Re: Small Block Crate Engine Advice

Ok one last question, I am past the break-in period for the engine and need to do its first oil change.

I was planning on using 15/40 T4 Rotella. Engine is a roller cam (not flat tappet), so I think a good quality oil with no additives would be fine. But should I use a 10/30 instead?

I asked Blueprint this question last week, but - you guessed it - no response from them, just crickets.
