It's like you took the words out of my head! These marketing dept's have done well for the masses & lead folks to believe everyone of their filters is better than the next brands w/o solid proof. I'm just getting tired of hearing Purolator filters are the "Worst" w/o anyone showing a comparable filter that has been tested w/better efficiencies. They're going by the marketing jargon as their "Proof".
How can they say "Worst" w/o any proof of what is "Better" on a similar filter.
I'm under the believe that 99%@46 microns is not bad for a 20k run on a filter. Until I see concrete proof otherwise that's my position & it makes folks head gaskets explode. I've now been told I have a "Weird bug", "disconnect", "Delusional" apparently I said "Fram's a liar", all in the hopes of trying to discredit my position and I've still not seen anything concrete from them & that's why they've resorted to their tactics. They've got nothing... Some here act like if you don't post every word of their post test or their own feelings position they'll come out & do what they do. I have an unpopular view about Purolator & you see the smoke show
. These spec sheets have been absolutely great in what they provide us consumers. But as you see there are plenty here to discredit them.
Anyways, I agree with your position that most would pass the OEM warranty requirements. That's how a lot of these filter manufacturers know where to start is by doing reverse engineering on the OEM filters. They know full well how to make a solid filter. We just have these extended mileage ones now for convenience. I've been looking at those tech filters but I can get the ones or classics a bit easier so I went with them. You have first hand experience of what a cost effective filter can do for the avg engine. I don't think some give them enough credit mostly due to being sold on the marketing but of course they'll need to get their debit cards out to pay more.
I'm trying to get as many of these spec sheets as I can posted on here for others to make an informed buying decision.
