Biofuel
muddyjames:
my mate ran his 200tdi on veg/diesel mix for a while and now on the pre heat malarky and had no probs. im looking into converting mine soon due to gordon brown raising the pump prices again!
Dr.Ed:
I'm the mate!
Td5's have (i believe) a high pressure lift pump in the fuel tank that feeds the common rail directly, conversion of these engines is meant to be possible (i know smartveg have done a few) but requires a second lift pump in the 2nd tank and some fooling of the ECU as it tends to throw its toys out of the pram if the fuel pressure is off.
300(& 200) tdi's are simpler - the lift pump is on the engine, injection pump is a bosch and can handle veg oil with no problem. The only problem is that as they are direct injection engines if the oil is not atomised correctly by the injectors (say if its cold) then it wil get past the piston rings and contaminate the sump oil which can lead to polymerisation.
oh and it looks like HM customs won't be after their 28p a litre soon either!

Cheers wolfie.
so does this mean if I were to buy new stuff from say Makro that I wouldnt have to pay tax on it to be fuel? Also if I were to say get some oil from a pub for free and filter it myself I wouldnt need to pay duty on it?
Right. Off to the pub :lol: This seems like an ace plan to solve my poor mpg problem :D
