I think you and alot of people to be honest!
Quote:if you have an indirect injection diesel engine with a bosch pump then you can more or less just run 100% veg oil. just a mix of diesel and small amount of petrol and perhaps a heat exchanger in the fuel line to thin out the fuel.
for one, DO NOT mix diesel and petrol!!! views on heat exchangers are mixed from what I've been reading up on. But it is best to heat the oil before it goes into the engine, as it is thicker then normal diesel. Some folks find it easier to start on 'dino diesel', then when the engine is up to temperature, switch over to veg/bio diesel.
Quote:the reason being a bosch pump is that they dont require lubricating from the fuel, they have sealed bearings or something like that. the lucas pumps apparently rely on the fuel to lubricate, and veg oil would just gum everything up.
yeah, your pretty much there - both pumps' bearings are lubricated by the fuel, however on the Lucas pumps the actual pipe is thinner then on the Bosch one, so in a short space of time they pack up because the veg oil is thicker then diesel
Quote:this is what i gather. ill be going on to this since in the last month my out goings from fuel were approaching £300 when using unleaded!
ouch!!! I must admit, if I wasnt so attached to my old Cav (which I'm gonna convert to LPG for about £450), then I'd be buying an old Merc or an old Vauxhall diesel straight away!!
Quote:should hopefully help my delorean/student loan fund!
and what better reason do you need to switch to an eco friendly fuel that is half the price of petrol or diesel on the forecourts!
Check out the biofuel forum I mentioned in the first post, to check exactly what cars are compatible for running on veg oil - I know alot of Vauxhalls are ok, more specifically those fitted with the Isuzu Diesel engines - ie the 1.5D in the Mk1 Corsa and the 1.7TD fitted to the Mk3 Cavalier (except the Envoy base model) and higher spec Mk3 Astras (Sport, GLS and CDX). I know that the W210 (?) Merc E-Classes - ie the 250D and the 300D will also run on veg quite happily too.
Funnily enough, I was watching 5th Gear just now, but I was very annoyed at their 'performance test' comparing a Merc 250D running on Veg and a Jag running on methane (by product of making cider apparantly) - well of course a 4yr old Jag will be faster then a 15 year old Merc!! Jeez......... from what I've been reading, you will suffer no loss in performance or economy, and your engine will actually run quieter and last longer, because there are no horrible deposits like you get with normal diesel. Also, the methane conversion cost £2500, he had to have a huge compressed gas tank in the boot (like a giant LPG tank), and methane costs 70p per litre.
Also, dont be taken in by the "biodiesel" being sold by Tesco. Their biodiesel is made by a company called Greenergy - who Tesco own 20% of. They make their biodiesel from palm oil which is grown in the far east and also South America - due to this, vast areas of rainforest are being destroyed and burnt (!) to make way for these palm oil plantations. It is estimated, that due to this deforestation, the Orangutan will be extinct within 10 years.
Seriously tho mate, if you do want to explore the veggie option further, go on that forum and do some research, and I think you'll be pleasantly surprised!
Cheers,
