Anyone had success with fuel injector cleaners ? Or should I stay away from them ?

cstavaru · 06-16-2010, 04:08 PM

Hi,

EDIT: BMW sells it's own fuel system cleaner - part number 82140413341 ! It's Chevron Techron though.

I am thinking of using some fuel injector cleaner prior to my HPFP replacement, and also replacing the fuel filter just to "start fresh".

My question is, do the fuel injector cleaners work ? Do they clean potentially clogged injectors without doing any other engine/fuel system damage ? Do you have a recommended brand ?

Thanks !

i think someone has done this before with nothing really to shout about as far as results.

Won't hurt..

i use Lucas Octane Boost to every other tank.
it allows the gas to burn slower and more efficiently.
plus it lubricates the fuel parts like the HPFP.
can't go wrong there.
hwy. gas mileage increased almost 2 mpg.

bottle of techron wont hurt

Are you sure you're not sipping off the bottle too?

Got it...found out that BMW sells its own fuel system cleaner under the part number 82140413341. It's Chevron Techron

We have DI, therefore fuel injector cleaner will not work. This topic has been discussed numerous times. The solution though is spraying sea foam into a vacuum hose behind the air box, keep rpm's at 2000 spray the can, keep motor idling for 5 minutes. Shut off the motor, let it sit, then drive the living shit out of it. White smoke should spew from the tailpipes.

Why wouldn't it work ? Can't see a reason for this. Since the gas (albeit not pre-mixed with air) passes through the injectors, it should clean them...

Could you point me to a thread where this issue has been discussed ?

Are you sure about that? Sounds like you're talking about the ineffectiveness of using valve cleaner through the gas tank, where it won't work because of how DI works.

Anyway to the OP, one cleaner that I use is Ventil Sauber by LubroMoly. It's designed for cleaning valves (which, again, isn't effective with DI) and injectors. I've used it on my E30, E36 and my E92. There had been successful tests in European Car magazine on it in the past.

You can not clean a DI injector. They fail because the ethanol in the fuel ruins the internals (the many flat discs contained within) of the injector and then the electronics fail.

I think that you cannot clean the valves, but you can clean the injectors.

So if ethanol is being delivered in the fuel and it ruins the internals, why can't injector cleaner, also being delivered in the fuel, help to clean? Ethanol issue aside, wouldn't it help for any kind of build up? What is it about the construction of a DI injector makes cleaner ineffective but makes it suseptible to ethanol damage?

Not trying to be a smart a$$, just trying to understand, so TIA.

Just looked at the Techron site, http://www.techron.com . They say it also works for direct injection engines.

Thanks cstavaru. I figure it would. I can't see why it wouldn't help somewhat. I mean, so far we've gotten explanations on why it fails and how to clean valves. LOL!

dzenno · 06-17-2010, 01:44 PM

Of course it'll go through fuel injectors..this guy is thinking of valves and cleaning out carbon build up

cstmx_ryder · 06-17-2010, 02:08 PM

I don't think BMW would sell it if it's useless, no?

That would have answered all the questions right there.

Such an opening for so many jokes on that line!

David1 · 06-17-2010, 02:20 PM

Our injectors are not failing because they are dirty, they are having electronic issues. To high of an ethanol % eats away the many chrystal disks that are in a Piezo DI injector. Once the disks are damaged, flow through the injector is hampered and this can not be cleaned. This is physical failure.

It wont hurt a DI injector, but it will not clean a Piezo injector that BMW uses. If they were cleanable, There would be a cleaning procedure to try before replacement. Once a piezo injector starts to break down, it's done.

Ya I know......LOL. I think it will work, but how well, well that's another story, especially coming from BMW, there! hahaha

Cool. Thanks for the explanation, David!
