The Outlaw preformance products

Hey i was just wondering if anyone had any experience with quaker states Outlaw series of oil and fuel additives, i know the stuff labeled "barely street legal" is probably crap, but they have stuff they say is off road use only for less than any of the other non street legal brands, worth the money? oh and they have it at my local big lots store for half the price of menards for the same product.

What are you using this stuff for? If you think it will increase any performance your wrong.
