This came off my 07 RAV4 with 83k on the engine. The filter was on for 5k (1 year), using Havoline DS 5w20 syn. This OCI I used my $2 per qt Castrol Gold EP 5w20 syn and a Napa Platinum filter. I know the Castrol is overkill for the limited miles I go on this vehicle, but whatever it was cheap so why not use it. I normally use conventional. The filter was a little more wavy than I expected for 5k, so I cut out the media and held up to a bright back light and fortunately had no tears or holes at all, Also didn't have much grit in the can even though the oil was darker than I expected for 5k, must be doing some cleaning from earlier in it's life when I wasn't as on top of the maintenance as I am these days. One odd thing though, it had more than a few small red flakes caught by the media, see pic. These are really small, most look like maybe a quarter to half of a mm, the largest of which I took the pic of. Any idea what that is? I vaguely recall someone else on here asking a similar question but can't remember for sure. Also, does anyone else think that flake looks like a Canadian maple leaf???????
