I used Toyota oil filters exclusively for twenty years. The engine lasted
225,000 hard miles. I remember I wasn't able to change the oil for over
10,000 miles once. Don't ride me about that cuz the reasons it happened are
not important. I don't recommend doing it. Currently, I am using Fram oil
filters because they are easier to get off than the OEM part. The OEM
product is hard to grip and I have busted a lot of knuckles getting it off.
However, I am a little apprehensive about using it. So far, knock on wood,
no problems. It is a matter of convenience, not price that I use it.
However, I will admit that due to the age of my truck, I have started using
more aftermarket stuff as long as it is the same or better than original
spec. Last year there was a thread in this group about oil filters. An oil
filter test was conducted and here is the web page:

There was another reference for oil filter testing which is no longer
available to me.

The most important reason for using the Toyota filter was that it had an
anti-drainback valve which Fram did not.
Below is a quote from Roger Brown of 4Crawler.com:
Its called an anti-drainback valve and helps to keep oil in the horizontally
mounted filter when the engine is shut off. Why? So that when the engine
is started again, the oil filter will already be full so that the oil
pessure will build faster. Why is this important? Main reason is that the
timing chain tensioner is operated by oil pressure, so low oil pressure =
low timing chain tension, which is not a good thing.
My take on using Toyota parts is this. The items bought from the local
parts store are usually of lower quality than Toyota OEM. Those parts are
cheaper, but they don't last as long and I have to buy them more often,
which kills the savings issue. I want that truck to work as close to the
original product as possible. That is why I bought it in the first place;
it had quality over anything else that I saw available at that time. Why
would I want to replace the parts on it with inferior equipment? I have had
a mechanics that always try to replaced my thermostat with an aftermarket
part. Within six weeks it malfunctions, EVERYTIME! They just don't work on
my truck. That is only one example. There are parts coming out these days
by conscientious manufacturers who recognize Toyota parts must be in spec or
they malfunction. Most of it is in driveline equipment though. I know some
of you will say that the Fram filters work just fine and so far it has, but
I am watching for signs of problems nevertheless.
