This is true (regarding filtered particle size) but Renault have used a similar filter from the R5 till now -I'll stick with the fiat ones, after having one big end failure and numerous reports of F4R's having the same, you're better off having 10micron particles than having the oil filter by-pass open because of a blocked filter like mine did (genuine Renault filter at 600miles from service). Also worth noting: If you buy an aftermarket oil filter eg a Champion for example the filter media used will more than likely be the same for all oil filters to save manufacturing costs.
