what do you think? would this possibly work?

cheers,

Chris:cool:

Sorry Chris, no dice. Leaded fuel uses Tetraethyl Lead (TEL) - which is an "organic" lead molecule. Elemental lead (Pb) is another kettle of fish, and will not dissolve in fuel.

Btw - lead is a pollutant - there are other options.

Lead replacement petrol (LRP) when available used a phosphorous compound to do the same job (sold commercially as "valvemaster").

There is also an organic Manganese compound (MMT) which does the same job, and is used in competing lead replacement additives.

thanks for the info mate!

cheers Chris

Some servo,s insist their unleaded has no ethanol. Is there a simple test to determine that before it rots our diaphrams?.

Not really - HOWEVER - 99% of fuel sold in QLD comes from either the Caltex Lytton refinery or the BP Bulwer Island refinery. If you contact the refinery (or BP /Caltex technical), they can tell you if they add ethanol or not.

They can also tell you who sells their fuel - e.g. shell, mobil and woolies have "product sharing" arrangements with caltex and BP.

Unfortunately some of the minor brands 95 octane fuel also contains ethanol (can't recall which ones ATM)

Best to stick to the majors, as Ben said the big four's come out of a couple of refineries in each state.

I have a Fuelstar fitted to the Alfa. This is a fine, tin particulate cannister that is plumbed in-line and releases tin particles into the fuel as it passes through. This is supposed to do the lubrication job lead used to. The vibration of the engine agitates the canister releasing the tin particles.

I also run only BP Ultimate as it was the only fuel I could verify as having no ethanol content. It is only 98RON but I have been told that it is better to run a lower octane rated, pure mineral fuel than a higher (100RON) ethanol blended fuel in my engine.

BTW, I note that Fuelstar has managed to get a rather dodgy reputation (like Hiclone), but I think this stems from their claims that it is a fuel-saving device. For use in a classic car engine fuel saving is not its primary purpose so I can't comment on that.

Correct! I ALWAYS ask the servo where their fuel comes from when filling up the Alfa if I am using one I don't know.

In NSW/ACT and maybe elsewhere, BP have not sold standard unleaded for about 12 months - it is E10.

Eleswhere in NSW standard unleaded will be dropped in favour of E10 in Jul 2011.

II had a fuel-star fitted by the dealer when I bought the vehicle ( TD5 ) new.
My dealer advised this course of action, because they said that it made the common fuel rail last longer.
Its 10 yrs old now and I have just had the fuel rail replaced, weather the fuel-star made it last longer is hard to tell.
I also have one fitted to my series one 1952 vehicle as a lead replacement device to stop valve seat recession.
One of the addition benefits of the fuel-star is that it leaves the combustion area very clean and no build up of carbon, so no de-coking needed yet. It has been fitted for 18 yrs.

Isn't Fuelstar one of the products banned about 6 months ago from sale due to unsubstantiated or false claims of performance.
