oops they did it again

PS. it is carp for starting in frosty conditions so mix 50/50 with diesel in cold weather, or buy a preheater.

Doesn't it just.
Hence the need for a Biofuel receipt. cops and customs can smell them a mile away

Oddly enough, the diesel engine was designed to run on vegetable oils, peanut oil IIRC, and should last longer than using mineral oils.

Except modern diesel engines are designed (funnily enough) to run on the less viscous fossil fuel known as diesel. So the high pressure pumps suffer.

Some rubber materials perish in contact with vegetable oil and some seals will fail.

Also, veggie oil produces a lot of gunge when it burns that will make the engine sticky.

"Your cold starts will begin to deteriorate, your filter will probably start plugging, your injectors will get coked up, setting the stage for ring sticking, glazing of the cylinder walls, increased lube oil consumption and eventual engine failure -- if you can continue to get the thing started in the morning. More than 20% or so veg-oil in the diesel is not a good plan for more than short term 'experiments'."

There has been much debate as to the suitability of using vegetable oil in diesel engines and a considerable amount of confusion as to whether these oils can cause damage to engines. This database will help us decide which engines can be run successfully by looking at actual use on the road, as opposed to laboratory tests. We would like to identify vehicles that run particularly well by rigourous statistical analysis, which will be available free to all, on this page.

Some initial conclusions: Lucas pumps are not performing well on high doses of vegetable oil. This pump should be avoided. Other problem areas are related to computer control systems (TDi, HDi, CDi etc.)which have an array of sensors reading temperature, flow rates etc. These sensors seem to get confused by the thick oil and instruct the fuel system to go into safe mode, resulting in loss of power. Some sensors seem to get completely destroyed by the oil, resulting in an expensive replacement pump. Another problem is with electric lift pumps which operate prior to the main pump; if these pumps fail the main pump can run dry and fail as well. Also, it seems that people are not very forthcoming if their vehicles have failed so we are more likely to here about the success stories than the failiures. One of the objectives of this database is to identify vehicles that have problems so that people need not repeat the same mistakes.

Redex Diesel treatment once a month.
My mate has been running his Transit for 2 years on it and no problems yet.
if it starts to play up. chuck some diesel in it and find some sucker to buy it

All this negative stuff is put about by the oil companies anyway.
Oil companies = all your money belong to us

DimPrawn: Good post, good link. I stand corrected. Triglycerides vs Alkanes. Should have though of that.

[milanbenes]

Diver,

you didn't answer, what engine are you putting vedgetable oil into ?

As for your comment,

Frontera 2.2

LDV 2.5

[milanbenes]

ok, the LDV has the Perkins engine, but those engines were carp and always blew up after 100,000 miles.

is it ex post office with the sliding doors ?

frontera 2.2 is that an isuzu diesel ? if so should have a good long life

My vehicles are diesel.

Vegetable oil in Tesco = 37 pence a litre. smells funny but the engine runs just as efficiently, and you just pour it straight into the tank.

Or so you've heard you mean......
