Best oil filter?
Genuine Toyota 90915-YZZD3 : Micron ration 20 Efficiency 50%
BOSCH 3330 & FRAM XG3614 : Micron rating 20 Efficiency 99%
WIX 51348 and 51348xp : Micron rating 21 Efficient 99% (at 23 or 35 Microns not sure)
FRAM PH3614 : Micron rating 20 Efficiency 95%-96%
This being said it seems like BOSCH as well as FRAM's XG filters do the best due to having just as low of a micron rating as OEM, yet being 49% more efficient.
What do you guys think?
Also if there are any other filters you think are better or are larger overall for more filtration I would love to know what they are.
Thank you all!

I have run them out past 20k miles numerous times and they hold up beautifully. And impressively, in the 1MZ-FE engine, with it’s stupid filter location immediately under the B2 exhaust header, Fram XG is the only filter I’ve found that will not cook and disable the anti-drain back valve on a longer full synthetic OCI. I’ve had that problem with factory Toyota filters, going 7,500 miles. The Fram will do that three times and not fail. Impressive. Another note, op - you can oversize the 3614 easily, to the Fram 3600, for some added filtration capacity and oil capacity. I do that routinely. The other specs are the same besides height.
I am happy with Toyota filters much of the time. But for a tough application, or were you really care enough to send the very best, the Fram XG Ultra line does deliver as promised.
Also I always change my oil at 5k miles if not before, and every time I change the filter, 6.50 for a filter and 25$ for oil is not much compared to engine problems, at least imo

And I was also thinking about for the "Restore and Protect Valvoline oil", when I watched a test he opened the filter up after 500 miles and it was so dirty that it was clogged

For the record, Toyota filters are perfectly fine for reliability if you change them early, but not up to demanding situations like the MZ-FE engine. Their filtration rate and beta ratio are so-so; but they don’t fail. The fact of the matter is the beta ratio of the filter can be tested, an exact laboratory value established, and there’s no need to “guess” about this stuff or take anyone’s word on it. Many tests show the beta ratio (basic measurement of how finely it filters) for Toyota filters is solidly in the “OK” camp, not any better. So they are OK, but certainly not “very good” or “among the best” among oil filters. I use them on a Cub Cadet zero-turn mower and a Kubota tractor we have, but not my cars that I care about. The two issues with Toyota filters is that they have a poor beta ratio, and the silicone in the ADB valve is not high-grade - which is not an issue unless you are doing long drain intervals OR in a high-heat application. But they are cheap (this should be a clue as to quality - right there) and easily available.
OEM is often good on Toyota parts, but “it’s always good” is a very uninformed approach. I can start ticking off on a hand all the failed and disastrous Aisin, Denso, etc. parts failures over the last few decades that have resulted in massive recalls, destroyed engines, and real headaches. They aren’t god-like, magical, or in most cases any better than other OE parts makers like AC Delco, Delphi, Gates, Dayco, GMB, Tokyo Roki, ZF, TRW, Nissen, etc.
I am running VRP in two cars right now as an experiment; one a long-time oil burner because of coked rings and clogged drain back holes (Isuzu 6VE1 engine). Planning to pull the filter on one of them to cut-open soon, it’s been 1,500 miles or so. I’ll try to post pics and results, let you see if you are interested.

With FREE Shipping and NO Sales Tax, you can’t beat their prices as my local sales tax is over 10%.
I usually shop at Bell Lexus, as they’re closest to me, but have found Treasure Coast to be a few cents cheaper — so for more expensive OEM items, I might have to go with Treasure Coast and risk the shipping from further away to save a few bucks. Haven’t decided yet.
