Biodiesel (waste veg oil)

[fronteratech]

if you read the facts you can make an informed decision on them its up to you remember VW and Peugeot are printing “not for biodiesel” and citing the use of a Diesel Particulate Filter (DPF)

The reason dpf cannot re generate without diesel

you keep quoting the goverment and we all trust the goverment

100% biodiesel and higher percentage biodiesel blends can cause a variety of engine performance problems, including filter plugging, injector choking, piston ring sticking and breaking, elastomer seal swelling and hardening/cracking, and severe engine lubricant degradation.

I give up. :shrug:

Most of the stuff he links to was published over a DECADE ago. :bang:

 

[fronteratech]

only adding to the debate dont want members not knowing the pros and cons on biodiesel

The fiat article from new zealand is most pertinant on here

<H3>Diesel

Use only Ultra Low Sulphur Diesel Fuel. Fiat only recommends the use of Ultra Low Sulphur Diesel (USLD) that complies with the Fuel Quality Standards Act (FQSA as at 1 January 2006) in Fiat vehicles fitted with common rail direct injection diesel engine. Using the incorrect grade diesel fuel will cause running anomalies, possibly activate warning signals and also possibly cause component damage. Consult your fuel reseller when refuelling if in doubt.
Bio-Diesel Fuels

The inconsistent nature of Bio-Diesel fuel, typified by large particulates and various contaminates, can cause severe damage to the various components of common rail direct injection diesel engines. Any bio-fuels must conform to the standard EN590.
Alfa Romeo DOES NOT recommend the use of Bio-Diesel fuels that can't be certified to this standard. Any consequential damage caused by the use of Bio-Diesel fuel will not be covered by the manufacturer's warranty

i wonder if using wrong fuel is why this https://www.fiatforum.com/tech-talk...car-fitted-dpf-diesel-particulate-filter.html

My guess is possibley as the DPF was already clogged with the soot from DinoDiesel.

This will help explain the effects Biodiesel has on a DPF.

Thats a good point some fuel manufacturers use different concerntrations of bio

On an older vehicle than present would run on TESCO diesel but current one only runs well on none supermarket diesel

Also noticed that with non supermarket get better MPG about 5 mpg more

The other argument is why pay the same for diesel with Bio mixed into it when you can buy proper diesel with less BIO
This is sometimes why supermarkets are cheaper like putting more juice in a tin of beans than beans

To be honest if cars would run Ok on bio without modification or extra servicing everyone would have a bio diesel refiner at home

And it would be at the pump cheaper than normal derv


I have heard the argument that Rudolf diesel ran his first engine on peanut oil therefore it will work

But that was before electronics and high pressure diesel pumps

T14086But do the chips taste good

Yes smells just like a chipshop following something running on bio

It already is. Its being sold at an old filling station near me for:

73p a litre for Biodiesel made from waste veg oil.

93p a litre for Biodiesel made from new/unused veg oil.

hey fronteratech.

Think you need to do a little more research. A good start would be to get your head from up diesel bobs arse. His name is diesel bob not diesel god. :nutter:

absolute rubbish!!

you are getting confused with running on unprocessed waste veg oil and processed waste veg oil (biodiesel) (as with most of your comments)

there is very little smell to biodiesel and it does not smell of any food substance (more like linseed) your welcome to come and stick head up my exhaust with a bag over it - just to prove the point.

"Never argue with a fool, they will lower you to their level and then beat you with experience"

Dont bother, the :nutter: aint worth the effort.

 

[greenmachine]

just had MOT done the exhaust emissions were as follows:

test limt applied: 1.50 l/m
absorption coefficient: 0.87 l/m
zero drift 0.01 l/m
absorption coefficent after correction: 0.87 l/m

how does this compare with standard diesel?

thanks chris

As said before gave members the information the information is correct in respect of fuel pump lubrication

One car run on supermarket part bio diesel pump fails at 42000 miles

One car with tnk conversion running pure bio three fuel pumps in four years

One car running non supermarket from 40K still running at 100K

All same models all same vp44 pump

The later fuel pumps have fuel coolers fitted to cool the fuel due to high pressure pumps compressing hence it gets warm compress liquid resultant heat.

Heat in fuel damages seals and electronics

Also reduces economy

I'm still on a 1:4 blend with waste veg oil & have noticed the chip shop smell - but I would rather that than the usual smell from diesel exhausts.
The oil itself does take on characteristic smells depending on what food is cooked in it. Good chip shops should never cook burgers in the same oil as other foods and they should use fresh oil as often as possible - some shops simply reek of well-burnt oil

have i read this wrong?? sorry if i have but how do you compress a liquid?

maybe thats why my brakes feel spongy as the brake fluid is getting compressed when i press the pedal?

Or maybe you are driving a 2007 skoda fabia ?:devil:

Thanks for the PDF document.
Not sure how it relates to compressing a liquid though.

You can put three identical machines side by side & run them in exactly the same way year in, year out & you will always have one or two breaking down more often than the third. I worked in maintenance in a nursing home. in the laundry we had three identical machines, all installed from new, all drawing water from the same softener, all drawing liquids from the same drums - yet 1 & 2 were constantly breaking down - mainly the sump/drain plug sticking and belts breaking. It got so bad that I replaced all the screws holding the rear and lower panels with bolts/wingnuts for easier access. but why did #3 never break down?
It got exactly the same use as the other two, the drums had inbuilt scales to ensure they weren't overloaded & they all ran at the same temp (due to infection control).
The sump/drain plugs didn't stick because of limescale inside, it was the gearing & springs on the outside which stuck & as for the belts, i had the pulleys off & checked for sharp edges or varying depth/width but could find no reason for belts slipping off or breaking.
Actually, just remembered, machine # 3 always had a problem with the filler jets blocking & not getting enough liquids into the drum. fortunately, the filler had a glued on lid so after carefully cutting it off, I was able to refit it with some long thin bolts holding it together - for easier future cleaning, I also bought a really cheapo toilet brush & warmed the handle enough to bend it so the laundry woman could give the jets a quick scrub at the end of every day.
