Fuel catalysts in Hurricanes

I based my assertion on the following :-
VW Type 1 1300cc twin port engine fitted to 1963 standard export Beetle. This would originally have had a 1200cc motor driving a standard gearbox - sorry can't remember the final drive ratio.
Pre fitting the catalyst the 8 gallon tank would give 200 miles to dry- post catalyst this rose to 214 miles e.g. 7%
I commute in the car 50 motorway miles a day at 50 mph and have done since 1996. I fitted the catalyst in 1998.
I found out about it from reports in the journal of the Civil Service Motoring Association who endorsed it. I have no connexion with the people who market it but am nevertheless a satisfied customer.
Incidently I copied in their web site in answer to the original request for more info on Russian Hurricanes
Hope this clears up any misunderstanding

Any connection with Shell's ICA (Ignition Control Additive) put in all Shell petrols worldwide in Fifties/Sixties?
When I joined Shell International Marketing in 1959 on our intro course we were taught that ICA had been developed in WW2 by Shell as emergency measure to inhibit spark plug gumming up. To get ultra long range bombers were being operated at thin mixtures / low revs with the result (and I can still quote exactly from our Shell lab tutor) that "at one time we were losing more Lancasters over Berlin from engine failure than from enemy action". For some reason ICA was later banned for aviation use but for many years was the key USP for our (Shell) retail sales.

Shell fuel additive
To: 4wings
I believe the additive you were alluding to (if I am correct) is TCP or Tri Chresel Phosphate (possible misspelling). It was added to the fuel to scavenge the lead keeping it from building up on the valve stems and the plugs. When I was in the USCG working on helicopters off of an Icebreaker we had two helicopters. One was an HTL-1 (Bell 47) that ran on unleaded or very low lead 80 octane gas and the other was an HO3-S (S-51) that ran on 91 octane fuel that had a lot of lead in it. However we only had one fuel tank to draw from and it had 91 octane fuel in it so we periodically added TCP to the fuel storage tank to minimize the lead induced problems on the Bell. Even with the TCP in the fuel we never got more than 60 hours on the Bell plugs and the engine had to be changed at about 400 hours. The TCP had no effect on the S-51.
