I ran the first dosage RX for 1000 miles in the crankcase then filled with mobil drive clean 5w30. Here's my usage since then(expressed in miles since the change):
750mi - down 3/4qt topped up
1300mi - down 1/2qt topped up
1700 mi - down 1/4 qt topped up
2000 mi - down less than 1/4qt topped up
I added another bottle of RX at 2000 miles. I've also noticed the oil spots on my driveway seem to have stopped appearing lately. I wouldn't be surprised if I was leaking more oil than I was burning. I'll keep everyone posted with my results when I get this next 1000 miles of Auto-RX out of the way. I had initially not seen any improvement, but as time progressed I could definitely tell a difference. I spoke to frank directly about a treatment schedule and it's posted in another thread in the Car and Truck Gas Engine Oil section under the topic "freakin saturn, I give up". As you can tell I havn't given up after noticing such an improvement. All I can stress is that DINO oil is extremely important.
