Metal particles in new Supertech 3593A non e-core

[oilyriser]

This filter was purchased a couple of years ago, and stored in the original box. I shook the filter so any loose material would be shaken off, then half filled it with clean gasoline. Then I turned it upside down over a clean container, to drain. I placed a magnet under the container, and took another photo (#2). Finally, I wiped the threads with a piece of tissue. (#3).


1. Filter

2. container of gasoline used to rinse filter, with magnet underneath

3. wiped threads with paper

I wipe off the threads of a filter prior to installation. Regardless of brand I've always found machine oil, as your photo illustrates, left behind.

I've found that on every filter i've ever used. I always wipe the threads and such, too. Btw that's the same filter I use on my car

Now we know why wear metals are highest in the first 3000 miles of operation ...AND the REAL reason the engine manufacturers have promoted the "every other" OCI filter change.

There has to be cost-cutting measures to offer a filter this inexpensively. I've never been to a filter factory, but one look at this filter suggests one of the cost-cutting savings could be the lack of a blow-dryer either after fliter assembly -- or way-back in the production-cutting of the metallic parts.

I would guesstimate that the upper-end priced filters do a better cleanup.

The Mobil 1 filter I looked at also had dirty threads. So did the Pure1. The cleanest threads I've seen were on the low cost Honeywell Defense, and Fram. If these filter companies learned eachother's tricks, we could have the perfect filter.

Maybe I should buy a remote filter mount, just to flush the filters with some gas, using one of those hand powered bulb pumps they have on outboard motors. I'd use gas since it can go into the lawn mower afterwards.

Gary might be right.

p.s. The dirt wiped off the threads in the last photo was after rinsing the filter with gas. The filter was still wet with gas when I took the shot.

I didn't say to wash any parts or completed filters at the factory. We are talking about metal particles here -- not dirt.

Well, there's one way to find out...

 

[ted s]

but goes gas damage the filter media?

 

[Gary Allan]

I dunno

..but it probably puts more fuel in your oil than you would normally over a decent duration. At least it's clean

 

[Auto-Union]

Maybe old oil would be ok to flush out a filter?

 

[mfisher1967]

Let me ask a couple of dumb questions here:

First, will cleaning an oil filter with gasoline hurt the o-ring, filter media, or the adhesive used to secure the filter media to the end caps?

Second, Will residual gasoline in the filter contaminate the oil? Not all components in gasoline evaporate.

 

[rustlerdude]

I would say flush it with clean motor oil.

Vacuum it out? If you vac the center core, that should do it.
