Think the original links when posted went to some other photo upload website. Obviously non-operational now.

End cap popper DNA tranafere from M+H. The media looks flexible which probably helped it from failing. Louvers look pretty decent. What's the COO on this filter?

I plotted the OEM LS pump curve from the Melling graph, then also calculated what the flow vs RPM would be based on the 0.96 in^3 per revolution volume output spec for the standard OEM flow M295 with 100% pump efficiency (zero slip). Then applied an assumed 95% efficient pump at 500 RPM and the...

This is a plot of oil flow through a fixed flow resistance. The orange line is what happens when the flow is reduced through the same flow resistance - like due to linear rate pump slip going from 5% to 20% in this example. It's the same flow vs P curve because the flow resistance is constant...

I highly doubt the pump is in pressure relief when the PRV is set to crack open at 70 PSI. How could the pump be in pressure relief at 800 PSI with hot oil. A flow of 4 GPM isn't enough oil flow to create 70+ PSI on the oiling system/pump output to make the PRV crack open. The curves in that...

Seems that it's pretty easy to ingrain misconceptions with YouTube videos. Some are decent with some good info, others are way off in the weeds. Reading comments on YT is sometimes more entertaining than the video itself. 😄

Have you ever seen the efficiency vs micron size rating or the flow vs dP curve for the filters you use? How do you know they with flow with relatively low dP? Every oil filter has more dP with cold thick oil, especially at high RPM. Keep the RPM down until the oil warms up. If a filter doesn't...

Both things can happen. The media can be inefficient due to large pore size, plus particles already caught in the media can be dislodged from the media and flow out of the media as the dP increases across the media. No filter retains every single particle it catches. Some of the already...

Ascent's ISO testing showed all the filters he tested lost efficiency as they loaded up - some worst than others. It's a pretty typical phenomena on oil filters. The ISO 4548-12 efficiency rating is the average of the new vs highly loaded filter. So if an oil filter has a low ISO efficiency...

ISO efficiency test data shows otherwise (see the Ascent testing thread post HERE). As an oil filter loads up and the dP increases, the already captured particles can slough off and go down stream, which makes the filter less efficient. Air filters get more efficient with loading, but oil...

You talking about the crank and connecting rod bearings? If it has roller bearings on the crankshaft, it most likely had journal bearings on the rods.

I haven't seen SuperTech MPs here for months. They use to have spots and price tags on the shelf for them, but that's now gone too.

Depends on if any media tore off the ragged edges. Some fibers probably went into the oiling system, but no large chunks otherwise you'd see a chunk missing.

Wasn't even that big of a gap, and the pleat V isn't very wide either. Must have some pretty weak & brittle media.

Most buyer's at Walmart probably saw no real difference between the ST and MP series, so couldn't justify the cost difference.

Apparently, everyone has their own opinion of the definition, regardless of how it's typically defined. 😄

The flow restriction in a running engine isn't fixed, as I explained about how journal bearings work and act like mini savaging pumps on the pressurized oil supply from the pump. That's why the RPM vs OP curve rolls over as RPM keeps increasing. If the oiling system really was a fixed flow...

+1 ... reusing an inefficient oil filter over multiple OCIs isn't the best idea. If people leave a filter on for multiple OCIs, use one that's high efficiency and rated for a mileage over the total amount of miles planned to be put on the filter. Inefficient filters are that way mainly because...

Yes, any product that is made for and distributed to places like quick lube businesses, etc. and used to conduct their business is a "jobber" product.
