The first thing that you need to do to get started is to decide whether you want do convert to biodiesel, which is a fuel created from recycled oil like restaurant grease, or whether you want to use straight vegetable oil (SVO) like corn oil. Do your research on the pros and cons of this type of conversion. Biodiesel is very cost-friendly, but it can be hard to find renewable sources of used oils and fats. Some areas have not caught on to the bio-diesel craze and simply do not know how to donate or recycle their used oils and fats.
Straight vegetable oil can be bought right at the store, but this method can sometimes be unstable, since different oils have different properties. It can also be more expensive, depending on the oil you use. Be aware that both of these methods can cause disastrous damage to your vehicle if you are unsure about what you are doing, so either consult a knowledgeable expert, or convert a car that you do not mind sending to the scrap yard, should your conversion go awry.
The good news is that both of these conversions will have an improved impact on your carbon footprint. Many people want to leave a smaller carbon footprint, by using less energy, more effectively.
Once you have decided how you want your car setup you need to start small, and get your process down in small quantities, working out the kinks and possible mistakes, before you move to producing large batches. Do not just convert your engine and attempt to drive cross-country and expect to make it very far. First you will need to do a few test runs with your production methods if you are creating Biofuel. Sticking with an amount around one liter is a good size to start with.
It is very important to remember when you are starting a new batch to only use, fresh new oil. Using used oil is a little bit trickier, and novices might produce a batch with used oil that might cause damage to your vehicle.
Methanol, lye, and alcohol are the three chemicals you will need to get when producing biodiesel. All of these are easy to find at most automotive stores or chemical supply houses. Use caution when using these chemicals, since they can cause injuries such as chemical burns, eye damage, and damage to surfaces of flooring, upholstery and paint. Also these chemicals can have strong fumes, so working in a well ventilated area is recommended.
To use straight vegetable oil, you will simply need to get an SVO conversion kit designed for use with your car's engine. Once installed, you will need to identify a continuous supplier of vegetable oil, so that you do not run out. Once you are done with these initial steps, you are ready to roll out in your newly converted car.
