fuel diamond, tablet , any good , or a gimmick

saw a guy demonstrating at a local bike show, last month.
these are a diamond shaped piece of metal about 2" long, in a plastic "matrix" sleeve, supposed to take care of the E10 fuel now on sale here, without the metal deteriorating, heres a description.

Description
The fuel diamond is very simple to use, simply drop the fuel diamond into your petrol tank via the filler.

The fuel diamond reduces the risk of the petrol in your fuel tank going stale over winter lay offs infact if you have a car or motor cycle that you do not often refuel due to little use the fuel diamond would be ideal for you to use.

• It stops the what can be a rapid drop in octane.
• It stops the change in fuel colour.
• It stops emulsification.

If fuel becomes stale in your tank it can make starting difficult it can block fuel lines carb jets fuel pumps etc.

Now theres is no need to drain your fuel tank during lay offs which can allow moisture to enter the tank and fuel system.

The fuel diamond is guaranteed for 5 years it will treat a fuel tank of up to 60 litres refill after refill after refill.

If your fuel tank is larger than 60 litres simply put more than one fuel diamond in your fuel tank.

FUEL DIAMOND



has anyone tried these ,with any benefit, or are they just a "non disprovable" gimmick

 

Stabil works great and you can get it virtually everywhere and I know how it works think I will stick with what I know works . Sorry skeptical of this diamond .

 

Mate, have you had a blow to the head? This reeks of snake oil.

 

Fuel Diamond

 

Without and science to back it up I call BS. Just watched a guy on youtube put it in cycle but also gave no reason other then a friend of his does it. I guess I could be wrong, but jumping off a bridge because the person in front of you did it just does not give me a warm feeling.

Not meaning to hurt anyone's feeling, if you are using the product and can show me/us why it woulds I am more then willing to listen/watch.

 

yep ,i agree, but can anyone give us any reason that Stabil is any different,

 

i guess the argument would be the cost of the diamond which should last 5 years
its the 1 size fits all that turns me away from thinking about it .

would like to know what metals are in it, read silver which turns water to a white powder and manganeese or magnesium is part of the mixture.

it would be easier to do the water in the fuel to remove the ethonol from the fuel

Removing ethanol from gas - YouTube

 

I wouldn't bother with that either.. Started my 550 after a year lay up in a cold shed with a tank 3/4 full. Stabil instructions state tank must be 95% full which is where (most of) the benefit comes from.
If you block off the breather too then less chance of damp air getting in and condensing. IMHO.

 

My guess would be that the fuel diamond tablet is made of some type of sacrificial metal so it will oxidize from the water absorbed by ethanol rather than the tank and other parts of the fuel system. I couldn't find anything on the internet about what it is made of I'm also assuming no one else found anything either.

BTW I'm sure most of you have seen Ryan on YouTube. Here is a rather entertaining segment about fuel additives.

If this works and it changes something in the tank....what happens to what it changes? Does it sink to bottom of tank? Does it change to air and leave the tank? Is is sucked into the engine and then burned?

Will stick to known solutions like in the video post above.

 

Hmm, gonna try some logical thinking here. most of the concerns around ethanol are its affinity to water which can later result in 'phase separation' whereby the ethanol water mix drops out of the solution plus any further water
entering the system will be displaced to the bottom of the tank. BUT how is this worse that 0% ethanol fuel where ALL water introduced into the system (e.g. via condensation on the inside of a partially full tank) will sink to the bottom.

In either case by limiting the amount of 'empty space' in the tank (filling it up) and sealing off any breathers to prevent the circulation of moist air into the tank you will limit precipitation and hopefully in the case of E10 it will be below the 0.5% by volume it can absorb. So in a 15 liter tank - 75ml of water - which is actually quite a lot.
