I initially chose Green for their dominance in the World Rally Championship. Improvements in acceleration and gas mileage were immediately noticeable. The engine doesn't stutter or gasp for air anymore and runs smoother at all RPMs. It's incredible value for money considering it increases fuel economy, lasts a lifetime (warranted), and filters well. If you want the best, Green or BMC is the only way to go but don't expect them to perform miracles.
