Fuel additives

[OmegaV6]

Hi... remember I know nowt about these odd diesel engines ..... this is the first one I've ever had in 40 odd years of petrol head enjoyment !! This is a 3.0 turbo V6 Allroad

Due to the present covid crisis, the beast is getting very few drives, and those that do occur are shortish - max about 15-20 miles, and that is going the long way round to get to the few places I must get to !! otherwise , for health reasons, we simply don't go out.

Everything I read tells me that short trips are bad for most bits of this engine from the Turbo through to the Cat to the DPF .. but I have no choice at the moment.

I am considering using a fuel additive in an attempt to reduce any problems, and the best I seem to find is "Archoil AR6400-D Max Professional" which claims to fix all the problems mentioned.

Question then, for you guys who "know" these things ... is this a "snakeoil" type claim .. or do these additives work ?? Is it likely to cause any damage or other problems to this engine ?? Is there anything else I should know/be aware of before going down this track ??

Regards and stay safe .... E

2 Stroke oil - JASO FB spec .

2-EHN .

[Whippy53]

I've started adding that to my breakfast cereal now.

You are 99.99 percent worrying over nothing, and if something does go wrong (which it wont) it was going to go wrong anyway, lack of use or not.

Pretty much all the fuel additives are snake oil.
The only ones that actually do anything are the fuel stabiliser type used in the leisure boat world, and all they basically do is stop the growth of the fuel bug.

Wifes 3.0tdi has done all of maybe 20 miles in the last 8 weeks, and if it does another 20 miles in the nxt 5 weeks I would be amazed.

[Gazwould]

It's not snake oil when you have your own set of several years worth of Mot smoke opacity test results .

I doubted the accuracy from machine to machine , when in my new ownership the average was 0.02 from the past year somewhere else .

2T alone halved it !

As for 2-EHN it's a bonified Cetane booster and is added to diesel , premium diesel has more supposedly but it's all a con as Cetane number is not disclosed in UK .

And cheaper to add yourself , buy 5L , I add 200ml 2T and 40ml 2- EHN pre made up in multiple used 250ml Redex bottles.

[lynalldiscovery]

Still snake oil until you can prove via reliable results, otherwise it is just your opinion, same as mine, which both mean squat.
Note the makers have very little in the way of quantifiable test results?

There is a thread somewhere, on this forum I think? with a reply from the makers of 2so saying, do not use their product in diesel engines.

[lynalldiscovery]

Ha found it, looked for ages other times and could not find the thread, first search just now and bang there it is!

Like a lot of white papers they are technically flawed , it's studying JASO FC 2 Stroke , those in the know use JASO FB , big base oil difference !!

I have great pleasure of late on debunking a white paper on the drive by wire throttle improver 'Sprint Booster' I've not yet mentioned the huge technical flaw yet , it's very simple but has worldwide been overlooked, similar mistake to this JASO FC 2T technical study .

So why do you think my smoke opacity halved , lol ?

[lynalldiscovery]

Sounds to me like you can solve all the worlds pwoblems all on your own.

[Whippy53]

Yup, provided they can all be solved with a good healthy dollop of 2 stroke. ��

[Gazwould]

You're not wrong , it's all a question of who digs the deepest !

It's almost all theory Vs Real world practical .

Tyre sizes are a prime example..

Not to mention solving the decade old oil debate of 5W-30 504.00 507.00 Vs 5W-40 502.00 505.01 .

Wonder if it could cure covid 19?

Anyway back to the additives.
Sadly for me I have been working on trucks for 3 decades, and in them 3 decades i have seen pretty much every fuel saving device/additive going, remaps/magnets/lpg/cng/mix of gas and derv, and they all have one thing in common, the operators always had loads of issues and went back to straight derv.

Being a sucker I have also tried most of the additives and can say hand on heart apart from a placebo effect once I have never noticed any difference to how the vehicle ran/mpg/emissions etc.

[Gazwould]

That Trump.. disenfectant..idiot.

I drink 2T and 507.00 ( non approved flavour ) to keep Covid 19 away .

5G is also spreading it..

Trouble is I've got multiple hardcore MOT smoke opacity results .

[Whippy53]

Can't argue with hardcore smoke.

Black on black action:biglaugh:

[Gazwould]

No smoke , no poke , lol .

[lynalldiscovery]

That is a pet hate of mine, diesels smoking excessively, soemtime amazed when I see what I would class as recent cars blowing black.
You can get power and no visible smoke, when was the lastt ime you saw a modern ruck making smoke?

I spent ages messing with older diesels trying to get power and minimal smoke, easy when the rpms up, but low to mid rpms and a tadge to much fuel oh dear!

[Gazwould]

The old Ford 1.8 tdci is a Batman car , watch'em smoke as they spool .

2002 VW 1.9 tdi 130 manufacturers vin sticker smoke opacity coefficient 0.60 .


2009 Ford 1.8 tdci (C-max , Focus) 1.75 !

[Whippy53]

Remember, black smokes matter.

Right correct 2so purchased, 200 to 1 ratio, now on 4th tank of fuel with 2so, and as I predicted earlier on no difference to how it starts/drives, if anyhting mpg has taken a 1 mpg dip!

Nah he wouldnt!
I literally drive the same route boring every day and have done for years, I can tell you exactly when/where the car is going to change up and down a gear before it does it.
I work odd shifts and the roads are normally quiet, so apart from the weather not much changes day to day
I can say hand on heart it is no different to how it starts/runs and drives on straight derv.

[Gazwould]

This is true with newer cars particularly those with balancer shafts or smooth V6 .

[A8Cruiser]

I think most of the time, smokey diesels mean the air filter is dirty/clogged.

Fuel wise, Shell V-Power to clean the injectors etc.

personally, I only use Shell diesel.

[Gazwould]

That be the Premium Diesel con....kinda reminds me of the amazingly successful false marketing of performance K&N air filters .

[A8Cruiser]

I use the normal Shell diesel.

Shell petrol got my old Senator starting first time everytime with no churn. Any other fuel and it would start first time, but would churn for 5-10 seconds before firing up. So, Shell everytime for me. :biglaugh:

Hi,
Don't know if this is any help. I have been using Redex for years every time I fill up with diesel. half a bottle to usually 3/4 tank of diesel in my old 2.0 Passat. I had never any issues with injectors and done over 280,000 miles on it. I had to take the engine out (200,000 miles) and in the process had to remove the ERG. It was completely carbon free. I saw my mates ERG which he had to get cleaned and it was bunged up after 100.000 miles. Was it the Redex? I wait till Tesco's do it for half price and buy a pack of it £2 a bottle. They also co DPF cleaner for £4 (half price) and I dump it in now again.
