Adding 2 oil stroke in diesel fuel

[ffiill]

I add petrol-and does act as a biocide-use it in car as well in small amounts when very cold as keeps diesel fluid.
If you run on keroscene/central heating oil/paraffin then you will need to add an oil additive to provide the lubrication that diesel naturally has.
Please dont say no-my Merc OM636 workshop manual gives you all the options /alternative fuels.

I add a very small amount of 2stroke (agricultural stuff, in 5l cans, chainsaws for the use of) to the tractors/mule, car, from time to time.


Certainly helps starting, and reduce smokiness at startup.



But I also use red diesel in the tractor....

 

[sarabande]

I looked up the MSDS sheet for Redex.



Naphtha (petroleum), hydrotreated heavy, 60-100%
2-ETHYL HEXYL NITRATE 1-5%
Petroleum naphtha heavy aromatic < 1%
NAPHTHALENE < 1%


So it looks as if it is basic raw petrol before it gets isomerised and treated to become real petrol, with some slippier oilier stuff added, and a cetane improver for better burning of the fuel-air mixture.

So in summary:

The best additive would be some petrol mixed with 2 stroke oil?? Damit, we just changed to a four stroke outboard otherwise we'd always have a few litres of ready mixed stuff to hand

I'm suprissed no one has mentioned adding Acetone to diesel.

Good luck and fair winds.

Add whatever you like it's your engine.

Has anyone added lapping paste to their diesel, it’s about the only thing that hasn’t been added yet. Why add anything to diesel as said on this thread petroleum companies spend a fortune on research and development of fuels for optimum efficiency. Why add anything to an engine that is working perfectly well if it’s not broken don’t touch it.

 

[Lakesailor]

Some people have to mess......

 

[Nostrodamus]

It is called considering your options or tying to extend your knowledge from those more knowledgeable than yourself. I seem to be at the bottom of the knowledge tree so any acorns falling may help.

If the petrol companies had thought of everything we would not have to add biocide and fuel pumps would not fail.

Because the sulphur content in diesel has been reduced in most supplied marine diesel.

 

[SamSalter]

Sulphur content may have been reduced, but your diesel fuel manufacturers may well have added a lubricity agent to compensate.
In N. America we've had ultra low sulphur fuel since about 2001 - not sure of date exactly.
I checked with our Canadian fuel people and they assured me there was an additive put in to counteract the loss of sulphur. I also talked to Yanmar and they said the new ULSD was OK.
I've got a Yanmar 2GM20F and have had no problems with seals and smoke after about 10 years using the ULSD.

If you do a search and/or talk to someone in the know I suspect your British engineers have figured it out too! Engineers know stuff - I are one! They have a lot of training and experience. Or you could post the question on a sailing forum and follow the advice of accountants, bankers and sewing machine salesmen!

Just joking - but as someone said earlier, engine, fuel and oil manufacturers spend a lot of time and money trying to get it right.

I appologise in advance to any sewing machine salesmen out there for lumping them in with accountants and bankers!

slightly "off" topic but diesel related

This is slightly "off" topic but diesel related

I would tend to agree with the above comment regarding fuel companies as I am having a great deal of problems with my Peugeot 2.0 Hdi which has only covered 40,000 miles and still under 3 years old. The engine is stalling when the car is brought to a standstill and the engine cuts out for a split second when accelerating through the gears. It also hesitates momentarily when the cruise control setting is raised by 5 MPH. All of these are intermittent faults.

Why mention fuel companies, well I have been advised by the Peugeot main dealers not to use Sainsbury diesel or any other supermarket brand.

I think others might recommend not listening to rabid bullshit from Peugeot dealers.

 

[Lakesailor]

Try a different dealer or a diesel specialist. The Peugeot engine is well understood by many and is used in a variety of vehicles.
Our Grand Vitara has a Peugeot 16 valve engine. It is also made by other manufacturers and fitted in Ford Focus, 2007 Ford Mondeo, Ford Galaxy, Ford C-Max, Ford S-Max, Volvo C30, Volvo S40, Volvo V50, and PSA cars.

And did it fix it? I suspect not. If it was a problem with fuel all other cars with that engine would be suffering the same problem. Sounds more like problems with the software or elctronic gubbins especially the fact that you say the cruise control affects it.
All fuel in Scotland comes from one refinery and all the tankers get filled from the same tanks. Shell or BP or Esso might add some extra snake oil and charge a bit more at the pumps. But the stuff your supermarket sells will meet the required standards.

And the moral of this story is that Peugeot don’t have a clue what’s wrong with your car and so will blame anyone who is remotely connected with the car namely the fuel supplier, and when the warranty runs out the problem is yours. It is not in the fuel supplier’s interest to sell fuel that does damage to engines it’s just bad for business.

I contributed to the original thread and I continue to use TW3 outboard diesel in my Volvo MD 7b. I use roughly 1%, I just slop some in actually. Engine runs quiet and smooth, starts instantly and blows no smoke.

 

[Javelin]

We had a bad year for diesel in 2011 with a lot of customers having issues with the diesel bug.
We tested our bowser a number of times and sent samples away for analysis so we could be sure of our ground.
During this process we were told in no uncertain terms that there is indeed a significant difference between the fuel sold by Supermarket chains and that sold by Shell, Esso, BP.
The fact that both meet the current regs really makes no odds.
A Fiat Panda and a Range Rover both pass crash tests but I know which I'd rather be in.

The issue, as a yard is concerned is we could choose the "cheaper" fuel and run the risk or take the more expensive fuel and accept the moans due to the price hike.

We took the latter...

 

[Jcorstorphine]

We wait and see

Not sure if it will make any difference as just filled up with fuel from Shell this afternoon and going out for a burn up tomorrow. In fairness to the Pug dealer, they have ordered a new fuel control valve and that will be fitted next week so we wait and see. Also, I have known the Service Manager at the dealer for over 20 years and he does not deal in rabid bullsh/t

Then maybe he is a faithful believer of someone else's.

Do you not perhaps marvel at how your car is apparently the only one in several millions to suffer from suspected supermarket fuel syndrome and that it has never arisen on Watchdog? Is there no question raised in your mind because the problem is intermittent? Is there perhaps some mix ratio of supermarket and designer fuel above which the fault arises, hence it being intermittent?

Sorry but I just don't buy it, although I am happy to buy Tesco diesel since it is my most convenient filling station and my current car has seen little else but that in just over 5 years from new since I bought it. I did have a tail light bulb go mind, maybe that was the cause!
