Bio Fuel

[Tinman]

Just filled up at the local survo, found no frothing at the tank found a bright yellow stuff coming out of the pump. Have a TDV6 Disco 3 blood started to rush,no visable signs on the pump. Made a bee line to the office, took a bit of prodding to get out of the attendant that it was bio. 76 litres full what to do. Have found it very ruff starting when cold, not quite as nippy as before. Will run out the tank then fill with the good stuff.
Did some research and found that there is active solvents in bio which dissolves the sludge in your tank and lines, so if you have been using diesel for a number of years then expect to be changing your filters for a while untill all the sludge has disappeared.Also the solvents attack rubber fuel lines and fuel pump components that are rubber. New model vehicles use a different elastomer for their lines etc so they are not as vunerable.

Generally, it's not going to be a problem, one tank of bio in your TDV6. It seems that ( at least in Sydney) Metro Petroleum outlets at various places are switching to bio without any notices to purchasers. You will note that they may be a little 'complies with..." or a "supply not necessarily same brand" sticker on the pump. You newer Disco owners should stick to the major outlets if you are concerned with getting a load of bio. Also, letting others know the location of the bio is a good idea - for both users and avoiders of bio. Lastly, for others who read this - there was a note on one of the sites regarding bio and Landrovers that the rubber components resistant to bio entered service about 1994.

personally i would be inclinded to run it to half a tank then put some normal desil in to dilute..........rather than allowing to run it all the way down.....

we were only warned the other day about bio diesil in, friend said the only engine that will put up with the bio diesil is the 200 tdi

it has nasty effects on all other engines that landrover do if used frequently, and expensive effects such as injectors..........

aparently the bio diesil is renouned for making seals swell

G'day Dullbird,

Just out of interest, who was the person suggesting that the 200tdi is the only engine that will cope with biodiesel? Keen to hear if you've got some credible sources with some interesting findings.

I'm sure you've seen this link then...............

I haven't followed up on how his td5 is going, but in europe, most direct injection common rail turbo diesels are coping fine with B100 (100% biodiesel). Several companies are now warrantying their new diesels forbio too.

I'm no expert but i have also heard that dinodiesel/petrodiesel without sulphur actually shrinks rubbers so perhaps biodiesel is not actually swelling the seals, just returning them to original shape. Food for thought.

Keep the info coming!!

The Landrover Monthly (LRM) for June 2006 has an article on bio diesel. The issue for the TD5 is the injectors get clogged. Land Rover has approved the B5 blend for the other diesel engines at least in Europe (This is for warranty issues).
