Best High Zinc Oil

What oil or oil additives do you guys like to run in engines with a solid lifter cam that need a high zinc ppm, im running vr1 now, i also run castrol and add lucas break in addative.


There is one weight of Mobil1 Synthetic recommended for flat tappet engines: 15w50. It contains 1300ppm of zinc and of phosphorus.

This is not cheap ($8.50/qt), but it might be easier to find at the local store than Joe Gibbs, or Brad Penn.
