Oil Filter Media Inspections

If anyone is interested, I ran some filtration tests over a period of four months on some popular oil filters and posted the results here:

Thank you for the work! That's some great information there.

Hey thanks!

It was intended for my own filter selection, then I posted on a forum, then it snowballed as I had filters being sent to me from all over US and Canada to get looked at.
Finally, I had to say enough. I collected 4, 30 gallon trash bags of filter guts and 3-4 gallons used test oil to clean up my little workshop!
I still have about 25 test tubes left over and most were reused multiple times. I ran a lot of these tests over and over... but only photo'ed the highlights.

 

wow good job? I use the toyota oil filter is that the same as delco or denso?

 

Toyota owns Denso. It's a Denso if it's like OEM and not the TRD version.
(AC/Delco is completely different.)
The Toyota/Densos in all these tests were a 90915-YZZD1s.

You can also buy a Toyota TRD filter from the dealer parts counter if you specifically ask for it. (or order it online) These vary by manufacturer and design, but the PTR43-00080 I use on my truck, is very similar to the K&N and Royal Purple filters and is US made.
I did not test any TRD filters, but my part number says on the box that it is 98% efficient @ 20 microns. I expect these TRD to filter better than the OEM standard filter and still have good flow characteristics...but they cost quite a bit more, too.

 

Thanks a lot I had no idea they made a TRD filter. I like using as much toyota parts as possible so Ill get the TRD next time.

Thanks again

 

TRD = Toyota Racing Development (you probably already knew that)

Might want to give them a call, they usually have to get them from the warehouse if you go the dealership route. Might take a day or two.

This is the one I use because it says it subs the 90915-YZZD1 I would need:

Looks like my PureOne scored well. Been usin' them for years with no issues. Gonna stick with 'em.

 

Consistantly did excellent. Seems to be a strong correlation between these filtration tests and factory rated efficiency--when you can get factory ratings.
These tests were more to indicate the relative filtration on those filters that don't give any meaningfull info.
A lot of types say "great quality and excellent filtration" but don't give any SAE ot ISO test efficiency at specific micron particle size, nor specify multipass or single pass testing.

Example is the Mobil 1 Extended Performance oil filters. Their site says 99.2% efficient---at what? golf ball size particles? It tells you nothing useful at all. Just marketing hype.
It turns out this filter does pretty well in the tests, but their website sure doesn't tell you that.

 

Link is dead, any way for a new one?

 

I just clicked on it and it worked for me.

 

OK maybe cuz I'm on my android.
