it's the same how slick 50 was touted as a miracle additive years ago,,,without unbiased testing it's hard for the average person to see through the marketing campain. the infomercials are very convincing and cater to all of us "car fanatics". we all want our cars to run the best they can and last a long time. i can't prove it or anything,,,but years ago when slick 50 was still kinda new (and you had to shake it up before you poured it into the crankcase-----should have been a red-flag right there!!!!) i put it in my first car, a 76 olds cutlass supreme-V8 4 barrel with around 90k miles. very soon after it threw a rod and destroyed the engine. maybe just coincidence,,,who knows. was running fine before the slick 50. stick to this site (and the link above) for unbiased info. well worth it.66mgb wrote:Wow - that was a great link. Kind of cool to know that Lucas makes oil foam like that. I'm suprised that I haven't heard a lot of bad comments about it before.
