My 3.8 engine was quite oxidized because it sat for so long before I bought my "Nikki." Some guys at the local car show told me the Marvel Mystery Oil gets the aluminum cleaned up and takes the oxidation right off with a little elbow grease.
I stopped at a nearby Dollar General and bought a bottle of that stuff for $3.00, and all I can say is wow. It seemed to chemically get rid of the oxidation almost immediately.
