NicaSil cylinders and moly rings do not need (or benefit from) the break-in procedures that old engine technologies required. The rings are seated during the first few revolutions. You cannot wear into the hard cylinder walls, and there is no cross-hatch pattern to wear into. The oil usage here is not really due to burning oil, but to other issues like venting to the airbox. If any oil is pulled past the rings or valve guides, it would be because synthetics cling so well and are so slippery. Unfortunately, dino oils do not provide adequate lubrication, resistance to shearing, superior film strength, and other characteristics that these modern engines need. If the manufacturer, like BMW, says to use a break-in oil (usually dino oil), by all means do so. Those BMW models have conventional cast iron cylinder liners, and require the break-in. If a semi-synthetic is specified, or even a full synthetic, I'd go that route, especially with hardened cylinders. They don't just have an intern dream this stuff up. Their recommendations are based on the materials and methods used, factory tests, and sound engineering. JMHO
