Black Diesel??
Hi all,
I know that we cannot run the CDT/CDTi on BioDiesel, but in general searching of the internet have found Black Diesel (made from waste oil). Are we able to use Black Diesel, or is it the same as BioDiesel? Thanks in advance.

The only diesel you should run your CDT/CDTi on is the one that you buy from the usual fuel suppliers, and ideally not the supermarkets, the diesel BMW engine is a sophisticated state of the art common rail engine, not a farm machine, you been warned.!!!!!.

Biodiesel is now a generic name given to any fuel meeting the EN spec that isn't made from new fossil fuel.
It can be either made from recycled or new vegetable oil, or basically any recycled oil. My brother runs his Xantia HDi on very black looking biodiesel and has done for over a year, it's made to EN spec and is £1.05pl. I reckon these engine would probably run fine on it, but I'm not willing to be a guinea pig

So still not sure... He mentions about using it mixed with normal pump diesel. More research needed me thinks.

Is it actually black? If so then it must contain soot still, that is going to ruin a common rail engine very quickly.

From a program seen on TV HM Customs and Excise aren't very happy with black diesel as been known to be red diesel mixed with old engine oil to disguise colour, if they find it they will likely impound vehicle while it's checked.

Your original question was whether they differed, I'm just answering that I'd treat it all the same unless it meets EN specification

See the following extract and note the final statement
Process Filtering The process of preparing the waste oils for use in diesel engines starts with the filtering of the waste oils through a 20 micrometre filter. This is done with the raw waste oil in order to remove the largest particulates from the oil. Mixing The raw waste oil is mixed with new diesel fuel to a ratio of 50/50, heated up to 160 °F (71 °C).Or mixed with petrol but not heated. This helps the old and new oil to blend and to flow better for the next step. Filters The heated or mixed oil is then passed through progressively smaller size filters for added purity and safety of the final product. The filters start at 15 micrometres and can be as fine as 1 micrometres. Product The final product is a petrochemical fuel that will burn in most non common rail diesel engines with no modification.Or at most, the addition of a lift pump. However, this fuel may be "heavier" (that is, more viscous) than normal diesel fuel and may not flow properly in colder climates.As of 24-03-2012 Blackdiesel costs around 30c per liter to produce

Are you meaning that Tesco Diesel is supplied by Esso? Some, or all of the Tescos? Does it have a sign saying it's from Esso? Tesco's diesel produces a bit of black smoke on overtaking hard on mine. Asda's the same, Morrison's is worse. Someone said that some Sainsbury's were supplied by BP and had a sign saying so - but I haven't seen that yet. As a comparison Shell V-Power seems to give more power - and definitely no smoke at all. Singvogel. |
