How many of you re-use your filters atleast once?

The results are in for the third oil change on the same EAO. Everything looks good as far as engine wear metals, the ISO Code read 17/17/14, not as good as the first change (16/15/12), but better than the second one 18/17/15. I see no reason given these results, not to use this filter for multiple oil changes.
 
I reused the factory oil filter on the vibe. it was a bear to get off, so I just drained the factory fill. put in kendal synblend, then changed the oil and filter again at 3500 miles
 
Yeah, me too!

ISO code 4406 is a three part code for oil cleanliness. The first number refers to the range of particle sizes larger than 4 microns, the second # larger than 6 microns and the last larger than 14 microns. There is a chart that you can look up to see what each ISO number represents. The values are based on a one milliliter sample. The EAO filter will actually make the oil cleaner than what is initially poured in.
 
I just put in my 3rd OCI of ~5K on my EAO. It's nice not having to mess with the filter every time. I plan to get at least the full 25K out of it.
 
If I am changing the oil the filter gets changed at the same time. I would never keep using it for 2, 3, + OC's.

Wow I am suprised at the number of people who don't change the filter at every OC. Not being a jerk or anything. It is your engine. Just can't believe it.
 
What's so amazing? Filters fatigue based on the amount of material that passes through them. If you're above a certain amount of mileage, you're producing way less filterable material per mile. Short trip type ...lower annual mileage types ..every oil change. Higher mileage types ...

Look at your OLM engines. Some go 5k on one oil change ..others go up to 15k before triggering the change oil thing. They keep the same filter.

That is, you can reason the filter life into that mix. Less fuel saturation/dilution due to fewer warm up cycles ..less combustion byproducts .. less moisture contamination....blablabla.
 
Some vehicles actually call for a filter change on every other oil change service.

I have never owned one of these cars, they are usually luxo euro type cars.

I'll stick with replacing mine every time, thanks.
 
Ditto. What's 2-4 bucks to change the darn thing at 5k-7k miles?

Peace of mind is usually WAY more expensive than that.

The filter is the cheapest part of the OC. Why risk it? As someone else in this thread mentions we all go nuts trying to use only the best oil yet people want to skimp and reuse the filter.

Again, if that is what you want to do go for it. Just surprised me is all. I personally wouldn't dream of it.
 
If you insist on using a Fram filter, by all means, change it every OC. A EAO can be extended for multiple changes due to the high quality construction and it's synthetic media.

This is where you're mistaken. It's not to "skimp". It can easily allow you to get your money's worth out of a $8 filter when you're used to using the $2.25 cheap one.

You'd be hard pressed to justify a M1 or EaO filter over 3k/3m. The numbers just don't work too well (that's if you're looking for ROI). OTOH, if you're doing 12k a year ..and are STILL trapped in the 3k OCI, then you can get the added utility of a finer filter and NOT spend a dime more than the joe who's thinking that he's saving large in his tightwad manner with the $2.24 ST.

See?
 
What I'm looking for is actual facts and you guys probably have all that info from your UOA's. I believe that the filter becomes more efficient the longer it's installed- eventually it gets too restrictive and will bypass so the goal is obviously to change before that point.

So by removing a used filter thats only allowing particles say 5 microns or less to pass, with a new filter thats completely unblocked and allowing particles of 20-30 microns, just makes no sense at all. I'd rather leave in the old filter longer.

I don't think this works with junk filters, since their media might collapse or fall apart, but with name brands like Pureone, Wix, or Amsoil you should have no problems...

Again- I'd love to see uoa's for first, second, third oil changes on the same filter- with particle sizes given.
 
Actual particle sizes were not given from Blackstone. The optional ISO cleanliness code showed that for the first OCI, the oil was very clean. Leaving the filter on and it's "dirty" oil inside, the ISO code for the second OCI showed a bit more contaminents. The third OCI on the same filter, same conditions, showed that the efficiency of the filter was increasing, leaving less contaminents than OCI #2. Neither second or third change equalled the first one. I am going to change the EAO 20 every OC for the next 3, to see how this effects contaminent levels.

Buster had 27K miles on an EAO at one point with an excellent UOA to go along with it so we know they are good for a lot of miles.
