Carquest, Supertech or Pentius for Kubota tractor?

[Elkins45]

With the Carquest closeouts at Rock Auto I can get some of their Carquest premium filters for <$4 (before shipping) or I can get the Pentius PLB16 from Amazon or Supertech ST16 from Walmart at essentially the same price.

Are the Carquest sufficiently higher quality to justify spending the extra $15 to ship a dozen?

With Carquest, you are at least (at the moment) getting some assurance of quality which is a kind of a rare thing the past few years.

Pretty sure those closeout Carquest Premium at Rock Auto are the older discontinued models. .. I could be wrong but why would they put the newer better quality filters on closeout at Rock Auto?


Maybe you would get lucky but I bet they are the older discontinued models and if you get them make sure to check if the louvers are open.

it’s from all the AAP’s that closed down recently. got tons of CQ premium parts from them recently.

Get a new fresh higher end filter, then in two years or whatever the interval , buy another one. In hindsight, I wish I had heeded this. What does one do with a case of filters that will last twelve years unless they are being changed very often.

I don't run OEM filters on anything... Except my Kubota. The OEM Filter is less than $15 and built like a tank. I change every 2 years and they've looked great when I cut them.

Filter was on my L4701 for 2 years/100 hrs. 15w-40 Delvac. Same went back in. Nice filters IMO. Nitrile anti-drainback valve was a little stiff, but seemed to still be doing its job.

Also I don't think the 16's are a true cross reference to the Kubota filter. Fram list this one as correct:

https://www.fram.com/fram-extra-guard-oil-filter-spin-on-ph7328

and it has a 22lb bypass vs 12lb on the PH16

The Carquest 85311 list bypass pressure as 14 psi.

Baldwin B7152 would be a correct filter and has 20lb bypass.

Fram lists the PH16 for my L3800 when I use their parts search, but when I search for a cross for HH164-32430 I get the 7328 you mention.

There’s a Wix 51307 on it now.

Yeah that one has bypass of 8-11 psi as well.. Be curious what the oem is, and if the oil pressure in the Kubota would cause one of these to run in bypass more than it should.

Auto Zone has S7328 for $5.99…

Rock Auto has PH7328 for $5.50, plus shipping…

I use Ph8a / Wix 51515 equivalent instead of Ph16, longer, same base, and bypass…

Wix 51773 is the supersized version of the Ph8a…

Wix specifies the 51307. What's your source that the HH164-32430 correct bypass pressure is 20-22 pounds? I did some Googling and the only thing I found with a bypass spec was a webpage listing it at 2.5 bar. 1 bar =14.504 PSI so that's around 35 psi.
