veg oil as diesel fuel? Answered

With th' price of diesel fixin' to skyrocket in th' forseeable future ,  what would need to be done in order to use cookin' oil (brand new ,  straight from th' supermarket) in my cars tank ?

I don't think it makes a difference ,  but I need to be sure I wont damage th' injectors or fuej pump or anything else by dumpin' a few bottles of rape seed oil in and runnin' it !!


"Straight veg oil" - SVO needs a separate, heated tank, and some way of switching from dino-diesel to it, once its warm. You need to bring the engine UP to temperature before you run SVO, and, when you are about to stop, you need to go BACK to dino to "cool off".

Heating needs to be supplied to the fuel lines too. I have a link to the bits somewhere.....

Don't do it with a Lucas injector pump.

You can run up to 50% SVO in dino in the summer, but (given where you are) only about 20% in the winter.

Thanks , I knew it werent gonna be as easy as jest pourin' cookin' oil into my tank and you have explained why ! Now I can do what Kelseymh suggests and find out what else needs doin'

When we had our first diesel (an 81 rabbit) it said in the book, if need be we could got to the groc. store and buy a gal, of peanut oil.

Is this still true? they were specific on peanut oil. We know of someone in the UK that regularly goes to store and buys oil for his car.

Is new veg. oil going to be cheaper than diesel? I don't buy either so I'm just asking.

This gov is more rapacious and greedy than I thought possible ! You caint use even supermarket oil without payin' FUEL TAX on it and that effectively eliminates any savings you might otherwise see ! Are all politicians this screwed in th' head ! Robin Williams comment "Politicians are like diapers ! They should be changed often and for th' same reasons !" has never ben more relavant !

From what I see , any money that should have been spent on road repairs went into some useless civil servants (now THATS an oxymoron fer sure) pocket ! Are you aware that 90 percent of what you pay fer automobile fuel in this country is pure tax ? And fer th' record , it was my understandin' that th' £150 road tax I have to cough up annually is supposedly for th' road maintenance you speak of ! As far as I see you folks pay way too much tax fer WAY to little return

Ah, you're probably right. Why don't you run for office and try to fix things?

I'm too old and cynical and , 'cause I caint be bought ' cause I jest don't care ! therefore there aint no way I would get elected in th' first dam place

with diesel runnin' at £1.20 per liter at th' pump and rape seed oil at £1.00 per liter , Its already cheaper to buy at th' groc store !!

A search for "biodiesel modifications" on Google gives numerous useful results. I guess you didn't bother to do that before posting?

I aint all that compuliterate and , to get good results from a google search you need to be able to ask th' question properly ! The reason steve gets best answer is 'cause he answered exactly what I asked ! I thank you very much for th' additional info !!!
