And the K&N oil filter apparently has good oil flow, which is one of the main things to look for.
There are also a few other thing to look for. Does the adbv function the way that it should? Too many dry-starts will cause the engine to wear more quickly than it should. Does the bypass valve function properly?
I may not be an engineer or a lubrication chemist, but I saw with my own two eyes a FRAM oil filter that had a nonfunctional advb. I also heard with my own ears start up noise when I used FRAM oil filters. And I have nothing against FRAM. I used FRAM oil filters for a long time. I was a FRAM guy. And if the companies I believed in had continued to make good products, I would probably still be a company guy. I am not a company guy any longer. I use what I am able to determine is the best at the best price, regardless if it is FRAM, Purolator, Hastings, Baldwin, Amsoil, Hard Driver, Mobil 1, Wix, Champion Labs, or whatever.
We do not know what the final results of the BOBISTHEOILGUY oil filter tests will be. At the moment, K&N looks pretty good. This will presumably continue, but if at the end of the testing, perhaps a Purolator Premium Plus looks just as good (at a better price), then I will use the Purolator Premium Plus.
kctom has really defended the FRAM. That is fine-he can use whatever he wants. There was a time a long time ago when I would have defended the FRAM. But it seems to me that there is a considerable amount of information leading to the conclusion that maybe the FRAM is not so good right now. That is fine also-I have moved on.
