Ive been using a 70/30 mix in my 2.8 pajero and it runs great, in the colder months i change to 40/60 in favour of diesel as it can be lumpy to start with.

Ive used a 50/50 mix in my old transit and it runs ok,dont use veg oil in these unless you have a bosch fuel pump,the lucas ones are damaged by it.

Unless you declare the use of veg oil as a fuel you can be given the same penalty as for using red diesel.

Makro do 20l for a tenner

my buddy has been running a hiace for 2 years on 100% veggie oil,pours it straight in.only switches back in the winter because of the cold starts but if you mix it that shouldn't be an issue,he doesn't bother to mix.

You can NOT put veggie in any car and just drive away. If you have a direct injection (eg TDI), common rail (eg CDI), JTD or whatever, forget it. If you have a modern all singing electronics-everywhere car forget it too. You could use biodiesel or install a twin tank, but do NOT just add veggie to your tank.

 

Same goes for anything with a CAV/Lucas injection pump - even in blends of oil/diesel it could literally seize as you turn the car over and drive away. Seconds is enough sometimes.

 

IF however, you're sensible enough to have a pre-1998, INDIRECT INJECTION diesel (turbo or not, doesn't matter), with a Bosch or Nippon injection pump - or better yet a Mercedes inline pump) then you're laughing :toast: Suitable cars include Citroen XZ, Xantia etc with the XUD9 1.9 (T)D engine; to 1998 Mercedes with the inline pump on the 2.5, 3 litre etc engines (190D, 200D, 300D, Sprinter etc); Peugeot 205, 306, 405/6 with the XUD9 engine (ONLY if it has a Bosch pump, some are Lucas - CHECK!); Rover diesels with the Peugeot engine; Vauxhall Cavaliers with Isuzu engines; Vauxhall Astras with Isuzu engines; the list goes on.

 

You will NOT be "done" for driving around on veggie, as you would be for red diesel, IF the following criteria are met:

 

From 30th June 2007, the duty was lifted for small "producers" (users) of biofuels. This includes bioethanol, biodiesel, straight vegetable oil and other biofuels/fuel substitutes. The criteria is simply that you use less than 2,500 litres a year PER PREMISES. So if you and the Mrs have a suitable car each, you can use 2,500 litres between you.

 

If you are to use less than 2,500 litres of veggie (over 208 litres a MONTH, or 52 gallons = about 25,000 to 30,000 miles a year!) then you do NOT have to register with Customs, you do NOT have to pay ANY fuel duty on the veggie. Just pour it in, and drive :D

 

The only requirement is that you keep records, which must be retained for six years, detailing your usage. They only need to be a pocket book in the glove box saying "DATE" and "LITRES ADDED TO TANK". So a list like...

 

1/7/07 - 10 litres

10/7/07 - 20 litres

23/7/07 - 10 litres

 

is absolutely fine. It's just to show, if stopped, that you're not using more than 2,500 litres on a rolling 12 month basis. If you DO go over the 2,500 litres you have to then declare your usage to HMRC and start paying fuel duty :rtfm: Dunno many lads who'd be going over though! :whistling::feck:

 

Ideally you'll budge the injection pump timing 2 degrees, fit SLIGHTLY longer glow plugs (Bosch Duratherm recommended for veggie) and make sure the engine is in good nick on regular diesel first. No point trying to veggie a knackered engine, the higher viscosity can (will) push it over the edge. For normal engines, as above, you'll run just as well on veg as on derv - though maybe a puff of white smoke on starting and a bit "grumpy" til warm. But at 50p per litre (or free if you collect waste used oil from chippies!) - who cares?! :big_boss:

DONT put waste oil from chippies as recommended here without treating it ,not just filtering. It WILL cause you PROBLEMS

sorry about the caps, just following fashion it seems

 

 

Quite right. I didn't mention ANY processing methods on purpose... my post was already too big for the envelope. Anybody wanting to use waste vegetable oil (WVO) from a chippy etc should do a fair bit of research first. You'd need to filter it into a tub/vat/IBC (depending on your quantities) and allow it to stand for a couple of weeks to settle out most of the water, tallows and the FFAs (free fatty acids). Then you're best investing in a decent pump from Machine Mart, and a set of filters (say, 20 micron, 10 micron, 5 micron and 1 micron) and pump through the top layer of settled oil. You should be left with decent gear after that. BUT like I said that's a summary, not a recipe - read up if you're using waste oil people!!

 

Personally I just buy it new - at ~50ppl it's worth the price to save on hassle (for me, anyway) and it's still cheaper than even red diesel (at the garage anyway). Anyone with a CDI, DI etc engine will have to learn how to transesterify the oil into biodiesel. See www.vegetableoildiesel.co.uk and get to the forum ;)

 

Cheers.
