biodiesel

[K7ERG]

Anyone using biodiesel in their ael?

[Henkjan]

no, I don't eat that many chips

[spink]

not for a while but over the last 5 years I should think I have put 2000 litres or more through mine.No problems,apart from a slight smell,there used to be a very good saving to be made but recently its been over £1 litre and I don't do anywhere near as many miles as I used to so not so worth the hassle for me personally(had to drive 20 miles round trip for it)

Easier to buy fresh oil from Costco or Makro's. Works out at £1 per litre and just mix it 50/50 with diesel. That way you don't have to hope that the stuff you are buying has been properly processed.

Diesel filter ok. As I have heard it cleans the fuel tank and block filter.
Was thinking of.making my own but have since found a source for around what I could make it for.

I ran my passat 130pd on it. In the summer I put in 70% oil 30% diesel winter 50/50. Never modified anything and never had a problem. Economy was down when I used more oil but power felt better. I just bought it from local food wholesaler and it was 8.99 for 20lt at the time!

I have a mate who is developed his biodiesel. Has additives for up to -20 and all oil is checked before and after process. Going to pick up some tonight. Half price diesel.....

I give a lot of oil from work to my mate, he heats it up to about 140 degs to evapourate off the water in it, then filters it down to 1 micron.
Runs a 70/30 mix with diesel and works well but he has the change the fuel filter every 3-4k miles. The next stage is to then use lye as a catalyst and add methanol then wash the oil to remove the glycerin and other crap. then you can run pretty much 95% bio.

He has found this side helpful.

Its the glycerin thats a problem, all depends on used or new oil also. I had used oil for 5 years in both Bosch Pumps Rotary and Bosch VP37 Fuel systems, Lucas / CAV and common rail aren't happy with bio.

Think the duty rules have change now also, but not surewhat ! Back when i used it you had something like 2000 litres allowance before having to declare for tax reasons.

[K7ERG]

it was 2499litres then has to declare tax. Will have to check again. I will also be using pump diesel so nowhere near that.

[K7ERG]

My findings I would say engine starts easier, runs smoother and I would say more power.
The smell not the best with a screamer pipe..............

[spink]

have you got the 230s in yet?

[ian4455]

cetane level in diesel is typically 45, veg oil used can be 45 - 65 so it will run better, more power etc. Less knock noise also and better lubrication properties for you pump cosidering we're all now on low sulpha diesel in the UK.
