WILCO Turbo Approved 10W-30 API Service SM
Packaged for A.T. William Oil Co. Winston-Salem, NC
By Warren Oil, Dunn, NC
Purchased in: WilcoHess, Harrisburg, PA
Date of purchase: 3/9/2011
The results of the tests conducted on this sample meet the requirements of an API SM, SAE 10W-30 Engine oil.
Note: Although the label on the back of the bottle displays a rectangle around the words "API Service SM," it does not bare the API Service Symbol "Donut." The API Donut is a Certification Mark that identifies engine oils that meet API performance requirements.
Warren Oil contacted PQIA to advise changes were recently made to the label for this brand, and the sample tested by PQIA represents store inventory prior to the change. The new labels display the API Donut. Click here for new labels.

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 Wilco Turbo Approved 10W-30 tested with the API SM ILSAC GF-5 requirements. |

| Viscometrics | ||||||||
|
The viscometrics meet the required targets for a 10W-30.
