Fuel Doctor, does it really work?!

Post by jonowong »

I was reading on http://www.fueldoctors.com.au that it cleans your fuel tank and lines of micro ogranisms and fungi...
and gives you a
Dyno tests performed on premium unleaded fuelled V8's have resulted in nominal increases in kW, torque and improvement in air fuel ratios, whilst substantial increases were noted in kW for unleaded fuelled six cylinder engines. Turbo diesel tests resulted in nominal increase in kW and a substantial increase in torque.
they have dyno tests to back up their claims...

but do you guys think?

to me it looks like a "cleaner"...
but correct me if i am wrong but some of their formulae are wrong so from my perspective i wouldn't trust their chemistry

Just the chemistry for diesel fuel is wrong, I guess still works for unleaded.
33O doesnt make sense.
Heheee, cant believe I still got some chemistry knowledge left from high school.

consider the oxidation equation does look like balance out i couldn't be stuff to balance it of course, and since it is oxidation there has to be oxygen lol, i guess what they're trying to proof is sulphuric acid break down fuels ...

hey they sell it in castrol! not that i see a castrol around in any suburbs, and maybe they should explain how to use as well lol

ummm.... no.

It's been a while since I've been at school, but I'm sure oxidation still means the same today. :D

The term oxidation was derived from the effect that was occuring when chemicals where mixed with oxygen, however oxygen does not need to be present for the effect to occur. Oxidation is actually just the name given to the process where one chemical / element loses electrons to another checmical / element.

Getting back on topic...

Deposits build up in every fuel system over time, using good quality fuel and replacing the fuel filters regularly will help to avoid this. It pays to use a fuel cleaner / engine cleaner / injector cleaner from time to time, but it's not going to make a huge difference, it will just help to remove some of the build up.

To further help, stay away from fuels like Optimax which leave a residue in your fuel system. :wink:

By switching fuels (BP Ultimate or Mobil 8000) the residue left behind by the Optimax will wash away after a couple of fill ups.

Use fuel doctor if you like, but you're probably just as well off with something off the shelf at Autobarn.

Remember that the fuel system supplies more than enough fuel to the injectors, so there would have to be major blockages before it started to create any issues. You shouldn't need to use these fuel system cleaners very often. As the need for this is minor and likewise as the difference when done is minor, I generally only do one about once a year (Nulon or Wynns or something like that).

If you want a proper job, get you injector clean, & I guarantee its way better then those "so call" fuel cleaning addictive.

I use to use those cleaning addictive, until I got my injector clean, the guy who clean it say those cleaning addictive didn't do sh*t. After the injector was cleared, there was a noticeable different on fuel economy & performance.

any build up on the injectors will cause the spray pattern to change and adversely affect the way it ignites..

periodically (say once a year or so) i do an inline injector clean... its basically a pressurised bottle that attaches to the fuel rail and cleans the injectors... almost as good as a sonic clean...

UAS do this as an optional part of a service for around 80-100 from memory.

I understand the oxidation factor akumi but their equation doesn't balance out...thats what i mean by "creating" extra oxygen from nothing... :wink:
i agree with Ruchi, by filling your car up a couple of tanks with ultimate will clear the optimax residue(toluene)(spl)...regarding injector cleaners, maybe using a products that others have used would be the safer go....

Optimax leaves a toluene residue behind which takes a little while to flush out.

Use either BP Ultimate or Mobil Synergy 8000 if you want to continue using a 98 RON fuel. A couple of tank-fulls of those will eventually flush out the toluene from Optimax.

Do a search for optimax on this forum and you'll find a lot of interesting info including links to other sites and responses from fuel companies.

hmmmm.... :roll:

You might notice a few issues until the Optimax is flushed out, nothing major, just response issues. Once the Optimax residue has been flushed out you should get better response and better fuel economy. In simple terms the car feels spritlier on BP Ultimate or Mobil 8000.

I just change to BP Unlimited from Optimax as well.
And, I am upset, didnt discovered this fuel before. Instant improvements. Less engine noise, smoother ride for sure, and increase trottle responce.

PS: I have also added a bottle of Nulon Complete Petrol Engine Cleaner (white bottle, should cost around $20) stuff into the tank, with the first full tank of BP Ultimate.

Expensive fuel, but worth it for sure.

I've always used Optimax as well, so it looks I will have to give BP Ulitmate a go.

Is this "toluene" business proven, or just hearsay? Or one fuel company bagging out the other?

And does anyone know what range of price difference between the BP Ultimate and Optimax I should expect in Sydney?
