Napa Gold 1307 cut open; 150 hours on Kubota

[dnewton3]

NG 1307 (Wix 51307). Date code from 6 years ago.

This was on my Kubota L3430 for nearly 150 hours; 5+ years in year-round, but infrequent use. Paired with VPB semi-syn 10w-30 CJ-4.

My assessment:
- the media was perfectly formed, yet pliable; no rips or tears; well spaced pleats; good adhesion to the end caps
- the base-end bypass was fine (not pictured; it's inside the can)
- the center tube had good punched holes; no flow concerns
- the spring was still strong
I have no qualms whatsoever using a filter for 5 years; nothing to indicate it was at risk of failure.

Another 1307 filter installed of same vintage, with more VPB semi-syn CJ-4 10w-30. (using up the last of my old stock of oil and filters)

back when wix was good, thanks for the photo.

Straight to the point...& one photo op.
Happy to hear you also use some filters that have collected some dust. Although, yours are young in comparison to what I use. You'll hear no whining from me... That WIX filter looks great & nothing to note even after 5 years. Thanks for posting your Kubota filter. You plan to run it another 150 hours or?

You still had the box for a filter put in service 5 years ago? Or was that the replacement?

As mentioned, back when Wix meant something.

Just how many years can a well-kept, unused oil filter be stored before use?

 

[dnewton3]

The box is from the "new" filter just installed.
Yes; probably run another 150 hours or so on this OCI.
I bought those filters from fleetfilter.com, many years back. Stored in a barn; seems perfectly adequate. No rust issues from storage.

So 5 years OCI? You normally go by hours of use? or time?

What Kubota do you have?

 

[dnewton3]

Yes - 5 years and a few months. I typically go by hours. The calendar means zilch to me.

I've run long duration UOAs on my Kubotas and my old Duramax, and realized that these " ... or one year, whichever comes first" policies are just a corporate way of limiting their liability and in no way represent any sane, logical view of the capability of the product (oil or filter). I've cut open many filters which were 3,4,5 and even 6 years old and realized that the age and use are not dictated by the calendar. I even used a fuel filter on my Kubota for 10 years! And when I changed it out, the media was still pliable and yet firm and every bit as capable as the new one which replaced it.

As stated in the OP, it's a Kubota L3430; at my home. I also have an L3830; at my small farm. Both are excellent units and have been 100% trouble free. Both get OCIs around 100-200 hours on the engine, and 300-400 hours on the hydraulic systems. I do the OCIs when my time allows and I don't worry if I overrun the planned OCI by a few hours. I've seen no evidence that it matters that much. I realize that's heresy to the BITOG faithful; they have a compulsion to OCI. But the reality is that it's not THAT mission critical.
