Which one is better? Mobil 1 is twice the price, but they both are very efficent filters (PureOne even has higher multipass and single pass filtration ratio).
Is it justified to spend 2x for Mobil 1?

 

I was using Mobil1 filters exclusively, however, they were tough to get in my area so I switched to the Amsoil filters.

 

Yeah, they advertise it as something that goes together with their Mobil1 SuperSyn synthetic... but this could be just marketing BS. I also looked at oil filter studies (fennder published the link so many times ). And the authors said PureOne Puralator appears to be of similar quality as Mobil 1, so I dont know whats the point of paying 2x price for Mobil1.

 

I've web researched filters and found that Mobil1, Amsoil are good. Please explain the test
"higher multipass and single pass filtration ratio" and how it is performed ie SAE ect ??? I am always open to new tech. The more we (public) are informed the filter manufactures will make a lot better filters for cheaper (as volume goes up).

 

I don't know too much about how multipass or single pass performed. I think there might be a little scamm here. PureOne Puralator claims these numbers(www.pureoil.com):
Single Pass Test: 99.7%
Multiple Pass Test: 98%

"What is the Multiple Pass Test?"
The Multiple Pass Test of Life and Weighted Average Efficiency (SAE J806) tests a series of oil filter performance variables using a constant flow of contaminated oil through the filter. It measures the media's ability to remove fine dust from oil over an extended period of time-not just the first pass through.

"How does the Single Pass Test differ from the Multiple Pass Test?"
The single pass test merely passes fluid containing tiny glass beads through the filter media. Any beads that pass through are measured to determine the media's efficiency.

In Purolater's opinion, the Multiple Pass Test is much more representative of real life conditions than the Single Pass Test.

Now looking at www.mobil1.com you see the following numbers:

The filter box shows single-pass efficiency and multiple-pass efficiency data. What do these numbers mean?
Oil filter efficiency in a circulating system like your engine is rated on two key factors: The size of the contaminants you want to remove, and the number of passes through the filter needed to remove these contaminants.

For a single-pass test, an oil sample is intentionally contaminated with glass beads in a known size (very small beads in our case). The oil is then passed through the filter and the level of contamination is measured after filtration. The Mobil 1 High Efficiency Oil Filter has a single-pass efficiency of 98 percent for 10- to 20-micron contaminants vs. an average of 85 percent for conventional filters.

The multiple-pass test is similar to the single-pass, except oil is repeatedly passed through the filter. In a circulating system, the oil flows through the filter many times, so multiple-pass filtration is often used as the more important comparison vs. the single-pass result. The contaminant used for multiple-pass testing is a standardized test dust. The Mobil 1 High Efficiency Oil Filter has a multiple-pass efficiency of 96 percent vs. an average of 82 percent for conventional oil filters.

------------------------------------

So it looks like Puralator filters more particles....(% are higher for single and multipass test). BUT, mobil 1 talks about the size of a particle being 10-20 microns, and puralator is not being clear about particle size (maybe they are trapping bigger particles??).... ALSO, they use different SAE procedures for establishing the numbers .... so I don't know whom to belive or who has better numbers

One more thing, Puralator gives you BETA ratios, and Mobil 1 does not:

"What is a micron rating?"
Many questions have arisen as to what a micron rating is, and how PureONE compares in this regard with other leading brands.

To begin with, there is no "standard" for a "micron rating." In other words, a micron rating means different things to different people -- depending on who's doing the testing, what type/weight of oil is used, at what rate the oil is injected into the media, etc.

Purolator, therefore, has chosen the BETA ratio-SAE Test J1858-as being representative of its "micron rating." A BETA ratio is a measure of the number of particles that enter the filter to the number of particles that leave the filter. The PureONE filter has a BETA ratio of 7.2 at 10 microns. This corresponds to an efficiency rating of 86.1%-meaning that the PureONE filter removes 86.1% of 10 micron-sized particles and above from contaminated oil-43.5% better than the closest competitor!

 

Purolator PureOne has a prettier casing color then the Mobil 1.

I'm sure they're both fine products, but I haven't seen data to prove that expensive means better.

 

Good job comrad and welcome to the world of engineering skepticisms and marketing hipe.

Slimey
The prettier the package the more it cost,,, think of it like woman,,

 

Why pay close to $10 for a filter? PureOne is $5 and high quality, better than those junk Honda filters.

 

As an aside, I've been doing similar research about maintenance products for our Subaru (2.5 l Turbo engine).

Most of the Subaru folks use the OEM oil filters. Subaru uses Purolator as their OEM manufacturer and the media is supposedly the same as the PureOne product.

One of the most interesting things is the rating of the anti-drainback valve. Subaru has a very high spec for these (in the low-mid 20 range) and many of the aftermarket filters have valves rated in the mid-teens (sorry-I forgot the units-psi I think). While this is fine for Honda engines, people have speculated that using a lower spec anti-drainback valve in a Subaru motor will drain the oil from the turbo and may be a bad thing. Hence, many folks use the OEM filters.

And, of course, others have used aftermarket filters without any issue whatsoever.

Just an aside -- now back to our regular thread . I'm sure fender4 will post that nice excel sheet of all the various oil filter specs for us to peruse.

 

Here's one I like,, punch on "OIL FILTERS"
Also there is some very good write ups on synthetic oil.

Don't forget this one for fun bed time reading

AMSOIL synthetic & filters are good.

 

Oh no! I am/was using Bosch filters. Damn. I cant get any of the others without mail ordering them.

 

Soooo order them,, by two or three at a time and you'll be good to go for a year or so,,, I'm biased to www.amsoil.com,, you can find a local rep near you and he'll take care of you...
