The difference the Shell V power gas offers is amazing! Chevron was the best for years, but what ever Shell is putting in their V power fuel works! With modern cars, they can adjust for the fuel and you can feel the difference and see it on the Dyno. For older cars like the Z running the 80's tech factory ECU without aftermarket knock box, tuning for lower quality fuel makes some sense, but Shell is everywhere, so I would rather have the power and use the known good fuel.
