M.B. Doc, you hit the nail on the head when you say the oil is expensive. I was qouted $100.00 for the several ounces the supercharger holds and $50.00 in labor to change it. Now that's expensive oil!! Thank God Mobil 1 0W-40 isn't that much or we all would be doing oil samples on our engines to get every last pennies worth.
By the way, I was reading a thread a while back about top speeds, I know you've had to have been on I-16 between Macon and Savannah and indulged your right foot. Am I right? That's a heck of a run down there...........
