Renault oil filter Different?

[Chris Lewis]

Fred, you have just illustrated my point perfectly. That filter is the one recommended for the Williams (if that is a genuine renault part). But the original williams filter had a pore size of 10 microns on the filter. That has 25 microns.

Its shows the new spec filters are NOT the same as the originals.

Its up to 172 / 182 owners to test the filters for their cars, i dont know enough about the engines, but i guarantee 100 % the renault filters are not the right spec for the williams and valver engines.

I can drop the oil flow on my car (equivalent to 1 bar drop) just by changing from a champion to renault filter.

Anyway, you have admitted you fit genuine renault filters because you have to. If anyone would like to post up some values of pressure measurements from a f4r with a purflux or mann filer from renault on it i would be interested to see if book figure is achievable. I guarantee you wont get book figure from a healthy williams engine with a renault filter.

I know this is an old thread, but has anyone actually measured oil pressure of f4r with different oil filtersm?

Brave to resurrect this, Chris Lewis might come back to make sure you don't use a genuine filter because it "might" give you less oil pressure?
