This is one of the dyno sweeps on a 1986 Porsche 911, 3.2L air cooled engine.   The powerplant was filled with a popular synthetic race oil, run, and then compared to PurÖl Elite synthetic.  Both oils tested were of the 10w-40 SAE grade.  Both oils were drained, tested 3 times, with a reference oil inbetween, back to back, in A-B-A testing fashion.
The results: 6whp gain with PurÖl, and a 5ft/lb torque on the 146whp engine.

PurÖl  is the best oil we have ever tested in our facility.  Kindly forgive the poor sound quality, as the microphone was set to higest sensitivity.
