I got about 20 bottles of Penzoil 5w30 Platinum from when I had my Cobra...I sold the Cobra and now drive a SHO V6 and want to use this oil...just dont know if there is something I need to do before swiching over...?? I dont really want to do the RX thing again...so I am looking to see an option ...otherwise I need to get rid of this oil...maybe my parts guy will trade me or something...
