Redline 50W Racing, 200 race miles, WC spec SRT-4

[DavidT]

So the oil sheared down from 16.8 to 15.1 Is this normal for Redline?

I figure 483 race miles is probably further than I should go on an oil change.

It's normal for a new racing engine. I would not be afraid to run the oil for another 500 miles.

Could the motor still be breaking in causing the iron, copper, and lead reading to be high?

Thanks,

Your motor is still breaking in and the copper and lead are trending down. Looks fine to me.
