Bonneville America Forums Forums Technical Forums General Tech Glue melting in oil filter

Sorry if I gave the inference that the Purolator and Pure 1 filters were as bad as a Fram oil filter, because they are not. In the test results of oil filters that I have seen both the Purolator and Pure 1 filters are in the middle of the pack with Fram being near the bottom. The only filters that I have seen tested with a better rating than the Purolator or Pure 1 filters is Hastings, Hard Driver, Mobil 1 and Amsoil.

Where the Purolator and Pure 1 filters fall short is in the SAE HS806 Filter Capacity test. Both tested out at more than 35% below the best filter. The Pure 1 filter was very close to the best filter in the SAE HS806 Filtration Efficiency test.

So if you are going to pick between the Purolator or Pure 1 filters go with the Pure 1.
