Mike, using an aftermarket filter is inherently risky in ways that the Toyota engineers understand, but the lay public does not. Here's a real life example of what happened to a Toyota Supra owner who used the Purolator Pure One filter: http://i85.photobucket.com/albums/k75/4af/supra.jpg

This tragedy wouldn't have happened if the Supra owner had used the Toyota 90916-YZZG1 oil filter because it has a 23% thicker and heavier steel casing. Ironically, Purolator actually makes the Toyota 90916-YZZG1, but Toyota required Purolator to build it with a 23% thicker shell compared to ordinary Purolator filters. Toyota also required Purolator to make other changes like building the Toyota filter with an extra durable acrylic O-ring type filter seal that can better withstand engine heat and won't stick to the engine block (and interfere with the sealing capability of a new replacement filter) when the old filter is removed.

Read this carefully everyone... Do yu see what/whom I see?

Maybe yu do!

I am not the lay public. Are yu?

I too have come to the conclusion that the AMSOIL filter is better, and have butted heads with KR on this and other issues. I'm convienced that KR is very biased against any mods made to whatever Toyota you drive. If it's not pure, your doing something bad.

I guess my few mods really make me BAD! But, hey KR, my truck still runs, and runs real good too!

Looks like I'm going to have to do some oil filter pricing research when I head back to Tokyo this summer. Very happy to check the pricing and compare againist the pricing offered over this way here in NA. Then we can see if KR squirms further.

Sanosuke!

You might want to drop by a Toyota dealer while you're in Japan and see if the Parts Depts sell the less expensive made in Thailand Denso oil filters (e.g. 90915-YZZD1 & 90915-YZZD3) or just the expensive made in Japan Denso oil filters (e.g. 90915-20003 & 90915-20004) Or if they sell both types of Denso oil filters.

So what do you guys think about using the amsoil filter for more than one oil change? Has anybody done a test where they just changed the oil and left the amsoil filter in for another run? I wonder if it would maintain it's filter ability for say.....2 OCI of 7500 miles.

 

[Mr. Creosote]

I wouldn't. You are taking a filter full of contaminants and then running fresh oil through it. This is a bit like used needles during a blood transfusion. I would follow the manufacturer's recommended drain intervals no matter which oil or filter I used.

 

[Sigr6]

I agree that the filter is full of contaminants butt the only thing that should be in there are things that were large enough to be trapped in the first place. That being said, I don't think those things would some how be released into the new oil.

Either way, I'll be changing my filter every time i change the oil. I just thought it would be an interesting test.

This is true.

 

[2XOverhead]

This is true.

So long as you change at reasonable intervals, a decent filter will do the job. IMO.

 

[LifeTech]

I want to match my oil quality to my oil filter quality. In the end yu want to know that when it is the correct Time to change the Oil, that the filter has done it's job with filtration capacity to spare.

The Filter supports the oil and not vice versa.

To me, an oil filter must perform it's best especially at the end of the oils life cycle. (OCI) I count on my Filter to not fail me towards the end.

I know this is an older thread but I find it funny how so many here think the Toyota OEM filters are so good, especially the Japan made Denso's that the poster mentioned above.

The results of this test seem to tell a different story.

Oil filter test results!

 

[Stone_Blue]

No offense, but those test results are almost 20 yrs old. There may or may not have been significant design and technology changes since then. Also, based on those test results, I find it very hard to imagine that Fram is a better filter than an OEM Toyota....Heck, I find it hard to believe that Fram is better than ANY other filter out there.

------------- OEM oil Filter Amsoil EaO Filter
>14 microns = 168 particles/ML 12 particles/Ml
>25 microns = 34 particles/Ml 2 particles/ML
>50 microns = 3 particles/ML 0 particles/Ml

These results don't really impress me that much. I've seen three different oil tests (one by Amsoil) and Toyota performed poorly in all of them. Ditto other OEM filters like Honda, Chrysler, Ford.

The fact there are a lot of particles not captured by OEM filter does not surprise me, and I wonder how a Mobil 1 EP filter vs. Amsoil EAO vs. Amsoil EA15k test would perform. (I said EA15k because that's what my car runs.) I suspect the M1 would be as clean as the Amsoil, because the Mobil filter uses synthetic filtering too.

Great info here! I buy my Amsoil at wholesale and it even gets delivered into my garage by my "oil hotty" I'll stay on Amsoil to get info on when they expect to bulid an oil filter for our 5.7's I've been using Fumoto Oilpan Drainvalves on my vehicles since '93,they sure help when you wat to get a "mid-stream" oil-flow sample for a lab.
