Can someone explain how Valvolene's VR1 meets the (claimed) SN/SM/SL
rating, yet contains the claimed 0.14/0.13 Zinc/Phosphorus? As far as
I can see, any oil rated higher than SL MUST contain less than .12%
Zinc and Phosphorus.
May I offer another solution? Amsoil offers a SG rated 20W50 oil,
which is also rated for diesel engines.
