No details at all. Not sure which lab. I'm not sure why they even went outside other than to stem the usual critics. I assume it was run up and down with loads.
I just got an order of AMSOIL Signature Series 0w40. Still the older formula. The new formula has lettering that is level. The older formula is at an angle on the front. I think my engine will survive on the old formula.
@Pablo Is the new product data bulletin on the updated Amsoil Signature Series released yet? Wondering if the specs will be similar to the current formulas.
