Interesting reading the varied views on the subject.

Rudolph Diesel invented the Diesel engine to run in Africa on VEGETABLE OIL (Peanut) not a Hydrocarbon derivative, and the diesel engine will run on vegetable oil quite happily providing the vegetable oil's viscosity is lowered, usually by mixing with Diesel or passing it through a heated fuel filter prior to pump injection.

From what I remember from my experience in Hydraulics, vegetable oils can be used in a system WITHOUT detrimental effect on the seals in that system be they Natural Rubber or Synthetic,
on the other hand Synthetic oil (hydrocarbon base) can ONLY be used in a system with synthetic rubber seals,

Here's an Interesting site that will answer all of your worries and concerns

Hi
Rudolph Diesel's first engine was designed for and ran on powdered coal,not much lubrication there.

A mate of mine runs his 1992 VW T4 Multivan 2.4 on 40/60 veggy oil with no ill effects. Laughing

A friend of mine is mixing vegetable oil with diesel,approx 40/60 and running his vw passat with it.He has been doing so now for about 5 months and reports no ill affects on his car.Has anyone on this forum tried it?If so how does your vehicle run? Dave.

Ah! that explains it.

My neighbour has laid his Land Rover up and is currently usind an old Peugot diesel.

Every time he goes past there is a very pleasant, mouthwatering smell of fish and chips. Shocked

I have made and have used biodiesel in my 03 Focus TDCi. Started mixing with Mineral (pump) diesel and then ran 100% without problems. Just due to time constraints (always in my Hymer) I struggle to make the stuff all the time. I'm in fact thinking of selling my home-made bio-plant with shed if anyone is interested?

I currently run my Hymer 660S (Mercedes) 100% on veggie oil. Have now done a 1000 miles. No problems but takes longer to start on a cold day. During Winter I'll buy a proper conversion kit so the veggie oil viscosity is less of a problem. My used supplier dried up, so I buy from a wholesaler. It's 86p a litre and rising. However, just found out my neighbour works as a local restaurant manager so I may be in luck with the free stuff.

Power is a wee bit down, but then it aint a modern horse and pulling 3.5t I aint worried.

Funny thing is, when I do the sums running my car on Pump Fuel at 130p/litre it is still half the cost of running the motorhome on veggie fuel just due to fuel consumption alone!! Smile

how many times are we going to do this to death.

Veg oil is NOT Bio Diesel

Most modern diesels will run on Bio (in fact tescos etc generally sell whats called B5 5% Bio and you don't even know the BS EN std allows them to use up to 5% Bio)

I run two VW T5 174 Tdi and a Merc Sprinter 2.7 on B100 , thats 100% biodiesel but again

Veg oil is NOT Bio diesel and running it in any recent Tdi engine is a recipe for long term problems.

here is the original Technical reasoning.

so thats it then.
Thanks for clearing the subject out alunj

There's someone on the Ford Transit forum who attempted to run his van on vegetable oil. Weeks later he is still attempting to get to grips with the problems caused. He's dropped the tank several times, cleared all injectors and done just about everything possible to even start the thing. Don't try it. It looks as though he will need a new fuel system.

I ran my Pug 406 for 4 years on 70% veg oil in summer and 30% veg oil in winter with no problems and a lovely smell. It is still running as a workhorse with the guy who services my Motorhome.
I would not recommend this to anyone with a vehicle newer than my old 'P' reg pug.
I do put the odd 3 litre bottle of Asda veggie in my Merc engined Motorhome if I need to stretch the range (there are areas with a grocers but no fuel) but it is neither Turbo nor computer controlled so will run on liquified coal if I can find it.
This is my small protest at the price of Diesel but even that protest is being undermined as Asda increase the price of their veggie oil. All my motors get an oil change at recommended mileage or annually (whichever comes first) so I have avoided the jelly in the sump problem which has been reported by some veggie oil users.
It is up to you what you use v's what you have to lose.
