Hi everyone,

After successfully using biodiesel in various diesel vehicles, I am takign the plunge and putting in a 50:50 mix of bio to derv tomorrow. I am interested to see who else is using bio in their td6. There are multiple BMW 330d drivers using it with zero problems.
I must stress that the bio is of excellent quality.
 
How are you getting on with your new purchase, after all the ummmm-ing and ahhhhh-ing??
 
:eek::eek:

Let us know how you get on :S

I though these modern engines are really fussy on fuel
Hopefully it won't be any expensive fix for you lol
 
I love it Saint v8. No problems touch wood! Although rear parking sensors are a bit mad at the moment, strangely they work fine in the rain- don't think they are dirty though!
 
Yer, went for the diesel. I have my own bio kit, so it made sense.
I will let you all know how I get on. BTW, hippo what mpg do you get?

If it's properly refined Bio diesel as opposed to straight veggie oil then it should not be a problem. If the lye that's used to remove the glycerides is effective and the result is non corrosive it should be no different to the mass produced stuff that's running common rail diesels in buses over here.:)

Nice ;)
Although the gm boxes are weak I still prefer diesel engines
And the roar they make when you put your foot down ;) lol

I get 22MPG chipped

What's your mpg showing at the moment then ?

I reset every tankful. The worst I have got is 22.7 mpg, and the best 28.5 mpg. Not bad for the size of the thing!
Running 50% bio will mean the equivalent of 45/49 mpg! I agreed datasharp, there is so much paranoia about biodiesel. The reality is that most small forecourts selling regular diesel have loads of water, grime, grit and rust in their ancient tanks!
 
Thought I would update.... put 25 litres of bio in with £40 worth of diesel. Running lovely, slightly smoother is any difference!
 
I'm playing it safe with the first three to five tanks. Then will consider going to a higher percentage. I'm rolling with the equivalent of 48mpg now!
 
No change in performance, and less sooty smoke under hard acceleration. I'll change the fuel filter in a couple of weeks as the first time it is used, it will clean the fuel tank and lines which will deposit in the filter.
Chuffed!

Nice one mate

Can you not run it on straight bio then ? Or has got to be 50 / 50 mixed with diesel ;)

See my earlier answer, properly refined bio-diesel should be OK straight but a mix must be safer. Straight veggie oil will kill it:eek:
 
I quite agree datasharp, straight veg oil would just knacker the injection pump due to the viscosity. But proper bio is as good as derv IMHO.
Only problem is that waste oil is turning from a waste produce that restaurants used to pay to dispose of, into a commodity. I now have to pay £5 per 20 litre drum of old oil. Not a lot I know, but it is only used chip fat!

Check to see if the paint is bubbling on the parking sensors. The aluminium head on the sensor corrodes and distorts the signal. I'm guessing it leaves an air space in the corrosion that gets filled when the air is damp.

If so scrape it off, sand the head and see if it has gone away, then touch up with grey primer and touch up paint.
