nope, but I wish :) you can use it for house heating. Not necessarily some boilers are not compatible so anyone thinking of doing so check with manufacturers. in general the quality of cars is decreasing, and I doubt that now are used more robust components. I believe in opposite and the reality confirms it. Old cars have no problems even with used oil from mcdonalds... Again not in all cases, I was speaking in terms of the seals that are of a different composition these days to take more high octane fuels so won't perish like rubber. so you think that manufacturers are worried to reccomend biodiesel because of oil companies? :) And they are not worried to constantly work on decreasing the consuption with more efficient engines, aerodynamics, downsizing, start-stop systems, hybrids, energy tires...? Only because they feel it is politically correct with the eyes of the world on them as the biggest polluter, and because they know that with fuel prices as they are they need a new edge, that's how it is. I think that car manufacturers do not test their wehicles on biodiesel, furthemore the quality of biodiesel may by varying and the sensitivity on fuel quality of new turbodiesel engines is fact, it is the reality, not just words from somebody. I am not surprised that car manufacturers do not reccomend it. Nail on the head, it is because there are people who make there own and isn't controlled and they are worried about the warranty claims. I am surprised that you have bought car for 40 grand more like 15 grand and now you want to save every penny with high risk. Even with high quality diesel has IS220d quite lof of problems with reliability, with price tags of new parts: EGR app 350 eur, turbo 2500 eur, DNPR 2000 eur, injector I guess about 400 eur. The proof is that if it runs on diesel it will run on biodiesel, we just need to make sure it is good biodiesel, and in trms of economics I can fill my Lexus up for £20 rather than 60 plus and that's not going to have any effect on EGR's or DNPR's or turbos etc. If you want to drive economically, buy old jetta 1.9d or something similar and you will have no troubles with veg oil... No thanks

Dear me Matus, anti green or what, you must own a fuel station or something, agreed about the planting of food but what about the recycling of waste veg oil that would otherwise be wasted into the land fills? Biodiesel has detergent properties so should actually clean your system and not clog the injectors. Bio does indeed rot rubber seals but this generally is on older vehicles, more up to date vehicles should be equipped to deal with this problem using more robust components. The only down side I know is that it cleans your system so much that your fuel filter will clog and once you have changed it, it will never need changing again. I too got in touch with Lexus on this subject and they confirm that due to BS EN bla bla bla, they only recomend using top grade diesel and when I asked is there any reason why I shouldn't use it they kept re-iterating this point so didn't get a straight answer, surprise. Speaking to other users of biodeisel who have asked their respective dealers also get the same reaction, they seeem worried that the oil companies will tern against them, or they are being paid not to promote it. In all other cases where folk have ignored the recommendations there has been no adverse problems in vehicles that I know about, hopefully someone will know better and can advise. One more thought, Morrisons is supplying biodiesl as an alternative at quite a number of their stations around the country now.
