Just stick to what you have been using and you will be fine...

Looks like the Purolator Boss would be a PBL25288. The MicroGard Select is a MSL51522. I'm not as familiar with the construction of these.

Both very good filters

Its 46 micron @ 99% as others posted

Go The the Advance Auto Parts website and see what they have posted. Carquest Premium Blue is 99.5% @ 20 microns. MicroGard Select 51522 is 99% @ 25 microns.

Is this the same blsnelling on various chainsaw related forums over the years?

That's me I've been an oil/filter guy for years, lol.

Basically, what I'm looking for is a 3675/51522 equivalent 4" tall filter with a mesh backed media and at least 99% @ 25 microns efficiency.

Purolator is the only one willing to share an official specification sheet. The Carquest Premiums & Oreilly's Microgards are really well built filters & will do everything you need them to except efficiency spec since that's not known.

Contrary to their own documentation, the FE9837 DOES have an ADBV! The proof's in the pudding.

I'll be honest, that Carquest Premium Blue looks like a fantastic choice. The only feature missing is the wire backed media. Can beat the value!

Looking at their website pictures it shows Microgard with a silicon Oring gasket while the Carquest does not. Go to the store to actually look at these filters before making your decision. Good to know if the Microgard & Carquest are actually different.

can confirm that new stock has silicone O-rings. that is my go-to filter to put on all of the LS swap projects we do. old stock i’ve seen is still premium guard just without the silicone O-ring.

Which brings me to the next point I was going to make to OP since they're the same (I assumed the same as well) but thanks for actual confirmation.

May have to "click to expand" for you to see my bold.

See how @BrendanC confirmed most likely the exact same PG built filter but one claims one efficiency while the other higher efficiency. Obviously, it's a shot in the dark for what it actually is & until you see a spec sheet for that individual filter you'll never know for certain. However, as I & others have mentioned here those filters have a very good build quality. IMO deserves to be run as most other filters for OEM Drain intervals or slightly longer (10k rating).

I can confirm. This is for a different application, but I just bought it yesterday.

Glad you were able to figure that out. Same filter with 2 different claimed ratings...no surprise from me.

the filter you bought does not cross to a 3675. that filter is a 10575 equivalent.

ahh, i must have missed that. sorry!

About the FE9837...what is the purpose of a ADBV if the filter installs vertically anyway? Why would one be needed for my application?

The ADBV still keeps the oil in the galleries above the filter from draining down.

It doesn't need wire backing because it's not full synthetic media.
