Comparing this M1 filter to two other filters for the same application (Purolator PureOne PL14459, and Bosch 3312) reveals the M1 filter to be of much stouter construction. Both the baseplate and canister wall of the M1 filter is thicker than the other two filters. The baseplate center hole (.41 square inch area oil exit hole) actually has an extra thread (4 threads for the M1 filter, compared to 3 threads for the other two filters) because of the thicker steel used.

The thicker baseplate of the M1 filter has only 5 oil entry holes (1 .3125" diameter hole and 4 .25" diameter holes) compared to 8 total oil entry oils on the other two filters (all 8 holes .2266" in diameter). This gives the M1 filter 0.27 square inches of oil entry area, 16% less than the 0.32 square inches for the other two filters. Whether this slightly less oil entry capacity for the M1 makes a difference in actual oil flow, I don't know. However the three less holes in the baseplate definitely gives the M1 an advantage in baseplate strength, with fewer holes weakening the structure of the baseplate.

Using a kitchen scale reveals the following filter weights: 255 grams for the Bosch 3312, 267 grams for the Purolator PureOne PL14459, and 289 grams for the M1-104. The weight difference between the Purolator and Bosch filters is probably due to the thick, textured exterior paint used on the Purolator filter. The Bosch and Mobil 1 filters use a thin layer of normal black paint. All three filters use similar perforated metal tubes in the center, with a slightly differently constructed bypass valve on the M1 filter. All three filters claim 99.9% filtering efficiency, with only the Purolator and M1 filters claiming extra dirt holding capacity (useful for longer filter life).

Only the M1 filter has a claim of extra filter strength with the claim "Heavy duty filter canister: withstands 9x the normal vehicle oil system operating pressure". I believe this, as the thicker steel construction of the M1 filter makes for a much stronger filter canister.

From what i can tell the K&N filter and this look the same. When used with extend M1 oil, it will go for 15,000 miles or a year. Its 2012, we shouldn't have to change oil every 3,000 miles like we did in the 60's. I've used this for a few years, seems to do the job.

Honest reviews on Mobil 1 M1-104 Extended Performance Oil Filter

Great product at a decent price. They came in a typical Amazon box with bubble wrap, plus the items were in their original boxes. Mobil makes good items and the quality is definitely a step up from the big 4-letter oil filter company.

I always use Mobil1 synthetic oil (0W-40) on my sedans and change the oil every 10,000 miles. This is the Filter to match the oil. The interior is the same as the K&N one... and cheaper!
