^ After the first drain, car #1 drain plug came out stripped (which had a copper seal from dealer). Car #2 came out ok. Chalk it up to probably over tightened the Titek aluminum drain plug on car #1. The oil pan is steel and when you match it up with an aluminum drain plug it's bound to wear out after a few oil drains.
I did some research and picked up a steel magnetic drain plug that will withstand much higher temps than an aluminum drain plug, plus it pulls more iron from the oil versus aluminum. It was twice the cost as aluminum. I left the aluminum in car #2 and will obseve each type of drain plug on next oil change and see which has more iron on the plug and inspect the threads on the Titek aluminum plug for wear.
