I sent my first analysis off and received this back. It states it's critical but doesn't show any wear metals. This sample was from a new 5L jug of Quaker State Euro 5w40. I put 1.5 jugs into my motor and this was from the 2.5L remaining in the jug. I shook the jug up before sending it in. This oil did not come from the motor of my vehicle. I'm a little confused by what they are are saying as the only ppm numbers are all green.
