Well my Camry has been having some sparkly drain pans when I change the oil. I bought the car at 185k miles in late November and changed the oil with 5w30 Mobil Super HM for 2,800 miles. That first change with unknown oil I paid no attention to the drain pan, can't remember what it looked like. 2,800 miles on the Mobil Super HM gave me the what is in the first picture in the bottom of the drain pan. I then changed the oil with Pennzoil Ultra 5w30 and ran for 4,500 miles, which the results of the drain pan is what the second picture shows. That time I cut open the oil filter (always previously used Wix) and it looked great. The 3rd and 4th pictures are of the oil filter, it looks shiny in the first picture of the oil filter because of the camera angle with the sunlight, there was not any shavings or glitter looking stuff in it.
No this isn't a joke (as others have thought in my previous post about it) and the car actually runs well.
I've decided to do a UOA on this oil to see whether or not I should keep this car or not.
Other thought it might be excess from an additive the previous owner COULD have used, I bought it with an oil leak. Valve cover gasket was leaking (I changed, looked pretty decent under there), leaky oil pan gasket which I've been too lazy to change, and the oil filter was a little loose. Others thought maybe he put something in there to try to stop the leak but I have no proof of that and I don't know if that would still be coming out in oil changed. I don't know.
I have 1,700 on this OCI and would like to sample it now so that if it reads with really high metal levels I can get rid of this car as soon as possible.
My question is, would 1,700 be adequate for a UOA? I believe Blackstone recommends at least 500-1,000 miles for an accurate UOA. I have the kit ready to go, and think it should be able to show.
So what do you guys think? Run a little longer or dump it now?
