SOOOO I finally got around to opening my emptied gas tank yesterday to give it a nice oil bath for the winter. Using a flashlight I examined the (very limited) areas that I could see, and spotted two extremely small red rust dots. I'm talking 1mm at the largest, and the other was even smaller. I sloshed the tank well with oil and plan to leave that in over winter, but I'm concerned about the rust spreading. Will the oil 'suffocate' it sufficiently, or is this going to turn into a gastank-coating project...?
