I've seen many commercials for this product and credible guy like Carroll Shelby is endorsing it. I remember using Slick50 while back thinking it will protect my engine but instead had negative effect.

Carroll Shelby sold his name to Dodge (MoPar) to stick on some sh!tbox in the '80s. He's no credible anything.

Always remember, these people are PAID for their endorsements. Celebrities, sports stars, politicos... Nobody should ever be considered "credible" if they're getting paid for their "endorsement".

+1 on that...unless you use Crisco as engine oil I think additives are just a way for business companies use to squeeze out some $ from you...

save you money for a new fuel, air, oil, micro air filter

my 2 cents

The claims just seem a bit much - regular Mobil 1 changes should be all you need.
