Yes, like my car has a 10k mile service interval. Longer intervals like that have to deal with more fuel saturation and carbon deposits in oil. The xp filter came around when i was still in parts sales. The standard wix filter still works just fine for that. I would trust the xp for the new oils pushing 20k.
I don’t know. I was just curious what made the XP special and a bit more expensive. Found the info on their site and a few oil blogs.
Wrong. I've personally witnessed two Fram HP filters cause a loss of oil pressure when using synthetic race oil. Wix and K&N, problem solved. The Wix also has a higher flow rate so they're worth a couple horsepower. The real answer though in a race environment is a System 1.
What did Fram have to say about this ? Did they pressure and flow test it , before they cut it open to see what the issue was ?
I guess I need to dig into it some. I’ve been using the “XL” (extended life) STPs, but still do oil and filter changes at 4k miles. Ya…probably wasting that Mobil synthetic, but life is short
All that tells me is the oil system was marginal , or the story is pure fantasy. If an engine loses pressure due to a filter , I would be checking the Oil pump and Clearances. ALL pressures across the system from the pump to the bearing clearances should be equalized. The filter doesn't lower pressure it can only limit volume downstream [if it is blocked]. If there was a m***ive leakage downstream of the filter [causing a pressure difference across the filter] the byp*** would simply open up ,as long as the oil pump could keep up [most do because they're internally byp***ing via the relief valve most of the time] All HP series filters have a byp***. A engine like a SBC needs approx 3 GPM volume [high revving race engines are approx 10 GPM volume and the pressure of the pump also increases with RPM] HP series filters flow double the required GPM volume and this volume can increase a lot higher with higher pressures [maximum operating pressure of an HP filter is 200 psi] Another thing is the oil [racers have this tendency to use heavy weight oils eg: 50 wt] This will cause the pump to cavitate and make the pump marginal. I had this issue on a very expensive dry sump system [the suction line from the tank to the pump would collapse with RPM [I could visibly see it and feel it] It is seldom the filter, but usually other issues
i have used fram filters on all the autos that i have owned and have not had any problems. Most people just dont change there oil often enough.
Exactly. If an $8-15 part from another brand solves the problem, you don't contact the manufacturer of the offending part. You learn not to use that brand in the future and move on.
i used fram filters for 40 years. i never experienced a problem during that period. i then drank the hamb koolaid and switched to wix. i've been good so far
Very interesting thread guys. Keep up the good discussion. And, I now have another doofus added to my ignore list.
The last Wix filter I used collapsed the can when I removed it at the 5000 mile service interval. I have never seen such a thin steel can. I’m not filter brand loyal, but usually use Motorcraft or a store brand if I can verify who made it, eg Champion (now part of Mann & H), Purolator, etc. Never had an issue with a cam folding up like that Wix in the sixty plus years I have been changing filters.
Looks like MANN+HUMMEL bought Wix back in 2016. https://www.wixfilters.com/Resources/article.aspx?NewsID=4142 NAPA using Donaldson to supply NAPA Gold products is 2023. https://www.aftermarketnews.com/donaldson-napa-auto-parts-announce-new-partnership/ The filter specific tech info on the NAPA and Wix websites is (was ?) great.
I’ve never seen such devotion to a filter brand to the point of picking the fly **** out of the pepper.
To each his own. I sold parts for years and in our area Fram was called the orange canister of death. I have had more complaints from customers about them than any other brand. If you have great luck and full faith in a product then by all means buy it and sleep well. Myself I am in the Wix fan camp. Makes me happy and impresses absolutely no one.
I haven’t used Fram in years, so can’t offer an opinion. But can I ask what kind of complaints you received?
Okay. Here are,literally, the findings of a one minute search of Wix oil filter failures. https://www.corvetteforum.com/forum...2-ls-oil-filter-issues-wix-filter-issues.html https://www.bigblockdart.com/threads/defective-wix-oil-filter.20971/ https://www.thehulltruth.com/boating-forum/1189352-oil-filter-failure.html https://www.yotatech.com/forums/f114/weird-experience-wix-oil-filter-257478/ http://www.saturnfans.com/forums/showthread.php?t=235627 https://www.powerstroke.org/threads/filter-failure-and-oil-leak-wix-51832-for-bpd-kit.1275866/ https://www.powerstroke.org/threads/wix-oil-filter-problem.142882/ Google lists over 1.6 million hits so I didn't check them all. The point is, no product is perfect and lots of car guys have had problems with WIX. Your experience varies.There must be something better to talk about. I've never had a failure with any brand in 56 years of changing my own oil. Lucky, I guess, or my requirements may be too mild to test a filter to the limits. We could argue that the Asian markets have more modern technology than we do or that the American worker no longer really cares about doing a quality job, but these are generalities, just like Filter A is always great and Filter B is ****. Do the best you can. I think this turkey is cooked and we'll only all ever agree to disagree.
Several complaints of rubber gasket detaching upon installation. Could have been installer I guess but didn't see this with other brands. I did experience it once with a Motorcraft but I consider that a one off as I have installed many Motorcrafts without issues. Also had multiple open the box and find surface rust on the oil filter bases on Frams. After seeing the open filter cross section displays of Fram I would not run them. But that is me. YMMV.
Agree. Google Fram oil filter failure and you will get a similar stream. Bottom line- you only see failures in reviews. The average guy changes his oil and is off to other business. No one ever starts a viral post stating I just changed my oil and the brand X filter is the best.
I routinely take my daily drivers to 300K. I always use wix or another high end filter as mentioned but for 15+ years it has been wix. I also start to add a touch of Lucas additive after 120K or so to each oil change. My commute is mainly highway driving, my intervals are 5K or more and the oil still looks like new
I was a little bored so I read the first two. It seems both posters had an issue but the remaining posts were pro WIX and anti Fram. I’m not saying this means anything other than internet ramblings but it is kind of funny….literally.
