I was doing a bit of impulse buying today in the local auto place and saw all these bottles of addatives for diesel fuels, things that sort of - absorb and burn off water in the fuel - stop bacteria - kill fungus - increase mileage - decrease services of injectors etc etc
The vehicle manufacturers and fuel distributors don't seem to say any of it's essential or as far as I know even recommend it, maybe they have a vested interest in not wanting to use it.

Any opinions on this stuff - is any of it essential - can we live and survive in the desert without it ??Carpe Diem

The vested interest lies with the manufacturers of the additives. They do their best to convince us that we need them when we really don't. I've never used any fuel or oil additive and have never had a fuel problem in 40years of motoring.

Mick is that 40 years of diesel motoring ??
I never had a prob in over 40 years with petrol and never used additives. But am now 5 mths into my first diesel. We had a small prob on the recent Kimberley trip when the "water in fuel" warning light came on. Drained filter it into a glass and couldn't see water. The wagon was serviced a couple of days later without probs.
Buying a load of fuel with crap is one thing, but managing own tanks, filters and injectors is good maintainance.
I still don't have the answer to the additives Q. Carpe Diem

A motoring show in Perth called drivetime tv did a review of one of these additives.
It looked pretty impressive to say the least. I'll see if I can source some more info on it and post it up for ya.

sorry but no further details from the drivetime website.
from memory it breaks down the water and crap
so small so it can pass through the system to get
burnt along with the fuel.
they showed an example of it in a jar.
a bit like the nappy san commercial where the dirty water
turns clear before your eyes.

haven't used it so can't really pass judgement

cheers

Hi Cocka,
I use Proma fuel products in both Our Nissan 4.2 Turbo and the Ford Festiva Pocket Rocket. In fact I have used these products for the last 15 yrs and have found them to be of great assistance in that they keep the fuel pumps and lines clean as well as the injector systems. This product also assists with water clean up in fuel as long as it's small amounts. There are two types of fuel additives one for petrol and the other for Deisel.
However if you get a crook lot of fuel no matter how much additive you have the tanks still must be purged of the contaminates. So far in 90k Round Aus etc I have had 2 bad lots of fuel which as always creates probs.
I use a CAV system in the nissan which alows one to visually check the fuel in the glass bowl thus enabling early intervention.

Cocka,
I've used additives when I believed I needed to, mainly when people start turning their headlights on behind me when I hit the go button, they seemed to help a bit but when the root cause of the problem is worn injectors addtives won't fix them. As for water and fungus prevention if you are relying on an additive in my opinion to prevent water getting into the injection system you need something else as well, may be a second filter, I have one and this works a treat for me.
For fungus protection, we have emergency fire pumps at work and we have additives in there to prevent fungus and bacterial growth, these have about a 500 litre capacity in one engine and maybe a couple of 5000 litre tanks in a couple of others, the fuel turn over isn't that great (thank goodness) so we treat and sample every six months to trend the condition, usually the tank is drained and inspected for corrosion every four or five years. With a 4wd the fuel turnover will be pretty quick so you would hope that the bacteria doesn't have to time to get a grip.
Keeping the tank as full as possible helps, reduces the vapour space and the chance of condensation, taking a sample of the fuel in the tank every now and again from the drain would be good.
Hope some of this helps. Keep the shiny side up

Cocka,
I use a product called GO, it's not the cheapest but it works, well it did for me. Can't mention the brand because I'm directly associated with the company and I don't want to be seen to be doing the wrong thing. Keep the shiny side up

I'm pretty sure this is petrol based but FWIW Toyota do have their own brand of injector cleaner that is of course highly recomended.

Hi guys.

I have 2 opposing views here, take your pick.

When I had my turbo fitted I asked the (well established ) diesel injector specialists in Redcliffe W.A. his views on fuel additives for diesel.

His response was, in not so many words, fit filters, change them and let them do their work, and do not let some additive in the fuel 'doctor' the fuel so as to let it through the injectors and thus causing premature failure.

The second opinion was given by a mate who has been servicing heavy plant and marine diesel motors for over 20 years.

His view was, after every service or repair on an engine he added the required amount of additive to the fuel and recommended to the owner to keep it up.

When I asked him "are you after a bit of extra 'cop' on the job?" He replied words to the effect that he has done more work on engines fouled by fuel growth than any other type of work (not counting routine maintenance).

So what would you do?

Regards
