I've taken a look at literally every filter offered for the Gm ecotec engine.
In my opinion, just looking at them visually, the only "very well designed" filter is the OEM filter made by Hengst.
The rest of them are pretty much the exact same design, with is different than the oem, has less pleats, and ends up crushed after 4k miles.
Sure all of them will "work", but I like how the oem filter holds up.
I have used (in recent memory) Fram, Supertech, Purolator, STP, and they have all come out crushed slightly.
Now we get to the question that is a filter being crushed slightly a problem?
I have no idea on that one.
The OEM filter looks fine after 4k miles.
Furthermore, using a non OEM oil filter sometimes causes a TAPPING noise on startup of a cold engine, that I do not hear with the OEM filter.
I have two cars with ecotec engines, a Saturn, and a Pontiac. The pontiac does not care what filter I put in it, it does not tap ever. The saturn will tap with a non OEM filter when it is very cold outside. I literally switched it to an OEM filter, and the next morning it didn't make a sound.
