Hey, the case was FREE & the car takes 10.5qts./oil change....Every bit helps, when plausible!

Well no response from Roush thus far!

Thanks all for the responses. I emailed Roush to see. I did correspond with aomeone w/ the last name Roush before I got the oil (I won a free case at an HPDE event in a raffle) & he said it was ok to use in my car...Just want to be double sure! Ron

Does anyone know if Rousch synthetic 5w30 motor oil is ok to use in an 09Z06 Corvette? I hear the oil has to meet GM4718 specs.to use in my car. Does anyone know if this oil does meet that GM spec, or how to go about finding this answer out???? I searched on line but came up empty. Thanks! Ron
