Biodeisel in the abc news -increase in interest because of Iran war.

[Mandy]

Hello. I just joined after reading the article below. We have a 2003 Toyota Prado deisel. Do you think it could run on biofuel? Cooking oil? Straight and refined or a blend? Any info welcome.

I hope you find it interesting and useful. Terry Woodcroft was a Councillor at ColacOtway Shire in Victoria's South West. His contact info is available online.

If it has the 1KZ-TE engine is should be fine on biodiesel or a twin tank conversion to run on wvo.

Welcome to the forum.
Your question poses further questions.
What engine is in your car?
Ours has the 1kz-te engine for the 2004.
As ours has a long range tank and I was thinking about fuel choices, I'd most likely mix biodiesel with diesel. Maybe a B50 mix.
Otherwise, if it's indirect injection and you prefer veg oil I'd highly recommend a second fuel tank with a veg oil and diesel mix. But this would require some solinoids to switch and possibly a heater as I don't know where you live in regards to temps.
You should do some research.
Also, where were you thinking of getting your veg oil from as I'd imagine competing with other users right now might be a bit iffy.

Mandy the biodiesel that it making it's way into the headlines in 2026 is different from the fuel we have been producing for decades. It is a commercially refined, almost like an oil refinery where the feedstock is ultra processed and the end result is much closer to pump diesel than what we can make - and indeed the claims of a drop in replacement for any diesel engine are seeming to be correct.

You are asking the right questions though and as others have said, your engine is likely to be a 1KZ and a good contender for biodiesel, or a blend, or a two tank conversion depending on what suits you and your planned usage
