    Default Eolys Fuel Additive

    Any ideas of how many kms a new fuel additive bladder (weighs 2kg so presumes holds approx 2 litres) will do? Current bladder, which had leaked a bit, has done about 50,000km and appears to weigh 600 grams which presume is 600mls. Just wondered how long this remaining 600mls might last. Any ideas appreciated.

    Estimate around 40k kms. (depending on mix of urban/non-urban driving.)
    How did the bag leak?

    Thanks for that info. For history of leak refer to my thread on 10th March under Peugeot 308 Fuel Additive....I probably should be able to refer you to it directly but am a bit of a luddite! Initial holes caused by stones smaller than a match head, this new leak by sand sized particles. How they enter the comparment is still a bit of a mystery.

    normally it would take you around 120.000 km's to 140.000km's before you have emptied the eolys. For the bigger 2 liter diesel it is 180.000 km's. What you can do to prolong the amount is only fuel the car up when it is empty. Opening the fuel cap will inject after 20 seconds of opening a small amount of eolys in the diesel.

    That's good to know re the kms it will do. Only ever refuel when nearly empty and mostly do non city driving. Why is the fuel additive bladder fitted to Peugeots? Other European diesels (e.g brother has a Ford Mondeo made in Belgium) don't have it fitted. Will have to be super vigilant re amount in the bladder. Hopefully the warning light will come on if it's too low!!

    normally the regeneration of the particle filter can only take place when the exhaust gets realy hot. Often done by post injection heating up the engine and therefore also the exhaust gasses. Problem is that even with that the exhaust gasses may not get to the required temperature resulting in a clogged filter.
    The eolys has the effect that the particles already combust at 350C, so much lower temperature and therefore less chance of getting a clogged filter. Of course if you ony do small distances and not allowing the engine to reach its working temperature, eventually the FAP will also get clogged up.

    The amount of Eolys remaining cannot be measured directly and is inferred from the initial fill and the subsequent usage of the car. The initial fill would have been around 2+ litres. Under normal conditions the car should tell you it's empty by bringing up a fault, but it will probably still have a bit more in it. If it runs out but the car still thinks it has some left in the tank/bladder, it might have problems with the regeneration and you'd find out that way. When the bladder is changed, the technician will reset the ECU so the Eolys fill is known again. Since you know it's low, expect problems before it tells you it's empty. The bladders are not easily refillable and the Eolys now used for the models with the rigid tanks and supplied in a bottle (cheaper too) changed, so you'd need to know what you are doing and which bottle kit to order if you ever hoped to top up the bladder.

    Good to get all that info; at least we're a lot more informed and know what to lookout for. Thanks.
