Thanks for the input everyone, M1 15w-50 it is.

Just like my old Camaro I plan on doing a UOA every ~3,000 miles.

In my case (2016 Camaro SS which has the same engine as you Corvette) GM. Recommend Dexos2 0W40 or 5W40 for track events. I want to...
Thanks for the replies everyone.

My concern (and why I'm posting here) is that the cold weight of a 15w or in the case of VR1, 20w, seems like a lot for something that is sometimes driven on...
Love this forum, everyone is very helpful and also help solidify my oil selection on my last track toy / weekend car, which was a 2013 ZL1.
I currently have a 2016 C7 Z51 Corvette with a dry sump that holds 9.8 qt of oil. The car is only driven on the road course, autocross and then on the...

Another question for you oil guru's. My second analysis had 2,730 miles on the oil where as this most recent one had 5,029 miles (and twice as many track events). In the comment section Blackstone mentions that normally aluminum shouldn't increase with longer oil runs. But what about iron? Same...

People have done many different things to aid in cooling the blower...

I appreciate all of the time everyone is taking to post in here with suggestions and actually have detailed posts explaining their suggestions. Very useful! I'm a car guy, not an oil guy so I'm very open to learning as much as possible in regards to protecting my engine from the torture I put it...

If you search for Amazon.com 0w-40, notice the M1 0w-40 is a bargain in the 5-quart jug, similar to what walmart sells it for. This is the bargain for a...
