Paddy_Crow is right. I was a car builder for about 18 years. During that time I was exposed to all the water injectors, whirlygigs, pour-in potions and add-on gizmos people could come up with.

The biggest efficiency advances in internal combustion engines in the last couple dozen years are electronic fuel injection and ignition systems coupled with the "Brain" and sensors that interact with and control them.

I been driving a little old Suzuki Samuari 4X4 for close to twelve years now. I even "Customized" it a few years ago. I put a sticker on the windshield that says, "BUMMER". I always look for a "HUMMER" to park it next to when I go to town. <img src="/forums/images/graemlins/grin.gif" alt="" />
