What a dirty filter

Pete is a good guy .

Yeah, I've been in touch with him for a while, good and humble fella.

WCW knew the they changed it to 46. No need to know more for his video. Whether he knows the back story, you don’t know.

He didn't know it changed until he looked at the updated website. He probably doesn't know why it was changed. He reads this forum, but doubt he reads every thread and post. Why don't you ask him if he knows the back story.

The reason it was changed being the office staff who answers emails and phones send out 46. Now they don’t send out anything, and the spec sheets still don’t match the other models.

It was changed to reflect the more accurate spec sheets. That erroneous efficiency info on the Purolator website was most likely left over from old Purolator claims. Then M+H stopped sending out spec sheets. They forgot to update the efficiency claim on the Purolator ONE to match the spec sheets. Maybe the M+H pres should know.

Seethe website they say, like all the other filter companies you look at.
Some even look at Amsoil written data, not written by the test company, like Andrew’s numbers. They take that unverified Amsoil data, second hand data, from 2011 and promote it so hard here that in 2025 people still believe the unverified data must have been carved by Moses.

So you think Amsoil's efficiency claims are "unverified". Where you think they get such information. The old data you're referring to says it was ISO 4845-12 information - regardless of how old it is, it was ISO 4845-12 test information.

You think Andrew's ISO 4845-12 is not accurate? You know his lab was ISO certified to do 4845-12 testing. I know you were disappointed (under many different usernames) to see the efficiency claims on the OG Ultra were always accurate. The Royal Purple that Andrew tested (same guts as an Amsoil) came in at 99% @ 20u ... same as what Amsoil claims on their website.

For my HPL cleaning project I was considering the Purolator Boss too. I wish I picked it up. I went with the Fram Endurance.
Boss did a good job here.

 

[Sienna dude]

1800 miles on HPL so far, my target is 6000 miles

So there’s no confusion or conspiracy theories on Boss efficiency. On 1/8/25 I had a lengthy conversation with Angela at Purolator. The spec sheets are 100% correct and automatically updated when production changes occur. This was the last spec sheet I requested before the lockdown.

WCW doesn't know the Boss efficiency was updated by M+H after the pres of M+H got involved with their spec sheets and saw the discrepancy, and said the spec sheets are the correct info. All the stuff that filter caught was big stuff, way larger than 46u. Lots of debris smaller than that got through.

And then all the small stuff goes round and round.....

Particles below a certain size are harmless to the engine, that's why Toyota filters are not the most efficient. Almost 200,000 miles on Toyota filters and my engine hasn't blown up yet

That's not what all the SAE studies conclude - do some searching for said studies. They say particles 20u and below do more damage because those sized particles can get between moving parts easier. And larger particles can become broken up and become smaller particles. Higher efficiency oil filters filter out much more debris 20u and below than an inefficient filter does. Higher efficiency filters also retain captured debris better (ie, they don't slough off as much debris from dP across the media). Extra wear doesn't equate to "blow-up".

Do you know what the efficiency of a Toyota filter is? I know that they are not among the most efficient

The only reference ever seen is from the ISO 4845-12 comparison done by Amsoil many years ago, which showed the Toyota OEM was 51@ 20u. Toyota will never publish or give the efficiency info. That's basically the same as the Wix XP and Boss efficiency territory. IIRC, there was a thread somewhere in this forum not long ago where someone called a filter Tech Line (don't think it was Amsoil), and they also mentioned the Toytota OEM was around 50% @ 20u. Looked for the thread and post, but couldn't find it. Maybe the member that made that call will see this and chime in.

I like the Toyota filter even more now lol.

Quality stuff for five bucks

Because it's 51% instead of 50%?

I use to run the Toyota OEM filter on my Tacoma until I found out what the efficiency was. That's when I went to PureONE, then the OG Ultra after that. I like higher efficiency filters.

What filter did that million mile Taco run?

There's a lot more than just what oil filter is used to get to 1 million miles. Been pointed out many times that the longer the OCI, the better it is to have a higher efficiency filter. If you did 1000 mile OCIs, you wouldn't need much of an oil filter.

I agree. If I didn't drive my van 6000 miles a month, I would look into better filters, thicker and better oils. My van has been operated in pretty much ideal conditions.
There is another member on siennachat forum, his 2022 hit a whopping 385,000 miles. Nothing went wrong with it. He just got fed up with it and traded it in for a brand new lol.

^^^ Yeah, lots of steady cruising on the highway is easy on the engine. Low load (means lower wear), good operating temps (helps keep oil cleaner from combustion blow-by and fuel dilution), way less cold start-ups over the life of the engine, etc. I think the 1M mile Toyota was mainly a highway cruiser.
