I picked up my car in San Diego with 4 miles on the odo and took Mazda at their word regarding minimal engine break-in. Drove 565 miles home on Hwy 99 staying out of cruise control, varying my speed from 60-75 with short passing bursts to 80. The engine only turns around 2000-2500 rpm in sixth at these speeds, so how much abuse could there be?
