The benefits are not only immediate (which I cannot explain), but also long term.
After more than a year of using it in my Touareg V10 TDi, I started feeling the difference.

Will this 250 work in a Petrol Engine too

2SO = Two stroke oil

Yes, I've been doing it for more than 30 years.

I replied with this post on the post about dirty diesel but I think that my reply belongs here, so here it is.


Before I rebuilt my 3.2 DID engine I was in contact with Chevron about lubricants for the engine, transmission and differentials. They are the manufacturerers of our famous Delo 400 oils. They gave me very good advice and yesterday I sent them the e-mail below (marked in red)

I've got a few questions to ask:

1. Is Delo 400 a low ash oils as needed buy the latest developed diesel enjins with all the latest immision control valves and filters ?

2. Is there any benefit in adding two stroke oil to the diesel of my vehicle ? a. Will it help prevent carbon build-up on the pistons ? b. Will it better the lubrication on the diesel pump ? c. Will it counter the build up of residue due to the PCV ? d. Is all two stroke oils low ash oils ?

They were quick with their response and this is what their response to my e-mail looked like (again maked in red).

Dear Waldo Fourie,

Low ash oils are necessary for the latest vehicles fitted with Diesel Particulate Filters (or 'DPF').
You will also see the term 'Low SAPS' oil and this refers to the Sulphated Ash, Phosphorus and Sulphur, which the latest oils contain less of to enable the use of the DPF as a way to reduce emissions.
In Europe we have Delo 400 LE Synthetic 5W-40 (as well as some low SAPS Ursa grades) and in the USA there is Delo 400 LE 15W-40 and 10W-30, as well as the LE Synthetic 5W-40 grade.


There would be no benefit in adding two-stroke oil to diesel and we would strongly advise against this as it may impair the running of the vehicle.
It would be better to use a diesel system treatment, which would prevent the build up of deposits on the injectors and keeps the fuel system in good operating condition.

Two-stroke oils should always be low-ash as they are 'total loss' lubricants, which are burned with the fuel in the two-cycle stage of the engine and it is important that they do not leave any deposits during the combustion phase.

Hope this information helps.


Best regards
Andrew Moseley.

My next question to them will be: to explain the difference between the Delo we buy in RSA and the Delo mentioned in their answer in their e-mail. I will also asked them if we need the other speck oil or ain't it necesary duo to legislation in ou country.

I will post what ever I hear from them on this forum.

Hi Andrew,

1. Will adding Two Stroke Oil to diesel help to burn away any deposits in the combustion chamber caused by oil used in the crankcase or deposits caused by the diesel (50ppm sulphur) we use in South Africa?

2. What is the main advantages of using diesel with a lower sulphur content? There is two diesels available in South Africa. One with 500ppm sulphur content and one with 50 ppm sulphur content.

Sorry for being such a pain with all my questions.

Waldo Fourie


This is the response I received from Chevron (Marked red):


Hi Waldo,

No, adding two-stroke oil will not help to remove deposits.

I believe that Caltex Diesel with Techron is now available in SA (and Caltex Diesel 50 with Techron D) and using this would help to keep injectors clean and so help to keep combustion deposits to a minimum.
I am not sure if it is available in SA, but there is also a Techron D Concentrate fuel system cleaner, which is added as a treatment into the fuel tank.
Techron has been in use in the USA for some time now and the technology is very good - it has been gradually phased in around Europe.

The reason for the introduction of the lower sulphur fuels was in response to tightening emission regulations and the vehicle manufacturer's were able to plan their new vehicle introductions according to the fuel regulation timelines. A new vehicle would need to use the lower sulphur fuel, whereas older vehicles would still be OK to use the higher sulphur fuel for the time being.


Best regards
Andrew.


With this post I rest my case.

Waldo Fourie

Manufacturers put in EGR systems, develop lower sulphur diesel with less lubricity, use CATs that block, use DPF systems etc. They do this from pressure above in government for regulations etc.

That's not to say that it is the best for the consumer.

Manufacturers can't for legal reasons encourage the use of 2SO or some of the other things owner's perform to their vehicles.

Land Rover doesn't even want to approve an EMS engine monitoring system (which is clearly beneficial to the owner)

If we were to believe everything we get fed from the manufacturers and higher authorities, we'd be nothing more than lemmings.

I prefer to challenge the norm in everything (and sometimes I'm wrong and pay the school fees), but until it's actually proven otherwise I'll still stand by 2SO being better than not.

I started a thread here to get some hard evidence.

80k later using 2stroke oil mix of 200:1

I used to run Delo 400 in my Colt 2.8TDi and traded that in on almost 300 000km without so much as a burp or a hiccup from the motor and I must add that the engine ran noticably quiet for a diesel. I now own a 3.2Di-D SWB Pajero and the first thing I noticed was that the engine is noisier than my 2.8 was. I discovered that the vehicle has been serviced using a fully synthetic Helix HX7. I am considering changing to Delo 400 but I've heard that changing from synthetic to a mineral oil is a no-no. I would also like to start using 2SO (200ml per fill up)to add extra protection for all the upper cylinder moving parts, as mentioned by you wizards here. Am I hijacking this thread? I apologise if I am and can move to a purely Delo 400 discussion if I have offended anyone.

Hi,

As far as I can see there is little/no problems that can arise from using 2SO, but some possible meaningful advantages.

So my question is, how much 2SO do you add? Do you add it with every tank of diesel, or once a month?

Thanks
