NEW M1-103A filter CUT OPEN

Thanks Bullwinkle. I am not sold on M1 filters either

Could you explain your reasons and what is the difference between the A filters and the older ones?

 

[bullwinkle]

The "A" suffix filters have been made by a different manufacturer, no longer Champion Labs, and the efficiency rating is ambiguous, whoever makes them now. Pleat spacing could be better, too, although that's a minor complaint. Not sure if the COO is S. Korea, or possibly China?

Nice pre-mortem. Thanks for sharing. Im with you on the WIX for my toyotas.

COO is USA, and they are still made by Champ

The first pic in the OP says "Product of USA"

The other pics show the same Champ construction, same blue bypass valve

I like M1 oil filters because they use the base plate type by-pass.

Uh, you mean base plate ADBV. Bypass valve is in dome end

Isn't that a base plate type by-pass valve in this pic?

The Mobil 1 M1-301 and M1-209 oil filters used base end bypass as well as seperate base end ADBV. Not sure if that continued with their "A" suffix successors.

Major differences I see on the newer "A" suffix M1 oil filters vs their most recent predecessors are:

1. New filters are rated and warranteed for 20K miles max, prior filters were rated and warranteed for 15K miles max.

2. New filters have advertised efficiency of 99% @ 30 microns, prior filters had advertised efficiency of 99.6% @ 20 microns.

3. There has been more than one example of new filters with uneven pleat spacing, C&P's of prior filters showed consistent pleat spacing.

Things I see as kept the same:

1. M1 oil filters are made by Champion Laboratoties in the USA for spin-on canister filters (I have no knowledge on cartridge applications).

2. M1 spin-on canister oil filters do not use combo valves. Silicone ADBV is standard.

Thank you GT. I learned something new today.

+1, it would make sense for those "scoops" to act like a mechanical limit stop on the leaf spring so the 4 legs on the blue button bypass aren't in contact with or depressed by the inner dome surface of the can when the leaf spring is compressed.


Good observation. I pressed the spring down so the scoops touched the end cap, and there is only a small gap above the bypass valve prongs, maybe .5mm. I was trying to figure out why the scoops are off center and I think it helps stabilize the bypass spring so it won't rock and leak. Very simple things sometimes have a lot behind them.

Correction of prior typo in red

That is one big dude … I ordered one for my remote transmission mount … then realized I’d have to cut the grill … XG16 fits better … we used it one an old 3.5L Pentastar …
