This is just my opinion, as I don't know the law in your state, fact is I don't know what state you are in. But here, off road diesel, means just that, you can use it in anything that is not licensed to be used on the road. Going to a station to buy some is not road use as its not licensed with plates. I bought 2 5gal cans of it today, I have to drive my car to get mine, as its about 15 miles away, but in a regular pump that states off road diesel. Paid $2.49.9 per gal for it.
