Storage Tank

 Suction heater recommended

Storage Life Indefinite when kept at recommended temperatures

Special handling:

Viscosity modifier additives are sensitive to contamination. The most common problems result from their direct contact with other contaminated motor oil and gear oil additives. Very small levels of additive contamination can produce gels that are difficult to solubilize in oil. For this reason, all equipment used in the manufacture and transfer of viscosity modifier additives be thoroughly cleaned and inspected to ensure no residue from previous additives is present.

According to the "North American Emergency Response Guidebook for Shipment between U.S., Canada, and Mexico for All Common Carriers" defines this product as "NON-COMBUSTIBLE" for transport.

The effectiveness of this product varies depending on the composition of the lubricating oil to be treated. Alken-Murray recommends that clients test this product with the selected oil, using the IPI standard test for pour point depression, to determine the lowest temperature at which they may safely employ treated oil.
