Re: fuel catalyst
Assuming you mean the 'bag of tin balls in the tank' or in-line type, then they're almost universally regarded as snake oil. If you want to use some form of additive, it'd be better to stick to FBHVC approved products (most use Castrol Valvemaster).

Re: fuel catalyst
Eh? Would help a lot if you explained things a bit better. A catalyst makes a chemical reaction 'speed up'.
Unless you're on about catalytic converters? Not that they matter to a Minor anyway unless someone has fitted one to go with an unleaded head.

Never heard of it to be honest. Sounds interesting though.

Re: fuel catalyst
I'm fairly sure what he's talking about is nothing to do with catalytic converters!
There are several 'fuel catalyst' devices on the market that are supposed to magically replace the lead in petrol and stop valve seat recession, etc. They seem to either come in the form of a bag of metallic pellets that you drop into the fuel tank, or an in-line thingy fitted between the fuel pump and carb. As I said, they're almost universally regarded as snake oil, and none have FBHVC approval.

Re: fuel catalyst
Re the link to CW: An unleaded 'device' at £89.50? Hmm. I'll pass on that one, thanks...
Old cars which have ran on leaded for practically all their lives have a 'lead memory' which has been built up over time, making any additive unnecessary unless you cane the engine a lot at high speed.
An additive worth considering is a 1:100 mix of 2-stroke oil in the tank which can't do any harm apart from decoking more often.

Re: fuel catalyst
You don't NEED any unleaded additive etc (and certainly not a 'bag of old balls') - just set the exhaust valve gaps to 15 thou and check /reset every 3000 miles.
Re: fuel catalyst
I have used a catalyst in my Triumph Spitfire 1500 for some years without any additive. I can only say that since I started, the engine no longer runs on, starts easier and seems to run more smoothly. Whether it stops recession of the valves I cannot say.
I know that it is said that its all snake oil and it is possible and probable that some products are useless but it is a fact that, during the Second World War a platinum catalyst was used in some aircraft because not enough aviation fuel of the proper octane rating could be produced.
Catalysts do not change themselves or add anything to the fuel. They act by causing a change in the structure of the material they are in contact with.

Re: fuel catalyst
Definitely snake oil.The only effect these "wonders" have is purely psychological !

Re: fuel catalyst
If your Spitfire tank has a bag of platinum dangling in the petrol, I suggest you may have a very valuable car
In amongst all the "snake oil" statements from non-users, there remains the occasional positive statement from users who have noticed tangeable benefits from using these (tin amalgam?) pellets. If your vehicle ran-on before, and now doesn't, and ifb] nothing else has altered, then the pellets must be doing something! As we are far more likely to moan than to praise, I am happy to give them a try, especially as they have a money-back guarantee!!

Re: fuel catalyst
My car doesn't run on /idles nicely etc etc - and it doesn't have a bag of balls/'catalyst'/additives/unleaded head. Am I missing out on the fun ???? It's all a load of nonsense........
