On my 96 Saturn SL2 DOHC with nearly 106,000 miles, I added 9 ounces of Auto-RX about 2000 miles into a fill of Chevron 5w30 SM.
At 3,000 miles into the fill and 1000 miles on the Auto-RX, the oil was 1/2 qt low. I topped it up with more Chevron 5w30.
Yesterday, at 4,000 miles into the fill, it was only 7-8 oz low. I topped it up again, and will run it until 5000 miles before I do an oil/filter change to initiate the rinse phase.
Has anyone else noticed a similar drop in oil consumption during the clean phase of Auto-RX?
