Camry 5SFE motor Oil Filter.

[phil-l-fixit]

For anyone who is dissapointed with the tiny factory type oil filter used on this motor, there is a solution.
I have been running a common Z9 (ryco) or its equivalent for 20,000km
and have had no problems at all. The oil is a little cleaner at the change time though.

I do not realy know what problems I can get with the Toyota's genuine oil filter.
Running bigger filter will increase the total volume of oil. But that is about it.

Am I wrong?

How well an Oil filter does it's job is governed by at least two things.
Firstly, how small the holes in it are, ie screen size.
The second is how much screening material there is (square feet)
The smaller the area, the sooner it blocks up and begins to by-pass through the by-pass valve, ie it is no longer cleaning the oil.
You can only get so much screening material into an egg cup sized filter...
you figure out the rest.
That and the fact that a Z9 is a lot cheaper due to the sheer volume that are sold means that it makes good sense to me to use one.

so...... where do they sell these oil filters? I never heard of the brand name (RYCO) Z9.

You certainly cannot argue with that: bigger filtering area is more efficient.
One more thing comes to mind: pressure.

Filter's by pass valve is set to a certain pressure. That is the reason we look in a chart and buy a specific filter for a specific car.

How do you know that those applications are good for the toyota's engine or at least are the same?

==========================
My question is: just what is going to be blocking the filter element if you're changing the oil regularly?
If you've got that much wear particles or carbon, there are more serious problems elsewhere.
Another factor is the time necessary to pressurize the system on cold start when most of the engine wear occurs prior to pressure building. A larger filter size would worsen this effect, not improve it. There is supposed to be a flap type valve to hold oil in the filter when the engine is off. I wonder if they're 100% effective. I let the oil drain over night when changing, and the filter is empty when I remove it in the morning.
I use Mobil 1 synthetic with 20% Lucas, so there are no cold start lubrication concerns. The oil goes in clean and comes out in good condition at 5,000 miles. I use the Toyota filters. Others have seen over 400,000 miles from their engines using the stock filters.

I am dissapointed. All my old oil filter comparison studies on the web are gone. I hope they come back.

Anyway, one study compared the Toyota (Denso) oil filter with others including two types of Frams, Wix, two types of Purolators, and others. The reason I remember this study is because I was amazed at the quality of the Toyota filter when compared with the others. All the other brands had a folded pleat paper filter. The Toyota filter element was so tightly packed into the canister that the guy had trouble removing the center portion with the filter element from the can after the top was cut off. The Toyota filter element wasn't pleated either, but shaped like 3 or 4 flower petals around the center area with a solid mass of filter elements bent in the same shape inside one another to totally fill the can with filtering element material.

I am sold on the Toyota filter and will never buy anything else.

I simply wanted to point out that there is an alternative sized filter available (Genuine TOYOTA too) to fit this engine. Although I do not want to get into a debate on the qualitiy of brand A versus brand B , for those who wish to compare TOYOTA genuine filters, an extract from the previously mentioned web site may open some eyes.
EXTRACT:-
The Finnish car magazine "Tuulilasi" compared oil filters in its latest
issue. The filters tested were all for Toyota Corolla with A-series engine.

Results in short:

Champion C138 Very good
Clean DO 851 Very good (with size reservations)
Biltema 502077 Good (with size reservations)
Purolator Micronic Good
Teho OK 174 Good (with reservations)
Fram PH 4967 Satisfactory
Motorcraft EFL391 Satisfactory
Mann W68/80 Passable
M-Filter MH 3347 Passable
Toyota 90915-10001 Inferior
Vic C-110 InferiorAgain, let me stress.....I do not want to debate the pros & cons of A v's B.

If ahyone wants to convert to the Z9 filter these are some equiv. filters:-
Motorcraft:- AFL 1
AC:- PF 2
TOYOTA :- 15600-4410
Daihatsu:- 15601-87306

Enjoy

Don't post the results of an oil filter study unless you want to debate the results - and to which you refer. Also, next time post a link:

This study is over 11 years old. The data you posted is meaningless.

You conveniently left off the bold top lines of the website you posted: "NOTE: When reading this article, please keep in mind the date it was written and that the oil filters in question will have been upgraded and revised. Also note that this test was done by an independent European car magazine and the test results may or may not be accurate."

Sensitive people please note:- The answers are in bold to distinguish them from the rest of the text. No other reason!!

Don't post the results of an oil filter study unless you want to debate the results - That is not in the Forum Rules?? I stated my disinterest in BRANDS. The original post was about SIZE not BRAND.

and to which you refer. Not sure what that means Brian.

Also, next time post a link: I did say "previously mentioned web site."

No, This is it:- http://kozmik.guelph.on.ca/gtdprojec...il_filters.htm

That is possible, even probable, but not definitive.

I did say it was an extract, so that anyone who was actually interested is free to go to the "previously mentioned" site and look, as I did.
Anyone would realise that test results are only good for the day they were startred. Things can change while the tests are under way.
I guess you need to make a rule that results are invalid after your idea of a fair time, which would be what? A day? A week? A month?
a year? If you want to invalidate results based on time then define the time line.
Please not that the results of your quoted site,

which could make it meaningless by your own defenition.

Nothing like a lively debate is there.

Good enough. I just wanted to point out the inadequacies of your post concerning Toyota filters. Since you didn't provide any supportive information concerning your suppositions about the old and worthless study you referred to, I won't bother to debate further. My point is made.
