Filter looked great to me. No ruffles on bypass. Was replaced with same oil/filter and was the last in my stash. Will be shifting over to Premium Guard XL's next change. Will be posting oil analysis when I get results back from Wix.
I've always blown out my lawn mower filters with compressed air with no issues... foam pre filter won't hurt anything either and will keep the paper element cleaner.
If it was mine I'd be running standard 75w-90 or 80w-90. That's what I have in the front diff/hubs on my Kubota. I'm sure what you found would be fine as well.
Its hard to see, but its the top of the pleat in the 5th picture. To the right of the seam. I moved them around and the next couple tore with minimal pressure as well, but were intact initially.
It doesn't burn a drop in 3k miles.. Always ran Quaker State 10w40 or Havoline. Great motor. It does get a highway run a few times a year and I don't think the extended OCI's are hurting anything.
Pretty much what you would expect from a Purolater that was in service for 3 years, even with low miles, Rough looking with torn pleats. Media was pretty fragile and tore easily. I generally try to change every 2 years, but this time 3 snuck up on me.. Was replaced with a Carquest Premium which...

Only took me 10mo to cut this filter.. Looked good to me and was replaced with a Champ PH48XL. Was on for a year and 6500 miles with Mobil 1 5w-30. Post with oil analysis is here:

I installed mine with a 7/16-14 bolt, nut/washer and a socket. I'd planned to use my harmonic balancer installer, but that kit only had a fine thread 7/16 adapter.
I've got an transmission fluid leak from (I think) my input shaft seal I replaced... So I'll be pulling the transmission again to...
