Yes, I know the viscosity and ZDDP levels are unnecessarily high. I have dollar quarts of VR1 to use up, so I'll continue to use the Bandito Blend until they're gone. I have receipts for plenty of NAPA 0w-20. No harm done.
Refilled with the same plus a can of MoS2 that I had sitting around.
Cheers.
