Not so bad, not so good.

This is the full synthetic Fram filter with the metal screen backing for the filter media. $10 at Walmart.

According to the ISO 4406 Cleanliness code your ISO code should read: ISO Code 17/15 not 17/13.

A cleanliness "goal" for a diesel engine is "about" 16/14 (per newer standard).

So, for an expensive filter.....??? Make your own conclusions. Maybe the sample was tainted? How was your sample technique? Keep in mind I have yet to do a used oil analysis sample, but I've read "how to's" in taking a clean sample.

 

[SWHeat]

My error. I was reading 5 micron/10 micron instead of 5 micron/15 micron so the 17/13 IS correct (albeit on the edge of the 13 range..amost 14). Sorry about that.

I wonder if there is any data re: and ISO cleanliness "goal" for a gasoline engine. Filter guy?

 

[Filter guy]

Nope..

You can email an OEM and ask if they have a recommended cleanliness level.

It would be interesting to see their responce.

How was your sample technique?

I am carefull to get a good sample. Here is how it went.

-Drove car around for about 20min to get it warmed up.
-Waited about 20-30 min for it to cool down a bit.
-Removed drain plug and let it drain for a few seconds.
-Put sample container in stream to collect sample.
-Filled to brim, it overflowed, hot oil burning my hands, screwed cap on, dropped bottle and quickly grabbed rag to wipe off hot oil.
-Wiped oil off of exterior of bottle.
-Placed in mailing container and sent it to Blackstone.

Thanks Winston. Looks like good "clean technique" to me. That is, except for the "hot oil burning my hands" part. OUCH!

Good gracious - put some leather gloves on, and then put plastic gloves over them.
