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

Yes, the longer Fram is 10575, I think. Look at my chart.

Nobody I know has test documented the correlation between flow restriction change and media area.
@Wild one and I were chatting about a differential pressure gauge, but it'd take a lot of work to rig up. That kind of effort we would only have done at work with company resources and time.

You can ask members when they experienced lifting ticking starting with the small OEM filter (@Burla and you early members discovered it 1st - I'm merely repeating their observations, which make sense to me).
The XG10575 is 4.06 H x 2.981 OD. Bypass is 16-20 lbs.

The XG10060 is 3.33 H x 3.0 OD. Bypass is 9-15 lbs.

20-500 or XG2 got it, I am sure they are both great filters.

I am just a creature of habit, the 20-820 has been good to me so I want to keep running it if I can. Hard to believe I can't find any.
You're in such good luck
I'm local (Scottsdale) and I have 20-820's if you want 1 to hold you over for a year I'll sell it to you. Sent you a pm.

I’m assuming this is in reference to the 10-48 royal purple oil filter but does this also apply to the XG10060 Fram oil filter as well? If so, is this only a real possibility with long OCI’s? This is probably the filter that I’m gonna start using from now on unless someone convinces me the royal purple 10-48 is perhaps better but I’m still only gonna be changing my oil after 6000 to 6500 miles.
If you're die hard set on fram use the xg10575 or xg2 IMO

Wasn't planning on it, and I haven't heard that here anywhere. Where are you seeing that?
Hi-po Ram facebook pages,and a buddy who ran one on his stock oil pump.The stock pump doesn't flow enough volumne to feed an external oil filter with cooler,and keep the engine supplied with enough oil to keep the bearings happy. My oil temps hardly ever get above 200F with the dual set-up and the bigger 30-8A RP filters.Your call,and i hope it works out for you.

Well I am combining the larger oil filter relocation kit with a reduction in average air temp by moving 2/3 across the country in a few weeks, so that should help also. Cross country tow with the bigger filter should be a good test for the temps.

Take a die grinder to your remote kit,and smooth off any sharp edges you can get at.Oil flow hates sharp turns and sharp edges.The couple Improved Racing kits i've looked at,can definitely benefit from some porting.

It's also fluid dynamics - anything between the pump and the pressure sensor is a restriction, so you'll want the largest cross sectional area lines and cooler core you can make fit.

The other thing to think about is mounting the cooler higher than the remote oil filter location, otherwise you'll have flow issues when draining your oil. Either that or some kind of petcock at the lowest point in the system.

Did you ever hear why Chrysler put such a marginal oil pump on such a marginally-lubricated engine? Just bizarre to me.

I mean, I can understand moving the cam way up for siamese valves plus VVT cam phaser, fine, but then starve the already-starved valve train? Huh? Really?

If we only could have gotten a DOHC V8, life would have been great. Oh, well - on to lithium.

**** I was gonna try and get one guess I’ll keep the 5 20 for now side note I’ve noticed after truck sits for a day on start up there’s a chatter or almost flutter I can prob get vid of it as I’ve been laying low for a few days.

At this point, I’m not necessarily dead-set on anything but with me having a lifetime warranty, the XG10060 is what I’m going to use if I use Fram. I just don’t want to take a chance with those others so between the RP 10-48 and the Fram XG10060, which ones better?

No kidding here. I think there are just enough trucks with hemis that lived that they didn't need to make any changes. Mines been fine for now but I just rolled to under 55k miles. Lower miles I think compared to most members.

As my miles jump up, I'm expecting more issues. Sad to say

Filters of equal surface area have been shown (Donaldson test rig, if I recall) to be far less restrictive to flow with wound media than sheet media. The holes are smaller, but there are far more of them. Analogous to uniform PAO oil molecules compared to refined crude.

So - we do not know the media surface area between the differing OEM-size oil filters Fram Ultra XG 10060 and Royal Purple 10-48, unless someone wants to dig through the Oil Filter Thread to see if it's there.

We know, from both advertising and cut-opens, the Royal Purple Oil Filters are wound fiberglass media.

Fram dances around with flowery marketing descriptives of their Ultra Synthetic Media, stating only they are "dual layer synthetic". Cut-opens do not appear to use wound synthetic media - they appear as a matted fabric.

We do not have flow restriction data, either new or over time used.

Conclusion: go with Royal Purple based on optimum media construction for efficiency, flow resistance, and durability (fiberglass does not degrade with time/temp/contamination).
Note: oil filter efficiency testing shows Fram & RP are a near match when new, best in class above all others. This does not equate to equal flow resistance, however.

So just outta curiosity, if I'm going to spend 18 bucks for the RP 10-48 vs 8 bucks for the Fram XG10060, why wouldn't I just spend close to the same amount as the RP and get the Amsoil EA15K50? How does that filter compare to the 10-48? BTW, that Amsoil filter is the one Amsoil says is the OE replacement for my truck such as the Fram XG10060, RP 10-48 and the WixXP 57060.

Royal purple can be had for a lot less than $18. [edit* saw the 10-48 is $18.99 currently on amazon, no way i'd pay that] Check other places, royal purple direct.

I got my 20-820's for $11.99 which, vs. the proper sized frams of xg10575 ($11 in wally world) and XG2 which was $8... its a marginal increase.

plus 20-500's are also $11.99 on amazon
Amazon Royal Purple

Also check the oil filter thread.. it's been beaten to death about filter sizes.

Well, ya know of any place cheaper because Royal purple direct has it for 12.99 but when you add in the cheapest shipping, that bumps it up to over 23 bucks USPS shipping which isn’t even Priority and that’s not even counting the tax if they charge it. My local Oreiley’s just down the street has it for 18.99 and this Mercari website has it for 12 bucks but when you add in the $6.18 for shipping, you’re right back up to little over 18 bucks not including if that place charges tax, too.

But anywho, if it’s a good filter as far as filtering better than the Fram XG10060, the Amsoil EA15K50 and the Wix XP 57060 I’ll just run down to oreiley’s and buy it and by the way, I could care less about the size because I’m only going after OE sizes. I’m only asking about which is the better filter.

Royal Purple is usually $12.99, Amazon or Summit Racing. I believe @Burla said Champion Labs makes the same filter for Royal Purple and Amsoil.

AND - Amsoil is saying it's too small, which is what we are all saying. Don't use the tiny OEM size filters.

Amazon has it for 18.99 and even with free shipping from my Amazon Prime account, tax is still gonna put it over 20 bucks so I might as well just run to oreileys and get it there if I use that filter because even though your right about Summit having it for 12.99, with shipping and tax, that’s gonna put it over 25 bucks.

But ok, I went on Champion Labs website and ended up with a bunch of brands to click on so I assumed the Champ Quality filters was the one to click on and after being directed to that site, I punched in my vehicle info and it came up with the PH48 and the PH48XL so I’m assuming the PH48 is the OE size, correct? Where do I find that filter?

What do you mean Amsoil is saying it’s too small? But I get it, the bigger filters are better, I just don’t want to take a chance with my warranty low and behold something happens and see from my receipts that whether it’s the bigger filter, they’ll probably see real quick that those aren’t OE filters and then possibly use it against me.

But look, I know you guys have what y’all like, recommend and why you use the bigger filters but for someone like me whether it’s the OE Amsoil, Wix Xp, Fram, RP or that Champ Labs, which one do you think I should ise? I mean, any of these has to be worlds better than that cheap paper Mopar filter. When I was at Walmart this afternoon buying my oil and air filter, I bought the Fram XG10060 but I can easily return it if you think any of those others are better. Thanks for your help, BTW.

Amaoil straight up said to not use their filter on the Hemi. Not sure what exact one?
