diesel alternatives Bio Fuel

Just noticed that a question was raised in another thread about Diesel Alteratives, Bio Fuel, Vegetable Oil

Thought it would make an interesting thread.

Does anyone have any experience of this, My Kontiki runs at about 26 miles to the gallon so I would be very interested in any ways I can reduce the cost solong as it does not put the engine at risk.
 
I have thought about it but considered it too big a risk to take. I do about 5,500 miles a year @ an average of about25 mpg, so savings on fuel against the cost of a 5 pot Merc engine,:( too risky.

also, if you were to give it a try, this may not be the best time of year to do so.

Filter

This is a massive subject!!!!.

My advice if you go down this route(I would not)is to always carry a spare fuel filter and the tools and knowhow to change it.
 
Thanks for your interest in this, both your replys of course beg the question why?
Why do I need a spare filter?
Why is it likely to damage an engine?

It seems more and more people are doing it , if it was still that risky would they be doing it? I don't know
 
'Running your car on vegetable oil depends on what type of car you have, direct or indirect, whether its ECU controlled or whether it's a Bosch or Luca/CAV pump. The latter do suffer from wear more than Bosch; however it depends on what you are doing to the fuel supply etc. It will take to long to go into to much detail here; needless to say you can do it. Go ahead!

Good luck!'

This is a quote from a 'convert' to the veggie cause who has gone into it in depth and even he appears to be a bit unsure.

The savings don't warrant the risk in my case and I couldn't be bothered calculating % etc. What if you filled up in late summer, circumstances change and the van is idle for a few months, you go to start it up and it's a paticularly cool October day. There's every chance that the tank and pipes are all waxed up.

Too big a risk for me and I'm a gas adaptor user.:cool:
 
There are too many variables involved in using veg oil. And the risk is too big. End of!

You need a spare filter because Bio is actually very clean,but it disslodges all the sludge and cr*p left by diesel.You usually need to change the filter after 2k or so of Bio use.If you then stick to it its ok.
 
I used to run an old Gwagen very successfully on veggy oil straight out of the supermarket and it was about half the cost of diesel, it ran better and quieter but I was always so hungry when you smelled it, a friend ran his more modern Fiesta van on it and wrecked the pump, I think the older vehicle the better but of course the prices are pretty much the same nowadays.
 
I run my vw t25 on free waste vegetable oil- filtered to 5 microns. 90%+ wvo in the summer down to approx. 25% in the winter.
And yes it does smell like the local chippy behind you.

Do you filter it yourself or do you buy it ready filtered. When I was on b sites driving Komatsu Diggers I met another contractor who ran his diesel van on it at about 50/50 this was 15 years ago. He had done it for years he said without any issues. I could not be bothered at the time becuase the savings were not that great.

How much is filtered oil to buy? Does anyone know?
 
Cheaper?

Proper bio diesel ,not filtered oil which does not suite all diesels,is more expensive to make than regular diesel .
The rate of duty is less which brings the price inline or slightly less than regular diesel.
Most regular diesel you buy at the pumps already has about 5% Bio mixed in.
Bio customers usually buy for environmental or PR "we use renewable power source fuels" reasons not price.
Great stuff if your van has failed its MOT on emissions because it burns cleanly.
Its a complex subject .You get a differnt "Bang for you buck" so direct price comparison ltr for ltr is not easy.
 
hi i used to run a vauxhall cavalier on veg oil, did thousands of miles and never had a problem ,i used to run at 50/50 with diesel and new oil from supermarket all year round ,when i sold it at 150k to a mate he did the same and sold car on again later.i saw the car localy the other week and had a look at the mileage its now done over 200k. the only reason i dont do it any more is because they have made the price of veg oil go up to a price where it is no longer worth the hassle .if i could get the oil at a good rate i would be back on it tommorow.

You answered my next question :) How easy is it to get the oil, I guess everyone is after it now. You used to get loads of it just piled up behind the chippy but not anymore.

Next year (January I believe) the Government wants it to go to 10% bio diesel content. I forget the reason why but a small percentage of vehicles may have problems at this ratio.
 
Hi
There is a place just off the A12 Stock/ Billericay turn off sells Bio diesel for 89.9 per ltr.
 
i too run my tranny engined ldv on waste veg oil,no diff to power or consumption, what i don't do tho' is put it into the main tank.i stripped the old air filter box and put a sports filter on,and put a 6gallon tank in its place. i also built my own heat exchanger too.this time of year or any really your best running 70%wvo and 30%diesel,i use manual isolators too so no electonic bits to go wrong. the main probs people have with wvo is not filtering properly and running it too thick thus causing pump to work real hard,i also have a seperate filter for veg oil.:)


p.s. ready filtered is available on ebay@40/50p a litre, pop round your pubs and indian restuarants
