engine additives,diesel

[bigdom1957]

hi ive bought myself a c class 2015 plate 18k on the clock , ive been reading quite a lot of posts where people are talking out dpf and rgf ,basicle the particulate filter and refenitive filter, and accociated problems of them and maybe down to the way people drive there cars , would it not be a safe thing every year at least or maybe twice putting a cleaner in the tank to help this from happening. i know theres a lot of additives out there but its only a suggestion ,im sure theres some boffin out there that knows best , and will give advice if its good or not , ie when i had a petrol car i put it in twice a year and could feel the differrance . im not up to date with diesels.

 

[KennyN]

I do around 4k miles per year in my diesel CLS , i have only put an additive (Forte DPF cleaner) in once in four years of ownership, the car always get V Power Nitro and i have not had any issues at all with the DPF.

My journeys consist on 2.5 miles to and from work with minimal sustained motorway miles to clean the filter , when the regen process starts i give it 20 mins in forth at 70 mph just to complete the process.

There are loads of DPF horror stories out there , but some are just that , stories.

Well you could use a synthetic two stroke oil,about £15 for 5 litres,I have used it in the past,I used a old redex bottle and decanted it from the 5 litre tin,used it every second time I put in 70 litres in the car,it is far cheaper than buying these brand names,it does help with keeping the engine clean.

Two stroke oil ? not heard that one. Two stroke oil is designed not to burn (most of it), but to cool and lubricate the bearings and wear surfaces in a two stroke engine and the get shot out of the exhaust along with the exhaust gas.

How will that help a DPF ? Not saying you are not getting a result. Just curious.

 

[Tuercas viejas]

DO NOT
Put two stroke oil in a diesel engine equipped with a DPF & SOC Cat, this will plug it up.
Also be super careful of what you put in the tank.
Some additives are just alcohol based (read old technology) and some have lead.
Lead by the way will poison a Cat either petrol or SOC diesel .

MB like most manufactures don't recommend additives for many reasons, but something like BG 245 is formulated for actual remedies in a can.

[PobodY]

Lead shouldn't do anything to a DPF, but I agree that it will kill a petrol catalyst, SOC, or LNT.

 

[Tuercas viejas]

Yes but do remember on a Bluey (I call Blurrtech) like a Sprinter the Cat & DPF are all in one!
Again caution.

The 2 stroke oil you see reccomended as a fuel additive is the marine TCW3 spec and ashless. I've used it as a petrol additive in the ratio 1:640 on an old motorcycle for many years and it does clean up the combustion chambers. Even though it's supposed to be ashless I've fought shy of ever trying it on an engine with a cat.

Three tankfulls of Shell VPower Diesel will do a decent job of cleaning up deposits in the injectors. Thereafter, I'd suggest running on regular diesel from one of the major fuel suppliers (e.g. Shell, BP, Esso).

Don't put 2-stroke oil in your diesel.

 

[Trickythemerc]

I use Forte advanced fuel treatment once a year and drop an engine flush in every other oil change, if I am doing one of my Aberdeen, Inverness runs I fill up with Shell VPower.

 

[grober]

Anything that raises the cetane rating of the fuel is a good idea if you run on "cooking/supermarket" diesel. Wasted if you use the better stuff already . https://en.wikipedia.org/wiki/Cetane_number

Millers also do a DPF clean up product- no idea if its any good or not??

I've been running my Phaeton and vans on the Hydra Fuels cetane booster and injection cleaner for about a year now.
In the past I ran the Phaeton on Shell V-Power diesel all of the time and my vans every forth fill with V-Power diesel.
I have not noticed any difference in the Phaeton since changing over but I have saved a few quid buying ordinary diesel rather than V-Power diesel.
If you have the time to inject the additives no problem otherwise I'd run any diesel on V-Power diesel just purely for the cleaning capabilities of the fuel.
For the record I buy my diesel vans new and run them for 180-200,000 miles then throw them away and I've never had issues with MOT's or injector problems if that is anything to go by.

Had mine when it was just 2.5yrs old and always ran it on BP ultimate or shell v power but have had one injector changed @99000 Miles and i expect i could have another one thats 'not within' spec. went for the 350 instead of the 250 due to the injector problems but over the approx 5 years and aprox 80,000 miles its only had thermostat, glow plug module and one injector

 

[CowleyStJames]

Don't put any additives in my 2011 E250, just run on Shell V Power. That and a remap, it runs sweet.

 

[grimree]

Nothing to do with additives - but I used to fill my SLK 250 CDi with BP ultimate diesel, got about 41 mpg (mixed driving), the main dealer said it was a waste of money so I started using regular diesel - my mileage went up to 44 mpg - go figure?

how do you know when the regen starts , thought it just did it under cover no lights or anything , are we on the same page .

I confess that I get irritated by the fact that some fuels are better than others. Whatever it is that makes the premium fuel better should be mandated across all fuels. Fuel whether petrol or diesel already has to meet a defined specification but there must be something missing in that spec. if the premium stuff works so much better.

For example some profess the need for a lubricity additive in the form of two stroke oil for diesel to make up for the loss of lubricity that occurred when sulphur levels were reduced and yet 350 ppm lubricity additive has been mandated since the year 2000. If 350 ppm isn't enough why don't they increase it.

We often hear that all or at least most fuels come from the same refinery and that the differentiator is the additive pack which is only put in at the point of transfer into the road tanker. It's easy to assume one additive pack is better than another and that's the reason it's only put in at the last minute but I've been reading that there are other reasons. One is to avoid contamination of the pipework used for other fuel specs and another is the polar nature of the additives (they are attracted to metal surfaces) means the additive could be partially used up in the refinery pipework if it wasn't added at the last minute.

I have used 2T in my Shell Nitro diesel fuel for almost 3 yrs .......i have the 926 EXHAUST GAS CLEANING WITH EURO 4 TECHNOLOGY with the DPF in the CAT.
The engine runs smoother is a lot quieter even on cold start gives no black smoke out the back on acceleration and seems to give more economy.
I go to France quite regularly and the French diesel is not quite the same as in the UK.
Semi Synth is the one to use conforms to JASO FC or ISO.....L-EGC or EGD Low Ash.
I have mixed Fully Synth with Semi as i found some for sale in Germany at around £15 for 5 litres and no problems at all. The reason they say not Fully Synth is only because of it`s price.

Here is a quotation from an article which includes some text from a Mercedes article:

Two stroke and Diesel


You may all know that Mercedes Benz have conducted in 2007 a long distance reliability test with a number of Mercedes E-Class 320 cdi from Paris to Beijing. Due to the fact that the diesel quality in East European Countries, Russia and China does not meet the DIN requirements, and Mercedes did not want to take the risk of their engines to flop due to lousy fuel, the total tour has been accompanied by diesel tanks to re-fuel the E-Class cdi's. Selected members of the Mercedes clientele could apply to participate in selected parts of this test-tour, and advocates and notaries had to certify the correctness of this long term reliability test.
Although Mercedes does not like it published or made public, it is a fact that the diesel-fuel used for this test did contain 2-stroke oil to grease the high pressure pump components and to keep the engines clean during this marathon.
Why our car manufacturers do not officially allow the homoeopathic addition of 2-stroke oil to the diesel fuel has many reasons, mostly of legal nature. Besides this, which car manufacturer has any interest in excessive reliability of their engines? Their repair shops will have great problems.
Meanwhile the "2-stroke-oil to diesel" issue has attracted the interest of a number of Universities in Germany, as this 2-stroke oil has shown to have amazing properties if added in a small dose to diesel fuel (1:200), especially the positive impact on air pollution, reduced fuel consumption and improved long term reliability of the diesel engine. The pro and con discussions will go on for a while. But as soon as an academic report has been published by one of our Universities, this will change very fast.
By the way: all car manufacturers reject the addition of any fuel "additive" in their cars, and warn that guarantee MAY be affected. Nobody says, that guarantee WILL be rejected. 2-stroke oil in its properties is not an additive, as you add oil to oil if you "dope" you fuel with a dose of 2-stroke oil. The dose of 2-stroke oil in your diesel-fuel is very difficult to analyse, as every (chemical) analysis has the main function to identify substances which are harmful. But 2-stroke oil has proven not to be harmful at all, on the contrary!
Personally, I use 2-stroke oil now for many years in all of my diesel cars (my present business car is a Mercedes 320 cdi DPF Automatic). And I never had any problems whatsoever.
nb:

One quick addition: if we speak of 2-stroke oil to be added to the diesel fuel it MUST be a 2-stroke oil of low ash content, such as Liquid Moly No. 1052 (1 liter bottle) or Meguin semi synthetic. NEVER use fully synthetic 2-stroke oil, besides the cost). 2-stroke oil has very similar chemical properties as diesel oil, and this is the reason why diesel and 2-stroke oil do not mix but compound (if I have used the right word). Once diesel and 2-stroke oil have chemically compounded, you cannot separate them again.
2-stroke oil will increase the OZ-value (Octane) of diesel oil by 3 to 5 points (OZ=x*OZ("2-T oil) + (1-x)* OZ (diesel fuel)). 2-stroke oil does not contain any Zinc-components, and metal-organic additives are virtually absent. This is the main reason why 2-stroke oil burns cleaner than diesel oil.
You can (theoretically) run a diesel engine with 100% 2-stroke oil with no harm. Behind closed doors tests of reputed car manufacturers have shown that a dose of 1:200 is the quantity of 2-stroke oil to be added to the diesel fuel to achieve the wanted results. I have personally witnessed the running in of re-build/repaired diesel engines with a dose of 1 litre of 2-stroke oil in the fuel to be mechanically on the safe side.

mine is relegated to school run duties monday to friday - 4 miles round trip. But knowing the issues this could cause I give it some beans over the weekend or whenever I go on longer trips. Sport mode helps the raise the temperature quicker.

Very interesting, I'll try this straight away.
