Even though the sportsman don't have penalties (I'm not dead certain this is true actually)....
Sportsman most certainly do have to abide by the policy which applies to ALL participants at National Events ... See section 2, page 9 of the 2015 NHRA rulebook. As well, this statement appears at the beginning of each category in the rulebook ...
"Any competitor who causes an oildown while participating at an NHRA Mello Yello event will be subject to fines and penalties as outlined in Section 2 - Oildown Penalties."
Jim I was referring to the lack of a penalty table, or absolute policy. What I've seen at National events is where if they determine a sportsman (let's further say non TAD/ non TAFC) oils or deposits liquid on the track, they will tell you that if you do it again that same event you will be fined $500. I know of two instances last year where people in our class received that type of communication.
Here is the rule ....
OILDOWN PENALTIES
Oildowns and, more important, downtime associated with
cleanups affect everyone at an NHRA Mello Yello Drag Racing
Series event, including spectators, competitors, sponsors, and
television viewers. With curfews and schedules, oildowns in both
Mello Yello and Sportsman categories have caused in some
cases cancellation of qualifying sessions, early start times, and
very late conclusions to the respective sessions.
In an effort to eliminate downtime due to oil cleanup, penalties
may be in effect at the 24 NHRA Mello Yello national events.
Penalties may be imposed on teams depositing oil on the
racetrack surface during any qualifying and/or elimination round.
Any contestant demonstrating a flagrant disregard or repeated
violation will be subject to disciplinary action as deemed
appropriate by NHRA in its sole and absolute discretion. Such
action may involve monetary fines, denial to participate at
national events, and/or suspension of competition privileges.
The Event Director’s decision is final in determining oildown
violations. There is no provision for review of decisions of the
Event Director, his designee, or other NHRA event officials at
racing events. The reason for this is to ensure that there can be
finality with regard to the events that are run. To provide for an
appeal of all actions or inactions of the Event Director would
result in a delay in the determination of literally every NHRA
national event. Such interminable delays are unacceptable to the
sport, the participants, and the spectators.
