If you haven't seen that CBC Marketplace episode, you can view it on line for a good laugh.
Pump Fiction
Go to the 3' 40" mark where CBC Marketplace drives their test vehicle to the Canadian Automotive & Trucking Institute.
Marty, an instructor of over 20 years has the car run on their test jig on Regular and then on Premium. This gets good.
Marty thinks it'll take less HP to run on Premium.
God, the blind leading the blind. No wonder we have dumb techs.
On a test jig with the same car, it will take X horsepower to run at the same speed no matter what fuel is in the car. They're not even taking any fuel consumption measurements.
Listen to the rest of the chit chat between Tom and Marty.
This is hilarious.
