I sent out a VOA of Motul 8100 ecolite 0w-20 and it came back with high wear metals and severity 4. I figure from the holding tank. Should I as for a retest?
No on my end it came from (probably the bottom) of a sealed plastic 5L jug after I had filled a car so it should have been mixed up. I assume that would have come from the storage container at the factory....
