I think it does. When you lift on a auto car, it upshifts and keeps RPM low. When you drive spirited in an MT car and you lift, you usually do more engine braking at a higher RPM. I can definitely see where downshifting, and more importantly engine braking, can have an adverse effect on oil consumption.

You're assuming that the grounds in place from the factory are optimal, which they usually aren't. They WORK, but they aren't the best.

If you think you'll benefit from a grounding kit, then just buy bulk wire and terminals and do it yourself.
