So then why not run 0w20 in the vette. Why read the charts on the temps oil breaks down. Hell why even have oil weight or ratings or synthetic? Sorry but you are clueless if you believe a 1500 sees more stress towing then a corvette on track day. Have you even seen the tune even in just the trans for even tow mode?Or the data from the two? Gm have raced the corvettes and built them for abuse and still on track day many issues arise. Take to a top tier performance build and ask if oil matters or if a stock l83,l86,lt1,lt4,ect.... in different platforms,tunes, and trans matter if he says not at all it's the same then you are right. I will run it buy the head race development guy on tuesday just for good laugh. [emoji38] Sent from my SM-N960U using Tapatalk
