USDOT rule was no more than 100 gallons of fuel for the motive equipment being carried. So no more than 100 hundred gallons of methanol for the sprint car.

Please look at the DOT reg's though because it has been awhile for me. You can always call the Scales Office or Trooper Office and ask their commercial guys questions.

I would always help anyone that called us and I usually ended up learning something new in the process. And don't ask the regular patrol guys they usually won't know !!!
