I'd want to know what 'high flow premium media' is supposed to convey? Filtration is about removing contaminants, not high flow. Unless required for a specific application. I suspect there is nothing really special about this K&N filter besides the nut they weld to the bottom >
This thread has got me wondering now. I called Baldwin and got some specs on their filter that crosses with the Nissan O.E.M. Didn't seem all that impressive to me. I think I'll contact Mobil 1 as well to see if they'll tell me the specs on this M1-110A filter.
The Baldwins I asked about were a B1402 and a B1431. Both were 23 microns at 50% nominal and 45 microns at 98.7% absolute.
Kinda wish everybody would just put their cards on the table and not make us have to dig for information like this. I'd rather see what it's made of and view the basic specs than have the perfect packaging and misleading advertising jargon.
I'm also sure even the cheapest and junkiest of filters would probably be adequate for most. I just want the good stuff! Or I at least want to know what the good stuff is, so I can see if I can afford it
You know all these companies selling filters and oil will come up with all kinds of fancy words to describe their products which can be misleading. That is advertisement and that is what they do and sometimes they offer some of their own personal tests and reviews in caparism to other products in which theirs always come out the best.
As for the specs of the filters, they disclose only so much. When you call to find out more info, you will be surprised you will get the run around. Or they will flat out refuse. All those fancy words, they cannot explain further than what you read. That is why I guess you may not get a very definite answer to the exact questions you have. But if you happen to find out something new, would be nice of you to have with us here in the forum.
If oil filters can be classified in 3 categories of Economy, Regular, and Premium, you know Mobil 1 and K&N will both be in the premium class. The others can fall in any of the 3 classes.
This is all based on real life reviews from all car forums and from a well respected website like bobistheoilguy. If you have never been there you should go there and you will learn some things for sure.
When it comes to oil and filters, if anybody would just follow what the manufacturer recommends, one's car should not have oil problems. That is change your oil with conventional 5w30 with a regular or Nissan filter after every 3,750 miles. Truly, anybody who does that will have a clean engine. Nobody can dispute that will not give someone a good and clean engine with tons of miles on odometer.
But as you know in car forums, people wan to challenge manufacturers and do what they think or feel is best for them. Like here for example. This member is using a large filter. Nissan will not encourage that at all. But it is his car and he can do what he wants to it even if he ruins it. But we should know that nobody wants to ruin their car, so people do what they think is good for their cars. Like you are using 0w20, but Nissan recommended 5w30 for your car and mine. Me too I have used 0w40 and will use 0w20 and a large filter now. That is not what Nissan would want or encourage or recommend. But I take good care of my cars and I want to be experimental with the filter. As for the 0w20 oil, I know that will be just fine for the car, same as you knew it would be fine for your car.
Are you also interested in experimenting with this large filter? I am doing it and will see how it turns out.
Do you run your oil for 5,000 or 10,000 miles? I used to run mine for 10,000 miles, but I think I will stick with 5,000 miles oil change on my QX now.
I see you used Mobil 1 high mileage full synthetic. That is one of those oils that will be considered premium. Same as their filter. So, that is why you use it. But I am very sure a Fram Ultra filter and a Pennzoil full sybthetic oil ran for 3,750 miles or even 5,000 miles will offer the same protection as that premium Mobil 1. That is why these things are just personal preferences. I believe they all work the same if we do frequent oil changes not extended oil changes.
