My mechanic has asked me to warm my 07 5.7L engines up at 1000 rpm until they reach operating temperature. Not sure if anyone else has heard this recommendation but I thought I would pass it along. I am not sure on the why, or if this is common knowledge, he made it sound like this was a recently new (last 3 or 4 years?) recommendation from MerCruiser.
