can you run a pd diesel golf on bio diesel (proprely brewed stuff) i am running my seat inca on 100% bio just now and i want to use some in the wifes golf but not sure how it will run, just wondering if anyone else on here is using it

Moving to Diesel discussion.

I wouldn't mind knowing the answer to this as well....

 We had this discussion before and I think it was said that only the older breed of diesel would be happy to run on Bio - the PD wouldn't like it at all

 Elsbett do a conversion kit for PD engined VW's, check their site:

The main problems with Bio diesel and modern diesel engines is that they are very good at thermal efficiency (don't get very hot) so a kit is needed to warm the BioDiesel and not run the engine in it until the engine is warm too. There are further complications with the Bio Diesel emulsifying the engine oil.

A few years ago I ran a 306 D Turbo (Bosch pump) for 10 months (18,000 miles) on straight cooking oil from Tescos, no mixing, no additives, it would missfire for a couple of seconds on the first cold start but was then great for the rest of the day.

I also know of someone with Non PD golf that runs in on 60% Cooking oil 40% pump diesel with no issues, apart from smelling like a chip van

 my seat inca has the vw 1y non turbo engine and it runs great on it a little misfire on start up in the morning but thats it. the reason i am asking is that i can get it for less than half the price of diesel so i am saving a load when using the van, but if i could get way with using some in the wifes golf that would be great cos she is doing nearly 500 miles a week in it and the fuel bill is getting silly and is not going to get any better. she actually said if her car wont run with any of the bio in it i have to get her a car that will (a mk3 tdi or a early mk4 tdi) i was thinking.

Ive heard of, but cant 100% confirm, of a 150pd with a hybrid running close to 220bhp on chip fat!! Might be mixed not sure

 look in your owners handbook, i am sutre there is something about it, it has to be to a standard of some kind, iso number . I trhink vw said it was iok in most cars >2004

Go to this link, second paragragh mentions vws

All diesel sold in the UK already has 5% Biodiesel mixed in with it. In theory, you should be able to run your Golf 150 on pure Biodiesel, but the source of your fuel is of utmost importance. This is tha main reason that manufacturers are holding back from full certification for all their diesel engines, because they can't guarantee the source of the fuel to be pure enough. If they stated that all diesels could run on 100% Biodiesel, numpties would immediately assume that sticking 50ltrs of Tesco finest cooking oil in the tank was okay. Biodiesel is one thing, cooking oil with conversion kits, mixed with white spirit, waste oil from the local chippie etc. is a completely different issue and not to be confused with Biodiesel.

So if your source of Biodiesel is from a refinery where the supply is certified to EN14214 you should be fine with it. If it's home brewed, or from a bloke you met down the pub, then probably not.

Also, more frequent oil changes are a good idea initially to make sure that you're not contaminating the sump oil with vegetable matter. There's some pics doing the rounds on the net of someone who used freely available Biodiesel or veg oil from some unknown source and the sump is full of solid black sludge.

 Yea that right ^^^^ if your thinking of using biodiesel make sure it conforms to EN14214 specification, anything else is far too viscous and will clog filters and isnt very good for your fuel pump or injectors and will give you crap mpg's, crap power, and crap emissions!!. Most Golf's can run on biodiesel even the PD's, it even says so in your manual that it can run on pure RME (Rape-seed Methyl Esters) which is the real name for biodiesel.

I have run B50 (50% bio) in my 115pd before and there is no performance difference, just a slight increase in fuel consumption as the engine needs to burn more of it as it struggles to atomise and burn as well due to its greater viscosity.

stick to V Power diesel in my opinion, great on MPG's, i got 756 miles to my tank last week!

 are you sure that all diesel has 5% bio in, at my fuel station there are two diesels one bio diesel (5%) and one normal?

Renewable Transport Fuels Obligation (RTFO) came into force on 15th of April, requiring all fuel manufacturers to supply at least 5% Biofuels by the year 2010. Suitably vague wording by our Government once again. What this means in reality is that they only have to supply 5% of their turnout as Biofuels. What was intended (I presume) was that all fuel would take 5% Biofuel across the board, but what may happen is that firms will sell ordinary diesel, and also sell a higher ratio fuel with say10% Biofuel in it. They have until 2010 to manage to provide this but are being penalised (I believe) in the meantime if they fail to provide.

 The PD engine is absolutely fine on biodiesel. If I am right in thinking that not all diesel is blended with biodiesel because common rail engines will not tolerate it due to the injector pressure. A friend of mine has a commercial plant and we have run many vehicles on the fuel, all with the same effect, the biodiesel will dissolve all of the crap in your tank nd fuel lines and dump it in your fuel filter. Hence why it is recommended to replace your fuel filter more often. The car will smoke for a while as all the carbon is stripped from the injectors and the cylinders and eventually when you take it for an MOT, the emissions will be rediculously low.

I wouldnt want to put cooking oil straight in the tank, because given time it will gum up your injectors and cause lack of power and crap fuel economy.

Not currently running biodiesel at the moment because i only use virgin rapeseed oil and with rape prices as they are at the moment, once processed, the fuel is not much cheaper than mineral diesel if you are buying it retail and paying tax.

Not read all the facts on the stuff but there seems a worrying increase of golfs/passats etc coming in with fecked diesel pumps.........one had a blown turbo at 40k....One of the guys has only been used biodiesel from the local stabdard approved one so think the jury is still out on this one.....

VW state that PD engines shouldn't run on bio diesel I rang the technical department on friday to find out, they say its due to the high pressure required by the injectors.

 If the garage says different then I stand corrected, was just going by the fact that the handbook says "Vehicles with diesel engines can also run on RME fuel (Rapeseed Methyl Ester)". Also on the inside of the fuel cap of the mk V there is a sign saying no biodiesel whereas on the mk IV there isn't
