Hi
I have a Mitsubishi Outlander 2.2 D and the fuel additive box under the car is leeking (Again) last time it was changed under warranty but now its way out of time and the dealer is asking £206 plus vat for a new bag! (without fitting)
question is what does this do to the car if it all leaks out and there is none left?
will it do any damage to the engine? the 2.0L version does not have this additive!

any help or suggestions gratefully received.

This will be the EOLYS system. The additive is injected into the fuel about every 300 miles and helps burn the particles trapped by the DPF (Diesel Particulate Filter).

Interesting, I was under the impressive the PSA system drew it in when refuelling?

I take it this is just a 2.2HDi engine then?

Essentially it helps keep your DPF clean.

A quick google to confirm my first question brings up this article, which has the basics of it at the bottom:

Personally if it was my car I'd begin thinking about taking the DPF out, but I'm not sure how hard it is to bypass the warning system for the EOYLS. I'm sure however if I took a bit of time looking at the electronics and the values it's meant to give out, there would be some way to trick it into reading full all the time.

I read it that it measured the back pressure build up when the dpf got clogged up so if it wasn't there then it would not build up the pressure.
But its built into the CAT assy so taking it out would only be an option with a CAT bypass and therefore more issues with warning lights etc

The Eoyls is always present in the fuel. As I said above, it's draws it in when you refuel the car. But if the system is empty, then it tends to bring up lights and bongs and beeps and all sorts.

The DPF is monitored by 2 pipes, 1 infront and 1 behind it. It reads the pressures and decides when it needs to regen. It then regens by post injection, shutting off EGR etc etc

So all the eoyles does is try to keep the DPF clean, but the DPF will need to regen eventually.

I had Focus tdi turbo.
I used Millers additive.
Bottle cost approx £12
Over the period that the bottle lasted I saved £35 due to improved mpg, net saving £23.
Car ran well and certainly on this engine it worked. Mates tried it in a VW and said he didn't get the any measurable improvements.
It seems that it will depend on the engine its added to.

If it empties the engine management system will not allow the engine to start.

You fill it up by.....Filling it up.....Open the cap, pour some in!
