Biodiesel and SVO in a 90TD

(1/9) > >>

bigfatsi:
I've (hopefully) sold my Disco and after the demise of my little Fiesta, I am now reduced to the Octavia and the 90. Missus will not, repeat, will not, drive the 90 to work so it's gonna be my daily driver until I find a cheap diesel commuter.

Problem is that it drinks fuel at a ridiculous pace, getting about 80-90 miles on £20. That means my daily 60 mile commute gets bloody expensive!

Hence why I'm thinking about trying SVO and Biodiesel. I'm currently researching making 'proper' biodiesel in the garage (any suggestions or experience welcome) but just to get started I'm debating whether to try a bit of SVO (Straight vegetable oil?) in it to see what happens. I used to own a couple of chippies so I know where to get oil from.

Who has tried it? Will it be ok at 50/50 or do I need more diesel? Am I likely to kill it? I'm not wanting to go messing around with heat exchangers do 100% is out of the question but what is 'safe' as bog standard? Lastly, has anyone in the NE made biodiesel? If so where can I get the Methanol and Lye?

Cheers guys!

SVO .... not realy worth it in imho .... assuming you do it legaly. Filtered SVO sells for about 72p a litre and you have to mix it with regular derv. At this time of year they suggest a max of 20% SVO raising to 50% in the summer so the saving is limited. Of course the savings are more substantial if you want to deny the goverment their war funds.

Bio is another kettle of fish. Runs fine in my 200 Tdi with no mixing and prices range from 64p +. Even better if you make your own and the rumours are the tax people wont be chasing you for tax if you do make your own.

You can 'dilute' normal diesel with up to 25% of Tesco's finest veg oil and save a few quid or more, depending on mileage.

Its the long term damage that worries me and stops me doing it. I would like to run on veg oil both for the pocket and for the environment, but no-where have I seen any garauntees that it is entirely safe for your engine, and I want mine to last.

there aren't any guarantees with oils , consider yourself one of the pioneering corp , as for running svo from your local supermarket be warned that bulk buying it over anything they consider to be the normal amounts could find you facing the excise man as you leave (asda if i remember the post correctly from a bio site ) as for paying taxes download the form from gov't site and hold it ready to complete the filling of the amounts with a couple of receipts for your oil as its paid retrospectively and they take us on trust to pay . I have run my 200tdi ,p38 bmw and a pajero 2.5,on it with no problems so far, less smoke and more power ,it burns hotter and reduced emissions, as for chipfat the latest thinking on bio sites says if filtered fine enough then nothing needs to be done further but the old school still do it with methanol to be safe , not tried it either way myself so cannot comment . If you want sites on "how to" just type bio into your browser although i see someone asking about setting it up for alternative fuels in here .
