Today I learned that when oil is delivered to your house, it is required that they adjust the temperature of the oil before filling your tank. Because the oil expands when it's heated and contracts when it's cooled, this process is necessary. Here's a word from Hess:
"Industry standards require that it be priced at "net gallons" or the volume it would occupy at 60 degrees Fahrenheit. Temperature correction is the amount #6 oil is adjusted to equal its volume at 60 degrees Fahrenheit. Temperature correction safeguards you by ensuring that you receive the amount of oil you pay for."
