I’ve been reading lately in these forums about elevated copper levels & Aeroshell products.
Recently, my oil analysis has shown higher copper levels, two out of the last three times with no metal in the filter. I’ve been using Aeroshell 80W+ for at least six years now with no issues until recently. PA28-140/160, O320-E3D.
