Was looking at the PDS sheets for Mag1 Syn blend hm oil and they have changed quite a bit. Moly has went to 40 ppm.,boron to 70 ppm. phos. 640 ppm. zinc to 700 ppm. If this is the same or similar to the ST All Mileage it too will probably change. The takeover of WPP by the Pritzker family is probably why.
