Question for Yamaha Fan,

I have added two stroke oil to the fuel twice and although it feels smoother the decrease in consumption appears to be minimul .I do not mind this as I am sure it will improve as the engine loosens up (only done 7k miles but have chaned engine oil for higher specification Morris of Shrewsbury product. If its good enough for Bentley it must be OK).
Question is though the car is only used every two weeks for officiating on forest car rallys when it does get a good mileage in (300 plus in a day) but in between it is parked up so will the two stroke oil in the fuel settle out and if it does what long term effect may this have?

Sorry Bill, I have been on vacation and did not have access to the internet.
To answer your query: 2-T oil added to the diesel fuel will emulgate with the diesel and will not seperate again, even if stored for years. With regard to improvement of fuel consumption it will be less noticable on TD4 engines without DPF, but 0,1 to 0,2 l/100 km should be achieved after proper running-in of the engine.

they picked this thread up over on RRSport

Sounds like they are getting some good results with the mpg too

I happened to mention this idea (adding two stroke to diesel) to my dealership service manager. He was horrified ....... and thought owners who tried it were taking unnecessary risks!

Sorry YF .... I explained that you appear to be an oil expert ..... he was not convinced.

I know nothing about oil, and had felt persuaded ...... now I'm just risk averse!

Yes of course Npinks. However he is both friendly, experienced and knowledgeable and not a "yes man", and he seemed genuinely shocked and concerned for any who have tried this tip!

I also note your use of the future conditional, in your response!! So I assume you also have some reservations?

i have no concerns about doing it

I just think if a car needed it it would already be in the fuel, (but i still understand the benefits as outlined by YF)

Too much messing about in my work suit, measuring in 300ml and then filling up is not something i can be bothered with

Hi Nick,
the reaction of your (otherwise good and experienced) dealer/workshop to the question of adding 2-t oil to the diesel fuel is normal and does not surprise me. It is, whowever, shocking to learn and to see as to how "uneducated" many so called "experts" are if it comes to questions outside their normal scope of day to day workshop routine.
Adding 2-T oil to the diesel is done now for many years, particularely after the available diesel has changed to "ulsd" - ultra low sulphor diesel for air pollution reasons. It is a matter of fact that sulphor in the diesel has a greasing effect to keep the high pressure pump and the injectors going. "Inventors" of adding of 2-T oil to the diesel has originally been the army, and later practised by the taxi drivers, who had to rely on their engines and related peripherie. Meanwhile even Universities have conducted long term tests on this issue with very positive results. You may read the results of the study in the book " Neccessity of additives to ULSD" by Prof. Dr. Mairing, University of Darmstadt.
It is further disturbing that the so called "experts" of our Land Rover work shops do accept without applying any sense the Land Rover motor oil recommendation according to the Ford norm 913 B , so called B1 oils, oils of the lowest possible quality. the Ford norm 913 B has been established in 1998 and does not appreciate the vast improvement in motor oil developments with regard to long term stability and low fuel consumption as laid down by the Eurepean Automobile Association ACEA.
Ask your work shop if they have ever questioned the motor oil recommendation of Land Rover for our Freely 2, and why Land Rover does not follow the ACEA motor oil classification as all other European car manufacturers do.

Fully agree with YF, in relation to the "experts".

My TD4 FL2 (with dpf) goes in for its 1st service soon. I asked the Dealer about the replacement engine oil they would use - and they advised Castrol Magnatec. This has the lowest specification rating possible. They also mentioned I could choose from 2 more alternatives - but I could not even find any info about them on the manufactures websites - they were so old. Needless to say, he agreed that I can take my own oil.

I've added 2T oil to the diesel from new, now done 20,000 km - the engine is smooth & quiet compared to a guy's FL2 that I meet at the fishing club. We position them side by side - switch on the engines - and listen to hear which makes the most noise. Not very scientific - but the result is always the same
