Hey guys. Truck is a 2014 tundra with the 5.7, 240k miles. I switched over to HPL 5w30 HDEO from Schaeffers 5w30 supreme 9000. I put 7883 miles on the oil before I changed the filter (I didn't want to go a full 10k as usual based on what I've read and seen on this forum and the carbon build up in the filters), I've been letting it dry out a few days. Upon inspection I didn't find the carbon build up others have posted (I'm assuming this is from the the 5k OCI Toyota oil the PO used and the Schaeffers 10k OCI I used since then, bought the truck with 172k), but have found 60+ metal flakes in the oil filter. They're not magnetic, so I'm assuming they're aluminum. All the oil filters I cut open previously never had any metal flakes. And I've cut open every filter for every oil change I've done on this truck. My driving habits haven't changed, and I have UOAs from previous oil changes and everything looks great. I did get a sample of oil when I changed my filter (fumoto valve on the oil pan), ill be sending it off this week. What in world is happening? Is this a bad batch of oil? Mechanical anomaly? These engines can run for many hundreds of thousands of miles, so I wasn't expecting to see this from what was a healthy engine last UOA. The only thing that changed was the oil used. I'm not placing blame on the HPL oil, it's just the only thing I can think of that has changed.
