Just a quick update, I changed my oil to Quaker State Defy 3 weeks ago and only had to add 1/2 qt at the 1700 mile mark, I'm at 2,100 now. That's a vast improvement, less than half as much burn as before, I'm not saying QS is the cure I mean, I've changed the oil 5 times in the last 6 months, used MMO and Sea Foam, and all the top offs, I'm sure I did a good amount of cleaning. If my consumption stays this low (relatively) I'll stay with Defy and see if it keeps improving or holds steady. I just wish the Shell stations I pass by regularly honored the FRN.
