Veg Oil feasability

Sorry to be slightly off topic, but would veg oil work on a '98 S reg 306 DTurbo? (I'm unsure whether they have different pumps?) Also when does the 2500 litre untaxed limit come into place?

Thanks in advance.
 
You also have to factor in that as a business, they will in real terms be paying less for their fuel than normal pump price because they will be able to reclaim the 17.5% VAT and it would be tax deductable too.

For example, as a business if you spend £20k a year on diesel, roughly £3k of that is VAT and at least £3400 would be due in corporation tax, so the net cost to the company would only be £13600.

There are all sorts of health and safety and environmental issues about handling and processing waste oil which would apply if you were refining the stuff commercially. Also modern Sprinters will more than likely be common rail which won't run on veg oil without killing the injection system in double quick time.

It may be worth seeking out a reputable supplier of biodiesel which is usually a bit cheaper, but a bit of negotiation with a fuel card company may well yield bigger savings.

If its got a Bosch pump and its not freezing outside, then yes.
 
you can run a mix without any complications so i have been told, so what would be the best mix, to ensure the car doesnt get damaged, its an 05 vw golf 1.9tdi, a 50/50 mix is good for summer, and a 33% mix is good for winter, would this worl properly? what sort of injector does the golf use? i own a restaurant so i have access to 50-100 litres of used veg oil every week, which we normally throw away, obviously the oil would have to be cleaned, by the use of a few filters but this shouldnt be a problem

I'm guessing an engine that new will be common rail? You need to run it on converted biodiesel, NOT vegoil mix (unless you enjoy replacing your injectors every few days ;))
 
Yes, do NOT use veggie oil on a common rail diesel unless you enjoy taking your car to the garage.

Once ECU's are involved the engine is really too advanced for such fuel.

No? oooooh, things are looking better in that case :D

Check what pump it is, that will dictate what sort of mixture you can run.
Bosch = lots of veg, little diesel. Lucus/Cav/Delphi/Rotodiesel = little veg, lots of diesel.

... really?

It sure doesn't sound like an old mechanic diesel. In fact it can be remapped so its clearly not going to be using an old Bosch fuel pump like the XUD engines.
 
Nitpicking at its best IMO, its a PD engine (Pumpe-Düse / pumpjet direct injection), and as such has injectors, an ECU, and almost all of the same complications of a common-rail diesel engine.
 
PD is fundamentally different from common rail.

Common rail has a high pressure pump driven off a belt or chain that pumps fuel into the rail, the injectors are piped into the rail and have solenoid valves in them to control the fuelling.

PD injectors are driven by the camshaft and pressurise the fuel in the top of the injector and spray it into the cylinder, which is why they need special oil and sound a bit mechanical.

Given the cost of the components, I wouldn't chance alternative fuels in them.

Same idea just a different implementation - high pressure and more precise injection to promote better combustion.

PD development has stopped - all new VAG diesels will be common rail. VAG were unwilling to fund PD development on their own.
 
Common rail systems don't like veg. simple as.

You need to look at biodiesel (the stuff you get on the forecourt will be 5% biodiesel)

That's because you aren't making it yourself ;)

After your setup costs, you can make your own biodiesel from waste oil for about 40 - 45p/l.

You can make veg oil. You won't be making biodiesel as such.

Unless you can transesterify fatty acids yourself?
