Does the brand of fuel (of the same octane) make a difference in horsepower? How much power does 95 octane fuel make compared to 91 octane pump gas? In this video, "Dyno" Don MacAskill and Lake Speed Jr answer these questions.

After some recent questions regarding the consistency of today's pump gas, the team at Shaver Specialties Racing Engines set out to isolate and then eliminate any variables in the fuel used in our testing. That’s what prompted these test, and this video shows the results.
