More ado , discussions and worry about motor oil than what is justified.
Just because it's labelled synthetic doesn't mean it is. Castrol etc is just a super treated mineral oil. Mobile 1, Amsoil, royal Purple and Lubrication engineers is real synthetic.
Synthetic is for extreme heat, extreme cold or extreme pressure.
There is low ash and regular lube oils. Don't mix them up.
