All,

The latest results in the continuing series...This time using a Purolator Pure One P20195 filter. First the results, then my commentary...



Based on this one test it doesn't appear that the Purolator Pure One is any better than the Mobil 1 filters, or the Amsoil filters. Admittedly, a lot more data would be needed to be statistically significant, but this data point is interesting considering this filter's reputation as being so efficient at filtering. For comparison, a VOA of this oil was performed by the same lab with Particle Counts over 1.5 years ago. See those results here. Looks like we still have room for improvement!

Regarding the UOA itself, note the high Flashpoint - I have never seen it this high in a UOA of Mobil 1 5W-30EP - almost equal to the VOA above. Viscosity was a tad high.

A Royal Purple 20-400 has been installed on the vehicle for the next UOA. See you all again in about three months.

Wow very interesting Data, I like the particle counts in particular. Looks to me the Amsoil filters are not that "efficient" at least to justify the price, I'm surprised by that. All in all great info and great looking numbers on that truck! That is my oil of choice in my civic, 5w20 flavor though.

I still say B/S's estimated particle counts are not (very) accurate (at all)

For the money IMO the Pure One filter seems like a good deal, especially when you consider the price of the other two filters.

I get 5 qts of M-1 EP and an M-1 filter at AZ for $38. That helps.

I know no one really wants to listen to the Amsoil guy, but really the B/S light method is not that great of a way to do particle counts - PLUS.........to be a valid comparison one needs to pull samples Downstream from the FF filter - and NOT from the sump. We had this discussion when this study started.

A test of the sump is a snapshot in time & reflects how the engine was used in the last duty cycle before the sample was taken. It's not an accurate assessment of filter efficiency & capacity. (All standardized filter testing is done downstream from the oil filter)

The problem, Pablo, is that a lot of people here question many a lab. For example, look at all the people that question Amsoil's tests where their products essentially always come first. Most people here, it seems, take Amsoil's tests with a grain of salt. What lab or what test can truly convince the skeptic at heart?

Are all of these UOA's on the same oil, Mobil 1 5W-30EP?

Would be interesting to see you run a change using the OEM oil filter. This oil is working quite well in your Tundra. I might experiment with filters but I would not change a thing as for as the oil is concerned.

OP thanks for posting-great info

Pablo--this is not a single data point--look at he trend over the years, and Amsoil's trend does not compare favorably with the other filters.

As they say, you can make numbers do anything.................

As I've tried to communicate before, your testing confines will not show the differences and will probably favor shorter life filters.

It all has to do with holding capacity and the perception of efficiency ratings. If you would recycle the filters, you would eventually reach the ratings that the marketing end of things promotes at making them appear "best".

Even with advanced media, a filter with the higher holding capacity with a high efficiency rating will show poorly on shorter bouts ..on the front end of the curve.

A filter's life is on a curve. Your data clearly supports that. The filters aren't near their advertised levels until the end of life. All the filters that you're using are longer life filters.

Given your insoluble level there's no reason these filters were unsuitable for continued use (as much as that would shock some) ..at least for testing purposes. This is showing that under 10k of use (under your service conditions), there is no difference of significance.


UOA:
Noise levels on everything. The UA's are exceptionally low which (oddly) make your results (which are stellar) unremarkable. I don't know if I'd like the silicon ..but there's no AL and other related metals in any amount to suggest anything sinister. Outside of the elevation and drop in silicon with the air filter change, there's no indication that there was a problem.

I think that's the highest flashpoint I've ever seen. I have seen it return to virgin level with an increase in visc. That's easy enough to reason, but I'm pretty sure this is a record holder.
