AMSOIL Diesel Cold Flow Fuel Additive

Understand this product

Diesel Cold Flow is a preventive treatment aimed at wax-related fuel-filter plugging in cold weather. Its product information covers diesel fuels including ULSD and biodiesel, with performance depending on fuel characteristics and treatment conditions.

Apply preventive treatment according to the temperature and mixing instructions before a gelling problem develops. It is a different maintenance tool from Diesel Recovery.

Diesel fuel-system maintenance

Choose the treatment by its purpose: injector cleaning, cetane improvement, cold-flow prevention or recovery from gelled fuel. These jobs are different, even when products share the same shelf.

No universal vehicle fitment is implied by this listing. Use the exact product or part number when checking application information.

Use it as part of a complete service plan

Plan preventive cold-weather treatment before fuel wax forms. A recovery product serves a different role after a cold-weather problem occurs. Persistent starting trouble, smoke or loss of power warrants diagnosis rather than repeated additive use.
