In what area's did you find oil? If its near the front and rear diffs, the stock oil is very light and leaks through the diffs, mine was the same way outa the box. I took the diffs out and filled them with a thicker oil, 100k. If its near the shocks, is likely a loose or broken shock fitting somewhere. Those are the only two places that would have oil leaks.

If your new to this, especially to brushless and Lipo, I would highly suggest reading this threads to prevent destroying your Lipos and or melting your ESC
