shepp 2,285 Posted June 2, 2015 Report Share Posted June 2, 2015 Has anybody else tried 2 stroke oil as a diesel additive? I started using it a few months back in my Freelander 2 auto, and have raised my urban fuel consumption from 25mpg to 30mpg. I tried a tank without it and consumption dropped again. It also makes the engine quieter on cold starting and increases performance. Some people have had more success that others but when I first started using it it did take a two or three tanks filled and 2 stroke added to get the fuel consumption down to this level. It is supposed to clean and lubricate the engine during combustion. I add 1/3 of a litre to an empty tank and then fill on top with diesel to get a good mix. I use Comma 2 stroke semi synthetic JASO FD at £8.00 a litre. Apparently semi is better than fully synthetic, but you need to go for something rated at JASO FC or JASO FD, if you do not have a particulate filter you can use cheaper mineral only stuff rated at JASO FB.

tomburras 2,721 Posted June 2, 2015 Report Share Posted June 2, 2015 I gave it a go once only because there was a bottle in the garage and yes it did make it quieter. The best thing I ever did was run my Landy on biodiesel I not put normal diesel in it for 18 months. Cleaned out tank/pipes and runs soo nice on it. Quote Link to post Share on other sites
tomburras 2,721 Posted June 2, 2015 Report Share Posted June 2, 2015 And it's only 80p a litre - if your in Leeds pm me and I'll let you know my supplier so you can get some to it saves a fortune. Quote Link to post Share on other sites
shepp 2,285 Posted June 2, 2015 Author Report Share Posted June 2, 2015 Sounds like a bloody good deal mate. Unfortunately my engine is not supposed to run on it. But my mate has an old Defender and would like to know how he can go about finding a supplier here in SW London / Surrey? Quote Link to post Share on other sites
Rimfireboy! 1,463 Posted June 2, 2015 Report Share Posted June 2, 2015 It works, try 150ml of 2 stroke to 30 litres of diesel. Quote Link to post Share on other sites
the monkey 337 Posted June 2, 2015 Report Share Posted June 2, 2015 tried it in my hiace over 7 tankfulls ...not a scrap of difference Quote Link to post Share on other sites
jocky 198 Posted June 2, 2015 Report Share Posted June 2, 2015 what about when HMRC dip your tank. Quote Link to post Share on other sites
shepp 2,285 Posted June 2, 2015 Author Report Share Posted June 2, 2015 what about when HMRC dip your tank. Because it's such a small amount it is classed as an additive. Quote Link to post Share on other sites
shepp 2,285 Posted June 2, 2015 Author Report Share Posted June 2, 2015 It works, try 150ml of 2 stroke to 30 litres of diesel. It does have mixed results. 1 Quote Link to post Share on other sites
the monkey 337 Posted June 3, 2015 Report Share Posted June 3, 2015 At what dilution does it stop becoming an additive Quote Link to post Share on other sites
smithie 2,429 Posted June 3, 2015 Report Share Posted June 3, 2015 i tried it but not enough to have a valid opinion. i have read that its added to bio to stop fuel pump failers as theres an addative missing in bio that can be found in normal diesel. without the additive the seels fail in the fuel pump. thats why the two stoke, also runs a little hotter burning carbon off ( i think) thus helps with cleaning the engine only read this doesnt mean its correct Quote Link to post Share on other sites
smithie 2,429 Posted June 3, 2015 Report Share Posted June 3, 2015 found this on another forum posted sept 2009to all interested:due to the pollution control measures of the EC diesel-oil is nearly sulphur free and contains up to 5% of bio-diesel. Sulphur has the property to grease the high pressure injection pump and the injectors. Without sulphur, the reduced greasing property of the new diesel has already shown negativ impacts on the long-term stability of the injectors and the high pressure pump. The pump manufacturers have tried to react by lining the moving parts of the pumps with teflon or other suitable material. However, the long term stability is still not achieved as with the old (sulphor contained) diesel.The engine-research centre of a well known German car manufacurer has conducted some long term tests of diesel additives to find out whether any one of them will have an impact on the long term reliability of the diesel engine components. This introduction to explain were my information comes from.The results of this research: any diesel additive of any manufacturer presently on the market is not worth the money!BUT: 2-stroke oil, which we use in our motor saws, lawn mower or in 2-stroke motor engines has shown to have an extreme positive impact on diesel engines, if such 2-stroke oil is added to the diesel in a homoeophatic dosis of 1:200. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease every moving part of the high pressure pump and the injectors.Besides this, the 2-stroke oil will keep the diesel engine clean, as it burnes cleaner as the diesel itself.In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. This proven fact delays the DPF (diesel particulate (soot) filter) to clogg, and the "burn free" process of the DPF will be much less.One more information: in Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongs others, the pollution of petrol and diesel engines.The measured cloud-factor of a diesel engine without use of 2-stroke oil has been 0,95.The same factor with the use of 2-stroke oil has been 0,47 - reduction of nearly half of the soot particles.Besides this, the use of 2-stroke oil in the diesel will increase the milage by 3-5%.and more :-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 flopp 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 advocats 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 homoeophatic 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 poperties if added in a small dosis 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 accademic 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 dosis of 2-stroke oil. The dosis 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.anyone tryed this in there patrol? my mate is using it in his navara and you can tell the difference when you start it up cold. apparenty on the navara site there are a lot of guys using it? be interested if anyone is using it in there patrol Quote Link to post Share on other sites
