Here's a VOA for Valvoline VR1 from 2016. These values for zinc and phosphorous, if accurate, are too low for solid flat tappet cams. Now, the VR1 data sheet lists the values as higher (0.14/0.13). Most SFT guys nowadays go with either Joe Gibbs or Brad Penn exclusively. I use the latter, and you can order either brand off of Amazon, even if you live in the Arctic Circle.
