Oil filter question

[bangernom1cs]

Hi,

Just been out to tidy some crap out of the garage and noticed a wierd thing.

The filter I took off my HDi last week when oil-changing is a FRAM 9599 .
The replacement which has been on the car since thursday (and 800miles) is a FRAM 5566a
which I know is from the 1.9Td D8.
I'd bought two filters as the same filter also fits my wifes CityRover 1.4
which has an old Pug (205/309?)petrol engine.
I've checked the filters side by side and there are no visible difference between them physically
and fit perfectly on the engine.

Question is.......Is there a difference between the XU filter and the HDi filter?
Flow for intance or fineness of filtration perhaps? Or even price!
The car itself has run fine with no problems using Valvoline 'MAXLIFE' synthetic
which I also ran in the D8. I only noticed when chucking the boxes away.
(I know that the 405 1.9 air filter fits in a 406 1.9 with no problem and breathes better as the foam layer is missing.)

As far as I know every single Peugeot engine runs the same oil filter (I call it the Purflux filter what the dealers used to hand out).

The HDi filter is slightly different from the other universal filter, the part number is different,I buy the HDi filters from the Citroen dealers in bulk for good discounts, I use the HDi filter for all Puegeot and Citroen engines, petrol and diesel.

There is a Mahle filter listing, a 310 model, this is listed in the book for all Peugeot and Citroen engines, petrol and diesel.

When I say ALL, I mean the screw on type, later type filters are paper element, including the 407, there are several variations of these.

Might be just a simple case of being able to charge different amounts for one part number over another. If you checked the part numbers there will be a whole range of different vehicles those filters will fit.
