Diesel additives..... Fyrex Ci ?

[Ivo]

Has anybody used this stuff? http://www.4wdworld.com.au/products/fyrex/index.htm

It seems that you can buy diesel with it already added at Total brand servos..... http://www.superdiesel.com.au/PR/index.htm

I was thinking of buying a bottle and trying it out, but if someone has already tried it for no benefit I will save my coin.

no, i havent tried it.

From the website :

"DIESEL FUEL ADDITIVE

Fyrex® CI is an ashless organic fuel additive which does not contain minerals, metals or alcohol.

Using Fyrex® CI as directed also:

* Reduces hydrocarbon and carbon monoxide emissions
* Cleans up dirty engines
* Keeps new engines clean
* Reduces engine wear
* Reduces soot loading in engine oils
* Reduces filter plugging, heavy cylinder head sludge, abrasive polishing wear and oil thickening
* Improves fuel economy 4 - 7%
* Reduces engine noise up to 15%
* Reduces black smoke up to 24.5%
* Improves engine start up
* Better driveability
* Faster acceleration
* More power
* Reduces injector and valve deposits
* Exceptional lubricity"

Sounds a lot like firepower pills. Im guessing they not going to tell us what it is. Sounds like bio except for the improved fuel economy ...

Like all "additives" the effect seems to be stuff all unless you've an older engine that needs a clean. Funny that they don't mention the fuel "bug" or algae in the tank, which is the only thing that concerns me really.

It's actually a fungus, Doc... Not an alga. It grows in the tank and produces a black sludge which is the fruiting body of the fungus. This gets dislodged and then is drawn into the fuel lines eventually blocking the filter and stopping the car. I had an episode of this back in the 80's in Perth and it took me a while to work out what was causing the problem. Eventually I cut open a stuffed fuel filter of my GLD and found it absolutely clogged with black goo. I dropped out the tank and had it flushed things were so bad. After that I used a fuel conditioner (if I remember correctly, "Wynns") and the problem didn't recur. This fungus is always around and usually the contamination gets into your vehicle from a poorly maintained servo. Yet again....a good reason to use fast-moving servos, change filters regularly and not to let your tank get low.

One of the experts on the BP Ultimate forum mentioned draining water off the bottom of the fuel tank regularly (?6monthly) as a means of algae prevention. I thought the water trap was on the fuel filter.

I was reading the Diesel Power label at a local auto accessories store. It does have a biocide added as well as injector cleaner; lubricity additive but doesn't mention cetane boost.

There is absolutely no doubt that additives in fuels DO make a difference. Don't ever accept an argument that they do nothing, for it has to be wrong.

Sometimes there is a benefit sometimes not, and clearly the quantity of additive makes a difference.

If you add algae to your fuel, it will contaminate your filters and could wreck the diesel pump, injectors and even the engine.

If you add petrol to your diesel, a little bit won't hurt, a lot will.

If you add acetone, same thing

If you forget to add oil to your 2 stroke fuel, will your engine notice?

And so on.

Fyrex CI does contain a cetane improver and biocide amongst other things.

An all ORGANIC cetane improver
(No mineral, metals or alcohols)

Detergent
(Injector Cleaner for optimum spray
patterns)

Upper Cylinder lubricity agent
(replaces the losses from low
sulphur level)

Fuel stability additive
(rust inhibitor)

Surfactant
(Stabilized fuel drops for better burn
and more atomized spray)

Biocide
(Kills algae and diesel Bug)

Demulsifier
(prevents water emulsifying in your
diesel and adversely effecting your
diesel combustion)

I tried some Fyrex CI, seems to be the goods - mixed at 1000:1, so it is cheap for what it does.

Hi Engine ear.
Maybe you could tell us about yourself ?.
Your location ?.
How long you have been using the additive ?.
The results you have noticed ?.
what car you added it to ?.
Do you work for the company ?.

Thanks in advance.
