Re: Is there a difference between truck diesel and auto diesel
In some states there are specified "tax exempt" pumps. To use these requires a valid tax certificate to be posted on the vehicle being fueled. Refueling from these pumps without a valid certificate for that state is illegal and carries hefty fines. You and I would not be able to use enough fuel in a year to recoup the certificate cost.
The fuel has the same properties. The truck nozzles are larger and will fill more rapidly, too rapidly for our relatively small tanks. That and the possibility of the previous tax issue are the only differences.
