Terrible Herbst Racing Motor Oil SAE 5W-30
Distributed by Terrible Herbst Oil Co. Las Vegas, NV
Purchased in:
Terrible Herbst, Las Vegas, NV
Date of purchase: April 28, 2011
Advisory: The sample tested does not meet the NOACK Volatility requirements of an API SM ILSAC GF-4 5W-30 Engine Oil. The initial test result of 15.9% NOACK volatility, and the recheck at 16.6, however, fall within the API acceptable "Expanded Range" of 16.62% maximum for an API SM ILSAC GF-4 engine oil. Whereas the Cold Crank results for this sample exceed the maximum of 6,600 cP, it falls well within the API acceptable "Expanded Range" of 7,082 for a 5W-30.

The American
Petroleum
Institute sets
forth a number
of laboratory
and engine tests
required to meet
an API SM
performance
specification.
Although
laboratory tests
alone cannot be
used to
establish if an
engine oil meets
API SM, they can
be used to
determine if it
doesn't.
What follows is a comparison of the test results for Terrible Herbst 5W-30 as compared to the API SM ILSAC GF-4 requirements. The API limits for each test are shown by the yellow bars. The test result for Terrible Herbst 5W-30 are illustrated by the horizontal line. |
||||
| Viscometrics | ||||
|
The Cold Crank results slightly exceed the maximum of 6,600 cP, however, they fall within the API Expanded Range" of 7,082 for a 5W-30.
|
||||
| Volatility | Phosphorus | |||
The volatility
of the Terrible
Herbst 5W-30
sample tested does not meet
the
specification
limits
required for an
API SM ILSAC GF-4
designation.The
initial test
results of 15.9%
NOACK
volatility, and
the recheck at
16.6 does
however, fall
within the API
acceptable "Expanded
Range"
of 16.62%
maximum for an
API SM ILSAC
GF-4 engine oil.

 The phosphorus content in Terrible Herbst 5W-30 meets the requirements for an API SM ILSAC GF-4 designation.
