Changed oil today. I got some Dimple magnetic drain plugs and the fellow at Dimple asked me to take pics of the material they picked up so I thought I'd pass them along. Quite surprised at the material on the oil cooler drain plug. Didn't think there would be anything on it but it was nearly as bad as the oil pan plug. Because I am so bored, I tracked the oil from the catch can, oil cooler and crankcase separately and it breaks down as follows; oil drained from crankcase 97.05%, oil cooler 2.715% and the catch can 0.235%. The catch can didn't have much but I don't want any going through the intake (At 20,000 miles I had an oil plugged intercooler on a F150 Lightning I once owned). The oil was 6 months old with 800 miles on it (THANK YOU SRT!!!!). Now the only thing I have to decide is if I recycle the oil or use it to change the oil in my Cadillac!
