I'm thinking about feeding Gerrard some 2-EHN.

I don't need a power increase, though any extra "go" or smoothness can't hurt... but I'm wondering if the stuff will provide a little extra cleaning power in the inlet and injectors.

When I got the beast I was shocked how much crud there was in the inlet manifold (via the EGR) and in the EGR itself. I get/got? an occasional "EMU" light whenever I booted the beast which went away after a while... and seeeeems to have gone away for good since I cleaned everything out.

Otherwise what do people recommend to keep the internals clean? I may blank the EGR later on (Gerrard is 2004 spec' so I presume I need the "swirl" plate rather than a complete blank?)

I've also seen some diesel "fuel system cleaners" (e.g. Archoil AR6400) in the vein of Redex for petrol cars.. but it seems to cost a fortune and designed for "single use". I want something I can put in the tank every fill up.

Or is it a case of giving in to the "Dark Side"... nothing to do except dismantle the inlet every 6 months and cleaning the crud out?

if your not after power don't bother with pure 2-ehn, although the higher cetane also helps keep the soot down , its not for cleaing injectors at all.
also it can be overdosed and strip some lubricity.
also nothing will really get fed back via egr and clean manifold whatever they say, so other than a spray via inlet nothing much will clean inlet.
if you went with something like millers ecomax or diesel rhino, 2-ehn will be a fair proportion of it anyway most likely(if it states it raises cetane value).
but nowadays a lube is needed, biocide, remove water from fuel etc so an all in one works for most people.
when I run out of my bulk im looking at maybe liquimoly diesel purge for a( every fill up) cleaner as it can be had fairly reasonably for 5l.
id blank that egr as soon as possible.
if your looking for a super clean intake look up into water methanol injection.

ps millers looks like back cheaper again around £60 for 5l and different citrus smell from adds (old one smelt pretty bad)
liquimoly diesel purge under £40 for 5l
diesel rhino £60 for 2.5ltr
smaller bottles of all available but like everything cost comes right down when you buy more.
work out costs of each per tank some may be 55ml per tank I think liquid moly page was 500ml tank(I don't think its necessary at that dosage for an every tank)
I think you know chore sportivo 155 on alfaforum , he has much input in many additive threads.
also the millers vs rhino threads were quite large on there also.

pure injector cleaner ive heard just paraffin in the tank as an additive

also have you had the map sensor out for a clean, worth removing and blasting out with carb cleaner, will look similar to the egr if never cleaned.

I've put some of the 2-EHN in there.

It has quietened down the motore a little... and it's a bit smoother, even trying to be sceptical in case of the placebo effect.

I notice a fair bit more smoke when I boot it.. but then I'm used to benzina, so "a fair bit of smoke" is probably nothing to the followers of the Dark Side. I'm hoping this means some rubbish is being loosened off and ejected.. though it could be just me noticing because I'm looking.

Might have to try the Millers citrus stuff. The 2-EHN has a nasty pervasive smell. I don't like it!


EGR... I have the 2004 model Stilo. It looks like I need the EGR blank with the hole in it and fit it between the EGR and the manifold.. but I've seen some people fit a blank in between the manifold and the heat exchanger.... which to my mind seems the better place to put it (saves gunge drifting into the heat exchanger and the EGR.

Would my ECU notice and throw an error?

You can buy fuel here in Ireland with the 2-EHN already in it - topaz it make a big difference in my van. I presume someone in the uk does the same.

Look at the MSDS for the additives with a lot of them 95% is kerosene 5% additive and you're paying 20 times the price in the small bottle.

You always get smoke in a diesel when you boot it cause the turbo can't spool up instantly but it shouldn't keep going.

Don't know how youe ECU ill respond. Why not try the restrictor plate first? It works on my 06 1.9 16V Croma. And its legal .

ps how much did you add ? I think ive tried doing 50ml - tank and 100ml- tank and same again diminishing returns.

that's probably just the higher cetane causing these effects that's why people who use the super diesels usually notice when going back to normal fuel.
should also be starting slightly better, and produce less soot due to faster / better combustion.
the higher cetane value changes the fuel combustion event so its a real measurable thing not placebo, although I never see any noticeable extra mpg running high cetane.
id still fully blank the egr, check on one of shadeymans threads(or others im sure theres been a few) about blanking plates I think you may get a warning light on dash but no limp mode or restricted power etc, mot getting more tighter but id guess there are many stilos with egr blanked already.
as above, if cost is all, a mix of kerosene and maybe jaso fb 2 stroke for a additional lube(or groundnut oil) .
im still using up a 5l tub of millers I bought years ago(very short daily commute)
once you do a few shots there will be diminishing returns on effects though with any additive , that's why an as sold do for most.
if you get into mixing your own you can tailor each shot or batch to suit your needs.

ps if you didn't like the smell of 2-ehn then the millers will probably stink to you , as I don't remember the 2-ehn smelling at all when doing my mixes. and im sure ive seen a review saying it still stinks even the new citrus stuff, when I was looking for price for you

I have a container of it with a spout that is tricky to use.. so I ended up tipping around 75ml into a jar rather than 50ml. I went with that..

The motor is smoother.. apart from a resonance at idle .. which I think is the wheel arch liner vibrating against the metal intercooler hose/bumper (someone removed the under-tray which would have braced it) it almost doesn't sound like a diesel. I'm pleased with the 2-EHN.

There's also less smoke. Occasionally when I boot it I get something resembling a burning Kuwaiti oil-field out the back.. but most of the time I can't see any smog behind me.

Starts easily, though the beast always has... despite a glow-plug warning which started a few days after I fed it the Viagra, which has to be a coincidence.

I would recommend a shot of it in every tank. So far I've got no downside, other than the stuff smells if you spill it.
