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.

Terrible Herbst 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.


Whereas the Cold Crank results for this sample exceed the maximum of 6,600 cP, it falls 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.
