Front views and top views of the three Fram filters that fit on the 5.7L hemi. Not sure if this helps ....

Sure does. A good overall showing of the size difference. Thanks for this. Edit. Could you take them out of box and do same top and side view? That would be gold.

Hi. I took those pics 6 months ago when I was deciding which filter to go with on my 2020 Ram. I bought all 3 from Walmart and returned the two that I didn't use. I went with the XG2 and all is great so far. I change my oil every 6 months (don't laugh too hard) with maybe 2,000 to 3,000 miles on the Redline oil. Yes, w/filter about $94 twice per year, but if it keeps my engine quiet, then well, well, well worth it! I don't want to have a problem (hemi tick) and then say "What if I had used that Redline ...?".

I'm with you, bro. Change mine every spring and fall (on a nice warm day!)
As they say, 'oil is cheap, engines are not'!

Lots of guys here retired or working from home not putting on miles anymore. I do same as you.

Yup, have owned truck 4 years but it is a Apr 2018 Build, and I have an amazing 20,400 on the Odometer, a driveway princess for sure. So the oil/filter gets done every six months. Before winter and in spring. Kinda like PMCS (preventive mx) stuff.

LeeD · Aug 29, 2022

Wow that’s low miles. My 2018 just turned 32,000 miles.

HEMIMANN · Aug 29, 2022

2017 with 46,000 miles, but original owner had 13,000 miles the first year , so I'm averaging only 8,250 miles per year, and less since the pandemic and stay home orders.
Never foresaw this. Keep truck longer, I guess.

When working I used to average 18,000 miles a year like clockwork. Changed oil 3x a year.

corneileous · Aug 29, 2022

Dang, I guess I need to cut it back a little…lol. My 2018 has 41,000.

You're really burning up your truck @ 10,250 miles a year! lol

corneileous · Aug 29, 2022

I guess I just like my truck a lot more than them other fellas…lol.

Driveway princess 98.5% to 99% of the time. I combine all trips to one start and roll. Lil stuff, I can get away with moving my Trike instead of truck. Only reason that many miles, I bought the truck on 1 Aug 2018 and took a 4,050 mile trip the first 3 weeks I owned the truck.

ADDED: That is a built on GL 1800 (for the uninformed 1.8L six cylinder), and gets up to 30 mpg hwy, about 27 in town, so not as efficient as many would think, but a lot better than 13-18 in town with RAM. Is kinda weather dependent tho, hee hee.

Just think…. The sad thing is, I probably did average about 10,000 miles per year for the first three years because the oil change I just did yesterday was only for 5500 miles in one year. The oil change before that was only for about 6200 miles or so.

HEMIMANN · Aug 29, 2022

Geez, @turkeybird56 , even my Hog gets 43 mpg mixed roads, 47 mpg highway.

And it's only air-cooled. 1746 cc
Your machine be a pig!

LeeD · Aug 29, 2022

Nice trike! I had an 05 Goldwing but I never got more than about 38mpg so your not doing bad with your mileage. Now I’ve got a 09 Harley Electra Glide that gets about 40mpg. Being retired too most of my miles come from long trips on vacation. I only put about 6000 miles on last year and 2400 of that was traveling.

@HEMIMANN, I will look and see if i still have the XG10575, so I can cut it open and measure the media surface area. I don't have an XG2 yet, as its freshly installed on my Ram.

The XG2 definately has a bigger volume than the XG10575 and 20-500 based on can size.

XG2 = 22.879 in3
20-500 = 20.691 in3
XG10575 = 19.030 in3

XG2 can volume is 10% larger than 20-500
XG2 can volume is 20% larger than XG10575

Pending measurement of actual filter media

I'm curious how these volumes were calculated, and what am I missing.
When I calculate the volume of an XG2, I get 41.8 cu"

I'm just approximating using the ODs as follows;
height 3.984"
dia 3.656"

Not VOLUME - surface area! Volume is not full of media. Only the perimeter is. I'm an engineer, don't need an on-line calculator.

Circumference of a circle is 2*PI*r = PI*d

Height of canister = h

Surface area of canister = PI*d*h

It's not difficult. Look at my summary sheet.

EdGs · Aug 29, 2022

my bad, forgot to square the radius. Brain fart.....lol

@HEMIMANN, is there already a chart of the size of media in the filters?

I do have the XG10575 still. I won't be able to open it for a couple days though, if anyone is curious

I'm not trying to stir up $hit, I'm just trying to understand in my mind.

I know the XG2 is much larger than the OEM oil filter thanks to this thread. And, I've already purchased a set, ready for my next 2 oil changes.

In the post I quoted, perhaps you weren't the originator of the portion that used the term volume.
I'm not an engineer, however; I too don't require an online calculator to calculate the volume or surface area of a cylinder.

So, moving along and trying to learn more...

I believe I understand the rationale for not using volume now, thanks. Again for clarity, we can't use volume unless we allow for the displacement of the media & the internal bypass valve assembly etc, is that correct?

I would think (theoretically) that in an ideal situation, we'd know the actual displacement volume of the internals and then we could base the performance on the net volume of filters A, B, & C.
Would that calculation not be more useful, theoretically speaking?

Please excuse my ignorance but how is the surface area any more useful than knowing the volume, with or without consideration for media & other internals?
