I have a stroker LT1 that was built using low tension rings. The engine uses about a quart every thousand miles. It gets black pretty quickly, due to fuel I am sure getting past the rings. The compression is fine, 195-200psi, and the engine makes good power, fires right up and plugs are fine. But the oil is Mobil one, 10w30 or 10w40. Either makes no difference to me, but I have been looking into Redline or Royal Purple now. It has a hydraulic roller cam, roller rockers etc so it is a little louder and has the familiar ticking from the lifters. If an oil can quiet this down, great, and reduce oil consumption, even better. Thanks in advance.
