Thread: Fuel additive for TD5

and just for the record I still use Redlines RL2 commercial engine diesel 'conditioner' occasionally as at least it has a fair bit of legitimate, verified testing behind it, but I'm under no illusions that I can feel anything different in any of our diesels.

no requirement to, its a lite milk. just turn the lizard upside down then milk it under the upturned bucket, centrifigual force takes care of the rest.

Based on the "more is better" theory that modern man survives on, if I run my car on straight 2 stroke, add all of the cleaners, performance enhancers, system cleaners etc I can find, along with my hyclone & my Power Chip, I should be able to capture the diesel from my exhaust that it would produce, and it would be as pure as a new born lamb...









BTW - just for the record.... I tried the 2 stroke in my car for about 12 months, keeping records of fuel consumption. I PERSONALLY did not notice any difference at all. But, that is just MY experience, using a range of fuels.

Abstract: The lubricity of diesel fuel has a direct effect on the service life of the fuel injection equipment, and when alternative fuels are specified, is of vital importance. One such fuel is the Swedish diesel fuel, MK1 which contains low levels of sulphur and low lubricity. This paper investigated the use of ultra low sulphur diesel (ULSD) and fatty acid methyl esters derived from rapeseed (RME) blends to improve MK1 lubricity. Fuel lubricity was assessed using a high frequency reciprocating rig. The wear scar diameter of the ball specimen was measured using optical microscopy while the wear profile and surface roughness of the disc were analysed using a profilometer. Scanning electron microscopy with an energy dispersive spectrometer was used to evaluate the microscopic topography and chemical compositions of the surfaces. Results confirm that MK1 has poor lubricity when compared to other base fuels. Of the blended fuels. ULSD showed little improvement. However, a small percentage of RME improved the lubricity of both the pure MK1 and the blends. Analysis of the worn surfaces indicated that chemical compositions of MK1 did not adsorb and react as well when compared with those of ULSD. RME and selected blended fuels. (C) 2011 Elsevier B.V.

Abstract: Use of biodiesel in automobile can significantly reduce our dependence of fossil fuel and help reduce environmental pollution. However, there are concerns over the compatibility of currently used automotive materials in biodiesel. A few automobile manufacturers extended their warranty only to lower blends of biodiesel (e. g. B5). Higher blends (e. g. B50 or B100) are still not covered by warranty. In automobile fuel system, metallic materials like ferrous alloy and non-ferrous alloys, and elastomers come in contact with fuel. Biodiesel, having different chemical characteristics from diesel, can interact with materials in a different way. It can cause corrosive and tribological attack on metallic components and degrade elastomer parts. This paper attempts to present an overview of the work done so far on the compatibility of biodiesel with automotive materials. (C) 2010 Elsevier Ltd. All rights reserved.

However on the wear/lubricity front. On average, Bio is better than petro-diesel (from the paper above):

Abstract: The diesel fuel was mixed with the rice husk bio-oil using some emulsifiers based on the theory of Hydrophile-Lipophile Balance (HL. The lubricity of the bio-oil/diesel fuel blend was studied on a High Frequency Reciprocating Test Rig (HFRR) according to ASTM D 6079-2004. The microscopic topography and chemical composition on the worn surface were analyzed respectively using scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The profile and surface roughness of the rubbed trace were measured using a profilometer. The chemical group and composition were studied by a Fourier transform infrared spectrometry (FTIR). The results showed that the lubrication ability of the present fuel blend was better than that of the Chinese conventional diesel fuel (number zero). However, the anti-corrosion and anti-wear properties of the fuel blend were not satisfactory in comparison with those of conventional diesel fuel. (C) 2009 Elsevier Ltd. All rights reserved.

I know TD5s are not commonrail, however:

Abstract:

The paper presents analysis of performance and emission characteristics of a common rail diesel engine operating with RME, with and without EGR. In both cases, the RME fuel was pre-heated in a heat exchanger to control its temperature before being pumped to the common rail. The studied parameters include the in-cylinder pressure history, rate of heat release, mass fraction burned, and exhaust emissions. The results show that when the fuel temperature increases and the engine is operated without EGR, the brake specific fuel consumption (bsfc) decreases, engine efficiency increases and NOx emission slightly decreases. However, when EGR is used while fuel temperature is increased, the bsfc and engine efficiency is independent of fuel temperature while NOx slightly increases.

Abstract: The ultimate goal of automotive manufacturers is the development of more powerful, economical and environmentally friend internal combustion engines. Also of note is the importance of noise reduction by increasing the fuel injection pressure to unsatisfactory levels. Obviously, higher injection pressures require materials of higher strength and lower production tolerances. However, one of the main issues regarding the use of these high-pressure fuel systems is their dependency on fuel quality. Therefore, concurrent efforts to improve diesel fuel quality are supremely important. In this study, we discuss the earliest engine problems commonly encountered in new generation diesel engines and their economical consequences for vehicle owners and the Turkish automotive market. We found that most of the problems in connection with the Common Rail (CR) systems emerged from inadequate fuel quality. In Turkey did not proceed at the same rate as the increase in diesel vehicle sales, because the improvement of fuel quality. Other reasons for the problems include faulty operation, lack of necessary knowledge particular to CR technology and late response to a problem by the drivers.

2SO is not for lowering your consumption. I use 2SO to enhance the lubricity of the diesel and to prevent coking of injectors, EGR, etc, and because the diesel in SA and surrounding countries is sometimes diluted with parrafin and may be dirty.

If you start using 2SO on an old TD, you MAY see a slight improvement in consumption once the 2SO has cleaned the internals.

I used 2SO in my previous D2 Td5 AT - quicker startup in winter, smoother idle, smoother gearchanges.

Currently I use 2SO in my Audi 2.0 TDi (PD) - quicker startup in winter, smoother idle, less smoke; and in my Puma - smoother idle, less clattering.

Hi All,

I seem to have a mental block. I can't seem to get my head around the formula for the 200:1.

Can someone please either give me a push towards working it out, or, how much do I put in. My tank is 95lt.

Cheers.

.47 of a litre. Remember, when you fill up next time you are unlikely to put in 95 litres. just divide the amount of fuel you put in by 200.

No-way!

Too easy.

Thank you.
