Anyone know what the Phosphorus/ZDDP level is for Amsoil 0W40 Signature Series oil is? Have searched around but have not been able to find any information.

I don't know exactly. It's not over 800-1000ppm. But it's a higher Ca extended drain oil and is different than the 0W-40 Euro oil just mentioned.
