Just wondering what the healthy recommended daily dosage is?

I try to press the fun button approx. 7-to 10 times a week only, that's about 2 to 3 times per drive (Week-end use only), mainly on the hwy to ruin someone's day.

No seriously, I figure anything this good has to cause a lot of wear to the Engine/transmission.

Is there some sort of recommendation about using the 500E's maximum power? All the time? Once a year?

How often do you press it on yours?
