Oil flow rate. Plastic E core v. metal core filters.

[53' Stude]

Where were you in 2010? E-core filters were complete garbage out of the gate. Media blowing through the very large openings and incomplete bonding of the "end caps". There was nowhere to go but up. That said, they do seem to have evolved into a serviceable budget filter.

Search the site for e-core failures to see more if you need to.

I call BS on that. I’ve been at my work since 07’ and we used CHAMP LABS filters til’ 2019 never a failure or “media blowout”. Sorry, I cut thousands apart that went 7-10+ miles. May have been isolated incident. I have a CHAMP LABS filter on my spare car 09’ Focus made lte 2010

I’m not saying your wrong but…..

Yes, some early style eCore center tubes had too large of windows, and if the pleats were not tightly spaced they could flatten and blow-out through a window from the dP. eCores seem to be properly designed these days, from the lessons learned in the early days.

your pics appear to be the "premium" SuperTech compared to the "non premium" Champ filter...the Champ filter with XL in the name has (or had) the silicone ADBV...I can't find the blue SuperTech premium oil filters (Walmart always shows out of stock and unavailable) and have used the Champ XL synthetic oil filter for my 2005 GMC Yukon Denali 6.0 V8...

Took more pics, side by side. Supertech has the silicon drain back valve and the Champ has the nitrile rubber drain back valve. I also noticed on the pleats for the champ filter that one side appears to be slightly separated, hopefully the uploaded pic shows it. Guessing that’s the seam. Super tech doesn’t have the separated pleats.

Ah ok. Yeah I got these because I believe Walmart is going to stop selling some of these MP filters. I haven’t seen them at any of my Walmart locations for months.

This is 14 years later and the ecores are well made now

As some other folks have mentioned in this thread, the caveat with louvers is that they are actually opened properly. I haven't been an exclusive user of any particular filter brand over the years, but I have liked and used Wix and Napa filters made by Wix over the years.

The changes that have happened to Wix-branded filters over the past few year have been discussed quite a bit on this forum. The most recent group of 4 Wix 57145 filters I bought from Rock Auto (labeled Made in Mexico with the louver style center tube) appear so restricted that I can't feel comfortable using them. I tried to put a mirror in these filters and check to see if the back side of the louvers was visibly open. Admittedly it was difficult to tell, but the back sides did not look opened well either.

Maybe this experience has me oversensitive to louvers, but I'll be checking every filter with louvers carefully before I'd trust it. At least with an E-core, there is no concern about the flow through the center tube.

Here is a sample photo from one of those recent Wix filters...

Those louvers look a lot like the ones in a Napa Gold 100351 (MH) I have on the shelf, bought for a GM 2.7L TurboMax.
I didn't use it. Used an ecore PF66 instead.

More than every other oil filter made? Do they show on their site, or will they provide if asked, an actual flow vs dP curve?

What filter manufacuerures mean when they say their filter "flows more" or "flows better" is that the filter's flow vs dP curve is lower. Most filters will only vary a few PSI of dP at high flow rates with hot oil, so it won't matter on an engine.

At least “better” could be a hair less parasitic HP loss …
More is a much tougher sell

Agree - have run over a dozen and all held up very well …

The HP to pump all the oil through the engine is pretty small. The added HP difference from a couple of PSI more of dP from one filter vs the other is so small you couldn't really measure it.

Use the Hydraulic HP equation. It takes only 0.175 HP to move 5 GPM at 60 PSI. The HP increase from adding 3 more PSI of dP (63 instead of 60 PSI oil supply pressure) from a filter would make the required HP = 0.184 ... so that added 3 PSI of dP required only 0.009 more HP.

I know all that - point was marketing can make a claim that would mean something legally - but not to a consumer that understands engineering - I’d say most don’t …

Yeah, only oil filter sellers who really don't understand the hydraulic HP stuff wrt the oil pump will try to "claim" that their oil filter is going to give better fuel mileage. And some people will lap it up.

Was hoping to get better filter mileage for less … But guess it’s just going to be $12+ to get the glass over wire that I trust for even 10k … not wanting to concede one more consumable to China either …
There are worse problems these days
