What is the PSI on the M1-212 Mobil one filter? I could not find any specs on their website? Anybody know?

 

Here is what Oreilly Auto's website had for specifications for the M1-212.

 

Burst Pressure (psi): 400 psi

Bypass Valve Pressure (psi): 18 To 22 psi

Filter Media: Cellulose/Synthetic Blend

Flow Rate (gpm): 11.2 gpm

Gasket Inside Diameter (In): 2.39 Inch

Gasket Outside Diameter (In): 2.76 Inch

Gasket Thickness (In): 0.37 Inch

Gaskets Included: Yes

Inside Diameter (In): 2.98 Inch

Removal Nut Included: No

 

I have use PF-63E's, M1-212's, Wix 57045, and Fram Ultra XG10575.

The Fram filter's bypass setting was 9-15 PSI.

 

I have also switched back and forth between 0W-20 and 5W-30. No issue with 5W-30 other than the lifters being a bit quieter and the oil pump slightly noisier (still functioned perfect at all times).

Thanks for posting this info. I have debated between the 57045 and the 10255xp for a while, now that it is 10255 reg and xp, makes a little more sense.

It is a bit interesting though. They are increasing the required pressure of the valve to prevent "dirty" oil from entering, but at the same time extending the function of the filter element. For cold starts I guess it doesn't matter as the pressure is likely much higher, but to someone with very clean oil would you kind of want the bypass to have a lower rating. As well, after a little research there are some filters which have a small filter/screen on the bypass valve. It would be nice to have these oil filter valve sepcifications for other vehicles, when swapping brands of filters. I guess we mostly leave the trust in the parts supplier to provide a properly spec'd filter.

I have a few 57045xp filters in my garage.  Anyone see a downside to continuing to use them?

How many filters?   I don't see an issue running them especially if you do 3 to 5k oil changes. 

 

My take in this is the new oil system on these new engines probably was putting a higher pressure delta P across the filter and causing it to go into by-pass mode off and on so they raised the psi.

Not sure where the confusion is?  GM has the higher spec bypass on the AC DELCO from the git go?  The aftermarket  is what GM's problem is....they say they are not up to spec.............CHEERS!

Not the 'XP' version, but I finally discovered what the big difference is between PF63e, 57045, and 10255XP...about 0.350"-0.400", which when the k-member in directly below the filter, you lose all ability to use a oil filter cup wrench. Install is not an issue as you normally tighten by hand, but removal requires a shallow single size cup or a belt style removal tool. The 10255XP is a lot closer in height to the pf63e. The 57045 is wayyyy to tall. WIX site shows 57045 at 4.828"(measures same in actual) and the 10255XP at 4.776", which is only 0.050" which is like a flake of rust or scrapping the undercoating, it was definitely more than that. I forgot to measure the 10255XP but there was way more clearance as I tried a standard 15-74/76 cup on it and there was no issue.

I have been using a super large set of channel lock pliers.  So I never noticed the problem.  Looks like I have to buy some 10255xp filters.  I may be able to use the 57045 filters in my SS Camaro.

I use a set of Channellock 209's for the filters. Best money I ever spent. Good for plumbing jobs too.

So with a bypass from anywhere of 12-22 psi, does that not seem low? My truck even when warm still hovers around 40 psi at idle. Does that mean I am bypassing my filter all of the time?? Excuse my ignorance, but this simply baffles me. BTW i just checked my maintenance picture log and I used the 10255 filter just this last weekend.

No, that isn't how it works.  The by-pass pressure is the delta P across the filter media.  When that pressure is exceeded then it will go into by-pass, like when you go WOT or when the filter gets loaded up.  The main reason they went to a higher by--pass is because of the new variable oil pump and system.  The filter was going into by-pass more often at a lower setting so they raised it.

So let me see if I am understanding this correctly. Let's just say the filter "fresh" is designed for 60 psi of continuous flow. If the filter degrades, or becomes restrictive over time and you go WOT and the oil pressure climbs the bypass is designed to open at 22 psi above the 60 psi design criteria. This reduces the chance of starving the engine of oil. Or am I still out there in left field?

Long time to wait for an answer.  Sorry. 

 

The first of all a filter is designed for a flow rate, not a pressure. Picking from the air a WIX 51515 (PH8A). Catalog states it has a flow rate of 7-9 GPM and a bypass setting of 8-11 psi. It has a bust pressure of 290 psi. This filter fit dozens of engines including the FE series Ford Big Blocks. Those motor ran idle about 15 to 20 psi but near 70 psi at 6,000 rpm. That does not mean that at idle the 10 psi bypass is in bypass. The bypass pressure is the pressure drop OVER the filter media, NOT the systems pressure. 

 

 

 

Excess flow can open the bypass. That is if the pump were trying to pump 12 gpm through this filler, something that might happen near 6,000 rpm then the bypass would open preventing oil starvation. 

 

Cold oil, like on a -20F day will open the valve. It would be like pumping cold honey through a door screen. It closes once the oil heats and thins. 

 

Percent filter blockage. Yea...that is the red line in the graph. With warm oil and average operating rpm (flow) the bypass remains closed until the filter becomes so plugged the pressure spikes. Eventually left unattended it will collapse and fail. 

 

Use the right filter bypass, the right oil viscosity  for the temperature and  and keep revs in check until it's up the temp and during normal service the bypass stays closed.

I would think that a guy who’s really good about changing oil every 3,000 or 4,000 miles, who never allows his oil to get very dirty, would want the lower bypass pressure because doing so would get oil pumping in the engine a little sooner at start up. Now  maybe this would result in only a 2 second difference, and I’m just splitting hairs. What do you think, is my logic flawed somehow?  Or is the issue perhaps that oil needs to always be filtered as much as possible to help avoid AFM lifter problems that might be caused if a tiny microscopic piece of crud gets in an AFM lifter? I wonder.
