Hello and welcome to GH.

You are (as far as I'm aware) our first Silverado Hybrid owner to these boards. Although I can hardly claim any real knowledge, I would think that you'd be best off either leaving it as it is, or having someone periodically drive it if that's agreeable.

A quick note for others here who may not know, the Silverado Hybrid is a start/stop hybrid, no large scale battery pack to worry about in the same way that other hybrids out there does.

Ryan, I, and I'm sure several others here, would like to know any thoughts you have on your vehicle, and any good/bad points you've noticed either so far, or in retrospect. Even if you don't post that right away and do it months later, I'm sure people would still like to hear your perspectives.
