saving gas ? put your truck on display room , or simply don't use it hehehe

 

Here's a comment from it!

"This is simply awesome, but be careful with that. If you plug too many of those to your car, you will in fact start to generate your own gas so you would have to empty your gas tank from time to time". WTF hahaha. If that's true I'm going to order 12 of them. But sadily it's not and it probably just shorts out your truck so it wouldn't start anymore! Hey that's a way to save gas!
