That's interesting efficiency information, though 'for me' I'd like to see it published on the box and/or posted on their website along with the ISO test procedure used, ie,. the industry standard 4548-12.
Apparently they are reading this thread. I just got this e-mail from him today:
Hi,
Just wanted to let you know that our test standard is ISO 4548-12, if you’d like to pass that on to the guys in the forum.
Regards,
Matt
I do agree it needs to be more readily available. Have it on the website at least, or just be upfront and put it on the box.
They are not the only ones though. I know Wix is hard to get exact numbers from.
I have never e-mailed them about it though, this is just from what others have said.
Wix does have some basic numbers on the filter info web page.
As for the "dirty side" explanation, it's a nice one. And it 'may' have been filtered in that case. Of course that wouldn't include if the filter was in bypass. While the latter happens infrequently, it is a possibility.
Lastly I'd just add 'from my observation', if this was another filter brand, IMO the filter would have been seriously flogged for the large area of rust in the dome. My .02
I agree. Probably no problem from the rust unless you are changing the oil when it is well below freezing.
I still would not be happy if I cut the filter open after use and found it.
I think part of the reason there is no so much flack about it is the cost and COO for this filter.
People say "you spent $1.80 on a filter made in China, what did you expect".
If you bought a "mainstream" filter for 2-5x the price, you expect more.
Sounds like that company takes their quality seriously ... unlike a certain other company known to have major quality issues around here.
I agree.
We have seen so many problems with Purolator tears and ADV issues, the company has been notified and known about it for over 5 years.
Yet we still see the same issues and no response from them.
I decided I am going to give these filters a chance, primarily because of their quick response to the e-mail and acknowledging a problem.
I will be trying one of their Synthetic+ filters on my sisters Santa Fe.
It won't be any worse than
the torn Purolator made filter I took off.
Edit: Maybe not, the S4612 for her engine is priced @ $11.33 on both Walmart & Amazon.
Last TG I bought for her was ~$6. I can get an Ultra for ~$9.
If they drop back down to the ~$4.50 range I will try one.
There are still some of the Synthetic+ in the $4.50 range, but several that are not.
^^^ Not seriously enough to keep these rusty filters off the market to begin with. Glad I've stashed Wix and Fram made CQ Blues, Fram Ultras, & pre-"A" suffix Mobil 1 filters for my household's foreseeable future.
But we don't have enough data to know if this was an isolated incident or is a common issue.
Look at the Fram that was posted here a few months ago missing 1/3 of the pleats. An isolated incident.
If that was the first one cut open, you would hear all kinds of trash talking (even though there was some).
In this case, we have hundreds, if not thousands of other Frams posted have not had this issue.
I do agree I wish I had more of the Wix/Fram made CQ filters (Blue or even the Fram made Red).
They were only about $0.60 more than these when they were cleared out.
Disregard what I said earlier. I got on a better computer monitor and was fixated on the staining by the cut edge and not what was inside the can dome end which initially looked liked typical metal distortion from cold forming. Looks like rust to me now that I have a better look at it.
No problem LOL. I think that stuff around the cut edge is oil residue that came off the oil cutter blade.
