Run Your Diesel Vehicle on Biofuels: A Do-It-Yourself Manual
I really rate this book, the authors have done an excellent job of bringing DIY-biodiesel-books right up to date. Some of the bestselling biodiesel books out there are painfully out of date, some full of dangerous advice and information, and this is not one of them.
Of course this book is not just about biodiesel, in fact only about half of it is, it brings together all the other options too; such as engine conversion, running on straight vegetable oil or used chip-shop oil, how to convert your engine, how to make biodiesel, how to clean used oil, how to test your fuel is up to the job; it even tells you how to tell the con-men from the good guys and has a small section on "other options" such as blending vegetable oils with solvents.
Pitched at audiences both sides of the Atlantic, neither overly technical or simplistic, the book is friendly in tone, easy to read, hundreds of illustrations and dozens of DIY projects.
As the authors say themselves: "there is nothing in the book which you can't find on the Internet for free" but a book is a much nicer thing to read and the Internet is full of nonsense and idiots who don't know what they are talking about. This book does a brilliant job of separating the BS from the facts.
Highly recommended, whatever your level of experience with Biofuels, this book is the best I have read on the subject.
