Plant DriveThis may be old news, but I thought that they did a particularly nice job. They even have it set up so you can buy all of the products they offer. One thing that I thought was nice, was the article about collecting collecting used vegetable oil. It’s difficult to get out of the mind set that there is a bucket of free fuel behind every Mickey D’s. Some of these diesels are finiky about what you feed them. I always have mine super sized. The FAQ is great too, Check them out!

Here is a link to a nice article from the plant drive site as well as their FAQ:
