AMSOIL XL7500 UOA showed high level of Potassium (4) and Sodium (11) but no trace of antifreeze was found!
Blackstone thinks it came from oil additive but no oil or gas additive was used. they also think Sodium/Potassium may be the result of high bearing wear! Lead (15) copper (13)
What do you guys think?
