I've been using Lucas Upper Cylinder Lubricant for the last 1-2 years on my two cars. Just wondering if this is considered to be a decent product. I like the reasoning behind it's intended use, but I really don't have much information to go by other than the manufacturer's advertisement. Couple questions. Firstly, is there any harm in running this product in a turbo engine setup, I'm concerned because it seems to be more of an oily substance rather than a solvent. Secondly, I occassionaly get a puff of white smoke on start up (on my non-turbo vehicle) when my fuel tank level gets low and after using a treatment of this stuff. I don't know if this product is heavier than fuel and settles at the bottom of the tank. Is this any cause for concern ?. I know this stuff burns off as white smoke as one time I poured a bit into an open intake manifold system while I was changing out my spark plugs, and she burned off huge clouds of white smoke that time. I get really good fuel economy on both of my vehicles and low oil consumption, but I can't really atribute it to this product despite running it for a decent period of time. I'm skeptical about it's claim of increasing the burning power of combustion chamber fuel. Any opinions on this product would be good to know. thanks
