some stabilizer would be the way to go. Then just fill up with fresh fuel, at the end of winter and take it easy on the first tank.
Sorry my post may not have been clear. Not looking to run that in the N54 - was just using Stiction Eliminator as an example of the company rep. I've run it on my 6.0's and 7.3 Powerstrokes.The stiction eliminator has a great reputation think i saw it on Jay Lenos garage. I would just check on the base before you run it if its diesel based it may not pass through gas injectors.
Once we have the new turbos and get into tuning, we'll see where we land with the tuner. I'm running Motiv FlexFuel solution btw. I'm shooting for circa 600whp with upgraded twins, PR ignition, DI only, VTT single barrel. Hoping to do that sub-25psi. Most of the car is built up to support this - this winter plans are turbos, outlet, single barrel, Motiv clutch/pp, 3DMMotorsport prototype aluminum guibo, and PR ignition. I had the BL ignition and sold it, so on Eldor coils now.Not sure what your power goals are can you run E60? More gas would mean less ethanol
Great question. Honestly I'm 98% sure I know the answer, but I'm not looking to discuss that for another six weeks or so. I'll speak up soon.What turbos are you getting?
Marty, I hope that's not the case. I don't want to run two fueling systems (PI) or two fuel control systems (IAC). Dual HPFP development work, to be controlled by the factory DME Hardware is underway, the but unclear if that will come to fruition.I think you will need more than a single barrel post 22psi, more likely a double barrel on straight e85.

I'm thinking in terms of fuel pumps, mostly, maybe injectors. I did a $14,000 fuel system (tank to injectors) replacement on my BMW diesel at 24k miles. Lubricity is a known issue with modern fuel pumps. I love science. But it catches up with problems, often. Unfortunately in the meantime, it doesn't pay the $14k bill.

When it comes to whether fuel additives maybe worth using, the chemical engineer in me wants to first know the composition of the stuff, which sometimes can be ascertained from its materials safety data sheet (MSDS) which manufacturers are required to provide. Although the MSDS doesn’t give a complete recipe, you can glean whether there’s some really active stuff in the additive, or just a mixture of different solvents. In the case of Lucas Safeguard ethanol fuel conditioner, the MSDS seems to be just solvents (like gas) to help keep any water stay mixed in and not attack the fuel system.This is the kind of stuff I find disconcerting, and maybe because I don't understand the subject well enough: (https://lucasoil.com/products/fuel-treatments/safeguard-ethanol-fuel-conditioner-with-stabilizers)
Lucas Safeguard ethanol fuel conditioner cleans up ethanol issues. Whether you use E-10, E-15, E-85, pure ethanol, or any mixture in between, including gasoline, it can be stabilized to prevent varnish and gum formation. Safeguard cleans injectors, valve seats, combustion chambers, and other critical fuel components. It combats deposits and protects your engine's lubricants from the harmful effects of alcohol combustion. Plus, it's completely soluble in all ethanol fuels, will not harm your filters, and contains effective additives to prevent the rust and corrosion associated with ethanol fuels. Condition your fuel with a product specially formulated for problems with ethanol--Safeguard from Lucas Oil.
So half the things this discusses are gasoline (not ethanol) issues. Nothing is mentioned about lubricity, and for that matter, the fuel system. For an ethanol specific additives, their description doesn't exactly leave me feeling warm and fuzzy. Requires being a chemist and material engineering expert to deep dive if the product actually addresses what is needed.
