I think we would all be in serious trouble if carbon molecules suddenly decided not to 'clump together'. Mind you, the older I get, the more my morning face seems to tell that this ungodly phenomenon might well be a distinct possibility
These things were being toated adout the LandRover Mags about 10 years ago & were found to be crap.
I know someone who put one on his diesel RangeRover & it actually made the mpg worse.He got his money back.
If these things are so good,how come they are only on e-bay & not on general sale at the usual places ie Halfords,etc.
I personally woundn`t go near one as I think they are just a scam.
