Biodiesel catalyst

Hi everyone,

I've heard that regular non-leaded petrol can be used as a catalyst
in making biodiesel. Is this true? And if so how does it compare with
other substances?


2 x Land Rover 110 w/200tdi ('88-'90), Ford Fiesta 1.8 diesel ('96), Ford Transit n/a 2.5 diesel ('00), (they should all run well on veggie, and I plan to find out!).

Unleaded can be used to thin biodiesel in very cold temps to stop waxing.Not aware of any recipie to make biodiesel using unleaded as the catalyst.

There is a video up on youtube from a Top Gear episode where the guy just pours 15% petrol in the veg-oil and lets it settle with or without stiring, then fires up a diesel car (Volvo).

Is this for real or just more Jeremy Clarkson BS?

Looks like just another take on blending to me.

Does the "white spirits" really thin out the veg oil? If so, translating English to English what would white spirits be in the US?

White spirits is sold in the UK as a cheaper alternative to turpentine (turps)for paint brush cleaner-I think it is similar to paraffin(which I think is kerosene over your side of pond).How well it thins veg,I don't know.Most of my friends who run veg just thin with unleaded.hth

What you are seeing there is veg oil thinned with unleaded to make a biofuel,it is not biodiesel.
Veg oil thinned with unleaded is real,but must be dewatered and filtered (if using used oil)first prior to adding the unleaded,and is only suitable for certain injection pumps.

I "assume" older mechanical pumps are the certain pumps.

He was saying 3 ml per 100 ml. or 3% unleaded to oil ratio, that seems a little low from what I have read from other posts here.
