Ring seating has nothing to do with "tight specs".
New (or overhauled) cylinders have a special cross-hatch pattern honed into them for the express purpose of seating new rings. This is true with any new engine, auto motorcycle, boat, lawnmower or airplane.
It is important to avoid constant speed cruising (or long idles), but to "vary your speed".
Best method is frequent, short accelerations from 2500-4500 RPM at 3/4 throttle, immediately followed by foot off the pedal deceleration back to 2500.
This will not only save those liters of oil between changes, but will give you a better performing, longer lasting and more efficient (economical) engine.
Just try to avoid driving for good gas mileage for those first few hundred miles.
If it's an aircraft, you are prohibited by law (Approved Pilots Operating Handbook) to use any economy cruise power settings before rings have seated. |
