Everyone around here uses VR-1 too.It really is the most economical and best solution I think.

Not everyone Rick....I use Rotella and I had the foresight to stock up on the old Rotella with the API rating of CI-4. The new Rotella has a new API rating of CJ-4 which I understand has a lower level of zinc but still has more zinc than conventional moror oil. When my supply of Rotella runs dry(which should take several years) I too will probably switch to the Valvoline VR1.
