The November, 2012 issue of High Performance Pontiac features an in-depth test of BRAD PENN® PENN GRADE 1® motor oils using their Project Pure Poncho (aka The Mule) test engine, a 467ci mill with ported 6X cylinder heads, a hydraulic roller camshaft, and a street-friendly 9.1:1 compression ratio.
The protocol was to run a series of oil weights through the engine and see how it responds in horsepower, torque, and oil pressure. The tests were performed using three different viscosities of BRAD PENN® partial synthetic oils to gauge the effect on power: SAE 0W-30, SAE 10W-40 and SAE 20W-50.
The test engine already had BRAD PENN® 30-weight break-in oil in it. The protocol of the test was to baseline the engine with the original break-in oil, and then drain and refill with each product, along with a new ACDelco oil filter. Three to four runs were made with each grade of oil and the results tabulated. Much care was taken to keep oil temperature for each test as close to identical as possible, while maintaining similar water temperature.
In addition to the Project Pure Poncho Oil Test results, the report, “In the thick of it—exploring oil viscosity and its effect on engine performance,” goes into detail about The Meaning of Friction, The Oil Wedge Theory, Functions of a Lubricant, Desired / Undesirable Oil Properties, as well as a look at the development of modern motor oils.
Without going into great detail, the bottom line result of the testing was this:
“The BRAD PENN® oils fit the needs of the street/strip Pontiac owner in every grade offered.” The tests confirmed that “Brad Penn oil is formulated to eliminate the lubrication concerns of Pontiac owners. The oil has all of the necessary phosphorus (1,340 ppm) and zinc (1,500 ppm) that is required for any type of camshaft or valvespring pressure. No further additives are required.”
