The OP is in Los Angeles, so the car will likely not be operated under 30 degrees. I seriously doubt that a 5W40 or 0W40 oil will be any kind of a problem for year-round use. I am in San Diego and have been running this slightly heavier oil full time in my LS 1LE. I mostly follow the oil change schedule recommended by the car, and my Blackstone oil analysis results have been excellent.

I would think if the engineers at GM wanted non1LE LGX cars to add a quart of oil prior to tracking they would have included it in the manual. I couldn't see how they would miss it in these days of CYA. Will keep an eye on the oil pressure when I hit the track Monday.
