I change my oil at 15,000 mobile one 5-w30 I have 328,000 on the clock and it still runs perfect also use Max Life trans fluid synthetic change it every 30-35,000 miles along with the power steering and everything is original...

Even if the oil last 15k the filter is not designed to last nearly this long. I wonder what the metal content is at that interval as well. That's crazy long for my comfort level. This weekend I'm probably going to change mine and install my Fumoto valve along with that Fram XG3600 extended life filter I ordered a while back.

If obscenely cheap full synthetics weren't available, I would be using Pennzoil Platinum or Ultra Platinum (using the 4.5L jugs to precisely match oil+filter refill spec) for the following reason:
Pennzoil Platinum Synthetic is proven to keep pistons cleaner up to 8% cleaner than with Mobil 1 and up to 17% cleaner than with Valvoline Synpower, based on a V6 engine ASTM Sequence IIIG and ILSAC GF-5 piston deposit test using SAE 5W-30. With Pennzoil Ultra Platinum, pistons were up to 25% cleaner than with Mobil 1 and up to 35% cleaner than with Valvoline Synpower.
I don't use a Fumoto valve because I occasionally go offroading and don't want it to scrape against anything or get snagged and ripped out. It's easy enough to get under there with a socket wrench, and I don't even jack up the car or drive up on ramps to do oil changes.
I also believe the OEM Toyota 90915-20004 filter is superior in filtering ability than any other filter, including the filter that supercedes it (90915-YZZD3). Not only does internal construction quality matter in oil filters, so does absolute removal rating percentages at the various standard micron particle sizes. "Absolute" means 98.7% removal in a single pass of a specific size particle in microns.
There are many reports on the Internet of aftermarket oil filters failing - google "fram ultra failure" or another aftermarket brand name + failure. I didn't look too hard, but I haven't come across any reports of an OEM Toyota filter failing. I don't see the point in exposing yourself to that kind of risk and increased cost of each oil change by going aftermarket.
Several people have cut open the 20004 filter and compared to various other filters, and the consensus is that the 20004 filter is of extremely high build quality. I haven't come across the specific absolute removal ratings for it, but I trust Toyota engineers had a good reason to install it at the factory on all 3UZ-FE engines.
if the micron rating is not listed, its safe to assume, for example, if a filter claims "99.8% efficiency", that that is the rating @ 20 micron particles. That could mean a 50% rating on particles 10 microns. The Toyota filter is rated at 99% at 10 microns, and 73% @ 5 microns
The FRAM Ultra filter does not specify any micron ratings - it just says 99%+ filtration efficiency based on FRAM Group (non-independent) testing of average filter efficiency and dirt holding capacity using XG3387A, XG8A, and XG4967 filters under ISO 4548-12 for particles > 20 microns. Any half-decent filter can do 99%+ for particles > 20 microns. If they provided absolute single-pass removal numbers at exactly 20, 15, 10, and/or 7 microns, that would prove their filtering capabilities.
The Fram 3x filter boasts an absolute removal rating of 98.7% at 20 microns. AMSOIL’s EAO filters are absolute at 98.7% at 15 microns with 50% removal at 7 microns. The AMSOIL bypass filter is 98.7% efficient at 2 microns. The AMSOIL EAO filter line is designed to clean oil to a much higher standard due to the 15 micron absolute filtration limit.
Some Toyota engines have become noted as high sludge producers and the high quality AMSOIL filters remove the sludge so well that the filters can plug sooner than the normal 25,000 mile change interval. These engines are: 3.0L V6 (1997-2001 Lexus ES300s, 1999-2001 Lexus RX300, 1997-2005 Toyota Camry, 1997-2003 Toyota Avalon, 1997-2003 Toyota Sienna, 1999-2003 Toyota Solara, 2001-2003 Toyota Highlander), 2.2L I4 (1997-2001 Toyota Camry, 1996-1999 Toyota Celica, 1997-2001 Toyota Solara)
If you would like to use AMSOIL EAO filters, the limit for usage should be approximately 8,000 to 10,000 miles maximum. AMSOIL no longer recommends EaO09, EaO10 or EaO57 Filters with any Toyota/Lexus application.
Low end filters have weak outer casings, paper end caps, and poor quality media. They have high absolute ratings, typically 40 microns. The paper or cardboard end caps and low quality paper media are very affected by moisture which causes degradation of the filter. In general the following filters brands have paper end caps: AC Delco, Car & Driver, Champ, Deutsch, STP, Fram all grades, Pennzoil, Q-State.
Middle of the pack filters will have glued on metal end caps with higher quality paper media. Here the media absolute limit is 20 to 30 microns.
High grade filters have metal end caps, media that is a combination of cellulose and synthetic media or straight synthetic media with a 15 micron absolute capability.
SAE studies indicate that the wear in an engine is due to particulate in the 2 to 25 micron range. Reducing the absolute ratings from 40 microns to 15 microns will lower the wear factor by 70%. Better filters lower engine wear. It is that simple.

The XG3600 is one the best filters out there. Check this thread out. All these filters apply to the 430 as well as the 400.
