Any red dye in a tank of fuel is detectable by the sampler the DOT uses, even when diluted by a large quantity of undyed fuel. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. This first test had fuel dosed with zinc at 1ppm (parts per million) and contained none of the detergents that regular diesel contains. The process by which sulphur is reduced in fuel is known as, and take a breath, hydrodesulferization (HDS). But it’s at this point where those mates of yours left the room when the talk on ULSD was being given. Toyota HiLux Surf kzn185 3.0L . Because zinc build-up can break off with fuel flow and thermal contraction (cool down) the engine was stopped after eight hours of running and allowed to cool down. I wonder if there is a dispenser simular to the old Redex ones that used to be on garage forecourts that could be used to make the addition of oil to the fuel tank simple and accurate. DO NOT ADD TWO STROKE OIL TO YOUR TRUCK WHEN YOU HAVE DPF … This latter test is intended to determine the point at which boundary lubrication fails (or the fuel’s ability to wall wet of, say, piston rings), while the HFRR test is a better measurement for wear and tear. Think of it as wrapping the metal bits in a soft blanket to keep them safe. It’s also designed to burn clean so potentially using this again shouldn’t result in any more smoke....it’s just ‘how much’ to use. There has been some healthy debate recently on forums around the web about adding 2 stroke oil to diesel fuel. Scoob, May 29, 2013. Now I have finished the bottle of Millers, I am tempted to try using 2-stroke oil in with the diesel. It’s suggested that if the HFRR wear scar diameter is less than 460 microns, the fuel will perform satisfactorily in an engine. All Rights Reserved. So basically if you put 20 gallons of fuel in you need 20 ounces of oil. Triv Senior Member. Diesel fuel in africa has nothing to do with what we have here. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease every moving part of the high pressure pump and the injectors. Together, though, the results tell an interesting story. It’s about now, I reckon, that the keyboard warriors will be reading this and going, oi oi, fuel company sponsoring research, hmmm. The size of the wear scar (in microns) is directly associated with the lubrication qualities of the fuel being tested. Note: If your vehicle experiences low temperature waxing issues, consider using different diesel brands or diesel with lower bio-diesel content. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. The data, therefore, is meaningful because every … I talked to power service tech guy and he said diesel kleen can be mixed three times what the back of the bottle says ill try 16oz of diesel kleen and 16oz of two stroke … A test conducted in South Africa utilised both the High Frequency Reciprocating Rig (HFFR) and the Scuffing Load Ball-on-Cylinder Lubricity Evaluator (SLBOCLE). The manual also goes on to say that bio-diesel can degrade quicker than regular diesel when stored for long periods of time or when exposed to warm and/or humid weather. i run 2 stroke oil in older diesels frequently they were designed for fuel with higher sulfur the new low sulfur fuels are dryer (less lubrication) i have noted very positive results with 2 stroke oil in older motors and its cheap, buy mine at walmart in gallon jugs as well. Supposed to help with lubricating the fuel system. It also needs to be low ash version too. Thanks, Your email address will not be published. Some will say that because of how hot a diesel engine burns running, say, JASO-FC 2-stroke might not help with lubricity, but it will help remove carbon deposits. And, as we all know, carbon deposits (as a by-product of the fuel burning process) can sap power and see a diesel engine use more fuel because it’s all gunked up and struggling. That said, the Australia Government is looking into the introduction of B20 or, at least working on an acceptable framework, and reckons that bi-diesel could power around six per cent of all diesel vehicles here by 2030. So, you could argue that it doesn’t really help or hinder…but, for me, I wouldn’t bother wasting the extra money on a bottle of 2-stroke to tip into my diesel. That’s why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. So, there’s no power benefit from adding 2-stroke, but that’s not the claim by the Interweb. Next Last. There has been some healthy debate recently on forums around the web about adding 2 stroke oil to diesel fuel. So with this in mind, I added a small amount of 2 stroke oil to the diesel fuel in a 250:1 ratio, and took the landy for a 30 mile drive. Dimer acids were subsequently banned from use. Your email address will not be published. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines.. Like you trying to run a race with a blocked nose. It was invented by Hugo Güldner [ de] in 1899. To the point where some, well, lots of people actually, suggest tipping a snifter of 2-stroke oil into your fuel tank every time you fill up to return some lubrication to the diesel. from what I can tell nobody recommends it other than forums not fuel companies or car … This article never set out to explore the use of fuel additives, boosters or cleaners (because we all know corrosion inhibitors and bug and algae killers in diesel work), rather it was aimed at the idea that adding 2-stroke oil to your diesel will improve the lubricity. It will typically give a slight gain of 1-2 MPG and may even give about 10-20 HP gain if mixed properly. Some claim different types of injectors make it okay to use 2-stroke, others claim it makes engines quieter and saves fuel. Occasionally, some will argue that adding 2-stroke oil to diesel will improve the Cetane number (Octane rating for diesel) but according to the SASOL test it was actually ever-so-slightly less. All diesel sold in Australia, the US, Japan, and Europe must adhere to stringent guidelines on the chemical structure, if you like (for reference the diesel run here and in many other countries is known as EN590). Knowing that 2 cycle oil is lubricating your entire system compared to using a harsh solvent (that thins the lubricants) to breakdown the wax of diesel to keep the fuel flowing. DOMINATOR does an outstanding job protecting high-performance engines. The paper was published by one of the company’s engineers, Adrian Velaers, at the 11th International Tribology Conference in South Africa in 2015. Page 2 ... Used motor oil and 2-cycle oil were tested at a rationally chosen ratio of 200:1. After all, I run it on filtered vegetable oil, so 2 stroke shouldn’t do much harm! Fuel companies have upped their game when it comes to lubricity additives in ULSD. So, go ahead and keep using it if you feel you need to, but just know that adding 2-stroke oil to your fuel tank is doing absolutely nothing for your vehicle and will likely end up increasing injector fouling. Mar 14, 2013 #1 There's a lot of talk on the X type forum about the benefits of adding cheap 2 stroke oil (approx 200ml) … And it turns out it doesn’t. Vehicle manufacturers and fuel … The main reason is that the sulphur from the exhaust pipe forms sulphuric … Hmmm. The fuels tested (EN590) align with those sold in Australia (the relevant specifications are DSEWPaC 2009). The former is considered as the industry standard measurement for lubricity. Nope. This field is for validation purposes and should be left unchanged. 2 Stroke Oil in Diesel Fuel Discussion in 'Trucks [ Eighteen Wheelers ]' started by 217flatbedr, Jan 22, 2013. Don't do it. So, strap in, take off the tin foil hat and get ready to have your mind blown as the things you thought you knew are completely upended. The build-up of zinc on injectors is bad enough, but the deposits that do breakoff during cold starts will eventually make their way to the DPF where they’ll deposit as ash and won’t be burned off. The conclusion drawn was, “There is no technical reason for trace amounts of a light lubricating oil to materially change the ignition characteristics of diesel. So, as countries began clamping down on tailpipe emissions, reducing the amount of sulphur in fuels was seen as a quick way of reducing emissions. i would not run it in newer motors however as they were made to run on current fuel formulations. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease … The pro and con … I was also intrigued by the use of 2T oil in the diesel tank as I had read a lot of … In fact, diesel base fuels that are sold by the refineries have to comply with a strict lubricity specification and in many cases they are … Here … Maybe a stupid question, but what effect does putting 2cycle oil in the fuel tank have on the fuel filter, specially people that use it a lot. Racers can't win what they don’t finish. However, because the motion is reciprocating (stop – start – stop), the worn flat spot will continue to grow. Next Last. 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. Meaning, adding 2-stroke oil to diesel doesn’t improve the lubricity of the diesel. The average 60 litre tank will need around 250ml of 2 stroke oil added for you to start seeing the benefits. I ran into a gentleman today with a 96 7.3 and claims to have a million + miles on his truck , he transports trailers all over usa & canada.He has all stock motor , original injectors and it runs great. So it makes it unusable for storing lubrication oil. Go. 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. Via a High Frequency Reciprocating Rig (HFRR), of course. With ULSD, the thinking is by adding 2 stroke to the diesel, you are giving back the lubrication to the fuel whilst also have a cleaning effect on the engine too. It’s not the only paper about lubricants and additives in diesel, but almost all the others are behind very high and expensive pay walls. But running neat bio-diesel in a diesel engine has its own problems in that its cloud point (the point at which it becomes wax and unusable) is much higher than regular diesel. At all. 4,317 Posts #21 • Nov 29, 2015. yamaha1 said: I use TC-W3 2 stroke oil, have been since day one on both my '14 eco and '15 duramax, combined 60,000 miles between the two trucks...no issues I get 2mpg better … Anyone with something from the 1980s can leave the room. The results follow by indicating negligible differences in cetane number when 2-stroke oil is added to diesel at 200:1”. Prepare you fuel, oil on a bench or other suitable surface and have a clean rag and medium sized funnel handy. In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. Anyone doing this witht he powerstrokes. It’s also designed to burn clean so potentially using this again shouldn’t result in any more smoke....it’s just ‘how much’ to use. You’ve all seen the gunk-busting TV commercials petrol companies run, well, no matter what they may claim, all diesel contains detergent which is designed to keep your engine running clean and help to keep deposits from forming on things like injectors and intake valves. They are using the wrong type of 2stroke oil in their test. The former resulted in an almost zero loss of power or fuel pressure while the test with 2-stroke oil revealed a two per cent drop in power and fuel pressure. 1 of 3 Go to page. Then along came the DPF and EGR treatment to further reduce the emission of fine particles and nitrogen oxides (NOx). Scoob. And that it might even cause increased injector fouling over time (increased by about two per cent). 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. See, in some countries, detergents are added at the fuel delivery stage but in Australia they’re added at the refinery stage. Looking at the boundary lubrication of 2-stroke mixed into diesel, the results showed the addition of 2-stroke oil ever-so-slightly improved the wall-coating effect. The researchers concluded that even with minimal amounts of deposits forming on the injectors being broken off with the cold re-start, deposits remained, meaning they would continue to build-up overtime leading to “substantial injector fouling over the lifetime of a diesel engine”. I have noticed some debate online about adding 2 stroke oil to diesel fuel. Do not fill the fuel tank with fuel that contains biodiesel with blends greater than 7%. So if you stop and put $40 buck in and get 10.195 gallons then you would add 10 ozs of oil. Sasol performed testing on diesel containing two-stroke oil at its Fuels Application Centre in Cape Town (see the technical feature in October 2013) and showed that there is no measurable increase in lubricity when two-stroke oil is added to diesel. And, sure, I’m a skeptic too, but the tests were conducted using industry-standard methodology and equipment. These deposits narrow the nozzle holes of diesel fuel injectors which result in less fuel delivery and engine power loss over time. Others argue that if diesel needed this, the fuel companies would have added it themselves. It seems by adding a small amount of 2 stoke in around a 250:1 ratio, users are reporting a much smoother, quieter engine, less smoke and better fuel economy. But why? There is so much stuff on the Interweb about tipping 2-stroke oil into diesel that it can be hard to work out what’s true and what’s not. In other words, the 2-stroke oil has a much lower ash-content as … Mix ratio for 2 cycle Oil The easiest way to remember the mix ratio for two-cycle oil for your truck is 1 ounce of oil forevery gallon of fuel. Now for the test itself. Initially, I didn’t see much improvement on smoke levels from the exhaust, it still smoked a little on start up, and under heavy acceleration, but it had been reported that you have to run through a couple of tanks of the diesel/2 stroke mix to allow the 2 stroke to have some chance of cleaning the engine. An automobile’s 4-stroke engine operates quite differently. While the CSIRO and others have suggested that while particulate matter can be bigger with bio-diesel it is still captured by a DPF and burned but with less volume of particulate matter when compared to regular diesel. Saw that alot of guys are running 2 stroke oil mixed in the diesel fuel in cummins. Diesel fuel in africa has nothing to do with what we have here. With a vast range of different fuel injection concepts from traditional fuel oils, to gaseous and liquid gasses, MAN ensures that you have your future fuel strategy covered. I am now on my third fill up, and I can now report a drop in smoke levels. Maybe a stupid question, but what effect does putting 2cycle oil in the fuel tank have on the fuel filter, specially people that use it a lot. Go. With a vast range of different fuel injection concepts from traditional fuel oils, to gaseous and liquid gasses, MAN ensures that you have your future fuel strategy covered. Two stroke oil is supposed to lubricate engine bearings while it’s watered down with petrol. Modern diesel fuel sold in the UK is ultra low sulphur diesel (ULSD), and sulphur was traditionally used to help lubricate the injection pump and injectors on a diesel engine. Fuel companies, to meet stringent guidelines around diesel composition, must return the lost lubricity to the diesel once the sulphur level has been reduced, and this is usually done via a lubricity improver. 2 stroke oil in your diesel fuel. All of them report a quieter/smoother engine and less smoke, and some report better mpg. Rather, lubricity is the claim made by proponents of the 2-stroke oil addition philosophy but in the test conducted by SASOL, the diesel dosed with 2-stroke at 200:1 was a lot closer to the 460-micron maximum in terms of wear than was the regular diesel. So as the cetane is reduced the BTU's rise which … So, what’s the answer here? 2-stroke oil in diesel Discussion in '6.9L IH & 7.3L IDI Diesels' started by 03wr250f, Nov 11, 2017. Because it's not diluted, it appears black in this bottle. Required fields are marked *. There are plenty of good products on the market like ‘Flash Lube’ that are designed for adding lubricity to Diesel … Starting with a light load applied to the ball full hydrodynamic lubrication will be realised. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease … 2-stroke oil, like most engine oils, does contain zinc. Continuing with a high sulphur content in diesel would have killed the pollution gear and all of us too. In this study two different brands of 2-stroke oil, referred to here as 2SO A and 2SO B, were analysed and found to contain high levels of zinc: You are certainly not the first to claim that adding 2-stroke oil to the diesel fuel makes the engine run quieter. With new injectors, the high-load test was conducted in the same manner for both the regular ultra-low-sulphur diesel and the ULSD dosed with 2-stroke oil at 200:1. Pretty amazing actually for oil so it certainly should work. Unfortunately, most of the testing on detergents in fuel has been performed on petrol and not diesel. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. Don't see it harming other than possibly reducing motors oil lifespan from contamination. If you must run an additive run a specific Diesel fuel additive like Stanadyne. Note: Do not use raw oils, fats or waste cooking greases, these are not bio-diesel. But the abstracts of all these papers have one thing in common and that is that adding 2-stroke oil into diesel does nothing. Based on industry standards for injector fouling tests, the researchers at SASOL hooked up a brand-new common rail diesel engine (they don’t specify the size or vehicle it was from) with brand-new injectors. 255 Posts #21 • Apr 21, 2009. Measurements were taken every 30 minutes. Well, turns out dimer acids were reacting with the crankcase oils and becoming an insoluble sludge. 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 main reason that old-timers suggest 2-stroke oil tipped into the fuel tank is best is because unlike four-stroke engine oil, the 2-stroke stuff won’t turn diesel to gum when mixed in. We took this question to our Facebook page and plenty of people told us they’d mixed the stuff with diesel to improve the lubricity or said that you need to lubricity additives because the reduction of sulphur reduces the lubricity of diesel. Don't see it harming other than possibly … Meaning the ULSD is, more or less, returned to its natural lubricity level. G4GVB New member. You are certainly not the first to claim that adding 2-stroke oil to the diesel fuel makes the engine run quieter. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. It seems by adding a small amount of 2 stoke in around a 250:1 ratio, users are reporting a much smoother, quieter engine, less smoke and better fuel economy. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. The problem with 2T oils is that they have been developed with a lossy lubrication system in mind. Because, science. Now that we know that adding a 2T oil to diesel fuel is unnecessary, let’s take a look at why is it harmful. But the researchers called the result negligible, suggesting, while it slightly improved the effect it wasn’t by enough to recommend its usage. But our Ford Everest long-termer’s owner’s manual says: “Your vehicle is suitable for bio-diesel blends of up to 7% (B7). Okay, so the polar head groups in the lubrication additive are what clings to the metal surface; they’re attracted to it, and the hydrocarbon chains are what forms the boundary protection (lubrication of, say, piston rings). 1 of 3 Go to page. This could result in premature and permanent blockage of the DPF. There was a fair number of people reluctant to give it a go, and most of them had modern cars and were worried about warranty problems, which is fair enough. 255 Posts #21 • Apr 21, 2009. But things didn’t go to plan. But, over the years the concentration levels of the stuff allowed in oil (both 2-stroke and four-stroke) has been reduced because of concerns about health and the environment. Modern … At the end of the test, the engine was showing a drop in power and fuel flow of six percent. Now that the sulphur has been reduced, the thinking is by adding 2 stroke to the diesel, you are giving back the lubrication properties that the sulphur used to provide. The jury is still out in reguards to advantages in 2 Stoke oil usage in diesel with CRD engines Then try good hi spec motor oil and good fuel prior to wasting time And money on T2 oil As for your OP. There are plenty of good products on the market like ‘Flash Lube’ that are designed for adding lubricity to Diesel … Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits. Two stroke motor oil also helps lubricate your cylinder walls. … Largely the reason for this post, so the warning about high-ash 2-stroke oil (relative to the diesel fuel) is very important.
