On a slightly different track , many years ago ( 1980’s) when they reduced the lead in petrol there used to an advert for some tin/alloy pellets ( full cat ???) That you placed in the fuel tank that allegedly were based on WW2 tech used for aero engines , these Pellets improved the fuel and restored performance .
Has anybody used this type of fuel additive and what were the results?
Looking to use something of this nature in an old engine, not fitted with stellite valve, seats.
Hi Barney I knew a guy who toured China & surrounding areas back in the seventies on a stationary engined 500cc Triumph, he had one of those things in his tank to deal with the different grades of petrol he could find out there. I did have a look at it & it looked like metal balls enclosed in a wire cage.
I personally used to use something called FS1, it was a heat seeking molecule lubricant that treated the metal of the valve seats, one treatment lasted forever.
That was before Castrol bought it & put it in their Magnatec oil, I'm not sure if you can get it individually now unfortunately.
