I am currently running German Castrol 0W30 in my Heads/cam LS1. I have heard that thin oil and nitrous do not mix very well.

My short block has 140k miles (cylinders looked good, new oil pump and T chain)

Should I upgrade to a thicker oil for nitrous use or will I be ok with the German Castrol 0W30?

Thanks

I would like to know this as well!

I have been using Synthetic Mobil1 15-50 for 6 years with no issues.

Doesn't really matter that the motor sees nitrous IMO. Use the correct weight oil for said bearing clearances in your motor. FWIW, I ran dino castrol 10w40 for the first 1500 miles & ~15 passes on my motor and then swapped to GC 0w30 right before I put it away for winter.
