The issue isn't quality but lack of warranty integrity : Voiding the guarantee & blaming faultless customers (many of ehom did service at Toyota dealers). Originally Posted By: ZeeOSix If the customer used OEM oil & filters, and adhered to the maintenance schedule, then Toyota must have some...

dealer records show customers adhered to the oil change schedules (as presented in court). Even so their warranties were voided. I'm not sure where this belief that a corporation never makes mistakes? Ever carmaker has at least one case in history of screwing-up.

No I was just making the point that Toyota has voided warranties even if the customer ran Toyota oil with Toyota filter at a Toyota dealer. I run the synthetic Toyota oil but 20 micron filtering (nominal) is not good when I have option of 10 micron (Fram, Mobil) or even 5 (pureOne). LINK: I've...

Amsoil has a published chart showing OEM-branded filters (including Honda) are basically poor.

Okay I decided to bite the bullet and called Fram whose tech told me the [Ultra] filter is: 99% at 25 98% at 20 50% at 10 (aka nominal) For comparison the PureOne had 50% as low as 5 micron. Amsoil Old filters were 50% at 7 micron. I don't know what nominal is for Amsoil Redesign or M1 so I'll...

Except the ISO sample doesn't have 20.001 sizes. It has 20 and 25 sample sizes with no value between, so Fram is probably 99% at 25 micron and some less value at 20 (unreleased). I see Purolator does that same trick with PSF where they say 99% at 25 micron, but don't reveal the 20 statistic.

I'll stick with Mobil. Their tech says 99% AT 20 instead of greater than (not the same thing). I'm skeptical of Fram selling the cheapest synthetic filter ($8) without any loss in efficiency. Where are they cutting corners?

And cut them open. Someone ought to do this, maybe? Then compile the % of torn filters. I thought about doing it myself but lack cutting tools.

Oh. I don't run conventional anything. I use filters & other personal items to round-out my Amazon purchases and reach $35 for free shipping. Last night I bought two $15 books + a Fram filter to avoid paying $6 shipping. Put another way instead of $36 for two books to be delivered home, I paid...

So this is an XG = Xtra Guard filter? I thought they were discontinued & replaced with Ultra How is the media sprayed on the wire? Held with glue? What keeps it from falling back off?

Even if only 100,000 customers had to spend $7000 to replace broken engines is too many. The stories posted all across the net from customers say, "I had dealer records showing I changed the oil on time but still Toyota voided my warranty." In some cases the engine died as young as 20,000 miles...

"Cart filters are low volume" sounds like a good explanation. I'll pay the $20 for the 99% efficient Mobil. Originally Posted By: Garak has Toyota (or anyone else) ever given someone grief in a warranty claim for using an inefficient OEM filter? Yes. There was a class-action lawsuit involving 4...

One question leads to another question. :-) Scanning through my options on amazon I see these cartridge filters recommended for my new Prius: $7 Purolator classic (approximately) $21 Mobil 1 $23 Amsoil EaO The spin-on equivalents for my Honda I4 are $3.50, $11, and $15..... about 50-60% as...

They used to advertise 98.7% at 15 microns (and 99.8 at 20). Now it's XXX % at 15 (unknown) and 98.7% at 20. Did they redesign the filter to capture less stuff?

The M1 tech I spoke to claimed 99% "at" 20 microns (not 99.9 as claimed on the website). I asked for additional info but that's all he had.

also found a graph on amazon that lists Fram extra guard == just 95% at 20 microns and Xtended guard == 97% at 20 microns. Not that great (worse than Purokator classic & synthetic respectively). I wish companies would be consistent in wording. My understanding is that ISO testing uses no dirt...

I found this in a 2007 Mobil 1 advertisement at 25 microns (not 20 which is harder to pass) 99.7 Fram Extra Guard & Pennzoil regular (yellow) 99.6 M1 and Purolator Classic 98.2 Wix regular & Napa gold Mobil is comparing their expensive filter to the cheap ones. They advertise in this PDF they...
