Yeah. If I ever see rust on a car I know it's not from AZ.

 

that's a total gimmick too.. just like the dealer likely is.. they likely run better because of what they added to the tank in the process..

it's a shame that the gimmicks undermine the real thing, and to the point folks start to believe it's all a gimmick... The good news is, unless you get a hold of some bad gas along the way, your injectors should hold up a long long time..
