I have been there, I have also dumped oil on track, twice now but I pay attention and was off the line and in the dirt asap when I blew the engine, 5 holes in the block, second time the a failed fitting and when I hit the brakes I was backwards at 110MPH, that was rather interesting. I barely got any oil on the track both times and nearly all quite away from the racing line, they did not even red flag it. Not in the ST, it still has 294 miles on it.
