I picked up a few 5 qt. jugs of 0w20 and 5w20 Gold Edge 20K at the AA 'Clearance' last year. I'd never run it anywhere near 20K but I would feel better if I went over my approximately 7500 mile OCI limit using this oil or Mobil1 EP. Former BITOGer Ghokan was very enthusiastic about this Gold Edge. I miss him on this site.
