As an example, Lycoming aircraft engines specifically say that running at low power during the initial break in will lead to a glazing of the cylinders, poor ring seal and thus high oil consumption. Once you do that, the only way to fix it to take the engine apart and hone the cylinder walls. If anyone cares about proper engine operation, it's aviators. Basically they recommend proper warming up, use the proper oil specific to break in, and then full power takeoffs and climbs and fairly high power cruise initially. What I would like to know is what would be ideal in terms of oil and engine accelerations during break in of an ST. Not saying abuse it, but running it up towards redline and then decelerating periodically may be beneficial. Any auto experts out there who have actual experience with new engines and different break in procedures?
