Making biodiesel

Making biodiesel is the easiest part of the whole car fueling process. It takes about 2 hours of your time and that's that.
A greater problem is washing and drying your biodiesel which takes days. Of course you don't have to be present all the time, but still it takes a lot of time.
Some of the problems I have found with biodiesel are:
- Methanol (starts to evaporate at 65°C [150°F]. The fumes are heavier than air. Very toxic)
- Methanol can ignite with invisible flame.
- Cold starting problems accur at relatively high temperatures.(around 0°C [32°F] you should start using normal diesel or your filter will plug) - see a forum about this on BioDieselNow.
