Here is a new fram ultra used for 180 hours on my gen 3 coyote truck. It was changed earlier then usual but I wanted to see how it held up. I may have given it a bit of a twist as I used a wrench to remove it which indented it some.
It got a new fram ultra as well. The new style again.What oil filter did you replace it with? I will let the oil filter experts here comment about your oil filter.
Thanks for the Pics!
What causes the wavy media ?
I've heard it can be caused by moisture absolution in the media due to more condensation in the oil during colder/winter months and short trips.What causes the wavy media ?
That's good to hear.Fairly strong media. Much stronger then the motorcraft ones I have cut.
Once the center media, center tube and end caps are all assembled, there is no "size squashing" of the assembly.I bet the glued filter + endcaps assembly goes through a sizing machine which squashes down to a proscribed height and buckles the media.
Kinda my guess too. Maybe once it gets wet it expands?A pleat that is made straight, then is curved after use has to be stretched because it’s longer. That can’t be so wonderful for “efficiency.” Can it?
On one hand I am happy to see a First Branded Ultra hold up well over a standard FCI but on the other hand I would like to see more positive results before getting back into buying them. My current filter stash is pretty nice so it may be a while.
