diesel, bio, chipfat, rapeseed??

LOL, I thought I had missed something as i skimmed the article and added my bit

Something tells me to give it a go and then I think about the Veg oil slushing around in my tank and i get put off. i don't know perhaps its a drip fed impression that diesel and modern cars are very high tech. But its only a little diesel engine, ok the electronics are modern but isn't it just a simple diesel underneath??
 
Pukka biodiesel is great stuff, but the trick is finding a good supplier - a lot of places don't make or supply stuff that's pure enough.

I had a very bad experience a while back that ended up in Trading Standards getting involved, but also, had a good experience with a place on the outskirts of York.

Properly made biodiesel is actually better for your engine as it has better lubrication properties than fossil diesel too.

Let's put it this way: if there was a local supplier selling top-notch biodiesel and it was the same price as fossil diesel, I'd buy the bio!

Cheers,

Well I have been running my A2 on approx 50% biodiesel (top up to half tank with dino diesel then run along to the bio place to fill to the brim) for the last few months and had no serious problems. Same MPG and no discernible performance difference.

The only problem is sometimes it does not start first time on a warm engine but it goes back to normal starting on 100% dinodiesel. Anyone know what might cause this?

The place I get the biodiesel make it themselves from waste vege oil from local resturants etc. The problem is they say that they may not be producing it much longer so I reckon I will try making the stuff myself. There's loads of info on the net on how to do it.

Since there's no duty payable for up to 2500l/year, by my calculations that would mean that I could travel about 30000 miles per year duty free if I ran on pure biodiesel :cool:
 
Make sure your bio diesel meets the RME / EU standard and you won't suffer from the issues posted.

In Winter mix with normal diesel 50:50 at least.

Summer gernuine washed and filtrated B80 to B100 should be ok.
 
The guy at the head of this post mentioned using BP or Shell diesel only, does this make a difference to the performance and well-being of the car? I've only had my 1.4TDi a few weeks (my first diesel car), but so far I've just been filling up in Tesco's/Sainsbury's with their 'CityDiesel'. There wasn't many others filling up with this stuff even though the forecourt was busy, so I did wondered exactly what sort of quality this juice was, and did everybody know something I didn't...! Are there cold hard scientific facts why I should use brand diesel? Will it improve mpg?

Thanks,

Jon
 
Make your own Biodiesel

Thought I would throw this into the mix. They call it the freddy it costs 1500 quid and you can produce upto 500 litres of biodiesel a week for about 20p a litre. So it would be about the same price as a 2 tank system with heater, but with this system you can use the biodiesel in other cars, friends family etc. I rekon if the goverment keep the 2500 litre duty free limit on biodiesel it would pay for itself within 2 years. I need to make enquiries into getting the used oil from chip shops, they would view it as waste I think so it shouldnt be such a problem. Has anyone heard of the "freddy" or reasearched into this more than me? I await to be shot down in flames, but this seems to be an excellent idea. check it out at

sorry iv'e only read half the posts so i may be repeating something already mentioned.
my company runs 6 diesel vans plus a few diesel cars.
for the past few years i have been experimenting with different oils and this is what iv'e learned.

it is totally legal to run on cooking oil up tp 2500 lts a year.
in the winter the cooking oil thickens considerably particularly close to zero degrees, so don't mix too much.
in the summer 50/50 cooking oil to pump fuel is usually ok, in the winter i mix less, like 75/25.
heating oil runs fine but it has very little lubrication quality so be carefull.
cheapest new oil is costco, currently £13.95 for 20 lts.
all cars are different, so start lightly if it splutters you're pushing it so be carefull, diesel pumps are expensive like often well into four figures.
i have not tried used cooking oil but i have been told it runs better, tests due to start soon!

Straight cooking oil mixed with diesel is a no no as far as I have read, you need a two tank system.

My experiments with home brew biodiesel are going well, I'm just making small 3 l batches so far but it works a treat.

Ian Mac, I have looked at lots of biodiesel processors on the net, lots of them look very expensive for what they are. DIY is the way to go for a quality processor. All you need is an old hot water tank, pump and plumbing skills see GL processor. I reckon I will be making one of these in a few months. :cool:
