Oxide?????? I've never heard of a problem like this - 6 months isn't that long. You've piqued my curiosity, and I'm interested to find out more about this problem.

 

That really shouldn't be a problem. After dumping the old fuel that was in the tank your car should run fine. Can you describe what your cars doing starting wise?
