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

[HEMIMANN]

I honestly don't know, "good" can be a little subjective when it comes to this. I personally am far less concerned about the filter than the oil itself. I'm running the smaller Fram Ultra which is synthetic media and silicone ADV and I'll run it to my next oil change, which basically means I'd have it for about 12,000 KM or 7500 miles (half year of driving for me). I'm perfectly fine with that, it's good enough for me, but obviously the bigger Fram Ultra (XG2) and the bigger RP options are definitely better.

Talked about this with @Wild one - you'd hafta set up a differential pressure guage across the filter media to see whent the filter bypass valve opened from media being filled.

That said, extra media may be overkill for contaminant-holding capacity @ 5,000 mile OCI, yet there are still benefits to more media surface area = more total flow opening = less flow restriction for the period of time up until the filter plugs to the OEM filter media openings.

Kapisch? Less likely to bypass during cold weather startup, yadda, yadda.....

Interestingly, I tried three Walmart's in my area looking for an XG2 or XG10575 and they were just empty spots on the shelf. And apparently, Auto Zone and Advance Auto don't carry anything but the low-end Frams.

9 bucks amazon, that has to be the best deal on a synthetic filter that arguably came in at the top of two tests we posted here. If it is proven over time the "new" media is indeed microglass and nothing else, I can see this filter being every bit as good as 20-820 but at a cheaper price.

Walmart shows the 20-500 RP in stock, how does that compare to the 10-48 size/20-820?

 

[runamuck]

I only use Mobil1 in all my vehicles. use 5w20 and the Mobil1 version of the oem filter. truck runs fine even towing in 100*+ texas heat. 50-52# usually. but I also just run regular gas too.

From @HEMIMANN 's post in the oil thread months ago:

10-48 = 28.21 cu. in. standard size
20-500 = 37.95 cu. in. oversize length +34% volume
20-820 = 45.60 cu. in. oversize diameter +62% volume

Which mobile one product do you use being that there’s so many of them? Here in a couple weeks when I do my oil change I’m gonna use the mobile one extended performance because even though I don’t plan to run that many miles that they say that’s good for, I just figured that would be the one that would probably have the most additive in it because it’s “designed” to go extra long OCI’s.

I guess in a way I’m still kicking around the idea of that mobile one oil filter for our trucks but being that there’s just so much praise about that Fram XG filter, that’s probably the one I’m gonna go with. I would just really like to know how that filter compares to the XG2 and even though that is supposed to be a better filter, is it that much better that it makes the regular XG inferior to it or is the XG2 only just better to the point that the regular XG is still considered a good filter.

Ah crap. Forgot the 20-500 was in that thread. I can get the 20-500 RP from Walmart for $12, and they have 5W-30 PUP for $33/5Qt. So I have $76 in my cart, for 10Qts (as 2 singles came to almost $30, while 5 is $33... So I'm getting 2 5's this time, I'll do 1 the next, and if the math tracks in my head, It basically works out to me only needing the second 5QT every 2-3 changes, as I will have 3 QTs left over. And my change interval is going to be 5k for a while, which I do in 4-5 months, so the oil will only sit in the garage for at most a year before it gets run, if I don't dump it into the mowers.)

You will be able to go longer than 5k with PUP and the RP filter, myself and lots of others have our oil regularly tested, I average a bit over 9k per oil change.

Here's a thread with lots of results you can browse through:

And here's my latest result (PUP 5w-30 and RP 10-48 which is the worst one apparently):

I just can’t push myself to go that many miles. Not with an engine that has a known problem of feasting on cam shafts. But, I will say though, at least you have an oil analysis report that is telling you you can so there is that but still… Lol.

I plan to do an analysis eventually, but until then... Plus, I just did my last oil change myself for the first time, at about 62k, and that is the first time where I actually know what was used, other than "full syn 5w-20". And like @corneileous said, I can't un-teach myself the 5k rule, until I get my own results, and even then, not sure I love the 10k when the engine has a rep for doing rude things to itself. I also am looking at it as "cheap insurance". The extra changes when I do them, still end up only costing me a few $ more than I was paying the oil change places for the "dealer interval". Versus the cost of a new engine.

And to be honest, I only actually understand the bottom part, and the report saying "you can go 11k on this".

Lots of data around:
https://www.ramforum.com/threads/blackstone-used-oil-analysis.113465/

My truck has been on the PUP/RP combo for over 50k with the same average oil change intervals, I'm just about to roll over 100k and I'd still do it all the same (except I'd change to a bigger RP oil filter now that I see how much @Burla hates the 10-48).

It's the small size that's the problem - plugs too quickly. Flow restrictor.

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.

I mean I understand, I've been on that filter for just over 50k without problems, but I am switching to a bigger filter now with a remote mount.

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).

If you're doing a remote mount,have you considered doing a dual filter remote set-up. I started with a single remote,then switched to a dual set-up,and wouldn't go back to a single remote again.Oil pressure is higher with the dual set-up,and on my truck,the oil temps also dropped down to where i'm more comfortable with them. I went with the 3/4-16 thread pitch nipple,which gives you more options for big filters,plus you can find the filters in the middle of nowhere,lol

I am switching to the bigger 3/4-16 filter, but just a single 30-8A, I'm using Improved Racing parts and setting it up for the next mod to be adding a thermostat and front mount cooler.

Are you upgrading to the Hellcat or Melling oil pump.The few guys who've tried running an external oil cooler with the stock oil pump,have ran into low pressure issues.

Wasn't planning on it, and I haven't heard that here anywhere. Where are you seeing that?
