Wouldn't matter, 6inarow... but it was after...

These things have been around, essentially unchanged, since the 1920s. There are millions of them out there... somewhere.

Just take one of the statements from the RAC 'test':

 Quote:
1. The RAC's tests [see amendment] concluded that for Fuel Cat to have any effect at all the pellets would have to be dissolved or mixed with the fuel. In practice this does not happen which means that Fuel Cat cannot meet the claims made for it.
I could certainly see wear in the pellets, that they were being consumed. Fact is, they are only required to break away at a minute rate to work.

The pellets are held in place in a steel spring, and the canister is attached to the engine so it gets fed vibrations. This means that there is friction between the tin and the steel, the tin is slowly broken away and joins the fuel stream.

Then there is a catalytic reaction during the combustion process, as I understand it.

And yes, nobody I've ever struck who's used them has found they've failed them. And nobody I've ever struck who was categorically against them has ever used them or had anything to do with them.

Mine saved me a head replacement job, that was what I needed. Until then I was using all kinds of stuff that was supposed to help... zinc-rich oils mixed in the fuel, fuel additives etc, but I lost that 15 thou in 1800kms all the same.

And I lost nothing for the next 80,000kms. I still wasn't ready to change heads, though, so I followed the instructions and cleaned it up, reassembled it and got the next 80,000kms out of it before the same thing happened.

When it stopped working, by the way, it stopped working altogether. The valve seats started to go all at once, rapidly eating away. I was lazy, just adjusted them a couple of times and hoped for the best. But then I found out I could clean it up and so I got it stopped again.

Second time round I put on one of the heads I'd had the seats replaced in. But I'd got two years heavy running out of it, I was able to choose when I wanted to change the head rather than do it when I had to, and it's still there to go in another car when it's needed.

Jason... as far as a control group and controlled environments go, yes, I would agree. To a point. But I was my own controls, I am in total charge of my cars, driving them, fuelling them and maintaining them.

And by the way, what is the point of having the tin in there?

To replace the lead, right? Isn't it logical that it might work?
