Correct Eolys Fluid for 2015 Grand Picasso !! B78 2.0 150hp

Unread post by WillyR »

My apologies in advance if I am posting the same question asked and answered elsewhere, but 20 minutes of searching has not got me to a more correct point.

In ignorance, I never knew until the last few deays that there are several different types of Eolys fluid, and I have a strong feeling that I jumped in and bought the wrong stuff.

My (July 2015) C4 Grand Picasso II B78 2.0 Bluehdi 150 EAT6 Excl. must be gasping for fluid at 82k, although my (non-PSA) diagbox says it still has 400ml in it, so I bought some, and only found out after purchase about the different fluids (STUPID BOY, PIKE.!!)

The car has both DPF - Blue pipe connector plug - and Adblue systems.

My VIN is VF7**************[VIN obfuscated, can be read by forum staff]

Please advise the correct type for this car and engine.

Thanks in advance for your ever-valuable help

Almost certainly Powerflex, but assuming you bought a generic fluid, and it covers all 4 generations, then it should be OK. 400ml remaining after 80k miles is not unreasonable if you only fill the fuel tank from empty to full. I think the number on the tank (1.32) is the amount (in litres) it contained from the factory - so you have possibly used coming up on a litre, and sticking one in and resetting the computer is not a bad idea. Will probably see out the car....

Thanks @Richard.

It was because I had bought a generic fluid that I began to worry. And it was made worse by EBAY telling me that was the wrong stuff for my car. The seller insists it is, and it is almost here, so I will have to look at the can tomorrow, and see.

Regarding the life of a tankfull of Eolys, at 82,000 miles (80k service to be done next week when I have the cambelt changed in France - £1000 cheaper than in the UK), I don't ever recall paying for any Eolys topup at a service, all of which were done at Citroen dealers. Interesting....

Thanks for your help

Good day, @Richard

The potentially wrong fluid has arrived, I am mindful that EBAY says this is NOT for my car, but following your words from yesterday, do the attached photos show that is OK to use? Would you trust it? If not, I will return it and buy one that EBAY DOES like (I will not sue you for your opinion).

This is made in Spain, which, of course, is no reason to reject it, but.... The 1,2,3,4 bit on the label suggests it is good for all engines from the dates shown, but I've drunk snake oil before, and it can hurt.....

Thanks in advance
