I picked up an oil filter the other day from partsco but iv had a look at it and it seems very short! The base looks right but im sure its not right! Is there a shorter version of them that i may have? Anyone got any pics?

genuine are preferred by most as some after market filters alter the pressure readings

but they are very short filters anyway

Renault changed the williams oil filter particle size to a generic size for all clios, so the renault ones are as bad as the motor factors ones now.


There is no longer a specific williams filter suplied by renault.

I use champion. Its the only filter i had that keeps the oil pressure as high as the old renault mann ones.

I did a massive write up on this in f7power, tested every filter i could find.

The new renault mann ones drop the pressure about 0.5 - 1 bar compared to the old renault mann ones. I phoned mann and they said the particulate filter size has changed.

The main problem i found with most filters was that the oil pressure wouldnt rise as the revs rose. The old renault mann ones would rise upto 4-5 to 5 bar if you really hammered it. The new ones go to about 3 bar and just stay there at a constant oil pressure.

Champion is not as good as the old renault mann ones, but its almost as good.

I have no empiricle data as to how this effects the top of the engine in a real world setting, i can only guess.

I use renault filters on the rallycar and i get 5 bar cold and 2 bar warm on idle, it has never changed since i have had it. Do notice just before a change it drop 0.5bar on these figures all Using 5/40 oil.

I doubt your gauge is working, ive never known a car to idle at 2 bar when fully warm on any oil. Its too high. Book figure is only 1.

Book figure is 3.5 bar at 3k revs at 80 degrees. And thats from a mechanical gauge, not the randonometer mounted in the car.

any ideas on champion stockists pls, also noted my car will tick over when oil hot about 1 bar when drivin about 3-4 bar

Sounds about right that leave the filter the same.

Is it a mann 75/2 or a mann 75/3?

now theres a question :) will check, whats the differences, guessin that the /3 is the newer one ?

for reference, the OE filter is 7700 274 177

and it is a very short filter

Thats a meaningless number as they apply the 'williams' number to whatever filter they decide to use at the time. You have to go on the manufacturers number to get the pore size. And yes the /2 is the old one with smaller pore size (and therefore better filtration) than the /3 which is the replacement.

Interesting. I am going to have to try this out on my next oil change.

I have this exact problem.
Pressure does not rise with revs after filter change.

What is the part no. for the Champion filter?

Its a racetech gauge not the renault one. Car is fine.

The Pipercross ones on ebay are very good, the pressure rises well when hammering it, big improvement over the Renault one I had on before.

The picture is just a generic one btw, the actual filter is short with a nut on the end.

Ooooh. Nuts on the end prove handy when changing :) May give it a go. Did you spot a idle pressure improvement?

Sounds like the gauge isnt calibrated too well.

book figure for 0-60 is all wrong too.........hmm does that mean all the book figures are too? this would make ur argument very weak.

only probs iv had with pressure is if i use shit oil. castrol greatly reduces the effectiveness of the oil, in both pressure and lubricating , as does mobil 1. these are things iv found having tried many diff filters, and many diff oils in a car that actually gets used, not a tickover once a week engine.

So your argument that somone has double the book figure for oil pressure is that its ok, because you can do a quick 0-60 my mechanically abusing your car?

Your logic comes from the same draw as your track day safety.
