The specification for cetane number in Canada is 40. Diesel producers usually blend a diesel with a cetane of approximately 41-42 (usually closer to 42).
The cetane improver in Husky's premium diesel additive, DieselMax, increases the cetane number by 1-2 cetane numbers, therefore, the cetane number of DieselMax is between 42 and 44.
We hope this helps to address your inquiries. If we can assist you further please do not hesitate to contact us.
