Any Valvoline users running solid flat tappets?

If you are, you might want to re-think that choice.

I just got my Valvoline 20w-50 tested. One test for virgin oil, one test for used oil (about 300 miles on it). In both cases, the Zinc and Phosphorous numbers are way too low.

The results are attached. That's to Patrick for suggesting I get it tested. I am switching to Brad Penn 20w-50.

Edit: PM me with your email if you want the PDF version of this report. I couldn't get it to upload a PDF.
