Can Oil Come Off Our Filters? High Airflow Testing&Engine Air Filter Dynamics

 

Thanks for posting the links you referenced. Did you watch them?

MAF Mystery Part 3 of 4 What does it take to foul a MAF is what you referred to, I think. At 0:31minutes, after submerging in oil "voltage readings were a little awkward" but returned to normal after several cycles (not defined) with no further dunkings.

Their conclusion offered in Part 1 Intro and Test Results: "we have discovered no oil will come off of a filter under any normal operating conditions." (6:52). They did not describe what would happen if excessive oil were applied. They attempt to simulate normal operating conditions in part 2 of 4, but lack in methodology. Their measurements were on a single vehicle (chevy silverado) measuring airspeed anywhere between 1MPH and 12MPH (at an arbitrary location on the filter), and simulating this in a lab measuring cubic feet per minute (CFM). No attempt was made to correlate the two.

The videos were well produced. They did no field testing. They show coating with K&N oil does corrupt MAF readings but these return to normal after removing the source of the oil.

If it were me, I would schedule a test where several different types of cars have oil over-applied to the filters. Drive normally for 2 weeks. Test the MAFs for function and contamination. Repeat as necessary to quantify over-oiling.

Notes

 

But we are not you thank god. But feel free to do it on your own. I knew even before I posted you would find something, anything, to disagree with.

 

I'm disagreeing with you.

Not only did it have problems, it was never "placed back on the vehicle and started."
