Vegetable oil is too thick for most diesel engines. There are conversion kits to enable an engine to run on straight vegetable oil. One alternative is to convert vegetable oil to biodiesel, but that increases the cost. The other choice is to blend vegetable oil with diesel.
A mixture lets users get some of the advantages of burning vegetable oil and is usually done with no modification to the vehicle.
[edit] Ratio of Vegetable Oil to Diesel
The following is taken from this source. [1] How much veg oil should you use? Start with a light blend, and increase each time you refill. That way, if you notice your car sputtering, you know you've hit the limit and should use less next time, and you can top up with regular diesel to thin the mixture back down.
- A 10% veg oil blend will work for everyone. It meets your personal part of our Kyoto commitment, and there should be no noticeable difference in how your car drives. 27 liters of diesel and one three-liter bottle of veg oil from the supermarket.
- At 25% veg oil in 75% diesel, your exhaust stops smelling like a taxi and starts smelling like a donut fryer. It's pleasant and a real talking point. You should notice the slight smoothness improvement around now.
- 33% - one part veg to two parts regular diesel - is the heaviest mix one would recommend for the British winter, unless you've got a frost-free garage. This level of blend still starts even on cold, frosty mornings.
- 50% is a good running blend for the rest of the year.
