For instance, have you had bad experiences with oil filters in the past? Maybe?
don't know why its personal to me i am just interested in getting a good filter. what sort of bad experiences can you have with an oil filter? you fit it, you remove it.
oftentimes it leaks down your arm when you remove it so i suppose that is a bad experience. i wouldn't mind one that didn't, if there is one.
apart from that i doubt you'd ever know if it was a good one or bad one, bit like oil. i guess most people go by the label. hence its worth reading an independent report once in a while.
Whilst I agree with the sentiment of your last paragraph, I still question the validity of a test carried out four years ago on a filter that is fitted to an engine that isn't fitted to the Omega... Which also brings the relevance of said test into doubt

Perhaps if the test was to be repeated using the currently available filters for the Omega, it might be noteworthy

Not meaning to be negative, but if I turned round and said that in 2011, I discovered that adding a teaspoon of rainex to every tank of screewash made the screen on my Vectra C sparkle, you would be like "So?"
