the warranty will be void, not worth it.

Are these people making bio diesel properly? All these problems sound like impurities to me.

Use a bio diesel generator for the power to make the fuel, then it is worth it.

Ok the machine may cost a couple of grand, so you need 4,000 litres of waste cooking oil to break even, then it is more or less free! I wish I had the capital.

Why not sell the rodeo, get a cheaper truck not direct injection, pre 2001, less tax, and get a bio diesel making machine?

Found out about the goo in bio diesel...

They have left out the last 2 processes in making the fuel. They need to spray a mist of water over the fuel and let it settle through for a few hours to wash the fuel, and then remove it. It needs to be filtered again and cooked at 55'C for 3 hours and filtered again.

The stuff in the filter on the vehicle is a kind of soap, which should not be there if the fuel is made properly. The water wash, (to remove the soap and crud) and heat treatment take time and energy, so people leave it out to save money. Shame really, I would say your bio diesel supplier is ripping you off for the sake of a few hours and an extra £0.60 of electricity (for heat) per 50 litres of fuel.

The whole point of bio diesel is that it is the same as fossil diesel. Don't use veg oil in DI engines!

Glycerol is removed earlier in the process.

The soap is in small amounts, but after a few tanks collects in the filter. There was someone commenting on finding a fatty deposit in the bunged up fuel filter, this would have been soap.

I don't know what SVO is, take it means Something Veg Oil. The problem, as far as I can work out is due to the viscosity, it puts a strain on the pump and can muck up the injectors. You don't get a problem with it mixed with diesel or bio diesel under 40/60. There have been people with expensive problems that manufactures have been able to prove that veg oil is the problem, and the warranty is invalid on grounds of wrong fuel.

Some engines are designed to run best on old dirty high sulphur diesel, they haven't kept up with the cleaner fuel. I know of some DI engines failing after 80,000 miles, rather than the 600,000 you might well expect. Not Isuzu though.

You can run a gas BBQ with petrol under pressure, doesn't mean it is a good idea!

Old tanks will run on fuel oil, veg oil, diesel, powdered algae and proberly treacle, they were designed to. Modern DI engines are newish, and a bit fussy. I don't know how long they will run well on SVO, but they are not likley to keep going for ever, and what if it gets below -5'C and turns gloopy?
