Anyway apparently Puro either changed the media or made more tests and found the filter is better than previously stated. Boss is 99+, the next one down 99 and the last one a bit lower. Too many numbers changing.
Already explained it earlier. As it's been shown before (by M+H/Purolator themselves no less) that oil filters do not get more efficient as they load up. Increased delta-p can make oil filters LESS efficient.
I don't see an explanation. If a filter is 99+ it is going to have no areas in the graph going much lower. There are no miles on an efficiency graph. If they are saying 15k means 15 grams then 10k means 10 grams.That means 10k is actually sooner on the test, not further along where efficiency bumps upward rapidly.
