What we tell our DEers in the safety mtg would apply here:

If you have enough early warning, get off "the line" before dumping a bunch of oil on it. Your fellow competitors will find it much more enjoyable. You might want to also let your competitors know your situation so they don't follow too close and get involved in the aftermath.

I know nothing about rally cross, but this DE rule might also apply there: if someone has a fluid situation on the track, the track charges our club for the speedydry, which we pass on to the driver. It's been a while, but I think we were charged $20 / bag when this occurred 4 yrs ago. So don't be surprised if you're handed a bill for your entertainment.
