People who send there oil in to be tested are pinheads. The only people that have any reason to do that are people with built engines. The only way to get real results is to get it tested every oil change over a long period of time, that way you can compare results to see what metals are appearing...waste of money in my opinion.
OEM coolant will still eat plastic.
