How Much Eolys Fluid Should I Use ?

[citrophile]

I'm getting the "fluid level low" warning and wondered how much fluid I will need to put in.

 

Does anyone know how long 1 litre would last in miles?

 

I've done 215k now and I wouldn't want to stick 3 or 4 litres in (at £30/litre) if that would last 80,000 miles as I suspect the car will have expired (or become too expensive to repair) long before I get to 300k miles.

I need to check this but I think it is about 2½ to 3 litres for about 80k miles, so about 30k miles per litre. There was a post that the low message can be ignored (although annoying) and the fluid will continue to be injected as long as there is some. I can not remember who it was but was on a mark 1 2.2 hdi. This will save resetting the fluid counter on the ecu with a Lexia.

Mark 2 C5, amount used in 75k miles should be

- DV6TED4 engine 2.1 litres

- DW10BTED4 engine 2.6 litres

- DW12TED4 engine 2.5 litres.

Also worth noting some of the different types of additive can not be mixed.

 

Modification : Particle filter additive

 

CAUTION : This bulletin concerns only the filling of the rigid reservoir. This bulletin does not concern the replacement of soft pouches.

This development bulletin describes the changes to the factory-fitted particle filter additives and their impact on after-sales maintenance operations.

 

1. The new 3rd generation particle filter additives

Factory-fitted application between RPO 12110 and 12166 (According to vehicle).

Suppliers and brands :

RHODIA : EOLYS POWERFLEX

INFINEUM : F7995

 

2. Previous type of additive

Additive DPX 42 is still available and must be used for all servicing on vehicles that have DPX 42.

When stocks of additive EOLYS 176 run out, it will be replaced by the 3rd generation additives.

N.B. : From 15/07/2010 onwards: Additive EOLYS 176 will no longer be available to order from Replacement Parts.

 

3. Compatibility between additives

Additive DPX42 cannot be mixed with any other additive.

Additive EOLYS 176 can be mixed with additives EOLYS POWERFLEX and INFINEUM F7995.

Additives EOLYS POWERFLEX and INFINEUM F7995 cannot be mixed with each other.

N.B. : As the additive concentrations between EOLYS 176 and the two new additives are identical, there is no impact on the operating calibrations of the engine ECU.

CAUTION : It is not permissible to mix additives INFINEUM F7995 and Rhodia EOLYS POWERFLEX with each other.

 

4. Filling or topping up with additive

4.1. Identifying the type of additive present in the vehicle

CAUTION : Prior to any operation on the additive reservoir, it is necessary to identify the type of additive present in the vehicle.

 

 

Identification by RPO no.

RPO no. / Vehicle / Additive present

Prior to RPO No. 9492 / All types / DPX 42

Between 9492 and 12110 or 12166 depending on version / All types / EOLYS 176

From RPO number 12 116 / C6 / INFINEUM F7995

From RPO number 12 125 / C5 (X7) / INFINEUM F7995

From RPO number 12 152 / C8, DISPATCH / EOLYS POWERFLEX

From RPO number 12 166 / C4, CITROËN C4 PICASSO, BERLINGO (B9) / EOLYS POWERFLEX

 

CAUTION : The only clue is the colour of the clickfit union on the filler interface..

 

Identification by the colour of the click-on union on the filler interface

Colour of the clickfit Type of additive

 

Blue clickfit : EOLYS POWERFLEX

 

Green clickfit : EOLYS 176 or INFINIEUM F7995, (Depending on the vehicle’s date of production)

 

4.2. Rules for choice of additive for after-sales operations

N.B. : These rules only concern the filling of rigid reservoirs with particle filter additive.

Conversion chart for filling or topping-up operations

Additive present in vehicle / Colour of clickfit on filler / Additive to be used in all operations

DPX 42 / / DPX 42

EOLYS 176 / Green clickfit / EOLYS 176 - INFINEUM F7995

INFINEUM F7995 / Green clickfit / INFINEUM F7995

EOLYS POWERFLEX / Blue clickfit / EOLYS POWERFLEX

 

5. Identification and packaging of the particle filter additives

Type of additive / Cap colour in additive kit / part no PR / Packaging

EOLYS DPX 42 / White / 9979.95 - 9736.65 / 5 - 1 litre

EOLYS 176 / Green / 9736.86 - 9736.85 / 3 - 1 litre

INFINEUM F7995 / Green / 9736.97 - 9736.98 / 3 - 1 litre

EOLYS POWER FLEX / Light blue / 9736 A1 - 9736 A0 / 3 - 1 litre

 

N.B. : For any maintenance operation requiring filling of the rigid additive reservoir, it is essential to refer to the conversion chart for the colour coding between the clickfit union on the rigid reservoir filler interface and the cap colour in the 3rd generation additive kit.

 

6. Recommendations/precautions

CAUTION : It is not permissible to mix additives INFINEUM F7995 and Rhodia EOLYS POWERFLEX with each other.

If the additives should be reversed, the filter becomes clogged with particles.

Use these products exclusively ; any other product causes a mmalfunction of the filtration system.

Use clean additive only as any particles risk causing the additive injector to seize.

N.B. : The soft additive pouches have a Part No. and must be replaced with respect to that Part No..

The following data is for the dwted4 for rpo 9276 to rpo 9491 as fitted to my c5 2.2hdi 2001 using eolys dpx42.

The additive pump doses the fuel tank at rate of 37.7ml dpx42 (1.9g of active ingredient cerine) per 60ltrs of diesel. Hence, 5ltrs of eolys will be used up by 7956ltrs of diesel. Assuming a fuel consumption of 10miles per ltr gives sufficient eolys for approx 80,000miles. Hence, the recommended service of 50,000miles/80000km (based solely on additive, not dpf factors) is highly conservative and unnecessary expensive for the customer especially as a low level warning is provided. The low level warning is initiated at 0.3ltrs remaining. The indication illuminates the "service" led and apprpriate warning. Citroen state that 0.3ltrs is sufficient for 6 fuel tank refills of 80 litrs each, thats 480ltrs of diesel, so no need to rush to the dealer or add dpx42.

Here is my actual useage.

At 59,564miles added 0.8ltrs.

At 63,872miles topped up to overflow with 4.2ltrs.(Mainly motorway driving at 50-55mpg).

At 112,773miles topped up to overflow with 2.5ltrs.

Now, at 150,000 miles i need check it again.

 

The much lower consumption up to 112,0000 miles i canmot explain. However, at 75,700miles the additive pump started running continuously and had to be replaced. Afterwards i measured the depth of the additive at 4.5 to 5cm commensurate with 4.5 to 5ltrs remaining, so the pump had not overdosed the fuel but merely recirculated the additive through the pump return line.

 

It would be so much easier if Citroen had used a transluscent tank as have other manufacturers, eg as per brake, coolant and suspension fluid tanks.

By the way, i have never had an additive or dpf/fap warning. I have replaced the dpf only once at 73,144miles. The filter removed was remarkably clean - probably due to daily motorway driving at 65mpg on cruise.

Oops, got the doseage slightly wrong. It should be 37.5ml above, so read as amount of eolys dpx42 to diesel fuel:

37.5ml per 60ltrs (typical tank topup).

300ml per 480 ltrs (low level warning).

1ltrs per 1600ltrs (ie for 1ltr eolys kit, part no 973665).

4.5ltrs per 7200ltrs (ie for 4.5ltr eolys kit, part no 997995).

5ltrs per 8000ltrs (ie additive tank nominal capacity).

Hence, a 80,000km/50,000mile service would assume an average fuel consumption rate of exactly 10km/ltr, thats 28mpg, lets say 30mpg to allow for a margin.

 

By the way, be alert to a garage charging you multiples of the one ltr price when he procures the better value 4.5ltr kits.

Also, ask how much eolys he had to add rather than being charged a blanket cost for 4.5 or 5ltrs. Unless anyone knows different, i do not believe unused eolys needs to be removed (as with an engine oil change), and i dont believe the filling process does that anyway. It merely tops it up and catches the overspill excess so that the amount added can be calculated for the system update. Speaking of which, i have never had the additive computer updated whenever ive added eolys.
