Had something similar with royal purpleI put Lucas in a hemi once and it made the engine noisy.I drained it all out and never used it again.An oilman told me that motor oils contain stabilizers.And adding more to their balanced mix just wasn't necessary,and only messed up the proper additive package balance.And because of each brand having different detergents,to not mix brands of oil in the same engine.To get the best benefit.I can agree with this, If anyone doesn't,it matters not to me.I do me,you do you!
