RP 20-820 are gone, what do I do now?

[MoparBrent]

For what it is worth this site does show it is in stock and I got all the way through checkout(before inputting my payment info).

I have never ordered from them nor heard of them so take it however you will.

Royal Purple 20-820 Extended Life Premium Oil Filter

Royal Purple Oil Filter features 100 percentage synthetic micro-glass media for superior particle removal with 99 percentage filtration efficiency at 25 microns. This product is designed with a high-performance silicone anti-drain back valve that prevents dry starts, even in extreme conditions...

FYI I did call the hotline (602-314-1983)(Google subscriber) and got no answer. So proceed with caution lol.

Do not purchase from this site, it's a scam site. Quick google search running the site through scam detectors, and checking reviews which 100% of reviews state never receiving parts ordered, as well as looking up the address on the website coming up as a residential home.

Good to know. Thanks for the research.

So what is preferable, low pleat count or high pleat count?

As we know from simulated efficiency testing, pleat count is irrelevant. Scoring pleats only serves as a talking point for sophomoric videographers and the 'more is better' crowd. A chart, any chart, that does not list the filtering efficiency and bypass relief pressure is potentially worthless and/or misleading.

Efficiency ratings are taking from fresh healthy filters, they don't make allowances like they do with oil testing such as noack and hths that put oil under duress to test how oil is long term. There is no comparison between filter medias when you have such an inferior media compared to a media that out lasts any oil. Surface area is also very lacking in how a filter filters, when you see surface area on wix xp being more then rp but you actually see how poor the filtration is in comparison, it is a stat that is clearly misleading without spelling it out, higher surface area is a hindrance to filtering when you don't compare the amount of media. What was the reason for the less surface area, clearly both filters media are not the same thickness, which apparently doesnt make any chart or test, and is the main gauge to how well a filter filters.

There is a old saying that sometimes has real teeth, "a picture is worth a thousand words", sometimes it is that simple.

Bypass filter data doesn't do much either - it is merely the differential pressure across the media that opens the bypass valve. Without dirt-holding capacity vs. time data, it means nothing.

If you start in cold weather, it may be helpful to use a high bypass pressure filter to force oil through the filter sooner rather than later.

I will add that efficiency testing of new filtration media is a useful starting point for filter selection, however. It's just that there is no other data available to differentiate them (flow resistance, dirt holding capacity), so we're left to infer the rest by known physics (wound media less restrictive than matted media, more surface area has more capacity).

This is how we've arrived at Royal Purple and Fram Ultra as 1 & 2. Oh - and also both assembled in USA. Important for quality metric.

A person concerned about the possible resistance of a fully contaminated oil filter, or one who likes to extend their oil changes, might want to know the approximate point oil goes around the oil filter in the bypass mode.

Bypass pressures vary and this could be an indication of contaminant capacity.

Which is measured by contaminant capacity testing.
Bypass pressure only protects the media from collapse, or gasket from leakage.

The only way to know is a test to determine measured contaminant capacity. Would be excellent to mount a differential pressure gauge on running engine filter mount. Lot of work to do properly.

 

[Burla]

One way to actually test bypass is to cut open filters, those filters that tend to collapse is a sign of filter being in bypass a lot. of the three RP I have cut open with up to two years on the interval, I havent see any filter collapse.

I wouldn't expect to see any collapse in a filter with synthetic constructed media just due to its inherent strength. And unless you can determine the media contaminant loading, you have no way to know if and when it ever went into bypass. As HEMIMAN pointed out, "The only way to know is a test to determine measured contaminant capacity."

We now have a couple reports the 20-500 is not fitting some rams, so it would be best to try the fram xg2 until the 20-820 becomes available. Fitament charts have let us down on this one. When those 20-820's become available, consider buying and stocking them, they store well. They can rust if you leave exposed, but in my closet they are like new stored 5 years at this point, put a little silicone oil on the ring to preserve that rubber. The writing is on the wall, this filter might not always be available.

If you try a 20-500 have a back up filter just in case.

@Burla 's e-bay oil and filter store.

I source a lot from China and work with a company that has manufacturing in China, DR, and Europe. I may leverage my sourcing skills and start a synthetic oil filter company lol

The average consumer is dumb as a rock and only buys the cheapest thing available. This is how Wal-Mart and Amazon rose to dominate the landscape, importing cheap junk from outsourced jobs to China.

I'm only aware of Fram & RP made in USA these days. And who knows where their components come from?

Bottom line is most people only care if they save 50 cents. You can see that even on an enthusiast forum such as this one. Saving $8 on 2 oil filters a year because they aren't aware of any issues, though we've spoken over and over how the Hemi is a lubrication sensitive engine.

Oh, well!

Spec out a high quality filter and materials, test samples against RP and XG2, charge 1.5 times the going rate for fram / RP (very likely imports all materials and does minor assembly in us) , show test results in enthusiast markets, carve out a niche (Redline, anyone). Keep your customers informed and happy and maybe make a living lol obviously a little joking, but also a little serious.

Well, I'd support if you did, but I also see how these corporations have squeezed every penny out of their products.

So, like Rockefeller, they'll lower their profit temporarily to drive your new, smaller startup out of business, since you won't have the instant sales volume or mfg equipment to match their cost of mfg.
Once you're gone, they raise their profit back up.

Corporations have been allowed to merge too large again, like the 1900's. It's illegal to sell below cost (Rockefeller was infamous for it), but who's going to enforce that law without breaking them up?

Thats right. But I can tell you this from experience: great customer experience, service, and quality are worth the extra money to certain markets...especially the enthusiast market of many niches. If we charged 17 bucks for an oil filter that was in the top 4 performing brands, it's in stock, it's from a small company that caters to a community's needs, and ESPECIALLY if it responds to feedback...can make a very wealthy small company. Take this with a grain of salt though...I own zero companies, but I have definitely bought into the "you get what you pay for" in many, but not all scenarios...lol

Yep - are those markets big enough to float your boat, is the question.

In this day an age of inflation where everything is so much more expensive, IMO it's a hard choice to willingly buy something that is almost 40% more expensive when there are substitute goods available (economics), no matter the reason.

Of course there are still plenty of fortunate people who haven't been pinched as badly in the last 2-3 years.

 

[Burn2k12Ram]

to the OP @G-Ride990 did the 20-500 fit with no issue? Or are you waiting it out until the 20-820 becomes aval?

I was just about to do an oil change when I posted this but I decided to hold off for a bit because of this issue. I need a backup filter before I swap it out. Maybe tomorrow I will get it done. I am curious if the 20-500 fits on a 4x4 or if that is what is causing the fitment issue. Will let you all know when I get my oil changed out. Which should be this week.
