Kendall Motor Oil re-branding
 

FYI:
For everyone who is running Kendall GT-1 high performance 20w50 in their engines (700sci's, etc.). Kendall has done a re-branding with their products.

Their GT-1 High Performance in the silver bottle is now in a red bottle and re-named GT-1 Competition oil.

I talked to Jay with tech support at Phillips 66 in Houston and it is the same formulation. Both have 1200ppm zinc. Both API service SN.
