This is my mother-in-law’s Mazda 6 she bought new. Car has 116k miles, been doing 10k mile OCIs on Amsoil SS 0W20 for the last 30k. Filter was an STP S7317XL, FE6607 went back on. Took a sample when I changed it. She drives about 40 min each way to work, mostly hwy and country roads. Looks good to me. Lab is our local CAT dealer.

This is excellent. Low wear rate, no sign of fuel dilution. Seems to be working!
I might try a 30 weight just to see if the wear metal got even lower for curiosity’s sake, but it’s not necessary.

Depending on the starting oxidation of this oil, at 10k it was just getting started. I ran PUP to 17.1k in the same engine; I’d personally expect Amsoil to be able to trounce that. Nice run anyways, thanks for the UOA!
Question on the 6607 filter- why not the FE7317?

The STP was just what I had on the shelf honestly. I will cut it open this weekend hopefully and post it. I was trying to get an FE7317 but my Walmart was out.
They were out when I went to buy the filter, otherwise it would’ve been that.

The STP is a good filter. Maybe not quite as efficient but good quality.
Very nice run!
As I said, at 10k the Amsoil was just starting to stretch its legs. Personally I’d go at least 15k next time and do an in-service sample…. OP may be able to go 20k with no worries.
If OP is concerned about filtration, they could always do a filter swap & top-up at 10k, the 8oz or so in the filter will not skew the UOA at 15k much at all with numbers this good at 10k.

Do we know what the TBN is?
