I have a new to me 2013 Corvette z06 with the ls7 motor. I must suck at searching as I cannot find a thread about it. The motor has been aroung since 2006/7 and is in wide use. I used both Redline and Pennzoil synthetics in my 2004 z06 ls6 motor. Thanks if you can help. Only full synthetics for my performance cars. This will be a street & track car and I won't be changing oil for track.
