You don't need a 20 weight oil unless you have oil pressure problems or your motor is built really lose.
You'll give up ET with the heavy oil and it won't travel as freely on cold start.
You don't need to change your oil after every race weekend unless you are getting about 75 passes on it, or running alcohol, methanol or Nitromethane which would require more frequent oil changes.
