Frequent Questions

Are the EPA approved test methods for diesel automatically approved for use on kerosene or heating oils, or must the test method be approved for each product?

EPA does not require testing on heating oil. Consequently, there is no need to seek approval from EPA regarding the method used for the testing of heating oil properties. Any testing on #1 diesel fuel (kerosene) used in highway diesel or diesel nonroad, locomotive, or marine engines required by EPA must be conducted using an approved test method. The test methods approved by EPA for testing of the properties of #2 diesel fuel are also applicable for the testing of #1 diesel fuel.
