Here's a VOA for Valvoline VR1 from 2016.
https://bobistheoilguy.com/forums/ub...pics/4177567/1 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.
