I want to know about how to make biodeisel?

Question

I am making bioeisel fuel oil from used cooking oil and need to know whether it would be cheaper to use ethanol to make it and whether it would be as good as methanol for just fuel oil not deisel fuel for trucks.

Answer 1

DO NOT USE gasoline or ethanol in a diesel ,or u might blow up the motor. The cooking oil must be filtered so there will not be anything to block your injectors.

Answer 2

Here's my small-scale biodiesel recipe:

1.) Put a quart of vegetable oil on heat

2.) Mix in 1 cup of ethanol or methanol (I use vodka)

3.) Stir that for 20 mins

4.) Put that in a blender for 5 mins

5.) Let it sit for 24 hrs

6.) Skim off the top white layer

7.) The bottom clear part is biodiesel

If you have lye, mix a little in when you add the alcohol.

I use this all the time, you may need to experiment though.

Answer 3

Here are two good sources to look for some answers.

Home power has plans to do it all.

Mother Earth News has plans, links, books, ect.

To me it looks like is easy to make ethanol and the lye to make it at home.
