Formula 300 All Weather Motor Oil, API "SF/CC", SAE "5W30"

Hicks Oil, Doquoin,Il


Purchased in: C-store, Olive Branch, MS

Date of purchase: 10-5-2011







All tests conducted on this sample meet the specifications for SAE 5W-30 and are consistent with API SF/CC engine oil.


Advisory: This product is labeled as meeting API SF which is an obsolete specification and is not recommended for passenger cars built after 1988. In addition, this product is labeled as meeting API CC which is an obsolete specification and is not recommended for diesel engines built after 1990. The product label does not adequately warn consumers of this limited use.

c-Test Method for metal analysis is ASTM ASTM D5185.

d- Although silicon is used as an antifoam additive in lubricants, concentrations above 7ppm have been linked to contamination from abrasive material,

Formula 300
The American Petroleum Institute sets forth a number of laboratory and engine tests required to meet an API SN ILSAC GF-5  performance specification. Although laboratory tests alone cannot be used to establish if an engine oil meets API SN, they can be used to determine if it doesn't.

The following is a comparison of the test results for the sample of Formula 300 tested with that of SAE 5W-30


The viscometrics meet the required targets for a 5W-30.
