one-lady-owner 1 Posted February 9, 2010 (edited) biodiesel is designed to be used in standard diesel engines, best bet, run your tank nearly empty, stick a tenners worth in and see what happens, it won't corrode any seals or anything daft so I wouldn't worry about that, if you only stick a tenners worth in and the engine doesn't like it you can fill the tank with normal diesel and it'll dilute it back out, easy! Let me know how it goes as I'd love to try it myself for that money!! Just out of interest where have you found the bio?

jackherer 543 Posted February 9, 2010 I used plain veg oil in a Xantia TD for ages so you should be fine with biodiesel. Share this post Link to post Share on other sites
All Praise The GTI 3 Posted February 9, 2010 sorry to butt in but has is there anything cheaper then white diesel i can put in my 306 hdi without killing it? Share this post Link to post Share on other sites
welshpug 1,737 Posted February 9, 2010 red The pump biodiesel should be fine, some standard pump diesels actually contain some bio in them already, what they dont like particularly is straight veg oil. The bosch mechanical pump on the Xantia is fine though. Share this post Link to post Share on other sites
All Praise The GTI 3 Posted February 9, 2010 apart from the risk of getting my car crushed would just a little cherryade mixed with the white do any harm to the fuel pump etc? not that id ever put that in my road car ... Share this post Link to post Share on other sites
welshpug 1,737 Posted February 9, 2010 (edited) not at all no, know of several vehicles that have been run on it without any ill effects vehicle was never used on the road hofficer, honest! Edited February 9, 2010 by welshpug Share this post Link to post Share on other sites

pug_ham 245 3 Cars Posted February 10, 2010 sorry to butt in but has is there anything cheaper then white diesel i can put in my 306 hdi without killing it? AFAIK most of the hdi's are ok for use with biodiesel. Maybe give Pug a call & ask them but I do remember reading somewhere its can be mixed in but not run 100% iirc. Graham.

peakrevs 0 Posted February 10, 2010 AFAIK most of the hdi's are ok for use with biodiesel. Maybe give Pug a call & ask them but I do remember reading somewhere its can be mixed in but not run 100% iirc. Graham. A farmer local to me has sadly given up dairy farming and gone over to production of biodiesel. This is proper diesel made with vegetable oil, methanol and sodium hydroxide which are a catalyst. I've been running my Hilux on 100% biodiesel for a couple of years and it is all gain. It goes better, more mpg and lower emissions. However, we have tried more modern engines on it, (100%) and they don't run as well because I believe they have an ECU which is not programmed for bio-diesel. The other more worrying aspect is that if not all of the methanol has been removed in the production process, it could attack any elastomer seals in the fuel system. We certainly had a catastrophic seal failure on the fuel pump on our 405 turbo diesel which had been running on 100% biodiesel. Now I don't know if the failure was due to methanol but I think it possible and diesel pumps are very very expensive to repair or replace. So in conclusion I believe, if you have an older vehicle there will be no problems with performance when running 100% biodiesel but the slight niggle about the methanol remains.

one-lady-owner 1 Posted February 10, 2010 Some of the XU diesel engines running a lucas pump are known to have fairly catastrophic pump seal failures but the bosch pump seals are ok on it Share this post Link to post Share on other sites

omega 82 Posted February 10, 2010 it is well known that lucus pumps dont like veg oil or bio i have also heard that some bosch pumps have failed as well.it appears that there are two sorts of seals in the pumps and a small amount of bosch pumps have failed the reason the seals fail seams to be that the bio attacks them/they do not get the lubrication from the bio to keep them flexable so i think a mix of bio and pump diesel would be best but what ratio?

DamirGTI 367 Posted February 10, 2010 There's this Biodiesel fuel variants as already premixed with diesel B100 is straight pure Biodiesel (but now fully esterified as there was some issues with using it in direct injection engines in the past due to higher viscosity and extreme nozzle choking..) B5 , B20 , B30 ect. are all mixtures of Biodiesel with regular diesel fuel (but B5 is said to be the only Biodiesel mix covered under OE warranty in the case of engine damage when used in new cars ..)
