Flow vs efficiency

[finmile]

Amazon gives the same 28 grams at least for the following M1-xxx oil filters:
M1-104 (28.2 in^3)
M1-108 (16.3 in^3)
M1-110 (21.5 in^3)
M1-209 (33.1 in^3)
M1-210 (45.6 in^3)

This can't be right...

The smallest M1-xxx filter is M1-108 with 16.3 in^3 displacement and the biggest is M1-601 with 126.2 in^3 displacement. And they both are supposed to hold 28 grams of dust.

Apparently I need a better source of information

Most of the boxes that state efficiency say the filter size that was tested and it usually isn't the filter you are looking at. My guess is the capacity is the same thing.

Steveh - thanks for the ACDelco link. This is very informative.

Motorking - thanks for representing yourself, your company and product by posting and dialoging with BITOG members. It is informative and helps me with my purchasing choices. I would be interested in knowing how the Fram Core compares with the other Fram filters in terms of construction, efficiency, capacity and use guidelines.

I have learned to not trust technical details from Amazon.

Thanks

The dust holding capacity seems to be directly proportional to the filtration area. Also, the displacement of the oil filter has some correlation with the dust holding capacity.

- W67/1: Displacement 13.6 in^3, filtration area 75.3 in^2, dust holding capacity 4 grams
- W610/3: Displacement 18.8 in^3, filtration area 125.9 in^2, dust holding capacity 7 grams

Ratio for displacement = 1.38
Ratio for filtration area = 1.67
Ratio for dust holding capacity = 1.75

Does anyone know which M1-xxx oil filter has the 28 gram capacity? I could then extrapolate the capacity for M1-108.

It might help to look at holding capacity, like with an old round air cleaner. The part of the round filter right by the intake tubing would be bombarded with dirt, but the rest of the filter was quite clean.


So, even if the filter 'has' the capability- it probably isnt perfect enough to distribute it even across all the pleats.

^^^ An oil filters should have a pretty even distribution of debris around the entire media assembly because of the evenly spaced base inlet holes and the evenly flowing center tube.
