Re: The best thing I have ever done for my HT...
I've never been much of a believer in miracle poops and goops that provide incredible results...I never did do the slick 50 thing or any of the others for that matter, but if you've had good results that's all that matters! It sounds like you got your money's worth by the fact that your engine is running so much better.
Who knows, maybe these people have actually created a goop that works!
I do know Amsoil products are really good! There's a technical basis behind Amsoil that quickly absolves thier company of running a smoke & mirrors show.
