Has any of you chaps/chappesses ever used one of these Catalyst type thingumyjigs, 4 wee bits of metal in a plastic webbing type tube which gets placed in the tank to facilitate lead replacement? I was thinking of using one instead of the usual additives but I'm a bit unsure of the whole lead/unleaded debate. My old Landies don't seem to mind unleaded in their unconverted heads but I'm a wee bitty hesitant in relation to the delicate woodie.
Fuel Catalyst....good idea/bad idea?

waste of money... Here he comes...........................

no i dont use one , i havent heard of any one having any problems with them , they are supposed to work , but who knows , the suppliers and manufacturers would say that wouldnt they , to sell them , i use a devise called a FUEL SAVER , that is supposed to do the same job ,it fits in the fuel pipe , aly tube with some thing the fuel passes over and pics it up on the way, but i only have there word for it lol , but anything is worth a try , Cant hurt !! , The only true way is to have your head converted , or replace it with one allraedy done , Expensive though ,

Catalysts are a waste of time and money. Practical Classics ran tests when unleaded first came in, and catalysts failed completely. There are additives, usually liquid, that can be put in the tank, and these do work. Use one approved by the FBHVC, such as Castrol Valvemaster. There are other debates about whether you need an additive at all - I would say yes, others would say no. However, I think that virtually all of us agree on catalyst type products.

just stick the valvemaster in untill the head needs changing

Thanks Guys,
Ah'm off to the shrink now..........., seriously though, you have been a help.
A' the best

Here he is..... No need for anything - set 15 thou exhaust gaps and check/reset every 3000 miles... The fuel catalysts are 'snake oil' and [ content removed , by moderator - Ray]
worth using is Tetraboost - which contains lead and effectively makes 'leaded' petrol from unleaded. Not cheap though!

That took longer than I thought Roy,

I've been away driving steam trains all day.....

The additives that have passed independent testing are PROVEN to work.
If you want to use an additive - it's worth using one of those.
Bear in mind that others available on the market were tested and FAILED the independent tests - many making no improvement at all compared to the baseline 'unprotected' engine. Swapping between additive types is also not recommended as certain combinations cancel each other out, as there is a cumulative effect from what's left behind.

Fuel catalysts:
The MMOC has previously reproduced articles (in club mag) on the lack of performance of various fuel catalysts, in order to help spread the awareness. Classic car owners have enough to spend money on without falling victim of false claims.
Based on the untold millions that the car industry spend on fuel economy research, if tin pellets / magnets etc.. were actually a benefit, they would be fitted on every new car sold - they're fitted to none at all.
