GM's LS break In Procedures
 

What are the thoughts on GM's procedures? I took these from an LS3 manual, but same principle for LS1?

6. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide
open throttle (WOT) or sustained high RPM accelerations.
7. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
8. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in
gear.
9. Change the oil and filter. Replace the oil per the specification in step 1, and replace the filter with a new PF48
AC Delco oil filter. Inspect the oil and the oil filter for any foreign particles to ensure that the engine is functioning
properly.
10. Drive the next 500 miles (12 to 15 engine hours) under normal conditions. Do not run the engine at its maximum
rated engine speed. Also, do not expose the engine to extended periods of high load.
11. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine
is functioning properly
