I hear some people say lucas products are snake oil, if that means what i think are they saying it not worth the money or a gimmick?

 

I've grown up with Lucas Products. My father, besides being a carpenter & welder, worked weekends when I was a kid as a mechanic. He was even ona pit crew at the local racetrack on summer weekends when I was pre-school age. His brother is a retired, 38 year Chrysler mechanic. Both have sworn by Lucas products, as well a Marvel Mystery Oil for that matter, since before I was born.
I have not been privy to any scientific data as to how well they work, but I've used them all my life with no detrimental effects, anyway...
