Actually…..the oil pump sucks it from the oil pan and then blows it into the outside of the filter. 😂
The filter is after the pump. 😉
The pump can blow a golf ball thru a garden hose then ;)

I wonder if that was an Autonation dealership? As a former employee, they started their own line of fast moving parts, "Precision Parts" (ie....air filters, cabin filters, oil filters....) and instructed the managers at their dealerships to use "their" filters INSTEAD of the OEM filters (except under OEM warranty). Premium Guard was the supplier of Autonations filters. At least it was when I was there. Garbage. Just as autonation is, IMHO.

Actually, it does matter if it sucks or blows. Liquid can only be sucked up to the point of it's vapor pressure before it cavitates/boils and can't be siphoned any further than the ambient pressure on the supply side.

It's semantics, but you don't really "suck" or draw anything, you create a low pressure and the high pressure on the other side then pushes the fluid.

So to create any sort of real pressure, fluid is "pushed" or driven with a pump rather than drawn.

The filter wouldn't collapse if you were using the typical pressures in drawing it through the assembly. The pressure differential across the filter is what creates the force (in this case inward).

Consider that if the supply pressure spikes to 100 psi, and differential across the filter as it pushes through is only 10 psi, the filter has about 45 square inches of surface area, meaning it's resisting 450 lbs of total force trying to collapse inward and crush it.

It would be an interesting study to determine the conditions that create the most force on the filter.

In the beginning of the oil service interval, the oil has it's maximum viscosity and therefore most resistance to flow across the filter media. However, at the start of the service interval is when the filter is most clean and free of captured particulates and flows best. So as the oil is cut and sheered and contaminated it degrades in viscosity, improving flow, but the filter also "clogs" up further and further with captured gunk. We all know temperature plays a part. It's not good to flog the car until the oil warms to operating temp. So let's assume for a moment we're at typical operating temps.

It would be interesting to determine whether it's right after an oil change, at full temp, redline that creates the most load on the filter. OR is it after the filter is diminished (but so has the oil).
