I have topped up 3 times now with a JASO Grade FC (300ml added) and see a great difference in mpg. Sat in cruise control at 77mph and the returned average has increased from 30mpg to 33mpg over a 200 mile trip. (approx 10.6 l/100km to 11.7). Did 400 miles plus at the weekend and felt the car was more responsive in 6th and smoother.

For Yamaha Fan - found this 2 stroke in Halfords (Castrol Power1 Scooter 2T JASO Grade FD partial synthetic at £8.49). I have a DPF fitted is this suitable? I seem to remember you advising that a particular engine lube oil as being the best choice for FL2 TD4 but cannot find the thread -can you please direct me as I want to use the best quality at first service in January?

Dave, in my opinion you're right saying "you don't feel it needs it" as - besides of a smoother engine running - it is hardly possible to feel the difference.
All those consumption figures as well are very unreliable as it isn't possible to drive the same distance under exactly the same circumstances. However, the main reason to add two stroke oil is to reduce the risk of increased wear of the injection system, due to the - for "environmental reasons" - modified diesel fuel, and that's something one will find out only after a quite high mileage.

High mileage won't be a problem for me. Car goes back in 18 months and depending on market conditions I'll probably get me a new one  ______________________

Dave, although I do accept your stand, you do not know what you are missing, if you do not try it.
"Thinking, believing or maybe" does not count unless you have experienced the benefits of adding 2-T oil.
I do not work for the oil industry or dealership, I am just a normal user.

YF,

If I was going to keep the car for a long time then I would probably try it and see, but as my FL2 gets handed back to the dealer in 18 months I'd rather keep my money in my pocket.

I do work in the oil industry and at present the company I work for has back-orders totalling over 11 billion dollars.....

The most respected Italian car magazine - Quattroruote - recently published a report after using a Freelander2 for 100.000 km.

After the test the engine was thoroughly checked and some soot was found around the valves that prevented them to work properly. This fact was blamed as the cause of deterioration of performances in the last part of the test (fuel consumption up, max speed down).

After reading their report any residual doubts I had about adding 2T oil immediately dissolved and I take this opportunity to publicly thank YF

Thank you, Mabo, it is cream for my soul after so many critics (and some ignorants).
The German Technical Verification Authority has conducted a very similar test of the Freely 2 TD4 over 100.000 km with similar results: heavy soot deposits on the turbo blades, the outlet valves and the piezo injectors, which has led to reduced power and increased fuel consumption - but no breakdown yet. With the addition of 2-T oil this could have been avoided.

........adding 2T oil to diesel, is like adding flouride to toothpaste or tap water......

Obviously, non flouride toothpaste or water will not harm, but the flouride brings far more benefits compared to potential problems......

That's my rationale anyway !

While there is good reason to expect that the solvents and additives contained in 2T oil may help cleanliness and solubility of dirt in the fuel (yes therefore keeping the valves and injectors clean). Is it not the case that these exact same properties can diminish the lubricity of the of the fuel, a particularly important feature of the fuel when used in modern ultrahigh pressure common rail injection systems. Any decrease in lubricity puts the pump at risk. Stornoway Grey GS ... What a fine motor ... but not any more ... ... psst look at my gallery!
Company cars ... a thing of the past - May 2013.

my understanding is that the 2T oil replaces the lubrication in diesel fuel, that was lost when sulphur was removed from diesel fuel. I think this also explains why the engine sounds quieter after adding the 2T oil.

In addition, because it burns at a much higher temperature than the diesel fuel, it therefore promotes a "clean burn" - meaning cleaner exhaust fumes & much less "soot" build up in the engine, valves & particle filter.

(All this is from YF, who is the expert).

(I think in Germany they dismantled a diesel particle filter - from 2 engines, 1 of which had been using 2T oil. They discoved that it was only about 30% full of soot, compared to the other that was about 80% full). Both engines tested & measured under the same operating conditions of course.............

Yes, I can support Jimmy. 2-T Oil INCREASES the lubricity of ULSD diesel fuel (ULSD = ultra low sulphor diesel), which is only sold in most of Europe for air-pollution reasons.
Sulphor in the diesel has lubricating effects, and removing the sulphor did create technical problems to the high pressure injection system. As bio-diesel has a higher lubricating factor as ULSD, 5% of bio diesel is mixed to the diesel, and the lubricity of todays diesel is better, but still at the minimum level. Adding 2-T Oil will give the diesel the wanted lubricity for long term reliability besides considerable reduction of soot.

Yesterday I ordered 25 l. of mineral 2T oil with JASO TC spec. at 3,65 € / l. VAT incl.

Speaking with the representative of the oil company, I learned that apart from the colour additive there's some other stuff added to domestic fuel. (Unfortunately I forgot it's name ).
The aim of this colourless additive is to make it possible to trace the use of decolourised red fuel, but it also means that if ever there are residues of red colouring agent found in your tank, (it seems to be possible to trace just 1 l. of domestic oil in a full tank), the analysis will proove that it's not because you drove on red diesel.

The colourless additive is SY124 (solvent yellow 124)

A friend drop me the link from another forum and was shocked to see the 2 cycle oil usage really has traveled the world. So to just help out on your 2 cycle oil study over there in the UK... We are doing the same thing over here in the USA.

I've got a huge amount of 2 cycle oil information on my own site to help you...
