Hi everyone, I recently did a HPDE event. I changed the oil and I found what looks like a lot of bearing material in the oil. Admittedly, I don't really know what is a lot and what is normal so I figured I'd ask the forum. I have attached some pictures. Ambient temperature at the event was about 100 degrees F. My Mustang is equipped with a Boss 302 radiator and a Setrab 925 oil cooler. The oil I was running at the time was Schaeffer 5w50 race oil which came highly recommended from a local performance shop. I'm thinking the oil just got too hot and couldn't adequately protect the engine. The engine wasn't knocking with the 5w50 in it but I don't know what would happen with if I went back to 5w20. Any input you have would be appreciated. Thanks for reading.
