Hmmmmm what's ATF please

Hmmmmm what's ATF please

Automatic Transmission Fluid (aka 'automatic gear oil' although it is not actually oil but hydraulic fluid)

It isn't safe to assume though, is it.

For a start, if you ran ATF through a petrol engine you'd coat the spark plugs with deposits of gunge.

So then you'd have to buy new spark plugs. Hardly a good idea.

why would this happen?

it doesn't happen in a 2 stroke (petrol) engine.

I do believe the OP was on about a four pot petrol.

I have been using Redex for many many years and I strongly believe in the product (I remember it when I was a kid, and that was many moons ago!). I also believe that similar products from other manufacturers e.g. STP, Forte, etc are equally good.

My experience is that Redex cleans the fuel system very very well. A few years ago I took-off the injector rail from a car that did 40k with Redex added to every tankful, and the injectors were all shiny metal and squeaky clean, no deposits or brown spots.

When I bought the Merc, I read in the owner's manual that fuel additive are not recommend. I then found an MB technical document stating that adding additives to fuel is not recommended but use of fuel that already has additives is highly recommended. I suppose the MB engineers do not trust owners to add the right additive in the right concentration... (and looking at some of the comment made in this thread so far it seems that MB may have a point )

Since getting the Merc I only use 'super-fuels', e.g. BP Ultimate and Shell Optimax/V-Power. I am not looking for any mpg or bhp gains, just for the benefits from the additives and detergents while keeping the manufacturer's warranty....

As for mpg and bhp.... I don't think that the higher octane of super-fuels will have any immediate benefits for my engine (a lowly 180K...), but I do believe that the engine will keep it's original mpg and bhp spec over the years as opposed to other vehicels running on plain fuel where performance may deteriorate over time.

HTH....

which will have spark plugs, which ringway said would get gummed up and have to be replaced.

2 pot, 4 pot, 2 stroke, 4 stroke, all petrol and spark ignition.

Found the MB document.... it says:

'The fuel additive should be made available to the customer at the filling station; we reject the idea of allowing the customer to carry out the additive process on his/her own because this would rule out the possibility of guaranteeing that the additive was technically in order and appropriate for the fuel grade concerned.'

The grammar is a bit awkward, but I suppose it makes more sense in German...

Fm iscaboy.

But Ringway did not say put ATF in a petrol engine. iscaboy did.

 

[markjay]

And they say it even more clearly in this doc:

I would go along with markjay and say that using quality branded fuel is sufficient, without he need for additional additives.

additional additives can cause the premature expiration of the cats.

Thanks for everyones opinions/replys,in case it wasn't clear enough on my op the car is a v6 320 petrol & judging by the feedback i think filling up with v-power(or it's new equivalent)every 3rd or 4th tank should have the desired effect,thanks again.

why would this happen?

it doesn't happen in a 2 stroke (petrol) engine.

Because 2 stroke oil has a low or zero ash content.

Sticking ATF into an older diesel is not an issue, but doing so with an EU4 or EU5 diesel engine will lead to a world of pain.

If you consider they require low ash engine oils (the MB229.31 or .51 spec) bunging in something that is stuffed with friction modifiers, anti wear additives, anti oxidants and detergents to name but a few, none designed for a combustion process, is nuts.

Putting into petrol poses similar although somewhat less critical issues because they do not have DPF's but sort of make up for it in terms of risk of killing the Oxygen sensor through silicon contamination, which arises through combustion of the anti foaming additives which are also a key additive of ATF(there was a spate of dead sensors a while back but owing to minor diesel contamination of petrol in the supply chain)

Stick to injector cleaners designed for the purpose!

(BTW, if you do stick petrol in a diesel, after draining the tank (or even not if it is a very small amount) a litre of ash-free two stroke oil in the tank will go a long way to reducing any problems until it works through)

Try this BG 44 K it's meant to be the nuts - available for petrol & diesel engines:

Power Enhancer | BG 44K | Power Enhancer | BG Products

They are giving this stuff away for £1 when you get your aircon gassed at Kwick Fit as a promo.

If only i had aircon ! A friend of mine just had his X5 serviced and they used this product, he'd never heard of it before but said it has improved his fuel economy.

I'll certainly be getting some for the CE.

"This core ingredient of BG cleaners, PEA (Polyether-amine) is proven and documented by the Worldwide Fuel Charter to be the only chemistry proven to safely remove carbon from within a combustion engine. Providing the recommend dosages are not seriously abused our cleaners are no more dangerous than putting gasoline (or diesel for diesel engines) in the fuel tank."


"PEA" is Chevron Techron...much less expensive then the BG product and is approved by Merc and BMW as a fuel additive....
