20-500 fits no issue on mine

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.

2013 and newer rams it is a tight fit, some say impossible some say it takes some work but doable kust find the angle. 2009-2012 no problem. Let us know how it works out. I trusted the fitament chart and a few guys who used w/o issue must have been early 4 gen, I missed the fact for the entire reason they changed the filters in the first place to the smaller filter. My apologizes, bad form on burla right there. It is indeed a great filter if you can get it on.

I'd just get down there and look if there is anything within 2 inches of the current filters diameter that will jam you up.

HEMIMANN · Aug 31, 2022

Heck, even two of us with heavy duty 2500's and 6.4 Hemi's mine fits 20-500 just fine, and the other didn't, or maybe I got that backwards - he could fit the biggest 20-820 just fine, and I can't.

The 20-820 is a tight fit as it is, don't remember what is close to it off the top of my head but it's not a real easy filter to install or remove. No biggie I will snap some pics when I attempt the 20-500 install HAHA I actually had two local guys hit me up and offer to sell me a 20-820, very thankful for them! Great community we have here.

I following the path blazed by Wild one. I'm switching my remote filter setup over to the old style 3/4 -16 filter, vs the 20-820, easy switch by replacing the one insert and replacement filters appear to be available.

I have chatted with a few you oil gurus recently but now I am running against the clock. I am about to roll to 8k miles and I need to do an oil change. To be fair, Blackstone has told me to run past 10k multiple times I just have a hard time doing it.

Can't find any RP 20-820 filters anywhere, back-order dates are out many months...

I have ran a K&N before on my truck but the last one of those I ran, there was a defect where oil was leaking past the nut welded on the end of the filter. So that is out of the question in my opinion.

What is second or third best? I refuse to run a Fram because of the horrible videos I have seen on their tear down and inspects.

Ams oil or Wix is all that is left right?

I am sure it's not as big of a deal as I making it out to be in my head, I have just had great results with RedLine 10-30 and an RP 20-820, I really don't want to change it up.

I found a few places with them in stock using Google and other sites say they will be in stock by 9/13.

Damn i'm getting the feeling i'm a bad influence :Big Laugh:

. The 30-8A dwarfs the 20-820 in size that's for sure,plus you can get the old style 3/4-16 filters in the middle of nowhere

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

Or...you could contract with a current filter manufacturer to produce a filter under your own brand. You'd probably pay more for rebranding graphics and packaging, but it would save you acquiring your own manufacturing equipment. You'd have to commit to quantity buys and you'd bare the cost of marketing, but you could inflate the price to your heart's content.

Oh, wait...I think someone's already done that!

Amsoil website recommends the 20-820 for my 5.7 Charger which has plenty of room, so I'm wondering when they'll catch up with manufacturing. I know, I know, use the other brand that's pretty much identical

I'm weird.

For those of you considering a remote filter location, it's one of the best moves I ever made on my old Diplomat Police car! It had a factory engine oil cooler, so I ran new braided steel lines for the cooler, and a remote filter up near the cooler, and good an fittings, and everything is leak free and oil changes are a peace of cake now and I can run a real tall filter of my choice!

As I figured would happen Summit has changed the "expected ship date" to now 9-26-22(was originally today). How many of you are they collecting interest from?

JHoward · Sep 13, 2022

Just a month or so ago Summit Racing had 9/13/2022 as the date for the Royal Purple 20-820 oil filter to be in stock. I won't be surprised if the RP 20-820 will be in stock around the end of the year. Who knows ...

Just wanted to come back here and update everyone.

Finally got around to changing my oil this afternoon using a 20-500 and RL 10w-30. (I work from home most of the time now so I don't put many miles on the truck these days)

First fire up after dumping 6qts in the truck, idle PSI was 50-52, ended up adding a full 7qts to the truck to get it to the top of the full mark on the dipstick.

So far, the 20-500 is no different than the 20-820 functionally and it is way easier to install the 20-500 on my 4x4 1500. Going to send my black stone sample out tomorrow. This might be my new go-to filter from here on out.

Burla · Nov 2, 2022

Nice, I was wondering where you went with this.

20-500 has less surface area than 20-820, however. That's why guys who could fit the 20-820 used it.....until it went AWOL.

I can't fit the 20-820, so 20-500 is what I've been using. It's still bigger than the stock 10-48 size filter.

fyi

I can't update my previous posts filter specs. Here the updated list. Seems the Ultra has removed the plastic mesh backing after removing the metal screen backing first.
I know HEMIMANN goes by filter diameter to estimate filter media area, but there are plenty of cut open videos showing the # of pleats play a significant role in filter media area. https://youtu.be/d5ULRcCNy5E?t=397

I might take exception to the number of pleats effecting the amount of media, as length and width arent the only measurements, you should also consider how thick the media is, or even how dense it is. Thus those filters tested for efficiency would be the best way to judge imo. It may influence the amount of contamination that filter can hold, but I never came close to filling that area up, I think you would have real problems with an engine that did.

Calculate the surface area then you'll have relative filtration media area.
I posted it.

I thinking I'm just going to go with the Baldwin B160 and call it good.

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