Anyone tried this - Bultaco Pursang, Matador, 2 stroke fuel stabilizer?

[jack2]

Hi,

I stumbled accross this on ebay.

Has anyone tried this?

It seems like a dream for petrol users - or am I just dreaming?

[ditchcrawler]

I thought most outboards were 4 stroke these days

[Grace and Favour]

OP - have you thought of using StarTron petrol fuel additive instead?

Quite a few of the better quality 2T oils suitable for air cooled engines [ in my case pre mix for chainsaws] contain a fuel stabiliser . came about as the petrol the US in perticular contains various quantities of Ethanol causing the fuel to ``go off`` very quickly I presume the oil suitable for liquid cooled motors is similar

Hi,

 

I am going to try the Star Tron instead. I seems to get good reviews! -It could save a lot of people a lot of fuel if it works!

[Peter Reed]

Snake oil?

I think you will find that stabiliser does nothing in regard to bettering fuel consumption the main purpose is to lengthen the shelf life of the fuel

Sounds like it to me. Here's some of the technical bullshit on the ebay listing:

 

What is Fuel Cat?

 

FUEL CAT is an amalgum of metals, with the main one being Tin. Together they form a catalyst that acts like a permanent octane booster, a combustion enhancer and combustion chamber carbon deposits cleaner. When the fuel flows through FUEL CAT fuel catalyst, a chemical reaction instantly takes place. The shape, temperature and speed of the burn are transformed, making combustion more complete and even, contributing to greater engine efficiency. FUEL CAT fuel catalyst aids the combustion process by ensuring that fuel is highly uniform, potent, consistent and stable. Just one FUEL CAT is all you need. It is effective for up to 400,000km.

FUEL CAT removes and further prevents the build up of carbons, gums and waxes. Internally, your engine will be far cleaner and more efficient. It is particularly effective for injector needles, nozzles, valves, piston rings and oil contamination. After the first 2,000km of using FUEL CAT, the oil in your engine can become particularly dirty as it removes carbon deposits from the engine. All you have to do is change the engine oil, and thereafter it should stay noticeably cleaner for a longer period. By keeping your engine clean, FUEL CAT optimizes compression and seals the combustion chambers from the crank case, preventing contamination of the engine oil.

 

How does FUEL CAT achieve Fuel economy?

 

The FUEL CAT fuel catalyst induces chemical reactions among fuel molecules at low temperatures (such as those our vehicles and fuel tanks experience) and it returns them to their original state at the conclusion of the reaction ready to initiate a new sequence.

Fuel molecules have a tendency to cluster together. At the point of combustion, the outer molecules protect the inner molecules from being covered with oxygen, resulting in some of the inner molecules going un-burned and blowing out from the exhaust as emissions.

When fuel is passed through the FUEL CAT fuel catalyst just prior to combustion, a reaction occurs which separates the clustered molecules so more of the fuel molecules surface area is exposed to oxygen at the time of combustion.

A comparison would be if you put a piece of charcoal in a furnace for 30 seconds. The result: the oxygen only surrounds the outside of the charcoal only allowing the outside of the charcoal to burn. The oxygen does not reach the core of the charcoal as it was protected by the outer layer. If you crushed the similar-sized charcoal into a powder, spread it out and place it into a furnace for 30 seconds, more of the surface of the charcoal would be exposed to the oxygen and a larger percentage of the charcoal would be burned.

This is what happens as the fuel passes through the FUEL CAT fuel catalyst. Clustered fuel molecules are separated so more oxygen can cover a larger surface area of the fuel molecules at the point of combustion.

The more fuel burned, the more energy created and less un-burned fuel will be emitted out from exhaust in turn reducing pollution.

A more efficient burn results in less fuel required to make horsepower. A cleaner burn means better oil chemistry and cleaner engine parts resulting in reduced maintenance.

 

How does Fuel Cat keep your engine cleaner?

 

Fuel Cat not only optimizes burning of fuel, but also keeps the engine clean by leaving no unburned fuel that can then turn into carbon monoxide, unburned hydrocarbon and free carbon (as soot) emerge from the combustion process. The unburned hydrocarbons and free carbon form gum or wax, and are loosely described as carbon deposits, which are baked hard, in the combustion chambers, onto piston crowns, valve heads (particularly the exhaust valve) spark plugs and interior surface of the combustion chambers. The piston ring can also be seriously affected and eventually become stuck in their grooves.

Fuel Cat regulates the speed and temperature of combustion which prevents micro welding between valve and valve seats; thus preventing valve seat recession.

Appears to be the same old snake oil but with a differnet name.

 

 

Fuel Miser was another one I think but that went in the fuel line and had tin balls if I remember correctly.

For goodness sake its an Ebay ad. Thats the wild west as far as consumer protection and advertising standard enforcement is concerned (as far as I can see).

 

This type of product has been being promoted for as long a is have been in engineering. In the early days it claimed that it allowed Spitfires to run on low octane fuel. If it did as is always claimed why has no major manufacturer fitted them as standard as an easy way to meet fuel consumption and emission criteria - they have had 60 year to evaluate it?

Quite. My take on it too. I meant to say something similar about why no vehicle manufacturers are using the 'technology'. This is because they've established it doesn't work. Why else would they pass up a chance to bring to market a significantly better vehicle and steal a march on their competitors?

 

I disagree about ebay though. They offer at least a limited amount of consumer protection. If the item fails to be delivered at all they will ensure you get a refund for example. Slightly better than the wild west I reckon!

Absolutely agree Tony. When I was running my garage business (specialising in hi-tech and engine tuning) we had a company try to get us to endorse one of the magnet and tin balls type fuel conditioners, as used on Spitfires. They gave me one to try on our van and I ran all sorts of tests for mpg, emissions etc. We found (surprise, surprise) that there was absolutely no detectable difference at all. When I reported that we found no difference they tried to tell me that we had had a defective device..........yeah, sure, a tube with magnets and tin balls defective? Pull the other one.

What they do not do as far as I have been able to see is provide a simple way for members of the public to alert them to breaches of the various consumer acts. They seem to require you to register and deal with then via email.

 

They had what was clearly described as a "marine fuel filter" for sale yet it clearly had a plastic drain screw (not a metal/plastic composite one). In my view it was a false description but could find no way to get the advert changed or alert Ebay. If only they were made jointly responsible for their sellers actions and inactions then it would be cleaned up very fast.
