Your the first person I ever heard that did not have a good experience with lucas. Sorry to hear that. I used to sell Zmax products and most people never bought it due to price. (my store was in a very rural town) so we discontinued it.

 

I buy my zMax products several of the same items at a time online and they run specials. I can get $40 retail for $10 + shipping of the website. I live outside of detroit in the suuburbs and all I can find locally is gas and oil suppliments and they're $20 each. They (the chain stores)are the only ones that carry it. Little parts stores only carry items like Amsoil that I used to have to mail order.

 

They sure had good results with Zmax on Horse Power. I quess the only way to see is to use some and find out.
