Ebay linky



Works up to 100,000 miles in a Chevy 5.7L apparantly.

that's a hell of a lot of fuel.

Do you reckon that that's automotive grade chicken wire surrounding them special pebbles that increase the octane rating and protect your valve seats?

LOL!

Do you think if you've got twin tanks you have to buy two or does the magic stuff go through the fuel lines back up into the tank without the magic pebbles.

You wonder why anyone would buy Avgas when they can just stick some of these babies in the tank!!

Perhaps they'll let me distribute them to the formula one teams.... Haha! This time next year......

Always thought it a load of rubbish, take a look at:

I have actually seen in other forums proffessional LPG fitters recommend this crap as essential to prolong the life of valves when running on LPG.

Of course if zinc is such a good catalyst that it raises octane levels and removes the need for lead car manafacturers would just do a really thick zinc galvanising to the insides of their tanks

how long will it last? forevver since it does FA - it is hardly likely to be dissolved by the petrol.

think of it as an idiot tax.

HOW LONG DOES IT LAST? Some companies claim unbelievable mileage but you cannot claim this as cars and motor cycles differ in the amount of fuel they consume.

We therefore state that our product will be good for 100,000 miles.

Prodrive fitted a set to every P1 impreza in the country.

Claimed it made up for the poor quality fuel in the UK.

i'm confused by this now... is it or isn't it real then?

its not real blake, youre too gullible

Did you know that gullible is not in the dictionary?

As I recall, from college days, fuel octane rating was derived from a scale, attached to the side of a variable compression, single-cylinder engine. This was devised by Sir Harry Ricardo, and he investigated the engines performance with varying compression ratios.

He awarded different octane ratings to fuels, depending on their performance when used with his research engine.

So - how does this gizmo "raise octane levels"???

The active fuel molecules (hydrocarbons aka the power) are agitated as they pass past the chemical 'lumps'. This agitation therefore excites the fuel. The excited fuel pushes away from each other thereby increasing the fuel / air mixture (making it more even / less smaller drops of fuel - it also slightly warms the fuel which is a negative side effect). This more mixed fuel is easier to explode therefore making the engine more efficient. As we all know - more fuel = more power therefore ....... thats how these work. Now if you get more power for each unit of fuel, you now don't need as much fuel to maintain a set speed hence more economy.

Obviously the key bit is making sure you've got the most efficient chemical catalyst to promote the most fuel agitation. Get it wrong and you've just got lumps of lead / zinc / what ever in your fuel line.

Considering the wealth of knowledge on here i'm surprised everyone doesn't already know this. If it wasn't for the large fuel companies suppressing this we'd all have them now (think about it, if we fitted these we'd use less fuel therefore they'd make less profit). I know Denso (test / set up engines for major car companies) who i work next too have had a set of engines running these for 6 weeks under various conditions to test performance. The manufacture of the engines suddenly pulled all testing after board level meetings with an 'interested' party in Holland.

Now i'm not going to say any more in case I get in trouble but i'm sure you lot can figure it out

I love irony.

I strongly suspect the origin of these err devices for want of a better term was a British misinformation campaign from WW2.

The story goes in the north African and Mediterranean theatres of operation due to the unavailability of TEL and TML for octane boosting the quality of the aviation fuel was appalling equivalent to pool petrol in the UK ie usually about 80 octane variable from about 78 to 84 octane. This poor quality fuel caused real problems particularly for aircraft and MTBs using the the RR Merlin engine.

As a result the RAF established a factory for reconditioning Merlin engines in Cairo where the problem of exhaust valve burning was solved by a field modification involving the skills of a particularly gifted Arab welder and a large supply of stellite welding rods.

The fuel catalyst story was a cover to throw the Axis intelligence off the scent and so protecting both the maintenance unit and perhaps preventing the Luftwaffe copying the field mod.
